57 years ago today - "The Eagle Has Landed"

57 years ago this morning at 9:27 EDT, Buzz Aldrin crawled into the Lunar Module Eagle and began the lengthy process of powering things up for the short mission life of the module.  An hour later, Neil Armstrong joined Buzz in the LM.

A little over three hours after that, 1:47 PM, they released the latches and separated from the Command Module.  At 2:12, Michael Collins fired thrusters on the CM moving it two miles away from the LM.  Except for that small altitude difference, both vehicles remained in their initial orbit from yesterday's lunar orbit insertion until 3:08 PM when Armstrong fired the descent engine to lower the Eagle's orbit. 

What follows is a 20 minute video depicting the landing which is easily the best modern reconstruction of the landing that I've seen.  It combines video from the window as Armstrong would have seen it with the audio traffic from Mission Control.  The first three minutes gives a modern simulation and animation of how it all worked; after that, it goes to the view recorded on the LM with spacecraft communication on the left speaker and mission control intercom on the right.  Yes, I think it's worth the time.  

The LM touches down at 4:18PM EDT.

At 6:00 PM, Armstrong radios down to mission control that he recommends they start the EVA (Extra Vehicular Activity) sooner than planned; at 9 PM.  Although they don't make the 9PM goal, the 10:39 beginning of the EVA is still five hours earlier than the mission plans.

As I've mentioned elsewhere, this was the last vacation I would ever take with my parents. July of 1969 was the summer between my 9th and 10th grade years of school, and I was 15 years old. Like millions of people around the world, I hung by the front of the black and white TV; this one in my uncle's house in New York City.  We watched intently but I don't recall exactly how much we saw or if we watched until 1:11 tomorrow morning when the EVA officially concluded. It's a sobering thought how many of the family members there on that historic day and night have passed away. Both of my parents, my uncle and aunt, and I'm simply not sure how many else. 

Over the years, this meme from Aesop at Raconteur Report has become my default way of thinking of the Apollo program itself. While he clearly means the landing of Apollo 11, I can see the entire Apollo program as a strong contender for the Peak of Western Civilization.

Weekend wrapup

As I mentioned in Friday's post, this weekend was the CQ Worldwide VHF Digital Contest, only I described it incorrectly. Or incompletely. 

CQ Magazine has been running a July VHF contest for years, but with the rather amazing rise in popularity of the digital modes (which I know I've talked about before) a group of hams who prefer the "good old" analog modes like voice, mostly single sideband (SSB), with a small amount of FM, along with CW (Morse code) have been finding the contests much less interesting, and I've read that a noticeable number of these operators have stopped participating in the contests. This year, CQ introduced a new concept: a second contest.  Enter the one you prefer or both of them, your choice. The "CQ Worldwide VHF SSB/CW Contest" was held in the first weekend of July with the same 24 hour interval as yesterday's VHF Digital Contest 1400Z, Jul 4 to 1400Z, Jul 5. No, I didn't participate in that. 

So how did it go? Miles better than contest I keep comparing to, last year's ARRL VHF Contest. With the start and end times for this contest being in the morning, it tends to help to remember that propagation will be toward the sun, with paths in the sunlit part of the day. In the mornings, we'll hear the eastern part of the US, and as far as into Europe we can (if we're lucky), while in the evening we'll get more openings to the west. My perspective on open to the west is that from here on the east coast of Florida, pretty much everywhere is "toward the west." That's how it went, only the opening toward the west coast was over pretty early, long before it was sunset on the left coast.

The two pieces of software I'm running and depending on the most are a second-source of WSJT-X, called "WSJT-X Improved," and a program that helps with human interfacing to WSJT-X improved called JTAlert. Describing how to connect them and even get started is "beyond the scope of this paper" (as they used to say). JTAlert's default display puts up a box where incoming messages are tagged so that we can tell at a glance if we've worked that station before, the station's grid square designation, notes if they're calling CQ or a few other things. When that display window contains a lot of calls, it can be hard to read what I need to get out of it in the 15 second intervals FT8 uses. For much of the contest, that window contained 40 to 60 calls in every 15 seconds. Somewhere in that 40 to 60 second interval is where I'd run out time to read it all.

So how good was the weekend?  During the 24 hours of the contest, I only worked two new grid squares (where New simply means I haven't worked them before). That's more or less a "Meh" result. This morning, while 6m was open to Europe, I nudged my number of countries worked up to having worked my ninth band DXCC (100 countries worked on each band). Needless to say, I haven't got 100 confirmed, and can't apply for that wallpaper until I get the 100 QSLs. In my work toward the 8 band DXCC I have now, I've just come to know I need to work a bit more than the 100. Five or 10 extra is generally plenty. 

This afternoon, with the contest over, I worked two more new grids, making the weekend total four. That's not remarkably great, but it's a good day. Certainly more than average. I'm trying to work new ones all the time and I know I've gotten two or three in one day several times. Of course, the more you have worked already, the fewer there are left to get in one day. 

This story about 9BXCC fits nicely with the idea of a post about QSLing, which seemed to get a positive reaction.  

And since this needs a picture here...

Spread that ketchup around

Some catching up on things.

Flight test 13 correction: 

FT-13 is currently set for Monday evening July 20th at the same launch time of 6:45PM EDT so you can correct for your own time zone. That time has been posted since first time I looked for it, around 8:00 AM this morning (EDT), so I assume unless something major happens, it will probably be shown at least until midday Monday unless something really bad is found - or happens - this weekend.

The launch window is 90 minutes long, but as we learned yesterday, that's for holds that might be needed early in the countdown. A hold at an earlier time might be able to use that hour and a half window, but I think it's the fuel loading - which starts at about 45 minutes before the planned liftoff - that says they're done for the day.  

Could be another touch and go weekend here

Back in June, I let all my fellow hams who don't keep track of this know that the annual ARRL VHF contest was coming and I'd be trying to play it hard in the radio room. It turned out to be pretty much a waste of time

It's not-so-instant replay time. This weekend is CQ Magazine's big contest, and WA7BNM's Contest Calendar shows it this way:

CQ Worldwide VHF Digital Contest: 1400Z, Jul 18 to 1400Z, Jul 19
  Geographic Focus: Worldwide
  Participation: Worldwide
  Mode: Digital
  Bands: 6, 2m
  Classes: Single Op All Band (High/Low/QRP)

Rover
Multi-Op
  Exchange: 4-character grid square
  Work stations: Once per band
  QSO Points: 1 point per 6m QSO
2 points per 2m QSO
  Multipliers: Each grid square once per band
  Score Calculation: Total score = total QSO points x total mults

You'll note that the times are very unusual. The contest starts and ends at 1400 UTC, or 10:00 AM EDT. Starting at 10:00 AM would have been great today, so it looks like propagation might be better than the ARRL June contest - at least it looks that way at the moment. On the other hand, ending at 1400 UTC, making it a 24 hour contest, could well be shutting down before propagation gets good on Sunday. 

