5. Lifecycle of a microgravity experiment on the ISS

Generally speaking, life sciences experiments under microgravity rely on biological samples placed in dedicated space equipment known as Experimental Units (EU) , which are generally small in size. This bioreactor ensures the sample has a supply of culture medium, fixative (which interrupts and stabilises the experiment at a given moment and enables it to be preserved prior to carrying out further analyses), lighting and other necessary functions. To enhance sealing, each bioreactor may be enclosed individually in one or two containers, the whole being referred to in the field of space transport as a payload. The experiment is prepared in the laboratory or on the rocket launch pad a few hours prior to blast-off. The experimental units are then placed in an insulated transport bag, which is used to protect...
