Do astronauts use their legs or feet during space walks?

Best Answers

They don't use their legs much. Their feet are often used for securing them to the robotic arm or against foot restraints on the vehicle. For this reason, the current spacesuit (the EMU) has soft booties. They aren't really shoes. They aren't designed for walking, and would fail miserably on the moon. read more

The Advanced Crew Escape Suit is the orange suit that astronauts wear during launch and landing of the space shuttle. This suit cannot be worn during spacewalks. Sometimes, NASA astronauts will wear the Russian Orlan spacesuit. This suit is the Russian version of the EMU and is used for spacewalks. Another Russian suit is the Sokol. read more

Astronauts may be able to walk on the moon faster than previously thought, a new study reports. The findings could help scientists design better spacesuits that could aid astronauts' exploration of the moon, Mars or asteroids, the researchers added. Movies of NASA's Apollo astronauts on the moon typically show them hopping instead of walking. read more
