NASA’s massive Space Launch System rocket crept toward its Florida launch pad today at a top speed of about 1 mph, marking the first step in a journey that will eventually send astronauts around the moon for the first time in more than 50 years.

The 4-mile trek to Launch Complex 39B at NASA’s Kennedy Space Center began at 7 a.m. ET (4 a.m. PT) and lasted until evening. Because the rocket with its mobile launcher stands more than 300 feet tall and weighs millions of pounds, the trip required the use of a crawler-transporter — the same vehicle used for the Apollo and space shuttle programs, now upgraded for NASA’s Artemis moon program.

Liftoff for the Artemis 2 mission could come as early as Feb. 6, but there’s lots to be done in the weeks ahead. After today’s rollout, the mission team will conduct a thorough checkout of the Space Launch System and its Orion crew spacecraft. Then there’ll be a “wet dress rehearsal,” during which the launch team will fuel the rocket and count down to T-minus 29 seconds.

“We have, I think, zero intention of communicating an actual launch date until we get through wet dress,” NASA Administrator Jared Isaacman told reporters.

Artemis 2 is slated to send three NASA astronauts and one Canadian astronaut on a 10-day journey tracing a figure-8 route around the moon. The trip will take them as far as 4,800 miles beyond the lunar far side — farther out than any human has gone before.

A decades-old rocket factory in Redmond, Wash., is due to be rebranded with a time-honored name: Rocketdyne.

If all goes according to plan, the facility will become part of a joint venture created under the terms of an $845 million deal involving L3Harris Technologies and AE Industrial Partners.

L3Harris took over the Redmond facility in 2023 when it acquired Aerojet Rocketdyne for $4.7 billion. Now L3Harris plans to sell a majority stake in its Space Propulsion and Power Systems business to AE Industrial, while retaining 40% ownership of the newly created Rocketdyne venture. The transaction is expected to close in the second half of 2026, subject to regulatory approvals and other conditions.

A space startup founded by veterans of Jeff Bezos’ Blue Origin space venture is recruiting partners in its quest to build robotic arms powered by artificial intelligence.

Founded in late 2024, Puyallup, Wash.-based Orbital Robotics is still in its infancy — but it has already raised about $310,000 in funding. Orbital Robotics CEO Aaron Borger told GeekWire that the company is working with a stealthy space venture on an orbital rendezvous project for the U.S. Space Force, with a series of demonstration missions scheduled in the next year and a half.

And that’s just the start: Borger and his teammates are trying to get traction for a plan that could give NASA’s aging Hubble Space Telescope a much-needed boost.

Astronomers say they’ve found an asteroid that spins faster than other space rocks of its size.

The asteroid, known as 2025 MN45, is nearly half a mile (710 meters) in diameter and makes a full rotation every 1.88 minutes, based on an analysis of data from the Vera C. Rubin Observatory. “This is now the fastest-spinning asteroid that we know of, larger than 500 meters,” University of Washington astronomer Sarah Greenstreet said today at the American Astronomical Society’s winter meeting in Phoenix.

Greenstreet, who serves as an assistant astronomer at the National Science Foundation’s NOIRLab and heads the Rubin Observatory’s working group for near-Earth objects and interstellar objects, is the lead author of a paper in The Astrophysical Journal Letters that describes the discovery and its implications. It’s the first peer-reviewed paper based on data from Rubin’s LSST Camera in Chile.

2025 MN45 is one of more than 2,100 solar system objects that were detected during the observatory’s commissioning phase. Over time, the LSST Camera tracked variations in the light reflected by those objects. Greenstreet and her colleagues analyzed those variations to determine the size, distance, composition and rate of rotation for 76 asteroids, all but one of which are in the main asteroid belt between the orbits of Mars and Jupiter. (The other asteroid is a near-Earth object.)

The team found 16 “super-fast rotators” spinning at rates ranging between 13 minutes and 2.2 hours per revolution — plus three “ultra-fast rotators,” including 2025 MN45, that make a full revolution in less than five minutes.

Year in Space: Get ready for magnificent moon missions

Lunar missions once felt like the domain of history books rather than current events, but an upcoming trip around the moon is poised to generate headlines at a level not seen since the Apollo era.

NASA’s Artemis 2 mission, which is due to launch four astronauts on a round-the-moon journey as a warmup for a future lunar landing, is shaping up as the spaceflight highlight of 2026. NASA Administrator Jared Isaacman, who took the agency’s helm this month after a tumultuous year, says it’s the top item on his must-see list.

“What’s not to be excited about?” he said last week on CNBC. “We’re sending American astronauts around the moon. It’s the first time we’ve done that in a half-century. … We’re weeks away, potentially a month or two away at most from sending American astronauts around the moon again.”

The Pacific Northwest plays a significant role in the back-to-moon campaign. For example, L3Harris Technologies’ team in Redmond, Wash., built thrusters for Artemis 2’s Orion crew vehicle. And Artemis 2 isn’t the only upcoming moon mission with Seattle-area connections: Jeff Bezos’ Blue Origin space venture, headquartered in Kent, plans to send an uncrewed Blue Moon Mark 1 lander to the lunar surface in 2026 to help NASA get set for future moon trips.

“We are taking our first steps to help open up the lunar frontier for all of humanity,” Paul Brower, Blue Origin’s director of lunar operations, said in a recent LinkedIn post.

Eleven years after United Launch Alliance CEO Tory Bruno partnered with Blue Origin to create a new rocket engine, he’s joining Jeff Bezos’ space venture as the president of Blue Origin’s newly created National Security Group.

