4. What can you see in space?
Shuttle astronauts can see highways, airports, dams and even large vehicles from an Earth orbit that is about 135 miles (217 kilometers) high. Cities are clearly distinct from surrounding countryside, and that's true even from the higher perch of the International Space Station, which circles the planet at about 250 miles (400 kilometers) up.

6. How do astronauts sleep in space?
Since there's no gravity in space, astronauts can sleep vertically (standing up) as well as horizontally. In the space shuttle, astronauts often sleep in their seats or in sleeping bags attached to the wall. On the International Space Station, the astronauts sleep in a Habitation Module with sleeping bags attached to walls as well. All an astronaut really needs to sleep in space is to be tethered to something so he can't drift around.
