After 53 Years, a Failed Soviet Venus Spacecraft Is Crashing Back to Earth

![]() Kosmos 482 launched on March 31, 1972 from the Baikonur Cosmodrome spaceport in Kazakhstan. The mission was an attempt by the Soviet space program to reach Venus, but it failed to gain enough velocity to enter a transfer trajectory toward the scorching-hot planet. A malfunction resulted in an engine burn that wasn't sufficient to reach Venus' orbit and left the spacecraft in an elliptical Earth orbit, according to NASA. The spacecraft broke apart into four different pieces, with two of the smaller fragments reentering over Ashburton, New Zealand, two days after launch. Meanwhile, two remaining pieces, believed to be the payload and the detached upper-stage engine unit, entered a higher orbit measuring 130 by 6,089 miles (210 by 9,800 kilometers). The failed mission consisted of a carrier bus and a lander probe, which together form a spherical pressure vessel weighing more than 1,000 pounds (495 kilograms). Considering its mass, 'risks are similar to that of a meteorite impact,' Langbroek wrote. As of now, it's hard to determine exactly when the spacecraft will reenter. Langbroek estimates that the reentry will take place on May 10, but a more precise date will get clearer as the reentry date nears. Read more of this story at Slashdot.
