Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the primary research platform?International Space Station (ISS), a multinational collaborative project
2. What is the crew rotation cycle?Expeditions typically last approximately six months, with crew rotations occurring periodically
3. Why do scientists study things in microgravity on the ISS?In space, there is almost no gravity, so experiments can show how matter and biology behave differently than on Earth, revealing new information.
4. How do astronauts stay healthy during long stays on the ISS?They exercise every day on special treadmills and resistance machines to keep their bones, muscles, and hearts strong.

Microgravity: A condition where the force of gravity is significantly reduced, leading to apparent weightlessness and unique experimental opportunities.
Extravehicular Activity (EVA): Any space mission activity performed by an astronaut outside a spacecraft, involving specialized spacesuits and equipment.
Physiological Deconditioning: The adverse changes in the human body's systems (musculoskeletal, cardiovascular, etc.) resulting from prolonged exposure to microgravity.
