[quote="Francisshoug" post=55174]Often, when spaceborne garbage hurtles back toward Earth, objects such as defunct rocket parts are torn apart by the jarring physics as they can slam into Earth’s thick inner atmosphere while still traveling at more than 17,000 miles per hour (27,000 kilometers per hour).

Each of the pieces from the rocket part can then pose a threat to the area where it lands. 
 
But Cosmos 482 was well suited to make the trip home in one piece. The spacecraft had a substantial heat shield that protected the vehicle from the intense temperatures and pressures that can build up during reentry.

And because Cosmos 482 was designed to reach the surface of Venus — where the atmosphere is 90 times denser than Earth’s — the probe likely remained intact. 
 
The Soviet Venera program 
The Soviet Union’s Space Research Institute, or IKI, ran a groundbreaking Venus exploration program amid the 20th century space race. 
 
Venera, as the program was called, sent a series of probes toward Venus in the 1970s and ’80s, with several spacecraft surviving the trip and beaming data back to Earth before ceasing operations. 
Of the two Venera vehicles that were launched in 1972 , however, only one made it to Venus. 
 
The other, a spacecraft sometimes cataloged as V-71 No. 671, did not. And that’s why researchers believed that Cosmos 482 was the failed Venera vehicle. (Beginning in the 1960s, Soviet vehicles left in Earth orbit were each given the Cosmos name and a numerical designation for tracking purposes, according to NASA.)[/quote]
