Question

what is a spacewalk? (from what is a spacewalk? by nasa) astronauts go on spacewalks for many reasons. spacewalks allow astronauts to work outside their spacecraft while still in space. one job astronauts do on a spacewalk is science experiments. experiments can be attached to the outside of a spacecraft to see how the space environment affects different things. astronauts place the experiments outside their spacecraft during a spacewalk. they go back outside to get the experiments when the tests are over. astronauts also can test new equipment and make repairs to satellites or to their spacecraft while in orbit. by going on spacewalks, astronauts can repair equipment that might otherwise have to be brought back to earth for repair. what is the main reason it is important for astronauts to go on spacewalks? 1. spacewalks let astronauts extend their time on their spacecraft and in space. 2. spacewalks allow astronauts to conduct research and repair their spacecraft. 3. spacewalks help astronauts learn how long they can endure being outside their spacecraft. 4. spacewalks prepare astronauts for different situations like having to leave their spacecraft.

Explanation:

The text describes that spacewalks allow astronauts to conduct research, repair spacecraft, test new equipment, and perform experiments outside the spacecraft while in orbit. This helps with extending time in space and preparing for different situations. The key - function is to enable tasks that cannot be done from inside the spacecraft like repairs and experiments.

Answer:

1. Spacewalks allow astronauts to conduct research and repair their spacecraft.
