NASA-JPL hosted a panel discussion for #ProjectHailMary So many amaze (🎶) humans in one spot!!!
My colleague said Ryan Gosling mentioned, “Voyager was the original Hail Mary” 🥹
(Reminder- Matt Damon visited JPL + the Mars Yard for “The Martian”- which I alsooo missed!)

"Good night Moon." -SLS
NASA's #ArtemisII mission (SLS + Orion transported via Crawler) currently in rollback to the Vehicle Assembly Building (VAB) on Wednesday, 02/25/2026. Crews will begin troubleshooting shortly after SLS is tucked back in bed.

Today has been a full trip down memory lane. Grateful + proud to have been part of these NASA-JPL teams.
I’ll add to @sciencesocks.bsky.social @stim3on.bsky.social et al. posts. Here’s my real-time (albeit world-in-quarantine) M2020 landing day & “7 Minutes of Terror” from 2021:

HAPPY 5-(🌎)YR LANDIVERSARY to our Perseverance Rover 🍰
As a Jezero mapper, seeing the *image* from SkyCrane of M2020 being lowered to the crater surface, will forever be a highlight of my career.
CONGRATS to the entire M2020 Team (extra special shoutout to the EDL engineers!) 🧪🔭 #PlanetarySci

View of Crew-12’s launch vehicle and pad from the newly renovated Gantry at LC-39 (launch viewing area). A large “39” is embossed on the green astroturf in front of the viewing bleachers. Palm trees and a large body of water frame the distant Crew-12 launch pad. 📍Kennedy Space Center, Florida
We also got to see #Crew-12 a few days prior to their recent launch (and when they flew over the pad… didn’t get pics though 🛩️). Squint hard!

The bright orange SLS with Orion on Launch Pad 39B. SLS viewed from just beyond the pad’s security fence. Photo taken in Feb 2026. 📍Kennedy Space Center, Florida
Recently had the opportunity to reunite with some fellow NASA ASCAN Interviewees for an up-close tour of KSC + SLS/ Orion on Launch Pad 39B #ArtemisII
Putting together some thoughts, but here’s a sneak peek.

Learn how NASA trains astronauts on Earth for lunar (& future Mars) missions.
*Hey NASA- I’d love to help train future astronauts for Mars sedimentology/ geology. Aaand you already have my resume on record in Houston #DreamJob 🤝

NASA #ArtemisII schedule change:
Due to weather, the wet dress was shifted to Feb 2. That shifts the earliest launch window to Sunday, Feb 8.

The Hayabusa 2 spacecraft bus will encounter #asteroid Torifune on
5 July 2026.
"The time of the flyby has not yet been determined," but I figure 19 chances out of 24 that it will still be 4 July in *some* part of the US at the moment of closest approach. During our 250th birthday.

Last night I was finally able to image comet C/2025 K1. It took 3 mins exposure to get decent signal-to-noise (Bortle 8 skies, quarter moon, freezing temps) from my driveway. Nothing spectacular but still makes me smile. #astronomy #planetarysci

In the past few days, we've experiencing the beauty of Earth's magnetic field (hello #aurora). But, what about Mars?
Check out NASA's #ESCAPADE mission- launching *NOW* to study Mars magnetosphere!

Perhaps this should be tagged with #planetarysci, since it concerns planetary science.

Does anyone have experience publishing in Icarus "Notes"? The format seems appropriate for what I'm thinking, but I've just never published that type of article before. #PlanetarySci #Mars #Publishing

Lunar nightfall moving in tonight over Mare Crisium and Mons Latreille, where the BGM1 lander is located. Its not expected to survive the 14 days of darkness and cold.

A long stretched wispy cloud, almost shaped like a feather glows in the sky of Mars at dusk. The cloud shines in different colors, from blue near the horizon, to a yellowish-green on the other side.
Two years ago, NASA's Curiosity Mars rover captured this feathery iridescent cloud after sunset. The color is created by diffraction effects when sunlight is scattered by small CO2 particles in the cloud. #planetarysci

Our recent temporary "mini-Moon" neighbor, asteroid 2024 PT5, appears to be composed of the same stuff as the Moon.
T Kareta, et al, tell the story in ASTROPHYSICAL JOURNAL LETTERS:
"On the Lunar Origin of Near-Earth Asteroid 2024 PT5"

Sooo, I may or may not have just gotten in to my very first grad course at 21! When I was in high school, a counsellor told my family me going to college was “a stretch.” Let this be your reminder. Persistence pays off!