QSLing used to be quite a bit simpler in the "old days."

For non-hams that statement is as useful as if I spoke it in a strange language, while the hams will understand it. Q-signals are three letter messages that all start with letter Q, and are a shorthand way of transmitting common questions and answers, borne out of having to transmit every letter in Morse code. There's a couple of handfuls of Q signals in common use, and QSL has got to be one of the most commonly used Q signals. The precise definition is a little wordy, but a common reference says. 

I am acknowledging receipt. - ("QSL" as a statement)
Can you acknowledge receipt (of a message or transmission)? ("QSL?" as a question)

From acknowledging you received what another ham sent you, it evolved into a postcard or even letter confirming the contact, and what became known as "the final courtesy" of a radio contact. I remember sending and receiving QSL cards long before I got my ham license ("ticket") as a postcard with a 5 cent stamp on it. 

As with so much else in so many aspects of society, the computer age changed QSLing greatly and while 20 years ago, all options involved sending a physical piece of mail (postcard or paper) now we're flooded with options for electronic QSLs or eQSLs. 

I was considering writing a little summary on what options I see and what I think of it. Does anyone want to see something like that?

Several minutes later...

FT-13 scrubbed on the pad at engine start ... and rescheduled already. 

This screen grab from SpaceX's page for the mission was at 7:40 PM EDT, so less than one full hour after the abort. 

Image

Judging by SpaceX having looked closely enough to decide they can go tomorrow in that little time, I think that means they considered it didn't look like something that required a lot of unexpected work. There was speculation on the NASA Spaceflight video coverage that it might require replacement of as many as four Raptor3 engines. How they came up with that number isn't something I can answer. 

SpaceX's page is the only one I could find with this information.  


EDIT 7/16 @ 10:30 PM EDT, 0230 UTC: A re-check of SpaceX's page for the mission shows the date and time I circled in red are gone, and now it just says "TBD" So cancel this and we'll keep our eyes open.

I may have just hit the point where I say, "don't launch that"

It's a first. Someone wants to do a wide-impact study in space and I may have just hit the first time I've ever wanted to say, "I don't think that's a good idea." Maybe one test flight, one experiment, but I'm not ready to say "sounds great! Go for it!" Neither am I ready to go sign up to protest their launches. 

The story appeared in several places today such as SpaceWeather.com that the Federal Communications Commission (FCC) had recently granted approval to a startup company to orbit a test mirror that's intended to reflect sunlight to parts of the world that going through their night. 

Last week, the FCC authorized Reflect Orbital Inc. to launch a huge space mirror named “Eärendil-1.” From an orbit about 625 km high, it will cast a moving, 5-km-wide patch of light onto the Earth about as bright as a full Moon. Later, the company could combine beams from multiple satellites to create much brighter spotlights. Reflect Orbital wants to launch 50,000 more by 2035, selling sunlight-on-demand to solar farms, construction sites and search-and-rescue teams. 

In case you missed it, astronomers - both hobbyists and professionals - have been complaining about not being able to take time exposures without catching reflections from satellites pretty much since SpaceX started launching Starlinks. Those complaints have been blamed on them, but Starlink satellites aren't the same size as that 50,000 mirror constellation that Reflect Orbital is talking about doing (Orbital Radar says there aren't even 10,000 Starlink satellites in use today - there are 9,532) - and neither are the Starlink satellites as big as those mirrors that Reflect Orbital is proposing. 

Image

If Reflect Orbital's plan is realized, it could be calamitous not only for astronomy but also for the natural world as a whole. Nocturnal animals and night-blooming plants, tuned by evolution to the rhythm of day and night, would suddenly find their darkness interrupted by moving pools of redirected sunlight. Small favors? Reflect Orbital says the light will not be bright enough to start fires.

The FCC acknowledged that there are concerns about this but replied with a limp, "... optical astronomy and the environment lie largely outside their jurisdiction. They can only regulate the project's use of radio signals." Apparently, no US agency regulates how bright a satellite may shine. The EPA (Environmental Protection Agency) is known for ruling with intelligence and accuracy about as often as "pigs will fly and the Earth will fry" to borrow a line (Snookeroo), so I'd hate to get them involved. 

One of the odd aspects to this is the fact that they're reflecting sunlight down. I'd be less concerned about lasers because they're monochromatic, and I'd be rather surprised if as many "nocturnal animals and night-blooming plants" reacted to a monochromatic laser as would react to reflected sunlight.

What we know about Flight Test 13

The short summary seems to be it's an attempt to verify every fix for every problem from Flight Test 12. The current schedule is still this Thursday, July 16th, NET 6:45 PM EDT 5:45PM local (CDT) or (2245 UTC)  The launch will be from the new Pad 2 at Starbase Boca Chica. 

The most notable change is the inclusion of real, functioning Starlink satellites inside Starship’s cargo bay. SpaceX previously tested the ship’s payload deployment mechanism using simulators mimicking the mass and dimensions of the company’s next-generation Starlink Version 3 broadband satellites.

Like FT-12, this will partly be a test of the "Pez dispenser" approach to carrying the V3 satellites into orbit. The majority of the satellites deployed will be Size and Weight mock-ups simply to provide weight and mass properties of the Starlink V3 satellites to test the Pez dispenser. The first couple of satellites will have more electronics than the mock-up V3 satellites will have,  but the source article on Ars Technica doesn't give exact numbers for mock-ups or real V3 satellites. SpaceX's website for the mission says there are six satellites of the 20 modified for tests. 

The satellites will not be part of SpaceX’s operational network, but engineers will attempt to briefly establish laser communication links between the Starlink V3s and other spacecraft flying in low-Earth orbit. If successful, these links will validate Starlink V3’s interoperability with SpaceX’s previous generation of Starlink satellites. 

The overall mission plan is suborbital, just like FT-12 and all the previous Starship flights, and all of the satellites will reenter and burn up in the atmosphere, so there will be a few tests involving the functioning satellites but those are going to be lost.

Six of the satellites have been modified with a suite of cameras to scan Starship’s heat shield and transmit imagery down to operators to continue testing methods of analyzing Starship’s heat shield readiness for return to launch site on future missions. Several tiles on Starship have been painted white to simulate missing tiles and serve as imaging targets in the test.

FT-12 was intended to do a restart test of the Ship's Raptor 3 engines but was unable to attempt that. FT-13 intends to complete restart, which is considered the last major milestone that needs to be verified before going for an orbital insertion. 

