SOLAR SYSTEM

Detailed explanation-1: -The space station currently is the only place for performing research in long-duration microgravity.

Detailed explanation-2: -Yuri Gagarin from the Soviet Union was the first human in space. His vehicle, Vostok 1 circled Earth at a speed of 27, 400 kilometers per hour with the flight lasting 108 minutes.

Detailed explanation-3: -Crewed spacecraft are designed to support human life for the human spaceflight portion of the mission. Spacecraft for human spaceflight must have a human-rating certification as fit for purpose.

Detailed explanation-4: -The International Space Station is a large spacecraft in orbit around Earth. It serves as a home where crews of astronauts and cosmonauts live. The space station is also a unique science laboratory.

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: -The International Space Station is a platform for scientific research that requires one or more of the unusual conditions present in low Earth orbit (for example microgravity, (cosmic)-radiation and extreme temperatures).
