Lunar Evacuation System

Lunar Evacuation System Assembly (LESA) developed by the European Space Agency (ESA) is a pyramid-like structure designed to rescue an astronaut should he or she suffer an injury on the lunar surface.

How LESA Works?

  • Since Astronauts would be wearing heavy extravehicular activity (EVA) suit, it is impossible for a fellow crewmate to carry the injured astronaut over their shoulder while wearing an EVA suit
  • LESA will enable an astronaut to lift their crewmate into a mobile stretcher in less than 10 minutes for carrying them to the safety of a nearby pressurised lander.

ESA is currently testing the LESA under the sea since the rocky, sandy terrain and buoyant salt water along with the bottom of the ocean floor has much in common with the lunar surface.
