SOLAR SYSTEM

Detailed explanation-1: -NASA astronauts wear white suits, since white is the color that reflects the most sunlight in space, and protects them from cancer-causing solar radiation.

Detailed explanation-2: -The suits protect astronauts from getting too hot or cold. Spacesuits also give astronauts oxygen to breathe while they are working in space. The suits hold water to drink. They also keep astronauts from getting hurt by space dust.

Detailed explanation-3: -Aluminized polymer insulation layers maintain a comfortable thermal environment for the astronaut by reflecting the Sun’s energy out when in sunlight and the astronaut’s body heat in the suit when in shade.

Detailed explanation-4: -To cope with the extremes of temperature, most space suits are heavily insulated with layers of fabric (Neoprene, Gore-Tex, Dacron) and covered with reflective outer layers (Mylar or white fabric) to reflect sunlight.

Detailed explanation-5: -Cooling Garment Chilled water flows through the tubes near the spacewalker’s skin to regulate body temperature and remove extra heat during the spacewalk, which typically lasts multiple hours. Vents in the garment draw sweat away from the astronaut’s body and help with circulation inside the spacesuit garment.

Detailed explanation-6: -The formal name for the spacesuit used on the space shuttle and International Space Station is the Extravehicular Mobility Unit, or EMU. “Extravehicular” means outside of the vehicle or spacecraft. “Mobility” means that the astronaut can move around in the suit.
