Witten, Germany (DLR PR) — The first tickets have already been sold to space tourists – the passengers, however, will not be as fit or healthy as astronauts, but rather people with greatly varying health conditions. This is why scientists at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) and physicians from Witten/Herdecke University have come together to analyse the prevalent risks in a pilot study. Using a long-arm centrifuge, they subject participants to 15 minutes of the forces that space tourists would encounter during takeoff and landing. The aim of the study is to determine the influence of increased gravity on blood coagulation.
