Integrated Parachute tests for Gaganyaan a success: ISRO, Pg11

Key Highlights:

• The Indian Space Research Organisation (ISRO) successfully conducted Integrated Parachute tests for the Gaganyaan mission's Crew Module.
• These tests validate the deceleration systems essential for the Crew Module's splashdown at sea.
• The tests, performed on July 3 at ISRO's Sriharikota center, involved the deployment of 10 parachutes.
• ISRO is developing a solid motor-based Sub-Orbital Launch Vehicle for Experiments (SOLVE) to facilitate these crucial validation trials.
• The SOLVE vehicle carries the Crew Module to an altitude of 10 to 17 km before separation for parachute deployment.

Detailed Insights:

• The Gaganyaan Mission is India's indigenous human spaceflight program, aiming to send a three-member crew to Low Earth Orbit (LEO) for a three-day mission and ensure their safe return to Earth.
• The Crew Module is a special, pressurized space vehicle designed to house astronauts and provide an Earth-like environment during take-off, space flights, and splashdowns.
• The parachute system for the Gaganyaan Crew Module comprises 10 parachutes of four types, deployed in a sequence to progressively reduce the module's descent velocity.
• This multi-stage deceleration system includes apex cover separation parachutes, drogue parachutes for stabilization, pilot parachutes, and three main parachutes for the final slowdown.
• The system is designed with redundancy, ensuring that even if one of the main parachutes fails, a safe landing can still be achieved.
• The SOLVE test rocket is a modified version of the Polar Satellite Launch Vehicle (PSLV) strap-on motors, adapted with a slow-burning propellant and a straight nozzle for specific test requirements.
• The successful completion of these tests is a critical step towards qualifying the parachute system for human spaceflight, ensuring the safety of astronauts during re-entry and splashdown.
• The development and testing of the parachute system involve collaboration between ISRO, the Defence Research and Development Organisation (DRDO), the Indian Air Force, and the Indian Army.

Scientific/Technical Concepts Involved:

• Gaganyaan Mission: India's ambitious human spaceflight program to demonstrate indigenous capability to send a crew to Low Earth Orbit.
• Crew Module: The habitable spacecraft designed to protect astronauts during spaceflight, re-entry, and splashdown.
• Deceleration Systems: Parachute-based mechanisms crucial for reducing the velocity of a spacecraft to ensure a safe landing or splashdown.
• Sub-Orbital Launch Vehicle for Experiments (SOLVE): A specialized test rocket developed to simulate re-entry conditions for validating spacecraft systems like parachutes.
