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 European Space Agency (ESA), an intergovernmental organisation of 22 member states dedicated to space exploration.
• LESA is a pyramid-like structure. It is designed in a way to be deployed just by a single astronaut in lunar gravity to rescue an incapacitated crew mate.
