KIDS TRIVIA

Detailed explanation-1: -Spacewalks let astronauts work outside their spacecraft while still in space. Astronauts can do science experiments on a spacewalk. Experiments can be placed on the outside of a spacecraft. This lets scientists learn how being in space affects different things.

Detailed explanation-2: -Spacewalks are often referred to as EVAs, or extravehicular activities. The first spacewalk by an American astronaut was conducted by NASA astronaut Ed White on June 3, 1965.

Detailed explanation-3: -The two oxygen tanks allow a maximum of between 6.5 and 8.5 hours outside in space, before which astronauts will need to refill the tanks. If an astronaut was lost in space with no way to return, this would be their downfall. They would eventually die of hypoxia. Without a suit, however, death would arrive much faster.