Without a doubt, though, the most important part of the mission is how well the heat shield functions. 

“What’s the single biggest remaining problem for Starship? It’s having the heat shield be reusable,” Musk said in February on the Dwarkesh Podcast. “No one has ever made a reusable orbital heat shield. The heat shield’s got to make it through the ascent phase without shucking a bunch of tiles, and then it’s got to come back in and also not lose a bunch of tiles or overheat the main airframe.” [EDIT - change that first use of "No one has ever made a reusable orbital heat shield" to say "rapidly reusable heat shield ..." Musk says that in a different video I've seen - SiG]

“We have brought the ship back and had it do a soft landing in the ocean. We’ve done it a few times, but it lost a lot of tiles, and it … would not have been reusable without a lot of work,” Musk said. “If you want to be able to land it, refill propellant, and fly again, you can’t do this laborious inspection of 40,000 tiles type of thing.”

On this flight, SpaceX will test out modified tiles and attachment mechanisms to gather flight data on different heat shield options. The shield will also have “load sensing tiles” to take measurements as the vehicle experiences higher dynamic pressure during ascent than on previous flights. This higher dynamic pressure will put “added stress on the tile attachments in exchange for increased payload to orbit capability,” SpaceX said.

The thing no one says about Crew Dragon is starting to be said

Six years ago this past May, when Doug Hurley and Bob Behnken rode a SpaceX Crew Dragon from pad 39A on the Kennedy Space center, it was the first time that a manned flight took place from the US, since the last Space Shuttle flight in the summer of 2011. With the safe return of Crew Dragon, the US space agency broke a nearly decade-long gap in its ability to put humans into orbit. 

New readers or people who don't follow this closely may not be clear on this, but when the Commercial Crew program's first contracts were cut, the early winner was Boeing, and their Starliner. Nobody really thought the startup small rocket company, SpaceX would be able to do it. After all Boeing had a massive head start on the little guys and had been a supplier to NASA for practically as long as NASA existed. Since that first SpaceX flight in May of 2020, Boeing's Starliner has not completed one mission, and only made it to the space station one time thanks to a combination of luck and the extreme competence of Butch Wilmore, pilot for that mission.  

That mission was later declared a Type A mishap, the worst level in NASA's failure analysis system, and probably won’t fly another crewed mission before 2028. Based on results so far, it's fair to take any date Boeing issues and double the waiting time.

A complication is starting to attract attention to the lack of a second, proven reliable, vehicle to get astronauts into space. The ISS is scheduled to reach end of life in 2030, and whether or not that's a latest or earliest date for the ISS to be deorbited is somewhat like the old jokes about optimists vs. pessimists. A common theme is that each one sees it their way. 

With the International Space Station slated for retirement in the early 2030s, NASA is partnering with several US companies to develop private space stations. As part of that effort, the private companies will have to work with NASA to determine how they will transport astronauts to and from their space stations, some of which could launch as soon as 2030.

And it turns out this is more difficult than it sounds.

Over the last couple of years, we've run articles on these efforts to develop private space stations. We've seen mention of Axiom Space, Vast, Voyager, and Blue Origin. SpaceX is in a bit of strange place right now considering they're pretty much the world leader in spaceflight. They haven't been contracted to work on a new space station now, and there's apparently belief in the contracting group at NASA that SpaceX is pushing everything they do in the direction of using Starship and "it's too big" for these small space stations. Add to that the fact that there's no agreement to keep producing Crew Dragon capsules 

SpaceX President Gwynne Shotwell has said the company will fly Crew Dragon and the Falcon 9 rocket for a finite number of years, possibly for less than a decade as the company transitions its launches to Starship.
...
“It’s a disaster waiting to happen,” one industry source told Ars about Crew Dragon availability in the 2030s. [emphasis added - SiG]

Needing a replacement for the Crew Dragon implies that they'd like the new one to be interchangeable with the predecessor and that a well-made copy of the Dragon would be an acceptable alternative. Enter a company we've reported on a few times in the last couple of years, the European startup called The Exploration Company.

Last week, the company hosted an office-opening celebration in Webster, Texas, within a couple of miles of the Johnson Space Flight Center. Founder Hélène Huby said her company was considering making Houston the base of its operations to develop a crewed spacecraft.

The Exploration Company has already won funding from the European Space Agency to develop a cargo vehicle, called Nyx, to carry supplies to the International Space Station. An initial mission may happen in late 2028 or 2029. And Huby has made no secret of her desire to build a crew vehicle.

“It’s very clear that in the United States there is a big need for an additional crew vehicle, and nobody exactly knows if Dragon will continue to serve,” she said. “And even if Dragon continues to serve, which I wish it will because it’s an amazing vehicle, then it’s good to have a bit more competition. And also the path for Boeing is kind of uncertain right now.”

Huby is seeking to attract funding both from the European Space Agency and NASA for the development of a crew vehicle, and then to leverage that money to raise additional private capital for a crew vehicle. The company has already taken preliminary steps toward this, which she estimates will require about eight years and $4 billion.

Eric Berger at Ars Technica adds this good summary to the situation.

If this sounds far-fetched, perhaps it should not. Huby has shown considerable skill in working with European space officials to emerge as a leading contender to build a crew vehicle at a time when leaders there have made their desire for one clear.

A Modest Proposal

Over the course of the World Cup in professional soccer and its intersection with America 250, there has been a flood of stories of how visitors, especially Europeans, are viewing America based on what they're seeing and experiencing firsthand. The reports have focused on their reactions to the random folks they've met, their reaction to American food, American portions, and just how different we are than the stories their media painted about how awful America is. A substantial part of that story is that Europe is undergoing a hot weather period, and how everywhere they visit in the US is air conditioned and European countries generally don't allow air conditioning. 

There were stories of power consumption limits in Europe such that if you had an air conditioner, you couldn't set it to cool below 80 degrees F (which probably isn't correct since there's no Celsius or Centigrade two digit temperature that's exactly 80) but the story brings many things I've read over the years. And there were worse stories, of people who were literally made sick from the heat exposure and got in trouble with the law for running an A/C. 

Like most of the people who grew up in the '50s through the '60s, we didn't have central air conditioning in the homes I lived in while growing up. We were fairly early adopters of window unit conditioners because my dad worked on the night shift (US Post Office) so he would get home at around 4AM and needed to sleep until midday. If you've worked night shifts, you'll know that the world gets much noisier as the day gets going, and his answer was to get a window unit A/C that would let him sleep better and longer. A year or two later, older brother got the next A/C in the house and for a couple of years, we'd move my bed into his bedroom so I could get the cooler air, too. That was only over the summer. I think I got a bedroom window unit the year I turned 13. That house never had central air, but they bought a large window unit for the living room and main living area of the house. 

