Here at @NASA, humanity’s capacity to discover—and America’s capacity to lead—shines bright. Thank you to the NASA family, who embodies the can-do spirit that makes our country exceptional. It has been the honor of my life to stand and serve with you.

Exciting news: @UFPress republished my 1988 book MISSION: An American Congressman’s Voyage to Space, with a new preface. Nearly 40 years ago, I predicted much of what’s happened in space today. It’s been a privilege to be part of this ongoing journey. https://t.co/cl54Jacue4

Astronaut Jim Lovell has died at age 97. He was a pioneer..Gemini, Apollo 8 the first flight to the Moon, then a miracle of safe return of Apollo 13 after an explosion in flight. Jim was one of the best and a gentleman and devoted husband. Godspeed Jim.

I spoke out against the dangerous consequences of cutting science funding alongside @SenMarkKelly. These attacks don’t just set us back—they create a culture of fear and intimidation that puts lives at risk, including the safety of our astronauts.

Trump’s budget jeopardizes America’s foothold in space while our adversaries soar ahead. If we let others take the lead, we’ll wake up in a world playing by their rules. Read my @nytimes op-ed:

Marc Garneau, Canadian Astronaut has died at age 76. He was a trailblazer in our space relationship with Canada and the robotic arm on the shuttle. In Parliament he headed Transport and the Foreign Ministry. Jeremy Hansen who will fly to the moon, follows this Canadian champion.

These cuts aren't belt-tightening—they're a meat-ax to America’s future. Time to stand up for NASA and the world's finest workforce.

Now that Butch and Suni are home, I thank the good Lord and the people of NASA for all of their hard work, the testing and retesting to find out why the jets were misfiring. At the end of the day the vote was unanimous to bring them back on Dragon. Thank you.

I was happy to accept Dr. Francis Collins’ invite to join the Stand Up for Science rally to warn about savaging science in the U.S. budget.

Congratulations to NASA for being voted the best place to work in the Federal Govt in 2024! (13 years in a row.) The NASA team that I call wizzards are quite deserving of this honor.

Congratulations to Firefly Aerospace for the 2nd successful lunar landing for a US commercial spacecraft. The CLPS program is to utilize the ingenuity of the private sector to explore the moon with “scouts” in parallel with NASA. Onward to the moon!

My letter to the next NASA Administrator:

November 7, 1972 - January 20, 2025 As I leave public office today after 53 years, thank you for the great privilege of a lifetime of serving the people of our country. I am humbled and grateful. Bill Nelson

From the bottom of my heart, thank you to the heroic firefighters who protected @NASAJPL from the Eaton Fire—stopping the flames at our lab’s doorstep. Amid so much devastation in recent days, my heart is with our NASA family and everyone in California.

In this golden era of space exploration, a new generation of thinkers and leaders will light the way. This new partnership empowers our #Artemis Generation—opening doors for the brilliant researchers, faculty, and students who make Florida shine.

Congrats to @SpaceX on Starship’s seventh test flight and the second successful booster catch. Spaceflight is not easy. It’s anything but routine. That’s why these tests are so important—each one bringing us closer on our path to the Moon and onward to Mars through #Artemis.

Congratulations to @blueorigin on the first successful test flight of New Glenn. Together and in the spirit of John Glenn, NASA and our commercial partners are pushing the boundaries of exploration and reaching new heights—to the Moon, Mars, and beyond!

A NASA airborne instrument captured this false-color image of areas burned by the Eaton fire in Altadena as of January 11, 2025. Burnt trees and buildings in developed areas appear brown; burned wildland areas are orange. https://t.co/pVMdyZt5FG

Inspired by my conversations with the #Artemis Generation in Panama who are meeting global climate challenges with bold ideas and fresh perspectives. They represent a new source of action and understand that now is the time to unite and work towards a better future for all.
