The Comex-designed Gandolfi suit adapted for underwater Lunar gravity.
Training astronauts underwater is an effective way of getting used to the sensations of working in weightlessness for long periods.
The underwater training concept was extended by French deep-diving specialists Comex to simulate gravity on the Moon. Lunar gravity can be simulated by adjusting the astronaut’s buoyancy – our Moon has a sixth of the gravity we feel on Earth.
