This will not be an unwanted fall for space.
The failure of the Soviet Union Kosmos 482 spacecraft It will collide on the ground in the coming days after more than 50 years in orbit. Return to the homeland may not provoke the types of artificial bath that we are used to seeing From the fall of the bodies the missile However, other cuts of debris, because Kosmos 482 is designed differently: it is a Venus land.
“Since this is a cradle that was designed to survive through the flower atmosphere, it can escape the re -entering through Atmosphere Marco Langbrokik wrote sound and sound influence. The blog post recently.
“This is likely to have a difficult effect: I doubt that the parachute spreading system will continue to operate after 53 years and with dead batteries,” added Langbroek. “There are many unconfirmed factors in whether the drop will survive, including, including that this will be a long shallow re -entry path, and the age of the object.”
Kosmos 482 was part of the floors of the Soviet Union Venera program Explore Venus. The probe was launched towards the second planet from Sun In 1972, but he did not get there; Its missile suffered from anomaly, Kosmos 482 in an oval orbit around the Earth.
The clouds in the atmosphere have been pulled down slowly but steadily over the decades, and the time of Kosmos 482 is now up. According to Langbroek, the latest expectations of the spacecraft that belongs to Earth at about four in the morning ES (0800 GMT) on Saturday (May 10). However, uncertainty is very high – plus or minus 20.6 hours.
The orbital inclination in Kosmos 482 is 52 degrees, so the re -entry of the craft will occur between 52 degrees north and 52 degrees south – a large percentage of the surface of the earth. The experts cannot say much more than that at this stage, given the big error tapes in the timing. (These errors will become smaller and smaller as Kosmos 482 decreases, less and observers gather more data.)
However, the oceans cover about 70 % of the Earth’s surface, so we can say one thing: Kosmos 482 is likely to start in the sea.

According to Langbroek, Kosmos 482 is believed to be similar to Vanera 8 Lander, which was also launched to Venus in 1972 (but it is already safely there). If this is the case, Kosmos 482 width is about 3.3 feet (1 meters) and weighs about 1190 lbs (495 kg).
Modeling works indicate that Kosmos 482 will strike the ground (or waves) at about 150 miles per hour (240 km per hour), assuming that it does not explode during re -entering, according to Langberruck.
“The kinetic energy in the effect is similar to that of 40 and 55 cm [16 to 22 inches] Big (after detect) is a meteoric part, “Books.
But there is a lower reason than usual for fear of the “Death from above” scenario with Cosmos 482, given the durability of the craft.
“Because it is likely to reach the ground[‘s] The surface is only one object, and the risks involved are less than those created by a Falcon 9 Langbroek wrote that re -entering the upper stage, which acquires multiple creatures with a large size of a meter.
