Happy #PiDay! Aboard the @Space_Station in December 2017, Expedition 53 Flight Engineer @astro_paolo posed next to AstroPi @Raspberry_Pi hardware that is intended to encourage and strengthen the teaching of computing and coding curricula and stimulate the curiosity of students!
There 🚀and back again 🪂
Helicopter catch! Stay tuned for more recovery details and payload deployment in around 50 minutes.
There was the space industry that existed before December 21, 2015 and the space industry that exists today. They are not the same. Congrats to @SpaceX and @elonmusk on building this moment to 100 orbital booster recoveries. The brain still thinks it's CGI.
Cheers at Starbase! The first ever Starship catching arm is moving for final assembly #starship
Internalizing advice is so hard. A superpower for those that do it well. So many chats go like this: Founder: "I'm going to do XYZ." Advisor: "Interesting. It's your startup, but FWIW I've seen 25 co's do XYZ and it didn't work." Founder: "Cool thanks. Anyway I'm gonna do XYZ."

Seeing NASA Mission Control celebrate a safe touchdown never gets old. 👏🏾👏🏾
It was fantastic to talk to President Elect @JoeBiden today about bringing the country back together. I’m here to help in any way I can.
Resilience rises. 🚀 The Crew-1 mission has lifted off on a Falcon 9 rocket from @NASAKennedy at 7:27pm ET and is en route to the @Space_Station. #LaunchAmerica
Consistently awed by the beauty of nuclear power plants, and by what they represent. The ability to create clean energy from matter, in a tiny geographical footprint, night and day, has to be one of the highest human achievements. I hope we start building them again!
Welcome home, @AstroBehnken and @Astro_Doug! We launched the Commercial Crew program to strengthen our U.S. space program and it's been great to see its success. This historic NASA-SpaceX mission is a symbol of what American ingenuity and inventiveness can achieve.
"Thanks for flying @SpaceX." 📍 Current Location: Planet Earth A 2:48pm ET, @AstroBehnken and @Astro_Doug splashed down, marking the first splashdown of an American crew spacecraft in 45 years. #LaunchAmerica
Kicking off our 5th (Virtual) Tech Summit today! We have a lineup of keynotes from our tech leaders @shklarski, @maayanroth, @redcat9, Christine Hung & @joshdefrain. Unconference sessions coming up soon 🥳 (Cooking lessons! Multimodal learning! And much more!)
Every week I get a message asking "Who is the version of you for Azure or GCP?" I don't know of anyone. I wrote a thread trying to motivate people to do this[1], so this thread will about more specific actions to do this. 1/ [1]
