In total, 21 flights were taken over Russian skies, with 15 zero-gravity parabolas per flight, making a total of about two hours and fifteen minutes in weightlessness.
But many of the theories describing how physics should work in weightlessness have not been tested in detail. 1 2 Next Page ».
It seems that not all cell types of the immune system are sensitive to reduced gravity: Extensive studies with natural killer cells in simulated weightlessness and in real microgravity on board the ISS revealed that neither cytotoxic effects nor interferon production is altered in microgravity [ 30].
