First (autonomous) flight soon, once I figure out why my ESC keeps cutting out. I pulled it from a 2nd hand heli I got as spares, cant seem to find the instructions anywhere, cheap rip off of something probably...

／ エンジンCOSMOS メタンエンジンで国内最大推力13トンを達成🚀 ＼ 北海道大樹町にある自社の試験場では、現在週1回のペースでZEROのエンジンCOSMOSの統合燃焼試験を実施しています。 今回の試験シリーズでは、推力13トンを記録し、エンジンの心臓部であるターボポンプも目標回転数に到達。国内で開発されたメタンエンジンとして、最大の推力を達成するという大きなマイルストーンを迎えました。 燃料には、十勝地域の家畜の糞尿から生産された液化バイオメタンを使用しています。エネルギーの地産地消や環境への配慮、そして地域とともに宇宙を目指すISTの「地域連携」を象徴する取り組みです。 本試験に対し、いつも多大なるご理解・ご協力をいただいている大樹町および地域の皆様に、心より感謝いたします。 #インターステラテクノロジズ #北海道 #大樹町 #InterstellarTechnologies #ZERO #Space #Rocket #Taiki #Hokkaido #Universe

@kegrocket Congrats! Things are going to get fun now!

Extremely successful cryo/tanking test for KegRocket. Next Stop: Static Fire

ULA is burning through its remaining Atlas V inventory with Vulcan effectively grounded. There are three Atlas Vs left for Amazon Leo, including this one. Still, a remarkably fast one-week turnaround from launch to stacking. ULA is going for a record-breaking 23-day turnaround at SLC-41 with this mission.

Book 5 of 2026 complete. Quite the eye opener, given the state of the world at the moment. I hope things get better for my daughters sake.

I know its VERY boring, but instead of making up a load of stuff about why I wanted German engines to have been inverted, from reading other things written by people who also didnt know, I just went and read the German report by Wolfram Eisenlohr who was in charge of German aero engine development for most of WW2 and who had been in the German Air Ministry a decade before when the layout was discussed - then translated it for you on video. Its my amateurs approach to history if you will.

"Never Tell Me The Odds" is back. Team Blue inspected every system, completed refurbishment, and certified it for flight. Proud to put a flight-proven booster to work for @AST_SpaceMobile on NG-3. Enjoy this fun video of us moving the integrated vehicle to the Transporter Erector (TE).

Piloted Thrustborne Transition. Watch it in its full glory. To the skies.

The first E-2 Block 1 engine integration is complete, and our team is now preparing for test fire. This design upgrade reduces mass, simplifies manufacturing, consolidates vehicle interfaces, and incorporates thrust vector control.  More updates to come as we progress through the test campaign! Propellants: LOX/Kerosene Thrust: 23k lbf (10.4 tf) Isp Sea Level: 290 s Isp Vacuum: 327 s Isp Vac Version: 365 s Cycle: Ox-Rich Staged Combustion

Artemis II astronauts are doing great. The Orion spacecraft is performing well in an impressive elliptical orbit, and the @NASA_Johnson Mission Control team is taking good care of the crew. Meanwhile, back at @NASAKennedy, the teams are out at the pad getting ready for what comes next. We are going to get into a rhythm of launching Moon rockets around here 🇺🇸

I just looked up at the moon as I put the rubbish out tonight, it suddenly dawned on me that in a few days there will be 4 people flying around it. How wild is that!

One of our Zenith engines fitted into the stage 1 aft module... things are starting to come together. 🚀🔧

Book 4 of 2026 complete. I liked this, easy read, abit of NZ, brought back lots of memories.

Wiring just about done. Like making a CAD drawing, it takes way longer than expected!

.@Nord_Space youtu.be/8AoKRQiyyAs?is…

Turbopump update! 90% of the parts are done, and the test stand is coming along. The turbine outlet duct finished machining marking the last large part to be made. Side quests included a dynamic balancing machine, and finally getting my custom ADC working.

INNOSPACE has identified the cause of the mission termination of its first commercial HANBIT-Nano launch through a joint investigation with Brazil’s aerospace accident investigation authority, CENIPA. The cause was determined through analysis of flight data, video records, and more than 300 recovered debris pieces. Approximately 33 seconds after liftoff, gas leakage occurred at the forward section of the first-stage hybrid rocket combustion chamber assembly, leading to a rupture of the combustion chamber. The investigation found that the leakage was caused by insufficient compression of sealing components during the on-site reassembly of the forward chamber plug as part of launch preparation activities in Brazil. INNOSPACE is strengthening its assembly processes and quality management procedures while implementing component improvements and additional verification. Following launch authorization from the Korea Aerospace Administration(KASA), the company plans to conduct a follow-up launch in Brazil in the third quarter of 2026. Based on the technical findings from this investigation, INNOSPACE will continue to enhance the reliability of its launch vehicles and improve mission success rates. ✨ 🔗 Learn more: bit.ly/4bdlkwS #NewSpace #SpaceLaunch #LaunchVehicle #RocketEngineering #SpaceTechnology #SpaceIndustry #SPACEWARD

Book 3 of 2026 complete. Surprised at how good it was, between the actual build pieces is a complete history of Supermarine and the Spitfire. Well put together and worth a read.
