IAD technology successfully used by ISRO to land payloads on Mars and Venus

IAD technology successfully used by ISRO: The Inflatable Aerodynamic Decelerator (IAD), which ISRO says is a game-changer with numerous implications for future missions including to Mars and Venus, was successfully tested. Vikram Sarabhai Space Centre (VSSC), an ISRO division, successfully test-flew an IAD from Thumba Equatorial Rocket Launching Station on a “Rohini” sounding rocket (TERLS).

IAD technology: Key Points

• Scientists from India and beyond, as well as ISRO, frequently employ Rohini sounding rockets to fly demonstrations of new technologies.
• Along with the IAD, new components including a micro video imaging system that recorded the IAD’s bloom and flight, a small software defined radio telemetry transmitter, a MEMS (Micro-electromechanical systems)-based acoustic sensor, and a variety of new methodologies were all successfully flight tested.

About IAD technology:

• The IAD was first folded and stowed in the rocket’s cargo bay, according to the Indian Space Research Organisation, which has its headquarters in Bengaluru (ISRO).
• The IAD was inflated at an altitude of around 84 km, and the sounding rocket’s cargo dropped through the atmosphere on it.
• The Liquid Propulsion Systems Centre (LPSC) of ISRO designed the pneumatic inflation mechanism.
• The IAD has consistently decreased the payload’s velocity through aerodynamic drag while maintaining the expected trajectory.

• Founder of ISRO: Vikram Sarabhai
• ISRO founded year: August 15, 1969
