ISRO Completes Major Development Test of its Gaganyaan Parachute System
Gaganyaan_Parachute_System

It was an unusual morning for the residents of the small cantonment town of Babina on the outskirts of Jhansi as they saw two giant colourful parachutes descending through a foggy November sky. The parachutes later turned out to be the same parachutes that would help the astronauts of the country’s first human spaceflight return to earth safely after completing their mission in space.
On Friday, Vikram Sarabhai Space Centre, the lead centre for Gaganyaan activities conducted a major development test of its crew module deceleration system at the Babina Field Fire Range (BFFR) in the Jhansi district of Uttar Pradesh. The Integrated Main Parachute Airdrop Test, or IMAT, marks a significant milestone toward realizing the nation's ambitious Gaganyaan project.
The Gaganyaan deceleration system consists of three main parachutes, besides the smaller ACS, pilot, and drogue parachutes, to reduce the speed of the crew module to safe levels during its landing. Two of the three main chutes are sufficient to land the astronauts on earth, and the third is redundant. The IMAT test simulated the case when one main chute failed to open. The IMAT test is the first in a series of integrated parachute airdrop tests planned to simulate different failure conditions of the parachute system before it is deemed qualified to be used in the first human spaceflight mission.
In this test, a 5-ton dummy mass, equivalent to the crew module mass, was taken to an altitude of 2.5 kilometres and dropped using the Indian Air force’s IL-76 aircraft. Two small pyro-based mortar-deployed pilot parachutes then pulled the main parachutes. The main parachute sizes were initially restricted to a smaller area to reduce the opening shock. After 7 seconds, the pyro-based reefing line cutters cut the area restricting line, allowing the parachutes to inflate fully. The fully inflated main parachutes reduced the payload speed to a safe landing speed. The entire sequence lasted about 2-3 minutes as the scientists watched the different phases of the deployment sequence unfold with bated breath. There was loud cheer and applause as the payload mass landed softly on the ground and the gigantic parachutes collapsed.
The design and development of the parachute based deceleration system is a joint venture of Indian Space Research Organisation and the Defence Research and Development Organization. The overall system design, analytical simulations of parachute deployment and crew module descent under various conditions, the design and development of ordnance devices for parachute extraction and ejection, assembly/mechanical & electrical integration of deceleration system, it's instrumentation and avionics for conducting this drop tests are done by Vikram Sarabhai Space Centre (VSSC), Thiruvananthapuram, one of the leading R&D centre of ISRO.
Senior ISRO and DRDO scientists and air force officers were present to witness this crucial test. “Besides proving the calibre of the scientists of ISRO and DRDO, the test also demonstrated the active coordination between the country’s premier agencies, namely ISRO, DRDO, the Indian air force, and the Indian Army,” a senior official present during the test said.
The Gaganyaan parachute system consists of a total of 10 no. of parachutes. Each parachute's performance must be evaluated by complex testing methods using aircraft and helicopters. A total of five nos. of airdrop tests are planned at BFFR as part of the qualification of the Gaganyaan main parachute system. “The next test lined up at BFFR is to demonstrate the lead-lag deployment of clustered main parachutes using 5-tonne payload”, the space agency reported.

