paulhammond5155@lemmy.worldOPto Space@mander.xyz•Reentry prediction Soviet-era Venera Venus lander (Cosmos-482 descent craft) – Rocket Science0·25 days agoThe Russian space agency (Roscosmos)
Released the following on their Telegram channel… (Translated from Russian)
The device “Cosmos-482” descended from orbit and fell into the ocean
Launched in 1972, the spacecraft “Cosmos-482” ceased to exist, descending from orbit and falling in the Indian Ocean
The convergence of the device was controlled by the means of the Automated Warning System of Danger Situations in Near-Earth Space.
In accordance with the calculations of specialists TsNIIMash (part of Roscosmos), the device entered the dense layers of the atmosphere at 9:24 GMT 560 km west of the island of the Middle Andaman and fell in the Indian Ocean west of Jakarta.
The device was launched in the spring of 1972 to study Venus, but due to a malfunction of the upper stage remained in the high elliptical orbit of the Earth, gradually approaching the planet.

Leaks are never a good thing, hopefully the backup has enough xenon to complete the mission
paulhammond5155@lemmy.worldOPto Space@mander.xyz•A soviet spacecraft (lander) launched in 1972 is forecast for uncontrolled re-entry ~May 10, 2025English0·1 month agoIt doesn’t look like there is even an estimate yet of what part of the globe it will hit
Too early to predict that accurately. Our upper atmosphere expands and contracts depending on the activity of the sun, there can be large daily changes. An expanding atmosphere with slow the craft and it will de-obit quicker. A contracting atmosphere will allow the craft to stay in orbit a little longer. IIRC they won’t have an accurate time or a better idea of the impact site until about a day before reentry. I guess some folk are saying there is only a chance of making it to the surface as they don’t know if it is still intact.
At least one of the ‘experts’ that I’ve read firmly believes it will reach the surface as he analyzed its light curves a while back. I’m going with his prediction as that thing was built to survive tougher conditions than an Earth reentry. Odds are high that it will land in the ocean, but if it stays intact and hits land, then it’ll make a new hole in any golf coarse that happened to be in its cross hairs ;)
News media will likely start to report on it, as it gets closer to May 9th :)
Watch this space :)

That thing will make a mighty splash if it hits the ocean, either that or generate a good sized crater
Its older cousin (Curiosity Rover) is still trekking on the other side of Mars, right now it is the evening of sol 4537 and the rover has had another busy day exploring Gale crater. It’s been exploring Gale since August 2012. Here’s the data/ stats after its most recent drive a few days ago :)
Hopefully Perseverance will still be trekking after a similar time on Mars
