The Indian House Analysis Group achieved a major milestone in its Gaganyaan program with the profitable completion of a high-altitude abort check for its crewed spacecraft.
TV-D1 — Check Automobile Abort Mission 1 — was an uncrewed check of the launch escape system for the Gaganyaan spacecraft, bringing India nearer to its purpose of independently sending astronauts to area as early as 2025. If profitable, it will make the South Asian nation the fourth unbiased nation able to such a feat, behind Russia, the USA and China.
Liftoff came about at 12:30 a.m. EDT (04:30 UTC) Oct. 21 on the First Launch Pad of the Satish Dhawan House Centre in Sriharikota, situated alongside the coast of the Bay of Bengal. Utilizing a modified liquid-fueled booster from the nation’s GSLV rocket, the flight aimed to check the abort capabilities of the crew escape system in high-altitude circumstances.
The entire launch stack with the booster and launch escape system was about 115 ft (35 meters) tall. The booster part was 64 ft (19.5 meters) tall and 6.9 ft (2.1 meters) large, whereas the crew escape system part was 51 ft (15.5 meters) tall and a few 13.3 ft (4.05 meters) large.
About 61 seconds into flight, at an altitude of about 7.4 miles (11.9 kilometers) whereas touring a little bit quicker than the pace of sound, the crew escape system was activated, pulling the Gaganyaan capsule away from the modified GSLV booster.
A number of seconds later, the crew module separated from the escape system tower. At that time it was at about 10.5 miles (16.9 kilometers) in altitude touring round 342 miles (550 kilometers) an hour.
Throughout the capsule’s descent, a drogue chute was deployed to sluggish and stabilize its descent earlier than the three most important parachutes had been deployed at round 1.6 miles (2.5 kilometers) above the Bay of Bengal.
Splashdown occurred roughly 10 minutes later earlier than being recovered by the Indian navy simply off the coast of Sriharikota.

The launch escape system is a tractor design, which means it pulls the capsule away from the rocket within the occasion of a failure. That is what’s used for Russia’s Soyuz, China’s Shenzhou and the USA’ Orion spacecraft, in addition to the Apollo and Mercury applications within the Nineteen Sixties and 70s. SpaceX’s Dragon and Boeing’s Starliner each make the most of a pusher system for aborts.
Gaganyaan is a time period derived from the Sanskrit phrases “gagana” which means celestial and “yana” which means craft. This “celestial craft” features a 11.5-foot (3.5-meter) diameter capsule that’s formed like a gumdrop, just like SpaceX’s first-generation Dragon spacecraft. The complete system, together with the service module, is predicted to be geared up with photo voltaic arrays for energy and weigh roughly 18,100 kilos (8,200 kilograms).
The Indian House Useful resource Group has been systematically testing the Gaganyaan spacecraft, with vital milestones reminiscent of a reentry check in December 2014 and a pad abort check in July 2018.
As early because the second half of 2024, India plans to ship the primary uncrewed Gaganyaan spacecraft into low Earth orbit to check its numerous techniques. A crewed flight is deliberate for someday in 2025 and is predicted to incorporate three Indian astronauts.
For full orbital missions, Gaganyaan will journey to area atop a human rated LVM3 rocket, which has to this point accomplished seven profitable uncrewed missions with no failures. This rocket has usually been used to ship communications satellites into geostationary orbit.
Lately, within the wake of India’s profitable robotic Chandrayaan-3 Moon touchdown, Indian Prime Minister Narendra Modi introduced a purpose to ship Indian astronauts to the Moon by 2040 after finishing a human-tended area station in low Earth orbit by 2035. Moreover, the nation has proven its dedication to worldwide area cooperation by signing the U.S.-led Artemis Accords, highlighting its intent to work collaboratively with different spacefaring nations.
