International Space Station — Research Lab
What happens in low earth orbit? What do the astronauts work on in their 90 minutes orbits?

Flying at 17,500 miles an hour they are studying physical science, physics, biology, and effects on the life of long term space flight. They observe the eyes, cardiovascular systems, and the bodies of some of the ISS astronauts.
The Station
From the front of the station that is manned by 15 different nations. There is a window on the port side that shows one of the robotic arms. Moving backward you find Node 2. This is the Kebo Module made by the Japanese. They do a lot of biology and life science as well as have an exercise space here. They are currently working on cells' attitudes in zero gravity in Petri dishes.
Continuing on, the European Space Agency’s Columbus Module.
Then you have the crew quarters. This is where the astronauts have their own sleeping bag looking areas. Because they are in zero gravity they sleep floating with their computer and other personnel items around their area.
The Destiny Lab is aft of the crew quarters. This is where they make their oxygen and water from urine, CO2, and condensate. They also have a treadmill with friction belts so they don’t float away.
The Unity Module holds the CWC, which is all the contained water for drinking, experiments, etc.
Next is the airlock that leads to the Russian side of the station.
This is where the Pressurized adapter/docking station is. This is where they store FCB.
Next is the docking compartment where the Soyuz and dragon attaches to the station.
The Progress Cargo Vehicle is near the docking area. This is where progress docks. It was not made to reenter the earth’s atmosphere so this is where they put trash and debris. It carries the supplies because they need a constant supply. “plus there was a need for maintenance items and scientific payloads that necessitated a dedicated cargo carrier. Such payloads were impractical to launch with passengers in the restricted space of a Soyuz,” ( Wikipedia).
Finally, you have the Service Module. This is the place they eat and get water. They can also exercise here.
