SOLAR SYSTEM

Detailed explanation-1: -For 20 years, the astronauts aboard the International Space Station have conducted science in a way that cannot be done anywhere else. Orbiting about 250 miles above our planet, the space station is the only laboratory available for long-duration microgravity research.

Detailed explanation-2: -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-3: -Astronauts also conduct research in space to better understand how fluids behave. Studying fluid dynamics in a gravity-free environment can help with the development of everything from medical devices to heat transfer systems.
