Reorientation and despinning of 4 Vesta formed the Divalia Fossae
The Divalia Fossae are formed by tectonic stresses from reorientation and despinning of Vesta caused by large impacts.

Check out our new paper in Science Advances!
🧪🔭🪐
We show that Vesta’s giant equatorial troughs—Divalia Fossae—likely formed from spin axis reorientation and despinning as a long-term consequence of the two massive impacts near the south poles. 🪨⚒️

Abstracts submitted to LPSC 2026 are required to comply with White House (non-legally binding) executive orders forbidding mention of topics related to diversity, equity, and inclusion.
At least USRA/LPI isn't hiding it.
But is this what our community wants? Or deserves? I don't think so.

The best use of pennies is to drill holes in them and use them as washers, which typically cost 10 cents each.

Goddard spacecraft engineer: "I think it just kind of speaks to the atmosphere of the agency and the nation, where people are like, 'Well, laws don't matter for the people at the top anymore.'"
NASA is sinking its flagship science center during the government shutdown — and may be breaking the law in the process, critics say
"There is just a general acknowledgement that a lot of what is happening is illegal…"

This is the surface of Saturn's giant icy moon Titan, photographed by the Huygens probe on 14 January 2005.
It is the farthest place from Earth where we have so far landed.

Whenever I get Chinese food, I always make sure to get a second fortune cookie for my dog. I opened his up and read his to him: "You are adored by many." So true, he is.
I then open mine and...there was no fortune. The cookie was empty. Too real.

Layoff notices at JPL are going out today.
About 11% of the Lab, or 550 people, are being let go.
I'm thinking of my friends and colleagues there, some of whom will still be employed after today and some of whom won't.
I'm sorry you're having to deal with this.

A lot of comments on Mars rovers or Moon landings, but it's important to remember that the planet NASA studies most is Earth. This is less about cutting flashy things like moonwalks and more about keeping communities in the dark on climate, weather, agriculture, pollution, natural hazards, and more.
