A description of the experiment and the performance
status is given in ESA's Erasmus Experiment Archive (EEA) and in addition a condensed account of the experiment's aim and foundation has been provided in ESA's Human Spaceflight Science Newsletter no.1, 2010. The experiment
needs 8-10 human test subjects for medical statistics reasons,
for it to be completed. The experiment tests two hypotheses that are based on
a more than two decades long research in understanding the reaction of the cardiovascular system to exposure to
microgravity. The responses that can be observed in Space in the areas of adjustment of blood pressure, resistance in
the circulation, tissue fluid filling and urine excretion, etc. do not fit completely with theories. Thus, the new theories
for how the observable reactions could be explained.