Isro working hard to make Gaganyaan a success in maiden attempt: Narayanan
MUMBAI: India will break a world space record by successfully accomplishing the country’s first human space flight programme — Gaganyaan — in its very first attempt, announced the director of Isro’s liquid propulsion systems centre, V Narayanan, at IIT Bombay’s Techfest on Friday.
Asia’s largest science and technology festival, which generally attracts about 1.75 lakh students from all over India, went offline after a Covid-induced two-year break on Friday. Narayanan said about 195 tests in various areas have to be conducted for the mission to succeed, of which 164 have been completed successfully so far.
While declining to provide a definite timeline for the mission, Narayanan said a key test which has succeeded is the one relating to the area of propulsion. “A lot of work has yet to be done and the team is working very hard,” he told the audience.
The mission envisages three astronauts spending about a fortnight in the low earth orbit before returning. Narayanan said it will take 16 minutes to reach the low earth orbit and the “deboosting to landing phase” will take 36 minutes. Experiments relating to “crew escape system” are currently underway for the safety of the crew members.
“Not only Isro, but the entire nation is working towards the success of this mission. It is a national mission,” he stated.
About Chandrayaan-2, India’s second mission to the moon, Narayanan said the orbiter which was originally planned for a one-year mission has been extended to seven years and has transmitted excellent high-resolution images. He said that it is equipped with the best optical instruments in the world. India’s next date with the moon will be next year, with the launch of Chandrayaan-3.
About future projects, he said Isro is working on an updated version of the Geo Synchronous Launch Vehicle Mark 3, which will increase its payload capacity from 4,000kg to 5,100kg.
Narayanan said Isro is also designing a semi-cryogenic engine and what is called the Next Gen Launch Vehicle. He said the next launch of the Small Satellite Launch Vehicle will be in January. The first launch of this new rocket on August 7 this year was not a complete success. Narayanan also announced that the next flight by a private space sector operator will take place “in a few weeks”.

Not Q1, it will definitely slip to Q3 2024
Why Q3 though? There are no other scheduled launches after M4.
Wat about cy3? Can we produce gslv mk3 more than 3 in a year
Current installed capacity allows production of 2 LVM3 in one year.

M3 (OneWeb second lot) is for this February and Chandryaan-3 is planned for August. Even if we have to assume that third rocket will be in production already from last year and stocks will be available, integration of a new LVM3 on launch pad after refurbishing it after launch of a previous LVM3 will consume many months pushing it to December or January. And after all that, G1 won't be a normal LVM3 rocket. It will be a human rated launcher with so many modifications.

This is the first time in years i heard the phrase pre pone used it's alllways postponed with goi
My brain auto corrected from preponed to postponed .. then I was confused how a postponement can be earlier and only then did I read the sentence again .. GOI projects have made me this way. :shock:

Delay in inflight abort tests...also in between CY-3 & G1, they have to launch atleast 2 GSLVs, one with INSAT-3DS & other with NISAR...both scheduled before mid 2024
It depends upon what they put on priority, satellites or Gaganyaan where entire episode had taken political colour in 2018. For 2021-2022, it was meant to earn some votes and praise for BJP, now for 2025-26, it will rather serve has symbolism of BJP's third consecutive term in India and a symbolism for world when Indian economy would have crossed $5 trillions.

2 separate GSLVs for IDRSS will anyway will be needed before G2 mission. NISAR is scheduled for December 2024, may slip to 2025 easily.

Total backlog here:
  1. TV-D1 & D2 (Independent L40 boosters), completion in 2023 at best.
  2. Two nos IDRSS satellites (requires 2 dedicated GSLV launches), 2023-24 launch window likely.
  3. Two nos full scale uncrewed test missions G1 & G2 (requires 2 dedicated LVM3-HR rockets), can be completed at mid or late 2024 at best.
And this is not unlikely that they may come up with more safety tests. Launching humans in space is a first for India, enough to fill ISRO with anxiety and fear of accident.
First human spaceflight is likely in 2025, can slip to 2026 if shit happens.

I don't think it's possible to launch G2 within six months after G1 launch, because after G1, they have to analyse the data & then make necessary corrections,it will take atleast 1 year to launch G2 after G1. So add 1 year gap between each launch

G1 - mid - late 2024
G2 - mid - late 2025
H1 - mid - late 2026

I disagree a bit on that. LEO isn't the Martian environment they don't know anything about.

The entire preparation program is about validation of working of systems and if system perform normal once, they will take no time in next. They will have to do another test as per conventional Indian criteria of two consecutive demonstrational successful launches before declaring the system operational.

That also explains why they have only given 6 months gaps between G1, G2 and H1. Once uncrewed launches of human rated LVM3 begin, consider this as beginning of conclusive stage of Indian human spaceflight program.

Check the Shenzhou program ....even though it's technologies are flight proven, they took one year gap between each flight,

I will still like to disagree. There is a huge tech gap between 1999 and 2023.