The move could signal a major shift in the commercial space race as Kent, Wash.-based Blue Origin revs up its competition with SpaceX. Bezos welcomed Bruno to his company on social media, and Bruno told Bezos that “we are going to do important work together.”

NASA Administrator Jared Isaacman added his congratulations via the X social-media platform.

In its Dec. 26 announcement of the change, Blue Origin said Bruno would report to CEO Dave Limp. “We share a deep belief in supporting our nation with the best technology we can build,” Limp said in a post on X. “Tory brings unmatched experience, and I’m confident he’ll accelerate our ability to deliver on that mission.”

Bruno, 64, led ULA for 11 years following a 30-year career at Lockheed Martin. Not long after taking the reins at ULA in 2014, Bruno sat beside Bezos to announce a close collaboration on the development of Blue Origin’s BE-4 engine, which is used on ULA’s Vulcan rocket as well as Blue Origin’s orbital-class New Glenn rocket.

Since then, SpaceX has displaced United Launch Alliance as America’s dominant launch company. In 2014, ULA executed 14 launches while SpaceX executed six. So far this year, SpaceX has registered 165 launches, while ULA has registered six.

Starcloud plans its next power moves for AI in space

After taking one small but historic step for space-based AI, a Seattle-area startup called Starcloud is gearing up for a giant leap into what could be a multibillion-dollar business.

The business model doesn’t require Starcloud to manage how the data for artificial intelligence applications is processed. Instead, Starcloud provides a data-center “box” — a solar-powered satellite equipped with the hardware for cooling and communication — while its partners provide and operate the data processing chips inside the box.

Starcloud CEO Philip Johnston said his company has already worked out a contract along those lines with Denver-based Crusoe Cloud, a strategic partner.

“In the long term, you can think of this more like an energy provider,” he told GeekWire. “We tell Crusoe, ‘We have this box that has power, cooling and connectivity, and you can do whatever you want with that. You can put whatever chip architecture you want in there, and anything else.’ That means we don’t have to pay for the chips. And by far the most expensive part of all this, by the way, is the chips. Much more expensive than the satellite.”

If the arrangement works out the way Johnston envisions, providing utilities in space could be lucrative. He laid out an ambitious roadmap: “The contract is 10 gigawatts of power from 2032 for five years, at 3 cents per kilowatt-hour. That comes to $13.1 billion worth of energy.”

Jeff Bezos’ Blue Origin space venture added a page to the space history books today by sending the first wheelchair user into space.

“It was the coolest experience,” said Michaela “Michi” Benthaus, a German-born aerospace and mechatronics engineer at the European Space Agency who sustained a spinal cord injury in a mountain biking accident in 2018.

Blue Origin’s suborbital New Shepard rocket ship lifted off from the company’s Launch Site One in West Texas at 8:15 a.m. CT (6:15 a.m. PT). An initial launch attempt had been called off on Dec. 18 because the flight team “observed an issue with our built-in checks prior to flight,” Blue Origin said. It didn’t provide further details about the issue, but today’s countdown went off without a hitch.

This was the 37th New Shepard mission, and the 16th to carry humans on a brief ride above the 100-kilometer (62-mile) altitude level that marks the internationally accepted boundary of space. Eighty-six people, including Bezos himself, have now flown on New Shepard. Six have gone multiple times.

Microsoft and NASA say they’re applying artificial intelligence to a challenge that has become increasingly urgent: how to cope with flooding and other disasters driven by extreme weather.

The result of their efforts is Hydrology Copilot, a set of AI agents aimed at making hydrological data easier to access and analyze. The platform is built on the foundation that was established for NASA Earth Copilot, a cloud-based AI tool that can sift through petabytes of Earth science data.

Hydrology is the scientific study of Earth’s water cycle, which encompasses precipitation, runoff, evaporation and the movement of water through rivers, lakes and soil. It’s not just an academic exercise: Hydrologic insights are put to use in fields ranging from agriculture to forestry to urban development.

“NASA has long produced advanced hydrology and land-surface datasets, powering breakthroughs in drought early-warning systems, environmental planning and environmental research,” Juan Carlos López, a senior solution specialist at Microsoft who focuses on space and AI, wrote in a blog post. “Yet despite their value, these datasets and the specialized tools required to navigate and interpret them remain difficult to access for many who could benefit most.”

That’s where Hydrology Copilot comes in: Powered by Microsoft Azure OpenAI Service and Microsoft Foundry, the platform lets researchers query NASA’s data using straightforward questions — for example, “Which regions may be facing elevated flood risk?”

Scientists revise view of Titan — and hold out hope for life

A fresh analysis of tidal perturbations on Titan challenges a long-held hypothesis: that the cloud-shrouded Saturnian moon harbors an ocean of liquid water beneath its surface ice. But the scientists behind the analysis don’t rule out the possibility that smaller pockets of subsurface water could nevertheless provide a home for extraterrestrial life.

“The search for extraterrestrial environments is fundamentally a search for habitats where liquid water coexists with sustained sources of energy (chemical, sunlight, etc.) over geological time scales. Our new results do not preclude the existence of such environments within Titan, but rather, further support their plausibility,” University of Washington planetary scientist Baptiste Journaux, a co-author of the study published in Nature, told me in an email.

Journaux acknowledged that the results don’t match up with conventional wisdom. He said they represent a “true paradigm shift” in how scientists think Titan is put together.
