What else has gone wrong in space?
In case you missed it... two astronauts stuck in space for more than nine months have finally returned to Earth.
Butch Wilmore and Suni Williams first blasted off to the ISS on 5 June, expecting to be up there for just eight days.
However, their problem-plagued Boeing Starliner posed too much of a risk for them to return to Earth, and they've been waiting to come home since then.
Although nine months is a long time to be in orbit, the pair aren't alone in facing extraordinary circumstances in space.
