Congratulations to the @VenusAerospace team - Venus has the world's only flight-proven high-thrust RDRE, and this capital will move them from flight demonstration toward deployment in defense and space applications!
Today, Venus Aerospace made history.
We completed the first-ever U.S. flight of a rotating detonation rocket engine — proving runway-based high-speed flight is possible.
A huge thanks to our team, @Spaceport_NM, our investors, and U.S. government partners.
Let’s keep moving faster.

My previous spaceflights involved multiple debris avoidance maneuvers. These pre-determined maneuvers adjust the orbit of the ISS to increase separation from tracked objects posing collision risks. With more traffic and activity than ever before, space debris continues to create a growing risk. We must treat this challenge with the same seriousness we apply to launch and reentry safety. The technology to address this problem exists, but we need the global framework and collective discipline to implement it. The choices we make today regarding orbital debris management will determine whether low Earth orbit remains a safe and accessible domain for generations to come.

It's an honor to join the @GilmourSpace board! Onward and upward!
Former NASA Deputy Administrator @Astro_Pam✨ joins the Gilmour Space Board.
Her experience will be invaluable as we continue building Australia's launch and satellite capabilities for our regional and international customers.
Welcome aboard, Pam! 🚀🛰️gspace.com/post/former-nasa-…
This is indeed welcome. CLD companies and their investors have invested a lot of money and made tremendous progress. Commercial Cargo and Crew took time too.
In the spirit of learning from past programmatic challenges and ensuring a responsible transition from the International Space Station, NASA evaluated both the current commercial space station approach and alternative pathways.
Industry has provided extensive feedback making the case for a sustainable commercial market in which NASA is one customer among many, along with assurances regarding available transportation capabilities. The industry position will now shape the path forward as NASA proceeds with the original commercial strategy.
Over the coming weeks, NASA will work with stakeholders and industry to refine flexible requirements and acquisition plans, with a draft RFP expected later this month.

I am so proud of the Artemis II crew and the thousands of people at NASA and their industry and international partners who made the mission a success!
This choked me up. We miss you Jim!
"Welcome to my old neighborhood." Our @NASAArtemis II astronauts woke up on the sixth day of their mission to a special message recorded in 2025 by astronaut Jim Lovell, the pilot of Apollo 8.

🚀 Former astronauts @Astro_Pam & @Astro_SEAL on the historic mission:
Melroy: “An incredibly exciting moment… the first step toward a moon base.”
Cassidy: “They’re on cloud nine.”
A new era of space exploration.

Space debris is a growing problem and the danger goes beyond direct hits. During a spacewalk you can see just how many times the Space Station has been hit by debris, which is especially problematic on the handrails. Spacewalkers are told to avoid touching any handrail that has visibly been struck because the uneven surface could easily tear a hole in your glove - creating a very serious situation. The threat of space debris is something we all agree on, but have yet figured out how to truly solve.
Looking forward to it! @WomensCenterorg

INCIDENT: We are currently monitoring an unidentified flying sleigh entering NATO airspace. The track originates from the North Pole and is flying an erratic path🎅
No NATO jets have been scrambled.
Congratulations @NASAAdmin @rookisaacman !
Today, Jared Isaacman (@NASAAdmin) was sworn in as NASA’s 15th Administrator. At a time of intense competition across the last frontier, he will lead the most talented minds in the nation to ignite the orbital economy, usher in world-changing scientific discovery, and return American astronauts to the Moon – this time, to stay.
America’s historic mission in space continues. 🚀 go.nasa.gov/4s5NYGE

Calling all government employees! This means you, @NASA ! NASA has been the best place to work in the federal government for large agencies for 13 years straight, but we need all government employees to take the survey! Survey closes Dec 19 so please take it NOW!
Are you a current federal employee? In the absence of the 2025 FEVS, we created the Public Viewpoint Survey to assess today's federal employee view on their jobs and workplaces.
Have your voice heard. Complete the survey today. ➡️ourpublicservice.org/PSVS