School wasn't air conditioned until I started high school in the '69/'70 school year. I rode school buses and they were never air conditioned. Walking home from school in whatever the weather was is hardly worth noting as part of life. 

The part of the European Tourist videos that resonated the most with me was their surprise at finding air conditioning everywhere. This morning, I watched this video linked from over at Virtual Mirage. The theme of the video is how of all the things we talk about being thankful for, air conditioning is hardly mentioned. It works and works so well that we absolutely assume it will always be there.  

I've long thought that a technologically advanced civilization couldn't exist without air conditioning. Things like temperature and humidity control that allow even relatively simple technologies to flourish are one thing, but the usefulness for keeping hundreds of people comfortable in an office building could be the biggest advantage. 

Perhaps more than any other group, I think engineers will understand that I think we should propose a holiday be created to celebrate the life of Willis Carrier, the engineer who invented the modern air conditioner in 1902. Carrier was asked to create a way to fix a problem in the emerging printing industry. The printing of four color images required four different printing passes, printing with four different base colors. Because temperature and humidity couldn't be controlled, the paper could shrink or expand enough to ruin the pictures. 

Image

Willis Carrier in 1915 - Image Credit Wikipedia

Carrier was put in a situation when the employer he stayed with after inventing the A/C changed their operating mode because of World War I. Seven young engineers pooled together their life savings of $32,600 to form the Carrier Engineering Corporation in New York on June 26, 1915. I think the modern air conditioner company would love a holiday named after Willis, and that's my only second thought in this modest proposal. While I like "Willis Carrier Day" as the name, perhaps Father of A/C Day would be better. I suggest that we pick a day close to what people regard as the first day of summer, near June 1st. When you start your air conditioner for the summer, honor the Father of the Air Conditioner. His birthday, November 26, is a day when Floridians may be the only people who would think of Willis.

Small Space News Story Roundup 83

SpaceX Pulls in Starship Flight Test 13 to Next Thursday 

Perhaps you've heard that FT-13 was No Earlier Than (NET) July 25, two weeks from today, but I saw this evening that the latest schedule is next Thursday, July 16th, NET 6:45 PM EDT (2245 UTC)  The launch will be from the new pad at Starbase Boca Chica, Pad 2. 

The launch is being described as Suborbital on NextSpaceflight, implying that there will be a splashdown off the west coast of Australia. The mission is largely a response to the troubles encountered on FT-12. From their description of the mission

The upcoming flight will aim to complete similar objectives targeted on the previous flight test, which debuted the Starship and Super Heavy V3 vehicles, while also carrying next-generation Starlink V3 satellites for the first time.

Watch “Critical Path”, the latest episode in the ongoing Starship series that followed SpaceX engineers and technicians through the final days before launch of the first Starship V3.

The booster’s primary test objective will be executing a successful launch, ascent, stage separation, boostback burn, and landing burn at an offshore landing point in the Gulf of America. There have been several modifications to hardware and software to address issues seen on the previous flight.

At stage separation on Flight 12, slight differences in engine startup on the ship caused the directional flip of the booster to be off by approximately 90 degrees. The startup sequence has been modified to be more robust to timing variability and more reliably flip in the desired direction, which is done to increase overall performance. After stage separation and the flip, the Super Heavy booster attempted its boostback burn. Five of its 33 engines experienced issues when attempting to re-light causing the boostback burn to end early. The Super Heavy on this upcoming flight has hardware modifications to improve re-light reliability along with updates to engine alarms and aborts to match the conditions seen in the multi-engine flight environment.

As was the case on FT-12, the SuperHeavy booster is expected to hover over the Gulf of America in the vicinity of Starbase before shutting the engines and splashing into the Gulf. 

An interesting topic on this launch is that this will be the first launch of Gen 3 Starlink satellites.  Being Starship and SuperHeavy, it's really surprising they only intend to deploy 20 of these next generation satellites.

German Rocket Builder sets probable August launch date

German rocket company Rocket Factory Augsburg (RFA) lost their first vehicle almost two years ago, while preparing for its first flight.

Almost two years after an RFA One first stage burst into flames during a static fire test, German rocket-builder Rocket Factory Augsburg is preparing for a second attempt at the rocket’s inaugural flight from SaxaVord Spaceport in Scotland, European Spaceflight reports. The launch window will open on August 10, the Spaceport said in its announcement. 

The SaxaVord Spaceport didn't actually identify the specific operator, stating simply that it was “one of SaxaVord’s clients.” However, it did provide enough detail to identify Rocket Factory Augsburg as the unnamed customer.

Additionally, in April, Rocket Factory Augsburg announced that it was working toward a launch window opening on July 1. However, the company stressed that “there are uncertainties, and the schedule may evolve.” Now, it seems, there is less uncertainty.

In the rocket size scale, I wouldn't be at all surprised if Starship could carry the RFA One vehicle without sweating.

China is making progress

Making progress in catching up with SpaceX - and Space 2.0 

China recovered their first orbital booster on an offshore drone ship

The nation has recovered a rocket during an orbital launch for the first time ever, pulling off the feat during the Long March 10B's maiden liftoff on Friday (July 10). And that recovery was unique: The rocket's first stage nestled softly into a net-like structure carried by a ship at sea.

"This mission marks my country's first successful controlled recovery of a launch vehicle and the world's first network-based recovery of a launch vehicle," the China Aerospace Science and Technology Corporation (CASC) announced via social media shortly after the launch. (Translation by Google.) "It signifies a historic breakthrough for my country in the field of reusable rocket technology and will lay a solid foundation for accelerating the improvement of my country's space access capabilities." 

We don't know much about the Long March 10B, other than that it's 63 meters tall (about 207 feet) and the first stage burns kerosene and liquid oxygen (LOX) propellants, the same as the Falcon 9's Merlin engines. Unlike the Falcon 9, which uses the same propellant for the upper stage, the Long March's second stage uses LOX and liquid methane.  

As we're talking about dealing with China, which means the CCP, there aren't many details available. They say the launch carried a satellite and it successfully achieved "its predetermined orbit," and I'll accept that since there are no claims otherwise. 

Image

I would like to know what that black smoke coming out of the top of the booster is, and if that's expected, though. 

Up until now, the Chinese launch sector has been working toward other booster landings and recoveries, but hasn't used any for missions like this. I consider this a probable success, and a major improvement. Don't forget we've seen documented situations of Chinese launches culminating in dropping the booster on populated areas. This one is nearly six years ago. 

