Gaganyaan's review panel to meet in March

Quote
A national review committee on Gaganyaan is slated to meet for the first time here on March 5 and 6 and comprehensively scan the contours of the first Indian human mission to space. The Indian Space Research Organisation (ISRO) wants to unveil the human mission's details to stakeholders from multiple agencies, and also keep the nation in the loop about the prestigious mission, K.Sivan, ISRO Chairman and Secretary, Department of Space, said. He added, "It should also give us the confidence that we are on the right track with such a humongous project."

Agreements and programmes planned with the Indian Air Force (IAF) and the Defence Research and Development Organisation (DRDO) will start taking shape from now on, Dr. Sivan told The Hindu. "Gaganyaan-related activities are in full swing," he said, under the newly formed Human Space Flight Centre (HSFC) and a dedicated project team.

Quote
Gaganyaan is slated to take place at a ‘near-Earth' distance of 400 km. Before that, two unmanned trial flights with human-friendly capsules are to be flown in 2020, carrying a few micro-gravity experiments. "In order to have three flight-ready finalists as crew, we need to give astronaut training to at least ten [eligible] persons," he said.

The astronauts will be mainly trained at the IAF's Institute of Aerospace Medicine in Bengaluru. The area of Environment Control and Life Support Systems (ELCSS) is said to be the most important for making the capsule habitable for astronauts. The life sciences labs of the DRDO work in this area.

Life support hardware: so DRDO would be designing this (with ISRO) and produce it in their facility to integrate the same later with capsule...

"The Indian Space Research Organisation has recently had a discussion with representatives from various armed forces in the country to select astronauts. “The process (of selecting astronauts) is already on and an announcement for selection will be made soon,” said K Sivan, Chairman, ISRO, here{AERO INDIA 2019- Bengaluru} on Monday."

Design changes may delay ISRO's manned space mission

Quote
Even as the Indian Space Research Organisation (ISRO) is pushing for completion of the human space programme by the end of 2021, design changes required for the project might delay it further, say scientists at Defence Research and Development Organisation (DRDO).

DRDO is involved in developing a few products for ISRO for the programme. "While the initial proposal for India's programme involved only two astronauts, the recent announcement indicates that three people will be involved in the programme. In order to accommodate one more person, several design adjustments will have to be made to ensure the success of the programme," a DRDO scientist, under the condition of anonymity, said.

Quote
Another scientist added that one of the products of DRDO that will be used by ISRO will be the parachute for decelerating the crew module in which the astronauts will fly. "While the initial design of this was for two people inside the crew, now adjustments have to be made to ensure that the parachute is compatible with the new weight of the crew module. Several adjustments, such as increasing the diameters of the parachutes used or adding a new parachute, have to be made to ensure the crew module lands safely," said a senior scientist at DRDO.

Other agencies involved in the programme will also have to alter the models they had developed for the human space programme in the past, which might result in slight delays in the implementation of the programme and its first flight. However, ISRO is confident of completing the programme by 2021. ISRO chairman K Sivan had recently questioned why India couldn't complete the manned space mission by 2021 in the 21st century, while Russia (or undivided USSR) had executed the same in four years in 1957.

ISRO Chairman has recently clarified that the GSLV MK-III to be used for the Indian Human Spaceflight Program will not have the semi-cryogenic stage,

Quote
Sivan said, "The first test of the advanced version of Mk III will take place in December 2020. With upgrade in Mk III, we will also have to upgrade the launchpad facility at Sriharikota. We have therefore issued a tender notice recently inviting quotations for infrastructure upgrades at the second launchpad."

However, the chairman clarified the rocket with the semicryogenic stage won't be used for the Gaganyaan mission. The current GSLV Mk III with L110 stage will only be used for the manned mission with some modifications.

Waitasec - the Dec 2020 test flight will use the kerolox engine, but the actual crewed flight will use existing hydrazine L110?

Shouldn't they just try to test the same launch stack all the way through, for man-rating purposes?

Man rating certification might be the reason regarding the first manned flight.

Sure, but it sounds like ISRO's doubling up or making use of HSF  budget to validate the semi-cryo booster. I guess they don't want to waste time on the semi-cryo development, or let it get side-tracked by Gaganyaan.

Isn't the statement made by ISRO chairman crystal clear that the advanced version of GSLV MK-III with the semi-cryogenic stage will not be used by the Gaganyaan Mission ? Because, by the time GSLV MK-III uses the semi-cryogenic stage, ISRO will not have enough time to test the advanced GSLV MK-III for the manned mission. According to me, GSLV MK-III needs at least another 5 successful launches ( apart from the 2 successful orbital mission, excluding the first sub-orbital missions ), before the first of the two unmanned mission being undertaken by ISRO.

Yeah, I get that - but they're using one of the Gaganyaan test flights to validate the kerolox/semi-cryo engine - that was my point. Shouldn't the test flights be flying the exact same stack that will be used for the actual crewed flight?

Anyway, I guess the Gaganyaan budget is fat enough to come in handy for other programs which aren't unrelated in the longer run.

Well that doesn't give me much confidence in the whole plan at all - using a more or less completely new rocket (*) for no crew tests and then back to the old one with crew? Three flights within a year and 1st with crew in less than 2 years time?

Looking at how the US companies are doing (also China, which took more or less sacrifice their own spaceflight industry's other projects in the 1990s to get people in space), my guess is that the plan will ultimately slip by years - the whole plan just screams rushed to me. Throttle back the pace and get Indian astronauts to the ISS (can't see why not with their long term aerospace co-operation with so many of the ISS partners) in the next 2-3 years in the interim might be a better solution.🤔

is it just me or the statement by this DRDO official does not make any sense!

ISRO's human spaceflight program planning has been in process for more than a decade. They got funding for developing "basic technologies" for the same even before PM Modi's announcement last August. That is why we saw LVM/ CARE module suborbital flight test and PAD ABORT test before the announcement. I am sure that they were planning all of this considering a crew of three from the very beginning.

What age range should astronaut candidates for the Gaganyaan mission fall into?

36-year old Wing Commander Abhinandan Varthaman of IAF showed a lot of courage and calm presence of mind in a dire situation. I would like to see his name put forward to be an astronaut candidate for Gaganyaan.



Let's make this happen!

Why? Russia and China went orbital on their first go.
