About LESA:
- Among other preparations for NASA's 2024 Moon mission (Artemis Mission), scientists are testing the Lunar Evacuation System Assembly or LESA device.
- It is developed by the European Space Agency (ESA), an intergovernmental organisation of 22 member states dedicated to space exploration.
- LESA is a pyramid-like structure which is designed in a way to be deployed just by a single astronaut in lunar gravity to rescue an incapacitated crewmate.
Need for such device and its significance:
- On a mission, astronauts wear Extravehicular Activities (EVA) suits that are bulky and heavy due to which they do not allow for a full range of movement.
- Thus while wearing an EVA suit, there is no way that an astronaut could carry their fallen crewmate over their shoulder.
- In order to rescue a fallen colleague, LESA can be operated just by a single astronaut thus ensuring a rapid and safe rescue.
- LESA can be transported like a golf caddy and placed close to the fallen astronaut, hence enabling an astronaut to lift their crewmate onto a mobile stretcher in less than 10 minutes, before carrying them to safety on a nearby pressurised lander.
