The space shuttle carries astronauts back and forth between Earth and the International Space Station in orbit around our planet. What feature is necessary for the space shuttle to perform its function? The space shuttle must have-
|
|
sufficient mass to provide gravity equal to that of Earth.
|
|
|
powerful engines to escape the pull of Earth’s gravity.
|
|
|
enough food for the astronauts to eat for several years.
|
|
|
adequate space in which the astronauts can float freely.
|
Explanation:
Detailed explanation-1: -Without a tether, astronauts would float away due to the lack of gravity in space. Tethers add just enough weight to the astronaut to keep them in orbit.
Detailed explanation-2: -The suits provide the proper pressure for the body and supply astronauts with water to drink and oxygen to breathe. The spacesuit worn for spacewalks outside the International Space Station is called the extravehicular mobility unit, or EMU.
Detailed explanation-3: -Experiments can be placed on the outside of a spacecraft. This lets scientists learn how being in space affects different things. Spacewalks also let astronauts test new equipment. They can repair satellites or spacecraft that are in space.
