The Indian Area Analysis Group achieved a big milestone in its Gaganyaan program with the profitable completion of a high-altitude abort check for its crewed spacecraft.
TV-D1 — Test Vehicle Abort Mission 1 — was an uncrewed check of the launch escape system for the Gaganyaan spacecraft, bringing India nearer to its objective of independently sending astronauts to area as early as 2025. If profitable, it might make the South Asian nation the fourth impartial nation able to such a feat, behind Russia, the US 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 Area 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 bit sooner 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.
Through the capsule’s descent, a drogue chute was deployed to sluggish and stabilize its descent earlier than the three important parachutes have 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 US’ Orion spacecraft, in addition to the Apollo and Mercury packages within the 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, much like SpaceX’s first-generation Dragon spacecraft. The complete system, together with the service module, is anticipated to be geared up with photo voltaic arrays for energy and weigh roughly 18,100 kilos (8,200 kilograms).
The Indian Area Useful resource Group has been systematically testing the Gaganyaan spacecraft, with vital milestones akin to 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 varied methods. A crewed flight is deliberate for someday in 2025 and is anticipated to incorporate three Indian astronauts.
For full orbital missions, Gaganyaan will journey to area atop a human rated LVM3 rocket, which has to date accomplished seven profitable uncrewed missions with no failures. This rocket has typically been used to ship communications satellites into geostationary orbit.
Just lately, within the wake of India’s profitable robotic Chandrayaan-3 Moon touchdown, Indian Prime Minister Narendra Modi introduced a objective 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.
