How Astronauts Work

Astronauts risk their lives in the pursuit of science. How does NASA know who can be an astronaut? And what do they do when they're not in space?

How Spacewalks Work

When astronauts talk moonwalking, they don't mean the Michael Jackson dance move. Spacewalks take an entire day of preparation -- and a 240-pound space suit.

Why do some people believe the moon landings were a hoax?

Some people say that the moon landings never happened at all. Is it true? And why all the conspiracy theories?

How Space Food Works

Space food has come a long way since Project Mercury's paste-filled tubes. Today's astronauts select menus that include everything from macaroni and cheese to brownies.

How RocketCam Works

This video camera hitches a ride on the space shuttle to provide ground control with a bird's-eye view of the launch. Could RocketCam have prevented the Columbia space shuttle tragedy?

How do spacecraft re-enter the Earth's atmosphere?

Blasting a spacecraft into space is one thing. Bringing it back in one piece is another. Spacecraft are likely to burn up into bits if they aren't specially insulated and designed for the ride.

How Space Camp Works

Kids from around the world flock to Huntsville, Ala., to attend Space Camp. What's so appealing about science class in the summer, and can a 40-year-old go to camp?

Why are there dozens of dead animals floating in space?

Neil Armstrong may have been the first man on the moon, but he wouldn't have gotten there without fruit flies, rhesus monkeys or a dog.

Project Mercury launched the first American into space. What went on behind the scenes of this historic mission?
