This is what 99%+ combustion efficiency looks like for LOX/Kerosene. Thanks to LOX cooling, E-2 doesn't require chamber film cooling. Paired with a highly efficient injector, combustion efficiency and specific impulse are maximized, boosting payload capacity and unlocking

Who has ever seen a LOX/Kerosene liquid 🚀 engine with a blue plume 💎💎💎💎? Not only does it look spectacular, but it also serves as undeniable proof of the 99%+ combustion efficiency achieved in this test. Enjoy this 3-minute, 20-second test of E-2, a mostly 3D-printed 22k

The Launcher team just witnessed our first spacecraft, Orbiter SN1, launch to orbit on a Falcon 9 rocket! We are so grateful for the opportunity to fly on SpaceX’s Transporter-6 rideshare mission and thankful for our first customers on Orbiter. Separation coming up next! 🙏🚀🛰️

Introducing Launcher Orbiter - the first orbital transfer vehicle compatible with both SpaceX Falcon 9 rideshare and a dedicated small launch vehicle (Launcher Light). Orbiter is contracted with @spacex to Fly to Sun-Synchronous Orbit in October 2022. launcherspace.com/orbiter

Launcher E-2 3D printed 🚀 engine photos by @johnkrausphotos from today’s performance boost testing. Efficiency increase in action to the point the plume is transparent. We continue to push today with 2-3 more tests at higher mixture ratio.

The first fully integrated E-2 engine is ready for shipping to @NASAStennis for our upcoming full engine test campaign later this year. E-2 is a 22,000 lbf (10 tf) thrust LOX/Kerosene oxidizer-rich, staged combustion engine. Stay tuned for updates.

At our Mojave, CA test site, E-2 ran at boosted thrust for a 1-minute duration, achieving 25,000 lbf thrust and measured 295 seconds Isp. Although E-2 is a kerosene/LOX engine, its plume is blue and transparent, demonstrating its 99%+ combustion efficiency. E-2 is now available

🚀 Our team at @NASAStennis is making great progress on the development of our E-2 engine for Launcher Light. This is the second test of our new coax swirl injector in 250 fps slow motion (successful 2 sec ‘burp’). More to come soon.
