Why in news?
The Indian Space Research Organisation (ISRO) just declared that it has successfully demonstrated the new technology with Inflatable Aerodynamic Decelerator (IAD).
Key Facts
- IAD is a method applied to a payload for atmospheric entry.
- The inflatable aerodynamic decelerator is composed of an inflated envelope and an inflatant.
- It decelerates the lander as it inflates like a balloon as it enters the atmosphere.
- The inflatant is made to fill the inflatable envelope to the point where it surrounds the payload intended to enter a planet’s or satellite’s atmosphere and creates aerodynamic forces that slow it down.
- IAD is intended to enhance drag as soon as a spacecraft enters the atmosphere of any planetary body, including Earth, Mars, or even the Moon.
- A closed, gas-pressured body keeps it in shape, and the inflatant gas is also produced internally.
- In certain variations, ram air or both are used.
- Supersonic and hypersonic versions of the technology have previously undergone successful testing by some space agencies, including NASA.
- The IAD will help ISRO in performing many space tasks effectively including recovery of spent stages of rockets, for landing payloads on missions to other planetary bodies.