Honestly, Booster reuse hasn't been as widely used around the industry as I expected it to be.  SpaceX is the obvious and clear leader. Yesterday's post on the 36th flight of B1062 posted that it was the 635th booster landing to date for SpaceX. New Glenn has had a couple of successful landings but hasn't reflown once - the booster that exploded on the launch pad at the end of May was going to be their first attempt. And New Glenn is the only other large vehicle that has attempted landing and reuse. Rocket Lab has landed some of their Electron boosters and done some reuse flights, but Electron lifts much smaller payloads than Falcon 9 does.

SpaceX has been a bit heavily guarding details on how much they save, but rumors go around that a flight they charge in the vicinity of $60 million for actually costs in the $10 to $15 million range.

Our old friend set another spaceflight record again, this morning

Friend is kind of a wrong concept for inanimate objects, but after writing stories about booster B1067 for over five  years, I've started to feel like it's an old friend. The kind of friend you know you can always count on when you need something. 

B1067 set a new record for SpaceX this morning, with its 5:25 AM EDT (0925 UTC) launch of Starlink 10-42 mission. The record launch is the 36th flight for B1067, and if it seems like its last record flight wasn't long ago, you're exactly right. The record 35th flight was June 8, 31 days ago. 

While completely different sized ships, requiring completely different levels of work to prepare for a flight, the highest number of flights of a reusable ship was NASA's Space Shuttle Discovery. Discovery flew 39 times, and the one month turnaround between flights seems to imply that someone at SpaceX is following that record and wants to ensure that B1067 becomes the world leader in number of flights. If that's the case, four flights sets the new record, which could be by the end of November. Four months from now.

B1067, began flying in June 2021 with the company’s 22nd Dragon flight as part of the Commercial Resupply Services-2 contract with NASA. It went onto fly the Crew-3 and Crew-4 missions as well as 24 batches of Starlink satellites.

A little more than eight minutes after liftoff, B1067 landed on the drone ship, ‘A Shortfall of Gravitas’, positioned in the Atlantic Ocean. This was the 160th landing for this vessel and the 635th booster landing to date for SpaceX.

Miami-based company launches a nuclear reactor on Transporter-17

During the talk about the Transporter-17 mission out of Vandenberg SFB yesterday, what was probably the most technically interesting payload on the Rideshare mission wasn't mentioned at all. 

The satellite from Miami-based City Labs is named BOHR, short for Betavoltaic Orbital High-Reliability, and it launched on a SpaceX rideshare mission Tuesday alongside 80 other payloads. SpaceX’s Falcon 9 rocket released the BOHR satellite into an orbit between 350 and 400 miles (nearly 600 km) in altitude. 

City Labs bills the BOHR mission as “the world’s first commercial nuclear-powered satellite and first nuclear CubeSat.” CubeSats are modest in scale, and images released by City Labs suggest BOHR is built on a “1U” CubeSat platform, a cubical design measuring about the same size as a softball. BOHR’s power source is a nuclear betavoltaic battery that generates electricity from the decay of tritium, a radioactive isotope of hydrogen.

It probably goes without saying that City Labs is rather proud of BOHR and talks it up by calling it “a historic step for commercial nuclear power in space” and  “BOHR demonstrates that safe, compact, and regulatory-approved nuclear power systems are ready for routine commercial deployment. This capability enables persistent, always-on payload operations that are not constrained by sunlight or battery life,” to quote Peter Cabauy, CEO of City Labs, in a statement. 

While this photo doesn't look to be as small as a softball, this the BOHR test cubesat system.

Image

This is a test mission for City Labs, who plan to use the experimental NanoTritium power generator in demonstration mode to supply electricity to a payload onboard the BOHR CubeSat. 

The spacecraft itself uses conventional solar power for regular operations, the company said. Betavoltaic batteries are best suited for low-power applications that require a reliable, long-duration source of electricity. These use cases include remote terrestrial sensors—such as in undersea or polar locations—and instrumentation for secure communications. City Labs is also studying the use of its NanoTritium technology to power implantable medical devices. 

Those of us who live near the Cape have seen protestors for anything that can be considered nuclear powered and the BOHR module went through all the tests to clear it for flight. It's important to point out that the company’s betavoltaic power systems are small—in the nanowatt to microwatt range—far short of the electricity required to power a smartphone, much less a large spacecraft or a Moon base. 

BOHR was the first commercial nuclear mission to pass through the Federal Aviation Administration’s new nuclear launch approval process. The FAA authorized City Labs to launch the BOHR mission last September.

[T]he BOHR satellite carries just a tiny amount of radioactive material, and the tritium isotope decays more quickly than plutonium or uranium. It’s also less toxic than other well-known nuclear fuels. “Tritium emits a weak form of radiation, a low-energy beta particle similar to an electron. The tritium radiation does not travel very far in air and cannot penetrate the skin,” the Nuclear Regulatory Commission says on its website.

The small amount of power the BOHR reactor can generate underlines the idea that this must be the first step in the development of flight-rated reactors that produce orders of magnitude more power than this one - millions to billions of times more power. How big those steps can be point toward how long it will be before reactors capable of generating usable numbers of watts can be used.

It's a Pathfinder for future reactor systems that will be tested and used in space.

Fire detectors, 3D printers and more on SpaceX rideshare mission

Early this morning, 12:12 AM PDT at Vandenberg Space Force Base, SpaceX launched one of their Transporter Rideshare missions into a sun-synchronous orbit (as Transporter launches tend to). This flight, labelled Transporter 17, carried 81 different payloads. The flight was carried by booster B1097 on it's 11th flight, so still an "almost new" booster, and landed on the "Of Course I Still Love You" droneship 8-1/2 minutes after liftoff. 

It's an interesting mix of payloads 

The Transporter-17 mission continued SpaceX’s model of launching dozens of satellites from companies around the world. Once again, the majority of the payloads hitching a ride on this Falcon 9 rocket were manifested by Exolaunch, which has placed satellites on every Transporter mission going back to the start of the Smallsat Rideshare Program in 2020.

On this flight, Exolaunch was responsible for 49 out of the 81 satellites, representing 20 international customers.

An interesting set of payloads was a trio of Earth Observing satellites for the Earth Fire Alliance, which aims to put up a constellation of fire monitoring satellites aimed at tracking wild fires and helping to control them. 

The Earth Fire Alliance stated on its website that it aims for a constellation of more than 20 satellites in low Earth orbit between 2027 and 2029, allowing it to have a roughly one hour revisit rate on wildfires with an ability to detect fires as small as five by five meters. It aims to ultimately have more than 50 satellites in orbit.

“This story is about living with fire: learning from it, adapting to it, harnessing it, and building resilience around it,” the nonprofit wrote in a LinkedIn post. “Inspired by a species of bird that has evolved alongside fire, our Black Kite Trio (BK-3) mission reflects Earth Fire Alliance’s vision of helping people, ecosystems, and communities confidently coexist with fire.”

