The last of the Salyut space stations from the heyday of the Soviet space program, Salyut 7 tumbles into the Earth’s atmosphere, its supply of fuel exhausted. (No cosmonauts have occupied Salyut 7 since 1986.) With the large Kosmos 1686 expansion still docked, most of Salyut 7 disintegrates in the atmosphere, though some debris is scattered over Argentina. Salyut 7 lasted nearly nine years in orbit.
