LESA or Lunar Evacuation System Assembly is a system to rescue astronauts in case of injury on lunar surface. Comment.

The Lunar Evacuation System Assembly developed by the European Space Agency is a structure shaped like a pyramid which is being aimed to rescue astronauts if they incur any injury on the lunar surface. LESA enables an astronaut to rescue a fellow who has fallen as their heavy extravehicular activity suits do not let the pick another person. LESA thus lets the fellow astronaut to shift his companion to a mobile stretcher in less than 10 minutes. LESA is being tested under sea as the rocky, salty and sandy terrain is much closer to lunar surface.