This is the trio of satellites after being posed for a photograph between final test and loading onto the Transporter carrier.

Other Exolaunch-manifested payloads include four of Iceye’s synthetic aperture radar satellites, Bro-31, the first of Unseenlabs’ second-generation satellites designed for space-based radio detection; and Leonav-1, the United Arab Emirates first low Earth orbit PNT (position, navigation, and timing) satellite.

One that caught my eye is they put a 3D printer in orbit. 

Polish-German manufacturing company, Orbital Matter, also flew its Replicator-2 satellite on this mission. It focuses on the capability of 3D printing materials in the vacuum of space.

“It has 4 of our Printer Assisted Deployment Systems (P.A.D.S) onboard, 2 of which will be used to deploy our custom in-house designed foldable solar array. The other two will be standalone printers, one of which is deploying a secret antenna payload,” wrote Robert Ihnatisin, Orbital Matter CEO, on LinkedIn.

“The goal for this mission is to not only show that 3D printing is possible directly in the harsh space environment but also to show that it can be used for deployment right now! This is the latest in a string of missions focused on advancing our printing technology, with each mission getting us closer to the target of large scale and cheap solar power in orbit.”

'Acceleration without fuel' - revolutionary thruster aces first tests on orbit

News broke on Space.com this afternoon about successful tests of the first of its kind thruster that uses superconducting magnets to move a satellite in space. 

Zenno Astronautics, a spin-off from the University of Auckland, has flown its new "Supertorquer" system on the Mira satellite built by California-based start-up Impulse Space. The tests began shortly after Mira's launch in November last year aboard the SpaceX Transporter 12 mission and saw the shoebox-size device perform with flying colors, Zenno Astronautics CEO and founder Max Arshavsky, told Space.com.

Superconducting magnetics can convert solar energy input directly into momentum in space, by interacting with the Earth's magnetic field, so the solar energy input takes the place of liquid fuels carried for onboard thrusters. The problem with this approach has been that the hardware to do it was too big, complex, and heavy to fit on a satellite. 

"It's a technology that allows a spacecraft to not tumble violently in space and point in the right direction," Arshavsky said. "The unit has multiple super-conducting magnets that are positioned in different axes. When we power up the magnets, they generate a magnetic field, which interacts with Earth's magnetic field, and because we can control the magnetic field on the satellite, we can control the way in which it turns with respect to Earth."

Shoebox size? Like this? I'll guess that's about a foot along the horizontal axis and around 4" on the vertical. It wouldn't work on some really small satellites, but maybe that's not the target mission. For now.

Image

If you're familiar with any of the demonstrations of superconductivity like I've seen, you might be thinking, "doesn't that require super cold liquid to soak the wires in?" The wires have to be super, single digit-Kelvin temperatures, but liquids aren't required. Nor does it depend on the environment where it's operating (the satellite) be that cold. 

The unit housing the superconducting magnets is wrapped in layers of insulation and fitted with a heat pump that removes all the excess heat from the system. Every time the satellite needs a push, the superconducting coils power up, drawing energy from a battery charged by the satellite's solar panels. 

Superconducting magnetics are a potentially huge field, Arshavsky talks about using magnetics to make Earth to Mars missions more reasonable. The details there aren't clear to me, but I've never studied things like the solar magnetic field, that I know we live in and are affected by but without important details. CEO Arshavsky has been looking at other applications. 

"Once you have super-conducting technology available in space, you can then create very strong magnetic fields and you can use them for various use cases," he said. "You can accelerate things in space very fast or change the trajectory of a satellite completely without fuel."
...
Powerful superconducting magnets could also provide a solution to the problem of cancer-causing cosmic radiation that explorers will encounter during stays on the moon or trips deeper into space.

"When we go to space, we get hurt by radiation, and these superconducting magnets can create umbrellas of magnetic fields around the spacecraft to protect the interior," said Arshavsky. "So we can shield people in space from that radiation."

Zenno Astronautics company plans to fly a larger demonstrator on an undisclosed mission later this year.

Yeah, he's a CEO, so I automatically figure that some percentage is too wishful and it's not all easy or maybe not even doable at all, but it's some pretty interesting stuff.

Headlines that caught my eye

Some serious stories, others just because they're odd headlines  

First, something we talked about several times, "NASA launches rescue mission to save Swift space telescope from burning up in Earth's atmosphere." 

The Swift Boost mission successfully launched the LINK satellite, built by Arizona-based Katalyst Space Technologies, on Friday (July 3) at 4:36 a.m. EDT (0836 GMT), according to NASA. LINK will rendezvous with NASA's Neil Gehrels Swift Observatory and tow it to a stable orbit, saving it from impending destruction as its trajectory dips farther into the atmosphere. 

The LINK spacecraft is on its way toward the Swift Observatory satellite, and once close enough to the Swift, LINK will spend two to three weeks performing observations of Swift to assess optimal grapple points on the observatory. They say there aren't enough good images of the satellite to plan how to grab it and lift it to a safer orbit. 

Next, how does spaceflight relate to the semiquincentennial? 

There was clearly no spaceflight at the start of the Republic. There was no flight of any kind.

In November 1783, a bit over 7 years after July of 1776, a hot-air balloon designed by the Montgolfier brothers carried two men on a 25-minute flight over Paris, beginning the age of flight and leading to all sorts of speculation about better types of flight to come. 

It was 120 years later before the Wright Brothers first flight on the beaches of North Carolina in 1903. It took less than half that 120 year gap before the first manned spaceflight took place. Soviet cosmonaut Yuri Gagarin took that ride for the first time on April 12, 1961. Comparatively it's nothing short of amazing that eight years later, Apollo 11 astronauts Neil Armstrong and Buzz Aldrin landed on the moon. Let's see... 120 years... 58 years... 8 years? That's an incredible pace of advancement. 

Let me ask a question that may not go over well. 

Have you ever wanted to observe Uranus? 

The planet! Not that. This is a little late, but the headline stands on its own. "Want to see Uranus? July 4 could be your best chance in decades"

Although we often hear that only five planets are visible to the unaided eye, Uranus can also be seen from Earth under the right conditions. As the seventh planet from the sun, it is very faint — near the threshold of naked-eye visibility at roughly sixth magnitude — so viewing it requires a very dark sky with little to no significant light pollution.

The article on Space.com includes several little images to help guide you to the planet, which will only be visible to your naked eye if you live in a place with good, dark skies, and the fact that this should have been a story for Saturday morning means their guides won't be quite right. A planetarium program or the Stellarium web page could get you there. 

Finally, a story that blew my mind in disbelief the first time I skimmed it.  

