ISRO Successfully Demonstrates "Inflatable Aerodynamic Decelerator" (IAD).

Science & Technology | Dated: 17 Dec 2025

The Indian Space Research Organisation (ISRO) successfully demonstrated the "Inflatable Aerodynamic Decelerator" (IAD) technology during a sounding rocket mission from Thumba. The IAD is a game-changer for future planetary missions (like Mars and Venus) and spent stage recovery, as it helps in slowing down payloads entering an atmosphere.

🎯 Key Highlights:

  • The IAD was folded and stowed inside the rocket's payload bay and inflated at an altitude of 84 km.
  • It successfully reduced the velocity of the payload through aerodynamic drag.
  • This technology will enable carrying heavier payloads to other planets.

💡 Other Important Facts:

  • Technology: Inflatable Aerodynamic Decelerator (IAD).
  • Purpose: Payload Deceleration/Recovery.
  • Launch Site: Thumba, Kerala.
