The experiments in the Columbus space laboratory
In return for the space shuttle transport of Columbus into orbit, NASA has secured half of the available installation slots for science racks: HRF2 is one of them. It provides a device that can measure an astronaut’s lung function across a variety of parameters.
There is also a freezer that can be used, for example, to keep astronaut blood samples frozen before they are taken to ground medical teams for further analysis on one of the spacecraft returning from the ISS.
A centrifuge is also provided for this purpose: As in a biology laboratory, it is possible to separate blood components from one another by centrifugation, for example.
