The weightlessness, so fascinating and exhilarating for the experimenter, nevertheless leads in a worrying way to the accelerated aging of the organism. During space missions, we observe in a few weeks or months muscle damaging, bone decalcification, and cardiovascular, immune, neurosensory alterations ... These disorders are similar to those that occurs with age on Earth, but at time scale relevant to years or decades. They impose astronauts to undertake a daily struggle to preserve their organism and remain operational.
