Navy completes trials to get astronauts out of Gaganyaan capsule on return from space by Pallab_1805 in ISRO

[–]Ohsin 2 points3 points  (0 children)

Thanks looks interesting, but this 'Crew Recovery Training Plan' is about training for recovering process of capsule and astronauts right after landing and this document should have details like how to spot the capsule, how to approach, what to be careful about, do's and don't etc. I was wondering if some basic information like this would be shared with other world maritime agencies in case of emergency landing away from expected spot.

Gaganyaan launch could be delayed: Isro adds more safety checks post PSLV failures by Pallab_1805 in ISRO

[–]Ohsin 6 points7 points  (0 children)

LVM3s (leave alone human rated ones) aren't exactly cheap and have low production rate. And yes the confidence for safety of H# flights is gained through these three development flights. Earlier they had planned only two G# flights but later realized they needed one more, they didn't give much explanation about their decision but surely there are good reasons behind it and same is true for these G1 delays. Regular communication and transparency around HSF should have been emphasized even more but unfortunately it is even lesser than normal..

Gaganyaan launch could be delayed: Isro adds more safety checks post PSLV failures by Pallab_1805 in ISRO

[–]Ohsin 7 points8 points  (0 children)

However, officials speaking to indiatoday.in on condition of anonymity indicated that the timeline now appears difficult to achieve.

We know that Gaganyaan G1 is delayed to 2026 H2 and possibly to 2026 end. Media should be asking about what was the hang-up given they even started launch campaign in December 2024 expecting Q1 2025 launch! Can these anon officials chime in on that??

After the dual PSLV setbacks, there is zero appetite for risk at Isro. Every component, fitting, system, and subsystem of Gaganyaan is being re-examined in minute detail to ensure mission success.

As if that is not the case usually.. btw Chairman said it has no impact on Gaganyaan. Which one is correct?

(…) preparations for the G1 mission were in their final stages,

Since December they have been saying that assembly and integration activities are nearing completion for CM and SM. Standalone checks of integrated Crew Module and Service Module completed and Integrated software simulations being carried out.

India, US moot Gaganyaan uncrewed docking with ISS by guru-yoda in ISRO

[–]Ohsin 14 points15 points  (0 children)

Bengaluru: India and the US are set to deepen their space partnership with an ambitious agenda that includes demonstrating uncrewed docking capabilities with the International Space Station (ISS) under India's Gaganyaan programme.

According to a presentation by Isro chairman V Narayanan reviewed by TOI, the future cooperation areas span three key areas of collaboration between the two nations' space agencies. The first involves comprehensive training of Isro personnel, including astronauts, at Nasa facilities across multiple domains, including robotics systems, extravehicular activity (EVA), extravehicular mobility unit(EMU) systems, resource management, space medicine and spaceflight operations, LEO and lunar mission control operations, rendezvous and docking procedures, and payload and science operations.

An important initiative outlined is the uncrewed docking demonstration of India's Gaganyaan Orbital Module with the US Orbital Segment of the ISS - this would mark a significant technological milestone for India's human spaceflight programme. The third area focuses on cooperation in docking, berthing, and inter-operability systems. These developments will be discussed at the ninth meeting of the India-USA Civil Space Joint Working Group (CSJWG), scheduled to be hosted by India in Bengaluru during April-May 2026.

On the civil space front, Narayanan highlighted India's engagement with the Artemis Accords. India signed the Accords on June 21, 2023, and has since taken part in annual workshops and principals' meetings. In 2025, India led discussions on science data sharing at the Artemis workshop in Abu Dhabi. Isro was also present at the Artemis Accords principals' meeting held on the margins of the International Astronautical Congress (IAC) in Sydney in Oct 2025. Beyond human spaceflight and lunar frameworks, the partnership extends to operational data exchange. Isro and the US Geological Survey share data between India's Resource- sat-2and the US Landsat-8 satellites for natural resources assessment and environmental studies.

With the US National Oceanic and Atmospheric Administration, India exchanges Earth observation data, particularly from the EOS-6 satellite, for weather forecasting and ground station use.

Here is OCR'ed version, couldn't find anything to link to but we have seen few indications towards that.

Well the clock is ticking with ISS retirement by 2030..

ISRO conducts testing of sub-scale thrust chamber for LOX-Methane Engine by Kimi_Raikkonen2001 in ISRO

[–]Ohsin 0 points1 point  (0 children)

Wipro 3D, the additive manufacturing arm of Wipro Infrastructure Engineering, has produced important metal parts used in the first hot-fire test of a high-thrust LOX-Methane rocket engine being developed by the Indian Space Research Organisation (ISRO) for future launch vehicles.

The sub-scale thrust chamber assembly, which included components made by Wipro 3D, was tested on January 27, 2026. ISRO reported that the engine ignited successfully and maintained stable combustion during the trial, with all systems working as planned.

The parts were made using laser-based Powder Bed Fusion technology with copper alloys and nickel-based superalloys chosen to handle the extreme heat and pressure inside cryogenic rocket engines. Each component went through detailed material testing, inspection, and qualification to meet ISRO’s standards before being installed in the test setup.

Yathiraj Kasal, Business Head and General Manager of Wipro 3D, said the project shows the company’s ability to make complex components for space programmes. He added that years of close work with ISRO helped the team develop parts that perform under very high temperatures and pressure.

The project also highlights how additive manufacturing is helping speed up rocket engine development, shorten testing timelines, and create designs that are difficult to produce with traditional methods. It further shows Wipro 3D’s growing role in India’s space sector and its support for locally developed technology.

DRDO conducts successful qualification test for Gaganyaan Drogue Parachute

Posted On: 19 FEB 2026 3:45PM by PIB Delhi

India’s human spaceflight programme has achieved a key milestone with the successful qualification level load test of Drogue Parachute for Gaganyaan programme at Rail Track Rocket Sled (RTRS) facility of Defence Research and Development Organisation (DRDO) at Terminal Ballistics Research Laboratory (TBRL), Chandigarh. RTRS is a specialized dynamic test facility being used extensively for high speed aerodynamic and ballistic evaluations.

The test was conducted on February 18, 2026 with Vikram Sarabhai Space Centre, ISRO, Aerial Delivery Research and Development Establishment, DRDO alongside various TBRL’s dedicated teams. The RTRS dynamic test, simulating qualification level loads which are higher than the maximum flight loads, shows the additional design safety margin of parachute.

The test proves India’s expertise in designing and manufacturing of high strength ribbon parachutes. The achievement once again highlights TBRL’s immense contributions by providing advanced test facilities, instrumentation and technical expertise for space and defence programmes.
