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...

As he completed the first ever US spacewalk on June 3rd, 1965, Ed White said: “I'm coming back in... and it's the saddest moment of my life.” It’s a relatable sentiment for far too many in the US space community right now!

Read about it here, in PSJ, just out in the winter! doi.org/10.3847/PSJ/...

Brian Jackson of @boisestate.bsky.social just showed us how he's able to measure wind speed and direction from the tilt of the Ingenuity helicopter on Mars in flight! This is fantastic since the wind sensors on the rovers were damaged. Wind has been something we're missing! 🧵 🧪🔭 #planetsci

We're advertising a 3-year postdoc post on long-term solar activity reconstructions, using data from tree rings, ice sheets, sunspots and spacecraft. Closing date: 4 June. jobs.reading.ac.uk/Job/JobDetai...

I've been feeling especially good about my @planetarysociety.bsky.social membership lately. Kudos to @caseydreier.bsky.social, Bill, Jennifer, and the rest of the team for helping bring some sunlight to the inspiring parts and the scary parts of what the future of planetary exploration could be.

Technological capabilities, national priorities, and budget constraints have aligned to make low-cost Mars exploration a major focus of the coming years. Ingenuity showed a way to be bold without breaking the bank. Please read my new OpEd in Space News for more! spacenews.com/where-no-rov...

On March 1, the Europa Clipper spacecraft will soar past Mars, using that planet’s gravity to shape its trajectory, sending it first back by Earth, then on toward its 2030 rendezvous with Jupiter. Onward and upward! #Europa #EuropaClipper www.nasa.gov/missions/eur...

I have been so excited since I found out this would be announced today! RIP any ability for me to concentrate: www.apple.com/tv-pr/news/2...

Four years ago, the Perseverance rover (with the helicopter Ingenuity safely stowed inside it) safely touched down on the surface of Mars. My wife was one of 100s of bad-ass engineers, scientists, technicians, etc who pulled miracles out of hats to make this happen. youtu.be/HHhyznZ2u4E?...

Congratulations to Sydney Diaz, a sophomore of @meam-penn.bsky.social , and Annie Gao, a sophomore studying Electrical Systems Engineering (ESE), for being selected for the 2025 Brooke Owens Fellows. www.brookeowensfellowship.org/blog/posts/c...

I'm getting to my annual traditional a little late, given the chaos of the world right now. Still, I always enjoy doing this. Here's my year in books! Here's what I read, in the order I read it. Thanks to all of the authors for their work -- creating a book is a labor of love!

Socrates himself famously said, "the uninteresting life is not worth living" shortly before he died. Okay, he actually said "the UNEXAMINED life is not worth living" but I punched it up for him for free qwantz.com/index.php?co...

In next few hours (if schedules hold), two different Google Lunar XPRIZE heritage teams will launch their latest robotic lunar landers aboard the same rocket.

I am proud of my AeroVironment Mars helicopter team! Along with our friends from NASA JPL and La Cañada Flintridge, we won the Innovation Award for the 2025 Rose Parade with the first flying drone as part of the float (among many other firsts!).

Very cool, very uncommon job opportunity: apply now to be the (co-) Executive Director or the Director of Operations for the Open Lunar Foundation. If you are an aerospace professional seeking a new opportunity as we roll into a new year, these are excellent jobs www.openlunar.org/blog/hiring-...

Another good day of operations on Europa Clipper! And it’s great to know that all science instruments have been turned in successfully at least once! #europa #clipper #jpl #nasa

Russian EVA 63: This was the 272nd ISS spacewalk, the 3rd so far this year, the 2nd for Ovchinin and the 1st for Vagner. Total ISS EVA time now stands at 1,723 hours and 13 minutes, or 71 days 19 hours and 13 minutes; Ovchinin has now logged 13h 18m outside the station in his 2 EVAs (2/2)

Hey #SciArt folks, you’ve got till the 23rd to submit to the Art of Planetary Science show! This is a great annual event organized by grad students at UofA, which I founded >10 yr ago :) This year's theme is 50 Years of Mystery and Discovery on Mars. You can participate remotely! lpl.arizona.edu/art

Grateful for @rocketksc.bsky.social’s play-by-play of today’s Russian spacewalk. In addition to my general space nerdiness, My wife is on shift in Mission Control as Flight Director today, so it’s been a great way to keep up with what she’s doing. You’re the best, Bill!

Russian EVA 63 (05:36 ET; 4:12pm EST; 2112 UTC): Ovchinin is the first cosmonaut to "ride" the arm since the appendage was launched in 2021. Ovchinin and fellow spacewalker Ivan Vagner originally planned to relocate an external control panel for the arm, but that task was deferred to a later EVA.

Nicky Fox told me today that that is indeed the plan, choosing ideas ala carte.

Via Irene Klotz (Av. Week), NASA Administrator Bill Nelson says he plans to announce the new architecture for Mars Sample Return in early January — presumably only days before leaves office. NASA has had multiple parallel groups, some within NASA and some in industry, studying new architectures.

Last week, several teammates and I presented an e-poster at the #AGU24 conference highlighting a few of the science capabilities of future Mars helicopters. 📜: agu24.ipostersessions.com/Default.aspx... 🧵👇

Here’s something cool announced last week… on Christmas Eve the Parker Solar Probe will make its fastest (430,000 mph) and closest (3.8 million miles) approach to the Sun! Breaking its own records for speed and closest approach to our star.

Today, our colleagues at @NASA gave an update on the joint @NASAJPL + @aerovironment investigation into Ingenuity's final flight. A thread 🧵

Hello Blueksy! NIST is seeking a motivated scientist to join the Fire Research Division in our efforts to model wildland, wildland-urban interface, and prescribed fires! Please reach out if interested. #postdoc #science #wildfire

At this point, 20% of Brooke Owen + Patti Grace Smith Fellowship (volunteer) executives have been to space. I’m starting to like my odds! 😂

Calmly narrating key flight milestones while pulling three g’s, then likening her astronaut Overview Effect to seeing her children right seconds after giving birth. Name a more iconic Emily Calandrelli moment. So happy for my friend and Brooke Owens Fellowship colleague! 👩‍🚀👸🏻

PSA: Be weary of content #scraper accounts on this platform. They are popping up in large numbers and share stolen images (i.e. without credit or permission), often for their own monetary gain and without any valuable context. 🔭 (1/6)

I’m so delighted to see Emily Calandrelli among the crew of the next Blue Origin flight. I’ve known Emily since she was a NASA Academy student (Gerry Soffen would be so proud to see this news), and feel very lucky to have worked with her on the Brooke Owens Fellowship and more. Godspeed, Emily!

Wow, does ABL’s path seem uncannily family to former Virgin Orbit folks. Commercial small launch to responsive launch to UK and Omani launches to missile defense. I genuinely hope it works out better for ABL than it did for VORB.

Privileged to see @NASARoman being assembled in the high bay cleanroom @NASAGoddard today!

Philae was the 1st spacecraft to touchdown on a #comet OTD ten years ago. But because it bounced and thus landed somewhere unplanned, we did not know exactly where Philae was for another 2 years! Can you spot Philae in this image taken on Sept. 2, 2016 by the OSIRIS camera? #planetaryScience 🧪🔭🚀🛰️
