Three Indian volunteers lay head-down for 7 days to simulate effects of space

Three Indian volunteers participated in a seven-day head-down tilt bed rest study to simulate the physiological effects of microgravity on the human body. The experiment, conducted by the Indian Space Research Organisation (ISRO) in collaboration with the Indian Institute of Science (IISc), took place at a facility in Bengaluru, India. The volunteers remained in a -6-degree head-down position for the entire duration to mimic fluid shifts and muscle atrophy experienced by astronauts in space. This research aims to inform countermeasures for future crewed missions, including India's Gaganyaan program. ISRO officials stated that the data collected will help design better exercise protocols and medical support for astronauts. The study is part of India's broader efforts to develop indigenous human spaceflight capabilities.

Global Impact

The study contributes to the global body of knowledge on space medicine, particularly for long-duration missions. Economically, it strengthens India's position in the space sector, potentially increasing its share of the $400 billion global space economy.
