Flight and Space

The International Space Station (ISS) is important to space exploration because

• It can hold a very large crew (20+ people).

• It can be launched fully assembled from a launch pad on Earth.

• It is good for learning about the effects of microgravity and living in space.

How do astronauts get water when in space?

• They bring up all the water they will need.

• Astronauts get packages of water delivered by a rocket.

• They continue to filter water again and again.

• They don't get enough water and that explains why they float.

Why do astronauts have to exercise so much when in space?

• To keep their muscles strong because they are not using them to fight gravity.

• Because they have nothing better to do.

• So they can get their spine to stretch out so they come back to Earth taller.