A Semiconductor manufacturing test bed flew on the booster for today's Starlink satellite/Falcon 9 launch

If it flew with the Starlink satellites, I would have been much less confused, but when it became apparent they really meant on the booster I realized they were talking about an eight minute test - maybe a few seconds longer or shorter.  

Two semiconductor fabrication test beds hitched a sub-orbital ride on the first stage of a SpaceX Falcon 9 rocket that launched another batch of Starlink satellites from Cape Canaveral shortly after sunrise Sunday. 

In addition to boosting 29 satellites for SpaceX’s internet service, the Falcon 9 first-stage booster carried two manufacturing pods for Washington, D.C.-based startup Besxar Space Industries on an eight-minute, 19-second ride to space and back.

If you're used to watching these Falcon 9 launch videos, you'll recall that the booster continues upward after stage separation, typically well beyond the Karman line at 100km, the recognized border of space, and reach a peak altitude of around 120 km.

Besxar says these short-duration, sub-orbital flights with their rapid turnarounds are ideal for fine-tuning its manufacturing process. The test-bed Fabships, called the ‘Clipper Class’, are about the size of a microwave oven.

“With a regular cadence of launch and reentry missions, we can now iterate faster than ever—transforming space into a critical extension of America’s semiconductor supply chain,” said Pilipiszyn, who previously worked for OpenAI in its early days.

Like the others, this one has more details to make reading it more worthwhile.

Happy Independence Day - 2026

I've run this post almost every July 4th in the 16 years I've been blogging.  There were only two years I didn't and both of those posts were about problems that must have seemed really big. They not only were really big but still are (20122014).  My lesson is that while they were important, the big picture is to remind ourselves of the history, and celebrate the achievement of getting to our semiquincentennial, the 250th anniversary of our Republic, while we enjoy the day with family and friends.  The problems will still be here on the fifth. 


IN CONGRESS, JULY 4, 1776

The Unanimous Declaration of the Thirteen United States of America

When, in the course of human events, it becomes necessary for one people to dissolve the political bands which have connected them with another, and to assume among the powers of the earth, the separate and equal station to which the laws of nature and of nature's God entitle them, a decent respect to the opinions of mankind requires that they should declare the causes which impel them to the separation.  

We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable rights, that among these are life, liberty and the pursuit of happiness. That to secure these rights, governments are instituted among men, deriving their just powers from the consent of the governed. That whenever any form of government becomes destructive to these ends, it is the right of the people to alter or to abolish it, and to institute new government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their safety and happiness. Prudence, indeed, will dictate that governments long established should not be changed for light and transient causes; and accordingly all experience hath shown that mankind are more disposed to suffer, while evils are sufferable, than to right themselves by abolishing the forms to which they are accustomed. But when a long train of abuses and usurpations, pursuing invariably the same object evinces a design to reduce them under absolute despotism, it is their right, it is their duty, to throw off such government, and to provide new guards for their future security. --Such has been the patient sufferance of these colonies; and such is now the necessity which constrains them to alter their former systems of government. The history of the present King of Great Britain is a history of repeated injuries and usurpations, all having in direct object the establishment of an absolute tyranny over these states. To prove this, let facts be submitted to a candid world. 

He has refused his assent to laws, the most wholesome and necessary for the public good.

He has forbidden his governors to pass laws of immediate and pressing importance, unless suspended in their operation till his assent should be obtained; and when so suspended, he has utterly neglected to attend to them. 

He has refused to pass other laws for the accommodation of large districts of people, unless those people would relinquish the right of representation in the legislature, a right inestimable to them and formidable to tyrants only. 

He has called together legislative bodies at places unusual, uncomfortable, and distant from the depository of their public records, for the sole purpose of fatiguing them into compliance with his measures. 

He has dissolved representative houses repeatedly, for opposing with manly firmness his invasions on the rights of the people. 

He has refused for a long time, after such dissolutions, to cause others to be elected; whereby the legislative powers, incapable of annihilation, have returned to the people at large for their exercise; the state remaining in the meantime exposed to all the dangers of invasion from without, and convulsions within. 

He has endeavored to prevent the population of these states; for that purpose obstructing the laws for naturalization of foreigners; refusing to pass others to encourage their migration hither, and raising the conditions of new appropriations of lands. 

He has obstructed the administration of justice, by refusing his assent to laws for establishing judiciary powers. 

He has made judges dependent on his will alone, for the tenure of their offices, and the amount and payment of their salaries. 

He has erected a multitude of new offices, and sent hither swarms of officers to harass our people, and eat out their substance. 

He has kept among us, in times of peace, standing armies without the consent of our legislature. 

He has affected to render the military independent of and superior to civil power.

He has combined with others to subject us to a jurisdiction foreign to our constitution, and unacknowledged by our laws; giving his assent to their acts of pretended legislation: 

For quartering large bodies of armed troops among us: 

For protecting them, by mock trial, from punishment for any murders which they should commit on the inhabitants of these states: 

For cutting off our trade with all parts of the world: 

For imposing taxes on us without our consent: 

For depriving us in many cases, of the benefits of trial by jury: 

For transporting us beyond seas to be tried for pretended offenses: 

For abolishing the free system of English laws in a neighboring province, establishing therein an arbitrary government, and enlarging its boundaries so as to render it at once an example and fit instrument for introducing the same absolute rule in these colonies: 

For taking away our charters, abolishing our most valuable laws, and altering fundamentally the forms of our governments: 

For suspending our own legislatures, and declaring themselves invested with power to legislate for us in all cases whatsoever. 

He has abdicated government here, by declaring us out of his protection and waging war against us. 

He has plundered our seas, ravaged our coasts, burned our towns, and destroyed the lives of our people. 

He is at this time transporting large armies of foreign mercenaries to complete the works of death, desolation and tyranny, already begun with circumstances of cruelty and perfidy scarcely paralleled in the most barbarous ages, and totally unworthy the head of a civilized nation. 

He has constrained our fellow citizens taken captive on the high seas to bear arms against their country, to become the executioners of their friends and brethren, or to fall themselves by their hands. 

He has excited domestic insurrections amongst us, and has endeavored to bring on the inhabitants of our frontiers, the merciless Indian savages, whose known rule of warfare, is undistinguished destruction of all ages, sexes and conditions. 

In every stage of these oppressions we have petitioned for redress in the most humble terms: our repeated petitions have been answered only by repeated injury. A prince, whose character is thus marked by every act which may define a tyrant, is unfit to be the ruler of a free people.  

Nor have we been wanting in attention to our British brethren. We have warned them from time to time of attempts by their legislature to extend an unwarrantable jurisdiction over us. We have reminded them of the circumstances of our emigration and settlement here. We have appealed to their native justice and magnanimity, and we have conjured them by the ties of our common kindred to disavow these usurpations, which, would inevitably interrupt our connections and correspondence. They too have been deaf to the voice of justice and of consanguinity. We must, therefore, acquiesce in the necessity, which denounces our separation, and hold them, as we hold the rest of mankind, enemies in war, in peace friends. 

