Astronauts aboard STS-133 are wrapping up a series of scheduled spacewalks, or extravehicular activities. When astronauts venture outside of their spacecraft, they need spacesuits to protect them from the solar radiation, the cold temperatures of space and fast-moving particles called micrometeoroids.Check out a great activity called Potato Astronaut: Spacesuit. Students investigate the effects of high-speed simulated micrometeoroid impacts and penetration depth. They also learn how layered materials protect astronauts. You will find the activity in the Lunar Nautics: Designing a Mission to Live and Work on the Moon Educator Guide on Page 133.
See additional activities in NEON. Register, log in, join the NASA Explorer Schools group, and find Lunar Nautics: Designing a Mission to Live and Work on the Moon. The activity is available in that forum.
