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.

[Bethany Stevens @NASASpox]

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.

"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.

Melroy: “An incredibly exciting moment… the first step toward a moon base.”

Cassidy: “They’re on cloud nine.”

A new era of space exploration.

[Koichi Wakata 若田光一 @Astro_Wakata]

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

Congratulations @NASAAdmin @rookisaacman !

[NASA @NASA]

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. 🚀 https://t.co/zbSZLTZFiv

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!

[The Partnership (@ourpublicservice.bsky.social) @publicservice]

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. ➡️https://t.co/4ya24OASWW

[Captain Mark Kelly @CaptMarkKelly]

NASA revealed they found some of the building blocks of life in a sample brought back from an asteroid (on a @UArizona-led mission, by the way).

It raises some big questions about whether there’s other life somewhere out there in the universe. According to my math, probably.

[NASA @NASA]

Off they go! @Astro_ChrisW is embarking on his first-ever flight to space. The crew aboard the spacecraft will spend eight months conducting research on the @Space_Station.
