Kowalski asks Stone about her life back home and learns that her daughter died in a schoolyard accident. With Stone's oxygen reserve running low, they float through space to the ISS. Kowalski estimates they have 90 minutes before the debris field completes an orbit and threatens them again. Kowalski decides to use the thruster pack to get to the International Space Station (ISS), which is in orbit about 100 km (60 mi) away. The shuttle's interior has been ripped open by debris and the remainder of crew are dead. They find that the STS Explorer has been catastrophically damaged. He flies them back to the STS on the way they find the engineer Shariff ( Phaldut Sharma), his helmet smashed and his skull mostly open and empty. Kowalski, who is wearing a thruster pack, suddenly appears and attaches her tether to him. Stone panics, trying to contact Houston or Kowalski. Once free, she is thrown far from the STS. A piece of debris breaks the robot arm off from the STS, and Stone is forced to release the tether holding her to the robot arm. High-speed debris strike the STS, sending it spinning wildly, with Stone at the end of the boom arm. Within a couple of minutes, they lose contact with Mission Control, though Stone and Kowalski continue to transmit 'in the blind', hoping that the ground crew can hear them. Houston tells them that debris from a Russian missile strike on a defunct satellite has caused a chain reaction, destroying other satellites, and a huge debris field is heading right at them. Mission Control (voice of Ed Harris) suddenly instructs them to abort their spacewalk and return to the STS. She is on a spacewalk repairing a panel on the Hubble Space Telescope, accompanied by veteran astronaut Matt Kowalski ( George Clooney), who is commanding his final expedition. Ryan Stone ( Sandra Bullock) is a Mission Specialist on her first space shuttle mission, STS-157.

The synopsis below may give away important plot points.

Through the process, they are often on their own without the other leading to an extreme feeling of isolation which leads to individual questions and ultimate decisions about their own mortality and what may be best for the other at the expense of oneself. Even if he can retrieve her and get her some oxygen, they have the difficult task of trying to get to another satellite with whatever equipment is on hand, and from there ultimately back to Earth.

The two are left in a precarious position as Stone is untethered with quickly decreasing oxygen on her person meaning that Kowalski has to retrieve her quickly if she has any chance of survival. Before the crew can do anything about it, the explosion debris comes hurtling toward Explorer, irreparably damaging the shuttle and station, immediately killing all the crew except Kowalski and Stone, and knocking out at least incoming communication with Houston control, although they have no idea if there is outgoing communication. Ryan Stone - who is on her first ever space mission - and flight engineer Shariff Dasari are on a space walk when they learn from Houston control that an explosion has just occurred at a Russian satellite.

Mission Commander Matt Kowalski, medical engineer Dr. The crew of the Space Shuttle Explorer is working on the STS-157 mission.
