1st Sep 2022
2nd Sep 2022
3rd Sep 2022
4th Sep 2022

Correct Answer : Option (C) - 3rd Sep 2022

The Indian Space Research Organisation (ISRO) has successfully tested a technology that could aid cost-effective recovery of spent rocket stages and safely land payloads on other planets.
The Inflatable Aerodynamic Decelerator (IAD) was designed, developed and successfully test-flown by ISRO's Vikram Sarabhai Space Centre (VSSC).
What is IAD?

* The IAD was successfully test flown in Rohini-300 (RH300 Mk II) sounding rocket from Thumba Equatorial Rocket Launching Station (TERLS) here on Saturday(3rd Sep 2022).
* Rohini sounding rockets are routinely used for flight demonstration of new technologies being developed by ISRO as well as by scientists from India and abroad.
* The IAD serves to decelerate an object plunging down through the atmosphere.
* The IAD was initially folded and kept inside the payload bay of the rocket. At around 84 km altitude, the IAD was inflated and it descended through the atmosphere with the payload part of a sounding rocket.
* The IAD has systematically reduced the velocity of the payload through aerodynamic drag and followed the predicted trajectory.
* The force on an object that resists its motion through a fluid is called drag. When the fluid is a gas like air, it is called aerodynamic drag or air resistance.
Significance : The IAD has huge potential in a variety of space applications like recovery of spent stages of rocket, for landing payloads on to Mars or Venus and in making space habitat for human space flight missions..
