NASA has a proposal to re-commission the OSIRIS-REx spacecraft for the exact purpose. It's healthy, & up for a 2029 mission—total cost $200 Million, $50 Million already spent. President Trump wants to kill it. Here's more on the OSIRIS-APEX mission - osirisrex.arizona.edu/osiris-apex

NASA released some shape models of four of Saturn's moons. These have every lump and bump; they're not simple spheres.

Here's a test render I did in #Blender showing #Mimas in false color - red is high, blue low. Clearly shows how non-spherical it is!

A federal judge in Boston said she found it "difficult to conclude anything other than that [the Trump administration] used antisemitism as a smokescreen for a targeted, ideologically-motivated assault on this country's premier universities, and did so in a way that runs afoul of [federal law]."

In order to get a weather forecasting job with the National Weather Service, applicants now have to name at least two Trump Executive Orders and state how they plan to help support them. Which is ridiculous and shame on every MIC that allows that nonsense in their WFO!

This is a shocking executive order that undermines the very idea of open inquiry. It turns federal grants into dispensations, subject to arbitrary and capricious withdrawal should the recipient say or believe the wrong things.

Breaking from @science.org: The Trump administration wants to kill off a host of active and healthy NASA climate and planetary spacecraft. It would be a "leaner, more focused" agency, they say -- and one far less capable of studying the Earth and exploring space.

Wow. This proposes cutting over 1300 civil servants from NASA Goddard, a 46% cut in staff.
Also, the budget proposal would cut NASA's civil service workforce by a third.
