Build a movie plot around this: What is Tiangong? A Chinese space station.
Answer:
In 2014/2015, bio-medical engineer Dr. Ryan Stone is a Mission Specialist on her first space shuttle mission, STS-157. She is on a spacewalk repairing a panel on the Hubble Space Telescope, accompanied by veteran astronaut Matt Kowalski, who is commanding his final expedition. Mission Control suddenly instructs them to abort their spacewalk and return to the STS. 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. 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.High-speed debris strike the STS, sending it spinning wildly, with Stone at the end of the boom arm. 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. Once free, she is thrown far from the STS. Stone panics, trying to contact Houston or Kowalski. Kowalski, who is wearing a thruster pack, suddenly appears and attaches her tether to him. He flies them back to the STS; on the way they find the engineer Shariff, his helmet smashed and his skull mostly open and empty. They find that the STS Explorer has been catastrophically damaged. The shuttle's interior has been ripped open by debris and the remainder of crew are dead. 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. Kowalski estimates they have 90 minutes before the debris field completes an orbit and threatens them again.With Stone's oxygen reserve running low, they float through space to the ISS. Kowalski asks Stone about her life back home and learns that her daughter died in a schoolyard accident. As they approach the slightly damaged ISS, they see that its crew has already evacuated in one of the Soyuz modules and that the parachute of the other Soyuz, designated TMA-14M, has...
