India conducts another parachute drop test for its Gaganyaan manned capsule

India’s space agency ISRO today successfully completed its second helicopter drop test of a dummy capsule, testing the parachute release system that its Gaganyaan manned capsule will use on return to Earth.

In this test, a simulated Crew Module, weighing about 5.7 tonnes, that is equivalent to the mass of the Crew Module in the first uncrewed Gaganyaan mission (G1), was lifted by an Indian Air Force Chinook helicopter to an altitude of about 3km and released over a designated drop zone in sea, near to Sriharikota coast.

Ten parachutes of four types were deployed in a precise sequence during the descent of the Crew Module, gradually reducing the velocity for safe touchdown. Subsequently, the simulated Crew Module was successfully recovered in coordination with Indian Navy. The IADT-02 test validated the parachute-based deceleration systems in the Crew Module.

The manned mission is presently scheduled for early next year, after a series of unmanned orbital test flights are completed in ’26. This schedule is significantly later than ISRO’s original schedule. When the program was first proposed in 2018, ISRO said the manned mission would happen in 2022.

Genesis cover

On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.

 

The print edition can be purchased at Amazon or from any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.


The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
 

"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

    Reinventing the wheel. These systems can be purchased off-the-shelf from American space industry subcontractors.

  • In-house development is more of a national security deal, I think. However, an American helicopter introduced before I was born did the heavy lifting. I’m a little embarrassed for my Indian acquaintances: I look forward to congratulating them on crewed spaceflight.

    You want to develop in-house competency.

    Parachutes worry me more than heat-shields.

    I have heard it said that chutes are packed such that they are like blocks of wood.

    Those bloody choppers near Integrity could easily have gone all John Landis….

    Parachutes for one purpose are not necessarily correct for another. Mercury, Gemini, Apollo, Soyuz, Dragon, and Starliner all use different parachutes, because one size does not fit all, even when the “all” are similar sizes.

    Speaking of reinventing the wheel, one size does not even fit all Mars rovers. The similar-sized Curiosity and Perseverance use different wheels. Even on Earth, automobile wheels are different than railroad wheels, which are different than ox cart wheels.
