The "Movement in Low gravity environments" (MoLo) programme from ESA’s space medicine team at the European Astronaut Centre in Cologne, Germany, aims to test movements in simulated reduced gravity, called hypogravity, on Earth. A 17-metres refurbished ventilation shaft in ESA’s ground based facility “Locomotion On Other Planets” in Milan, Italy, was fitted with a bungee rope, allowing a person to do vertical jumps as high as six metres in simulated lunar gravity, and for the team to investigate the movement and its biomechanics.
