Any journalists want to write an article about all the environmental costs of the more than 10,000 Starlinks that are now in orbit? All I'm seeing are breathless articles mindlessly worshiping That Awful Billionaire for crossing the 10,000 satellite mark.

Every single one of those will come down in an uncontrolled reentry. That's a lot of metal in the atmosphere, and a lot of dice-rolling to see if any more pieces will make it to the ground.

SpaceX is truly awful.

Ventura County dam disaster day, which almost no one knows about.

Sky Glows over Paranal Observatory

Explanation: Are lasers from giant telescopes being used to defend the Earth? No. Lasers shot from telescopes are now commonly used to help increase the accuracy of astronomical observations. In some directions, Earth atmosphere-induced fluctuations in starlight can indicate how the air mass over a telescope is changing, but in other directions, no bright star exists. In these directions, astronomers can create an artificial star with a laser. Subsequent observations of the artificial laser guide star can reveal information so detailed about the changing blurring effects of the Earth's atmosphere that much of it can be removed by rapidly flexing a telescope's mirror. Such adaptive optics techniques allow high-resolution ground-based observations of real stars, planets, and nebulas. Pictured here, telescopes at Paranal Observatory in Chile study a colorful sky filled with green airglow and the Magellanic Clouds on the left, red airglow on the right, and the majestic central band of our Milky Way Galaxy arching across the center.

Deadlines for comments on a million SpaceX "AI data centers" and a company that wants to deliver "sunlight as a service" are coming up soon. If you have time and energy, please write a comment! Instructions below.

(I heard a rumour that Reflect Orbital is on-track to have the most comments on an FCC filing ever. Seems like a good goal to beat the record writing responses to this incredibly fucking stupid idea)
