Ground experimental programme

Back to article

Loss of red blood cell mass, volume of blood plasma, and haemoglobin has been continuously observed in astronauts during space missions. This phenomenon has been termed “spatial anaemia” and the underlying mechanisms causing this are still not clear. This experiment aims to determine the degree of ‘stress’ that the red blood cells have undergone to bring about cell damage.

Biodosimetry in astronauts

Back to article

Multi-fluorescent chromosome map of a cell exposed to cosmic radiation. The Biodosimetry in astronauts experiment will analyse tissue samples taken before and after spaceflight to help clarify the the effect that space radiation has on DNA, and the role of the space environment in modifying the radiation sensitivity of the bodily system of organs and tissues, primarily the bone marrow, spleen, tonsils, and lymph nodes, involved in the production of blood.
