The Space Shuttle Explorer, commanded by veteran astronaut Matt Kowalski, is in Earth orbit to service the Hubble Space Telescope (HST). Dr. Ryan Stone is aboard on her first space mission, to perform a set of hardware upgrades on the Hubble. During a spacewalk, Mission Control in Houston warns Explorer‘s crew about a rapidly-expanding cloud of space debris caused by the Russians having shot down a presumed defunct spy satellite (see Kessler syndrome), and order the crew to return to Earth immediately. Communication with Mission Control is lost shortly thereafter as more communication satellites are knocked out by the debris.Gravity full Movie Download.
High-speed debris strikes the Explorer and Hubble, tearing Stone from the shuttle and leaving her tumbling through space. Kowalski, using a Manned Maneuvering Unit (MMU), rescues Stone, and they return to the Explorer, soon discovering that the Shuttle has suffered catastrophic damage and the rest of the crew are dead. Stone and Kowalski decide to use the MMU to reach the International Space Station (ISS), which is in orbit about 1,450 km (900 mi) away, Kowalski estimating that they have 90 minutes before the debris field completes an orbit and threatens them again.
On their way to the ISS, the two discuss Stone’s home life and her daughter, who died young in an accident. As they approach the station, they see that the ISS’s crew has evacuated using one of its two Soyuz spacecraft, the remaining Soyuz’s parachute having been accidentally deployed in space rendering it unable to return to Earth. Kowalski suggests using it to travel to the nearby Tiangong space station, 100 km (60 mi) away, in order to board the Shenzhou spacecraft to return safely to Earth. Out of air and maneuvering fuel, the two try to grab onto the ISS; the duo’s tether snaps on one of the station’s solar panels. Stone’s leg gets entangled in the Soyuz’s parachute cords and she grabs a strap on Kowalski’s suit, but it soon becomes clear that the cords will not support them both. Despite Stone’s protests, Kowalski detaches himself from the tether to save her from drifting away with him. Stone is pulled back towards the ISS, while Kowalski floats away.
