I’m absolutely thrilled to share that NASA chose Anna Menon, my friend and former SpaceX Space Ops teammate, for the 2025 Astronaut Candidate Class! www.nasa.gov/news-release...

During a visit to NASA’s Johnson Space Center last March, I was confronted with an environment of fear, uncertainty and discrimination which struck me as a troubling moral issue that also raises serious safety concerns. Read all about it here: www.thespacereview.com/article/5060/1

As part of the Peaks & Professors program, I hosted a group of USC students on a trip to Sequoia National Park last weekend. Huge trees, amazing views, great night sky, super fun students and pop-tarts for breakfast!!!

Very impressed last night by Abagail Spanberger and Mikie Sherrill, candidates for Governor of #virginia & #newjersey who are focused on improving affordability in their states no matter what happens nationally. I’ve known Mikie Sherrill for >7 years and can’t think of a better leader for NJ.

Trump’s NASA policies could jeopardize America’s decades of dominance in space.

Only someone who avoided the draft would want to rename the Department of Defense to the Department of War.

We flew our airplane to Telluride CO to visit with my boon companion, Mike LA, and see an incredible film at the #telluridefilmfestival ‘From Earth to Michael’ is about a father-son relationship that spans years, spends time in space and endures per aspera. Hopefully you will get to see it soon!

Congratulations to all my friends at SpaceX on what I’d definitely classify as a successful test flight of #Starship today! Still a lot of work to do to improve the aft flap thermal protection but heading in the right direction again!

Nukes on the Moon - hear my take on @cnn.com Spoiler alert - I actually think it's not a bad idea... youtu.be/OyL1I43ztcw

Hey! What’s wrong with Parsippany? Pick on Livingston next time.

Great article by Jackie Wattles @cnn.com about the Voyager Declaration. I will share more details about my thoughts on what's happening at NASA soon, but wanted to spread the news about the public release of this letter today. www.cnn.com/2025/07/21/s...

💔 - But on the other hand, the next 10 months of The Late Show With Stephen Colbert will be legendary...

The Space Shuttle Endeavour exhibit at the California Science Center is nearing completion and I can tell you that it will inspire so many people to become engineers, scientists and astronauts. We're getting there, but still need your help getting across the finish line. youtu.be/bqMolALdVGg?...

NASA’s science programs are some of the most cost-effective work that the agency does. And they are being decimated.

All Living Former NASA Science AAs Protest FY 2026 Budget Cuts: nasawatch.com/congress/all... #NASA

One thing is very clear right now. Anyone who claims that the Republican Party is serious about reducing the deficit or helping the middle class and is not all about cutting taxes for billionaires instead doesn’t have a leg to stand on.

On this day in 1983, Space Shuttle Challenger launched on its second mission - carrying Sally Ride, the first American woman in space. She was also the first Astronaut known to have been LGBTQ+, though she was not able to publicly come out until after her death. We Believe In Astronauts™

The drive-through protesters with their signs and flags were so LA. 😄. #NoKings Torrance, CA

The South Bay showed up today bigly for the #NoKings protest in Torrance, CA!

Congratulations to Mikie Sherrill for winning today’s Democratic primary for Governor of the great state of New Jersey! I can’t say enough about the strength of her character and leadership. She’ll make an excellent Governor. Let’s go!! @stateofnewjersey.bsky.social @mikiesherrill.bsky.social

Here's my take on the Trump-Elon shitshow and how integral SpaceX is to the US government space program. As told to the BBC youtu.be/hSAGFdhZlGY

We did make it to air on @cnn.com late last night! ICYMI here's a link to the interview. youtu.be/IBniAdCMhYk

I’m not rooting for it, but even as nasty and seemingly irreversible of a breakup this is, I wouldn’t be shocked if Trump and Elon kiss and make up. They both stand to lose bigly in this divorce and they both know how much attention the reunion episode would generate.

Sorry, but restoring funding to Gateway is nowhere near as important as restoring funding to NASA's science missions. This $2.6B for Gateway alone would be more than half of the money required to keep NASA's science missions intact.

I'm one of many who will say today that I totally predicted this, but I honestly thought it wouldn't happen this soon. Elon has shown in the past that he is capable of sustained faux deference to achieve a tactical goal. But apparently something snapped this time. www.nytimes.com/live/2025/06...

