(1)Second Term – Exam 1. Duration: 55 Minutes. Date: April 25, 2019. Full Name: ____________________________ 1. Class: ________. A spacewalk is when an astronaut gets out of a vehicle while in space. Spacewalks usually last. between five and eight hours, depending on the job. Astronauts go on spacewalks to work outside their spacecraft, or to do science experiments. Spacewalks also let astronauts test new equipment. They can repair satellites or spacecraft without bringing them back to Earth to fix. 2. When astronauts go on spacewalks, they wear spacesuits to keep themselves safe. Inside their. spacesuits, astronauts have the oxygen they need to breathe and the water they need to drink. Astronauts put on their spacesuits several hours before a spacewalk. And they breathe pure oxygen for a few hours. Then, they leave the spacecraft through a special door called an airlock. That way the air inside the spacecraft is. 3. IS SE. preserved. When on a spacewalk, astronauts use safety tethers to stay close to their spacecraft.. Tethers are like ropes. One end is hooked to the spacewalker. The other end is connected to the vehicle. The safety tethers keep astronauts from floating away into space. Astronauts also use tethers to. 4. AN. keep tools from floating away.. Astronauts train for spacewalks in two ways. First, they go for a swim. Astronauts. practice spacewalks underwater in a large swimming pool called the Neutral Buoyancy. re. Laboratory, or NBL. It is near NASA's Johnson Space Center in Houston, Texas. The pool. ai. holds 6.2 million gallons of water. Second, astronauts practice for a spacewalk by using virtual. ol. reality. It is much like playing a video game. Astronauts wear a helmet with a video screen inside. They also wear special gloves. On the screen inside the helmet, they watch a video of. Sc. what they will see during a spacewalk. And with the help of the special gloves, astronauts can also see their movements with the video. The virtual reality simulation looks and feels just like a spacewalk..
