A European Space Agency astronaut and instructor recently reenacted Neil Armstrong and Buzz Aldrin's first-ever walk on the moon. They dubbed the Apollo 11 mission to the moon as `Apollo 11 under the Sea'. However, there was one major difference as they did not walk on the moon, but on the seafloor.

Officials have revealed that the mission was intended to start preparing ESA astronauts for spacewalks on the moon, asteroids and Mars. Clervoy has been a part of three missions. He has flow to the space in NASA's now-retired space shuttle.

Comex-designed Gandolfi spacewalk training suits were worn by the deep-sea explorers. The suits are similar to the Russian Orlan spacesuit.

The French deep-diving company Comex created moon-like conditions underwater. It was made possible by adjusting Clervoy and Stevenin's buoyancy to one-sixth of the gravity they would typically feel on Earth.

Hervé Stevenin, who is an astronaut instructor, gave training to the astronaut, Jean-François Clervoy. Instructions were given to Clervoy to imitate the roles of Neil Armstrong and Buzz Aldrin.

This training was conducted as part of the ESA's efforts to improve the European expertise in spacewalking under partial gravity. This has helped astronauts practice for future tripe to the moon and other celestial bodies.