Just kidding! My segment was pulled at the last minute because of all the Elon-Trump breaking news. And as bad of a day those two guys are having, things aren't looking too good for Resilience either. We have no official confirmation from iSpace but it seems like this was a failed landing attempt.

About to go live on @cnn.com to cover the iSpace lunar landing attempt. Tune in and join us!

So sorry to see this terrible news. As a rookie astronaut you are randomly assigned officemates when you first show up to NASA and one of them was Marc Garneau. He could not be more kind and helpful. He was an excellent representative of his country and of us all. www.ctvnews.ca/montreal/art...

Nuclear Thermal is the most promising next-generation propulsion technology for human interplanetary spaceflight. And we're giving up on it, apparently.

Unless these decisions are reversed, this will be remembered as a disastrous week for @NASA. First, I am not optimistic that whomever this administration nominates next for NASA Administrator will be nearly as qualified or enthusiastic about the agency’s mission as Jared. 1/

Pretty launch. But attitude control on Starship seemed a little … ummm… not.

Last night was joyful & poignant-the wedding of Noaa Ramon & Ron Eliav. I’ve known Noaa since she was 2. She is the daughter of the first Israeli astronaut, Ilan Ramon, and the first of Ilan & Rona’s children to marry. For too long, this family has been getting smaller. But last night it got bigger.

Today my Ph.D. student, Ulubilge Ulusoy, graduates and participates in the age-old hooding ceremony tradition. I’m very proud of this smart, talented and promising young man and can’t wait to see what he does next!

15 years ago today mission STS-132, the penultimate flight of the Space Shuttle Atlantis, launched from the Kennedy Space Center. 15 years! Can’t we find a way to make time slow the F#&@ down!!

Last week at the Endeavor Awards I got to present an Inspiration Award to the Polaris Dawn Crew for successfully completing the first commercial space walk! It was a thrill to hand the award to spacewalker Sarah Gillis who worked with me as an intern at SpaceX years ago. Sniff…they grow up so fast!

15 years. Damn!

I had a pretty amazing TA for my class at USC this semester... viterbischool.usc.edu/news/2025/05... @viterbischool.usc.edu

Because no one spends as much on science as the US does, destroying NIH, NSF, NOAA, NASA, EPA, USDA, USGS, etc. is leading to a brain drain, but it's not to other countries but rather from science. This senseless destruction of US science will hurt the US and the world for a very long time.

This is a terrible budget proposal for NASA. While some cuts are justifiable, the largest part of the $5B cut comes out of space science including eliminating funding for "low-priority" climate monitoring satellites. Eliminating climate change research funding doesn't make the problem go away.

Happy 80th anniversary of Hitler killing himself in his bunker to all who celebrate, which, as I now understand it, is not everybody

Of course he doesn't. Trump is equally happy to support either Jews or anti-Semites - as long as doing so serves his own interests. Remember, there were "very fine people on both sides" The day he calls out the anti-Semites in his camp is the day I might believe him. www.nytimes.com/2025/04/28/o...

Nice article about how we try to get the tech right on 'For All Mankind' on AppleTV+ Season 5 coming out soon! Thanks for the shout-out, @slashfilm.bsky.social ! www.slashfilm.com/1836400/appl...

"The Trump 'peace' plan is no such thing; it is an instrument of surrender, and the Ukrainians are unlikely to accept it," @radiofreetom.bsky.social writes: https://theatln.tc/zI63nuAf

Great flight over downtown LA tonight. #flying #losangeles

Ukraine is beating Russia—sinking their fleet without a navy, killing 800,000+ invaders, and holding the line for 3 years. Donald Trump wants to save Putin. He won’t say Russia is the aggressor. Let’s be clear: there’d be a cease-fire if Russia…stopped. adamkinzinger.substack.com/p/ukraine-is...

Widespread and massive protests, civil disobedience and strikes are our only hope for turning the tide in the US over the next two years. www.nytimes.com/2025/04/17/o...

I was very sad to hear that Elaine Wynn passed today. She was so kind and caring, and was a true believer in the power and importance of education for each and every kid. She took a deep interest in all of her foundation's beneficiaries - her philanthropy was personal. Godspeed, Elaine.

Come join me at the Endeavor Awards on May 9th in Los Angeles. It's a super fun night benefiting a great bunch of philanthropic aviation organizations. You can buy tickets here: endeavorawards.org
