SOLAR SYSTEM

Detailed explanation-1: -An orbiting laboratory provides researchers with the unique features of low-Earth orbit (LEO): long-duration microgravity, exposure to space, and a unique perspective on our planet. These attributes enable scientists to conduct innovative experiments that cannot be done anywhere else.

Detailed explanation-2: -The space station has made it possible for people to have an ongoing presence in space. Human beings have been living in space every day since the first crew arrived. The space station’s laboratories allow crew members to do research that could not be done anywhere else.

Detailed explanation-3: -Throughout the more than 20 years of the ISS program researchers aboard the ISS and on the ground have examined aerosols, ozone, water vapor, and oxides in Earth’s atmosphere, as well as the Sun, cosmic rays, cosmic dust, antimatter, and dark matter in the universe.

Detailed explanation-4: -The living and working space in the station is larger than a six-bedroom house (and has six sleeping quarters, two bathrooms, a gym, and a 360-degree view bay window). To mitigate the loss of muscle and bone mass in the human body in microgravity, the astronauts work out at least two hours a day.

Detailed explanation-5: -Physical Science The space station provides the only place to study long-term physical effects in the absence of gravity. This unique microgravity environment allows different physical properties to dominate systems, and these have been harnessed for a wide variety of physical sciences.

Detailed explanation-6: -In space, astronauts live in a very small space. They have to keep their area clean in space just like we do on Earth. In space, the astronauts wipe the walls, floors, and windows to keep them clean. They use a soap that kills germs.
