#Clouds are collections of fine #waterdroplets that have formed around #condensationnuclei and move within the Earth's #atmosphere. They are visible for us due to the #Tyndalleffect. The influence of clouds on #globalwarming is complex and subject of current #research (link Nature Geoscience editorial, 2024). The ESA/JAXA/NICT #satellite #EarthCARE studies the #influence of clouds on Earth's #climate.

#Trump ally #ElonMusk's #rocket & #satellite company #SpaceX has emerged as a frontrunner alongside #software firm #Palantir & #drone maker #Anduril to build key components of the system, Reuters reported last month.

Many of the early systems are expected to come from existing production lines. Attendees at the WhiteHouse presser w/Trump on Tues named #L3Harris, #LockheedMartin & #RTXCorp as potential contractors for the massive project.

#Trump's South African-born adviser [& fellow #WhiteSupremacist] #ElonMusk has also been highly critical of #SouthAfrica's govt. He has slammed the country's affirmative action laws, which he says prevent his #Starlink #satellite company from entering the market🎻. On Tues, reports suggested that #Ramaphosa might offer the #Tesla billionaire some kind of deal ahead of his White House meeting [don’t do it!].

Yikes, a lot of the predicted path is over land. ± 10 mins before the predicted reentry time, it's entirely over land. This was designed to deal with the high temperatures of Venus entry, so remaining intact and impacting is the likely scenario. Let's just hope that it lands somewhere unpopulated, but we still learn a lesson.

World map with tracks of the spacecraft over 6 orbits in the 8 hour window.
FosstodonAkaSci 🛰️ (@AkaSci@fosstodon.org)Attached: 1 image You are all aware of the uncontrolled reentry of the failed Soviet era COSMOS 482 Venera Venus lander tonight. Here is the trajectory map from Aerospace Corp. with some added annotations to help make sense of it. It shows 6 orbital tracks over 8 hours centered around the expected reentry time. It will strike the ground along one of these tracks, but not between them. Reentry will occur near the northern end of the orbit. Launch date: Mar 31, 1972 Weight: ~495 kg https://aerospace.org/reentries/6073 1/n

A half-ton Soviet spacecraft is about to crash into Earth, but don't panic.

NBC News reports: "Kosmos-482 was designed to land on Venus but instead has spent the past 53 years languishing in Earth’s orbit because of a rocket malfunction." It's expected to enter Earth's atmosphere sometime on Saturday.

I Do Declare Tomorrow, May 10th 2025 As
"The Sky Is Falling" Day !!!

Because it is very likely that the Cosmos 482 (formerly known as Venera 4V-1 No. 671) will come crashing down on Earth, somewhere.

[BTW. It's a titanium alloy sphere, powered by a nuclear battery, which weights 1,091 lbs and is highly likely to reach the surface of Earth in one piece as it was designed to withstand 300 g of acceleration and 100 atmospheres of pressure.]