We, therefore, the representatives of the United States of America, in General Congress, assembled, appealing to the Supreme Judge of the world for the rectitude of our intentions, do, in the name, and by the authority of the good people of these colonies, solemnly publish and declare, that these united colonies are, and of right ought to be free and independent states; that they are absolved from all allegiance to the British Crown, and that all political connection between them and the state of Great Britain, is and ought to be totally dissolved; and that as free and independent states, they have full power to levy war, conclude peace, contract alliances, establish commerce, and to do all other acts and things which independent states may of right do. And for the support of this declaration, with a firm reliance on the protection of Divine Providence, we mutually pledge to each other our lives, our fortunes and our sacred honor. 

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 

It has been shown mathematically that in a system with multiple parties, they either converge to two declared parties or through something like a coalition system they functionally become a two party system. In our society, we are too broken apart along party lines, despite the idea of one big “uniparty” now being the subject of millions of jokes and other comments. In reality, the important choice is a question of whether or not the politico you're referring to is a follower of our founding documents or someone else's. Right now, it appears the biggest competing idea is a tyrannical minority in the name of some form equality, equity or some such nonsense. The biggest competitor is Karl Marx. People are not, and cannot be both free and equal. We are either free or forced into subjugation to create equal outcomes. Opportunities can be equal, like that word that used to be a goal but is now punishable: colorblind. Outcomes can't be. 

Enjoy your day no matter what you do. To those who serve - and have served - to provide this gift of liberty for us:  Thank You from the bottom of my heart.

The Last Atlas V Leo Launch

This morning's Atlas V launch was labelled by the local newspaper as, "Atlas V rocket's final satellite mission...". Which is mostly true at one level, but it's not the last Atlas V launch and not their last launch of any satellite whatsoever. 

Say what? 

The version of the Atlas V that launched today was the Atlas V 551, where 551 means it had five strap-on solid rocket boosters, a 5 meter wide payload fairing and a Centaur upper stage with one engine. The payload was 29 Amazon LEO satellites, so while it's the last launch of LEO satellites for Amazon, that doesn't mean they can't launch other satellites into a Low Earth Orbit.

Here's the tricky part. 

Following Thursday’s launch there will be just six Atlas 5 rockets remaining. All of those are reserved to fly Boeing’s CST-100 Starliner spacecraft. 

Will there really be six Starliner flights? Good question. I don't think I'd put much faith in that, but we'll find out. We just know they won't be flying the 551 version for Starliners. 

Those rockets fly in the N22 configuration and are the only variant of an Atlas 5 rocket that feature a dual-engine Centaur upper stage. After the 2024 Crew Flight Test of Starliner in 2024 experienced several issues resulting in NASA declaring a Type A mishap, the cargo-only Starliner-1 launch date is in question. 

The Atlas V has put 224 Amazon LEO satellites in orbit, and they have bought three launches each from Arianespace on their Ariane 6, and SpaceX, on their Falcon 9. They've also contracted for 38 launches using ULA’s Vulcan rocket and 27 launches with Blue Origin’s New Glenn rocket. Their problem is that both of those launch vehicles are grounded due to anomaly investigations, and Blue Origin is also slowed down by reconstruction of their SLC-36 structure after the late May explosion of the New Glenn on the pad.

While it's impossible to give a date for a New Glenn launch, the Vulcan launch is targeted for "sometime in the third quarter of 2026." Technically speaking, that's now, but I expect closer to the end of the quarter. Except, it's being reported that ULA stacked its Vulcan rocket inside its new VIF-A hangar and plans to conduct a wet dress rehearsal tanking test following this morning's launch.

It's time to start asking some bigger questions about Starliner

The foundational question isn't really when it will fly a crewed mission. The bigger question is whether Starliner can ever get to fly as well and safely as it was sold. The ISS is in the last years of its life and Starliner is running out of time to get re-designed or fixed.

Word broke today that NASA's office of the Inspector General (OIG) released an audit of the vehicle Tuesday saying that it's looking likely that Starliner won't be certified for operational flights to the International Space Station until next year. 

The irony here is that Starliner was first expected to fly in 2017. Yeah, 10 years late. Boeing started working on Starliner years before that. 

While the story is covered by both Ars Technica (that link just above) and Space dot com, I'll say here that Space.com might be a better stop, primarily because at the top of their article, they have a full video, nine minutes long, of a talk Administrator Isaacman gave that's good listening. I expect that most readers here are probably fairly familiar with the story of how bad Starliner's Crewed Flight Test went in 2024. Pages have been posted here about it, and this set of search results can re-familiarize you with the story, if needed. Or you can listen to Isaacman's talk hosted at Space.com

Interestingly and as expected, Isaacman wasn't remotely afraid to place blame for things NASA did wrong, not just what Boeing did. Writing about the OIG, Space.com author Elizabeth Howell noted:

The authors added that underperformance on CFT can be traced to NASA's overconfidence in the spacecraft design, "unrealistic launch and flight test schedules" made by Boeing and accepted by NASA, and "pressure to adhere to this aggressive schedule." And these issues were compounded by NASA not exercising "data rights," which would have let the agency look at "flight-simulation-training failures" that likely would have helped with crew safety ahead of launch. 

Before it gets too forgotten, people need to remember that when the Commercial Crew Program was starting in 2014, Boeing got this contract and SpaceX didn't. Everyone expected that the safe bet was Boeing. They had the name, decades of experience contracting to NASA, while SpaceX was an unknown. SpaceX had yet to achieve their first successful booster landing and were just getting started in launching for others. That they would completely beat Boeing, so completely that the Starliner Crew of Butch Wilmore and Sunni Williams had to ride a SpaceX Dragon capsule back down and it had become so commonplace that nobody thought about not sending the Dragon for them. 

It's not that SpaceX didn't have their own problems, they just solved them years ago - their first booster landing was on December 21, 2015. 

NASA concurred with all of OIG's recommendations to the agency going forward, which are:

  • Delay payments to Boeing until Starliner's human-rating certification completes;
  • Create a schedule with Boeing for the next Starliner flights;
  • Document and resolve all of the CFT issues in "NASA's mishap information system" and update the schedule for Starliner with these issues in mind;
  • Make private company flight-simulation testing on hardware and software changes accessible to NASA;
  • Make NASA's mishap-classification requirements more clear;
  • Prioritize NASA hiring efforts to focus on "critical skillsets" related to commercial crew and to the expected decommissioning of the ISS.
