SOLAR SYSTEM

Detailed explanation-1: -Which of the following accommodations is required for an astronaut to directly communicate with another astronaut in space? A spacesuit includes a helmet, gloves, shoes, and a total body covering.

Detailed explanation-2: -While wearing the current space suits, astronauts wear a Communications Carrier Assembly (CCA), or “Snoopy Cap”-a fabric hat fitted with microphones in the ear area for listening and boom microphones in front of the mouth for speaking.

Detailed explanation-3: -Space is extremely cold and filled with dangerous radiation. Without protection, an astronaut would quickly die in space. Spacesuits are specially designed to protect astronauts from the cold, radiation and low pressure in space. They also provide air to breathe.

Detailed explanation-4: -Because there is nothing out in space (like an atmosphere), the sound waves from one astronaut’s whistling can’t travel over to the other astronaut’s ears. That’s why the astronauts use radios to communicate-even if they’re floating in space right next to each other!

Detailed explanation-5: -Above the 63, 000-foot threshold, humans must wear spacesuits that supply oxygen for breathing and that maintain a pressure around the body to keep body fluids in the liquid state. At this altitude the total air pressure is no longer sufficient to keep body fluids from boiling.

Detailed explanation-6: -Spacewalkers must wear pressurized spacesuits in order to work in space. These suits have pressures signifi-cantly lower than [the] ambient cabin pressure of a spacecraft.
