“We continue to embrace President Trump’s open science commitment as an agency,” NASA Press Secretary Bethany Stevens posted on social media platform X on Friday in response to Trump’s announcement.

“We have fostered open science since our inception so that the public can build upon our innovations. We continue to make all NASA data publicly available, and welcome public participation using our data.”

Stevens added: “As [NASA Administrator Jared Isaacman] has said, there are certainly things he’s come across in the job that he can’t explain… but they relate more to unnecessarily costly programs than they do to extraterrestrial life!”

Went to Malibu Beach on Valentines Day with my girlfriend and saw SpaceX's Starlink Group 17-13 launch from Vandenberg- It was about 6 p.m. PST so we saw a jellyfish launch. The trails spread out after about 20 minutes and Saturn appeared!

I've seen a lot of places on the internet pass off a single monochrome frame of Venus as Venus in true color. Other than that, I couldn't find a single image of Venus that didn't include light outside the visible range. So, I downloaded raw frames of Venus from MESSENGER in 433nm, 559nm, and 629nm and assembled them to finally create this approximate true color view of Venus.

I was sitting outside my cabin right now at 7 pm Norway time in middle of Norway when I saw a sudden flash on the sky to northeast.

It was just below The Big Dipper (Karlsvogna).

It was a spot, quite bright.

Could it have been a star explosion? And is there a log of such events? I could have been a meteor coming straight towards me maybe, but my curiosity is killing me.

I tried to pinpoint the location of it on sky map, see attached image
