David Saint-Jacques: The part of Station that’s in the sunshine gets very, very warm, and the part that’s in the shadow gets very, very cold, and that changes all the time. But the engineers who designed the Space Station were very smart, and they used special materials and combinations of material for which it doesn’t matter, these big changes of temperature. And thanks to that, Station does not deform much. But it was a very important factor in the design of the Space Station.
