Testing Parachute Deployments for India's GAGANYAAN Mission



  Aug 16, 2023

GAGANYAAN Mission: Parachute Deployment Tests


What is GAGANYAAN Mission?

GAGANYAAN Mission is India's ambitious human spaceflight program aimed at sending astronauts into space. It aims to demonstrate India's capability to launch humans into space, conduct scientific experiments, and return the crew safely.
 

What are Parachute Deployment Tests?

Parachute deployment tests are crucial trials conducted to ensure the safe landing of astronauts during their return journey to Earth. These tests involve deploying drogue parachutes, which play a pivotal role in stabilizing the crew module and reducing its velocity as it re-enters Earth's atmosphere.
 

When Were the Tests Conducted?

The parachute deployment tests were carried out from August 8 to 10 by the Indian Space Research Organisation (ISRO) team.
 

Where Were the Tests Conducted?

The tests were conducted at the Vikram Sarabhai Space Centre (VSSC) using the Rail Track Rocket Sled (RTRS) facility of the Terminal Ballistics Research Laboratory in Chandigarh.
 

What Are Drogue Parachutes?

Drogue parachutes are specialized parachutes that are designed to deploy and slow down the descent of a spacecraft or crew module during re-entry into the Earth's atmosphere. They help stabilize the module and reduce its speed, making the landing safer for astronauts.
 

Why Are Parachute Tests Important for GAGANYAAN?

Parachute tests are critical for ensuring the safety of astronauts returning from space. The successful deployment of drogue parachutes is essential to slow down and stabilize the crew module during re-entry, allowing for a controlled and safe landing in the designated area.
 

What Were the Variations in Tests?

The ISRO team conducted three different variations of tests:
 
• Simulated the maximum reefed load: This marked a significant achievement by introducing the concept of reefing (controlled deployment) in a mortar-deployed parachute in India.
 
• Emulated the maximum disreefed load: This test evaluated the performance of the parachute under maximum load conditions.
 
• Showcased deployment under maximum angle of attack: This test replicated the conditions of the Crew Module's maximum angle of attack during its mission.

How Do These Tests Benefit the Mission?

The successful parachute deployment tests contribute to the overall success of the GAGANYAAN Mission. By ensuring that the parachutes perform as expected, ISRO can guarantee the safety of the returning crew and the effectiveness of the landing process.
 

What's the Significance of the GAGANYAAN Mission?

The GAGANYAAN Mission is a significant achievement for India's space program, showcasing the nation's capability to conduct human spaceflight. It marks a step forward in space exploration and research, demonstrating India's technological prowess in sending humans beyond Earth's atmosphere.
