I knew the images would be good, but nothing prepared me for the end result. Just... wow. I think we can say that the Psyche-Mars flyby was a huge success 😍 www.nasa.gov/missions/psy... #MissionToPsyche
From NASA The initial reports are in: #MissionToPsyche aced its Mars flyby. ☑️ With the Red Planet in the rearview mirror, the spacecraft will resume using its solar-electric propulsion system to make a beeline to the main asteroid belt and rendezvous with the asteroid Psyche go.nasa.gov/4dn30CI
Psyche captured this sequence a few hours later during closest approach when Psyche was about 5000 km above Mars. The sequence starts over Isisdis Planitia, moves across Syrtis Major (a bit south of where Perseverance is) and ends over Huygens crater.
Two worlds: Earth, taken by the Artemis II crew and Mars, taken by the Psyche probe... I wonder when human eyes will see Mars as a crescent like this... Earth image: NASA Mars image: NASA/JPL-Caltech/ASU Additional processing: S Atkinson
De nouvelles images acquises par la sonde #Psyche continuent d'arriver sur Terre via le Deep Space Network ! J'en ai ajouté 5 à ma mosaïque précédente, maintenant on distingue bien Syrtis Major Planum (plaines sombres cratérisées en bas de l'image) de Isidis Planitia (plus claire en haut). 1/3
Looks like some of the first images of Mars' surface are down from the Psyche encounter. Images from camera A so far, and no color yet. flic.kr/p/2sdxp6e flic.kr/p/2sdsK58 flic.kr/p/2sdyE2N flic.kr/p/2sdyFQs

For @msnownews.bsky.social, I wrote an article about how ICE Watch is grounded in sociological theories of violence prevention. The reality is that most men will only commit public violence in extremely specific scenarios and ICE Watch disrupts the conditions necessary for escalation.
Opinion | I'm a Minneapolis sociologist who studies violence. Here's how ICE observers are helping.
Research into how violence occurs shows that disapproval from the people around you can help reduce it.

Just watched The Rip and my review is: Any movie under 2 hours is ok in my books. Also, seeing Ben and Matt on screen together is never a bad thing. 5 out of 10. Totally predictable, then it's not, and then... oh yeah, I knew he was the bad guy. Silly fun with a lot of shooting in the dark.
Just watched "Weapons" and it turns out that my review for the movie is exactly the same as my review for 2025: Gross, tragic, dumb, too long, and poorly executed.
Saturn's largest moon, Titan, has been a member of the deep-sea club for almost 2 decades. New research might revoke its water world card. 🪐 🌊 My 2nd #AGU2025 story of the week for @science.org : www.science.org/content/arti... #space #titan #nasa
Titan might not have an ocean after all
A reanalysis of data from NASA’s Cassini mission suggests Saturn’s icy moon may lack the subsurface ocean presumed for a decade

I wanted to do a quick thread about this paper led by a great postdoc here at JPL, Flavio Petricca, which suggests that Titan may not have a global ocean after all. www.nasa.gov/solar-system...
NASA Study Suggests Saturn’s Moon Titan May Not Have Global Ocean - NASA
A key discovery from NASA’s Cassini mission in 2008 was that Saturn’s largest moon Titan may have a vast water ocean below its hydrocarbon-rich surface. But

Saturn's moon Titan may not have a buried ocean as long suspected, new study suggests
Saturn's giant moon Titan may not have a vast underground ocean after all. New research suggests Titan instead may hold deep layers of ice and slush more akin to Earth's polar seas instead of a buried ocean as long suspected.

Cassini, Saturn, and Titan, what's not to love? 🛰🌕📡 A new Nature study, led by JPL scientists, has taken a new look at archived gravity data from NASA's Cassini mission to reveal that, perhaps, Saturn's largest moon Titan does not have a subsurface ocean: www.jpl.nasa.gov/news/nasa-st...
NASA Study Suggests Saturn’s Moon Titan May Not Have Global Ocean

This budget request would cripple NASA's space science efforts. Active and planned science missions scrapped. $ billions of wasted taxpayer money. This is sick. www.science.org/content/arti...

National missile defense is the longest-running scam in the history of the Department of Defense. Musk didn’t invent it, but he’s about to get a whole lot richer by perpetuating it. https://trib.al/Qpb9WJE
Trump’s “Golden Dome” Won’t Work—but It’ll Make Elon Musk Richer
For 40 years, missile defense has never been about keeping America safe. It’s all about the contracts.
