European Space Agency (ESA) recently tested a device called Evacuation System Assembly (or LESA), which is designed to assist in astronaut rescue missions on the surface of Moon. As per ESA, it is world’s 1st device aimed to help future incapacitated astronauts.
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.
Feature: 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.
Need: On mission Astronauts wear Extravehicular Activities (EVA) suits that are bulky, 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.
Testing: NASA astronauts are testing LESA under sea. This is because, with its rocky, sandy terrain and warm salty water, the bottom of ocean floor bears much more similarity with lunar surface.
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 of a nearby pressurised lander.
Indian Space Research Organisation (ISRO) has opened the registration for recently launched Young Scientist Programme.
The programme also referred to as “YUva VIgyani KAryakram” (Yuvika) is aimed at imparting basic knowledge on Space Technology, Space Science and Space Applications to the younger ones with the intent of arousing their interest in the emerging areas of Space activities. The Yuvika programme aims to catch them young by providing residential training of around two weeks duration during the summer holidays.
Selection for the Programme
The selection for the programme is based on their performance from 8th Std marks. Those who have just finished 9th standard (in the academic year 2018-19) and waiting to join 10th standard (or those who have started 10th Std just now) are eligible for the programme and selection is based on both academic performance and extracurricular activities with special preference given to students from rural areas.
