The Space Shuttle (1981-2011) is a partially reusable rocket with a 42 m long orbiter, 2 SRBs and a tank that supplies the 3 main engines. In orbit, the OMS engines overtake. But, if the Space Shuttle's crew disappeared?
1 second after people: The Shuttle is headed for the ISS. It sends information that will be received by supercomputers, as long as the electrical power is on.
2 hours after people: The Shuttle crashes into the ISS, destroying and slicing the ISS into two halves. The fuel explodes.
1 day after people: The electrical power in most of cities fail, but Los Angeles is a light in the night.
5 days after people: The debris of the Shuttle start to hit other satellites, including the Hubble by debris thrown into higher orbits.
1 month after people: There is a problem: small creatures are blocking the way to turbines. With them being blocked, Hoover Dam's generators overheat and automatically shut down.
1 year after people: The debris now start to affect GPS satellites, which are otherwise in good condition. When even the smallest debris piece hits GPS satellites, they shut down to a safe mode.
20 years after people: ISS burns up when it's orbit reaches 80 x 110 km.
10,000 years after people: The debris of satellites continue to multiply.
Forever: The debris that left the Solar System are sucked by black holes, and these then evaporate. The ones that stayed near Earth's orbit got engulfed by the Sun, along with Earth, Mercury and Venus.
10^100 years after people: The supermassive black holes evaporate, leaving only subatomic particles left.
