Indian astronauts complete initial training for ISRO-NASA ISS mission​

Group Captain Shubhanshu Shukla (Prime) and Group Captain Prasanth Balakrishnan Nair (Backup) have completed the initial training phase for the Axiom-4 mission to the ISS.​

The first phase of their training included mission orientations, ground facility tours, and SpaceX suit fittings. They also familiarized themselves with space food options, the SpaceX Dragon spacecraft, and key systems onboard the ISS. Notably, the training also covered emergency preparedness, including medical emergencies, and operational routines such as space photography and communication protocols.

Looking ahead, the astronauts will continue their preparation, focusing on the US Orbital Segment of the ISS and scientific research in microgravity. They will also train in various mission scenarios aboard the SpaceX Dragon spacecraft.

In August, Science and Technology Minister Jitendra Singh indicated that an Indian astronaut could be aboard the ISS by April next year, marking a significant milestone in the ISRO-NASA partnership.

If the indigenous space project estimated to cost Rs 90 billion succeeds, India will become only the fourth country to send a human into space after the Soviet Union, the US and China.

"We have been working on the Gaganyaan project for the last four years. Our rocket is completely ready. The (first uncrewed test flight) launch is scheduled for early next year. We wanted to do it in December this year but due to technical difficulties, it is slightly getting extended."

The ISRO Chairman said three other launches will take place before the crewed flight towards the end of 2026. "Under the first launch, we will put a robot named Vyommitra inside. That launch will take place early next year. We will then have two more launches of similar nature. Once all the three launches are successful, we will have the crewed mission. All the astronauts are ready. We aim to launch Gaganyaan by the end of 2026," he said.

Gaganyaan Mission Likely To Be Launched By 2026-End: ISRO Chairman

The Gaganyaan project seeks to demonstrate India's human spaceflight capability by launching astronauts to an orbit 400 kilometres above the Earth for a three-day mission.

So 2027 or 2028 at worse?

Yep.
Talking realistically, first launch of Indian Orbital Station wont also come before 2035, Chandrayaan-4 too will happen after 2030.

Such techs need time for maiden attempts.

So 2027 or 2028 at worse?

2031-32 for H1 flight

Give atleast 2 years between each flight
G1 in late 2025- early 2026, don't believe them (it won't fly in early 2025)
G2 in 2027-28
G3 in 2029-30
H1 in 2031-32

That too if everything goes well

Yep CY-4 will be after 2030 mainly because of delay in semicryo engine & 1st launch of NGLV will be after 2036 only, don't expect it before 2035 & crewed moon landing after 2050, definitely not before it

SSLV was supposed to be launched in 2019, but it flew in 2022

Even for SSLV they took 3 years delay, don't expect NGLV to come by 2032

In case of Chandrayaan-4, development and testing of ascender module will consume multiple years.

Ascender is not that complex as you think it is , SCE-200 is the reason for delay not Ascender

India can and will launch early, if project to indigenously master life support systems fail by 2025, India will plug and play from Russians.

Wont be delayed beyond Jan 2027

As far as I can remember, India initiated the semi-cryogenic engine program
around 2005 as Project Jasmine, in collaboration with Yuzhmash of Ukraine. It is almost 2025, and we still don't have a working RP1-LOX engine. Now compare that with SpaceX which in 2005 was a 2-year-old start-up company.Today it's a 350 billion $ company that has built the world's biggest rocket with a payload capacity of 150,000 kg.

SpaceX happened in US which is literally the Space Superpower. They hired engineers and labor from NASA, Boeing and many other American space companies. They had funding like no one else that time.​

SCE-200 is unrelated to Chandrayaan-4. It won't use LVM3-SC. Chandryaan-4 regardless is one of priority projects like Gaganyaan but ascender module would undergo rigorous testing before mission execution. Like Chandrayaan-2 lander trials took 3-4 years alone.

SpaceX is essentially NASA's B team since spending public money on space is no longer viable in US.

Unrelated comparison.

Russian ECLSS was their 1st option, They choose to develop indigenous ECLSS because Russian system was incompatible

It will launch only after 2030 wait & watch

Merlin-1D which is used in Falcon-9 was developed ever before SpaceX was born

Check the latest presentations, LVM-3SC it is, total weight of all 5 modules is 9.2 tons, i.e 4.6ton each launch ,cannot be launched by current LVM-3 even with C32 stage replacing the old C25 stage

They chose to develop but Russian option was and is always there, integrations are complex but not difficult than building own life support systems

There's no going back to Russian system now. ISRO already knee deep into the R&D of ECLSS & a subscale engineering model of it will be flying in upcoming G1 flight. Going back to integrate Russian ECLSS will only add more delays to the program because you have to redesign & qualify the interiors of CM & SM

Better to take time rather than using other country system.

Surely the day will be best of my life when h1 will happen. But i really want to see indian aero engines in sky operational.
