After the profitable Test Vehicle-D1 (TV-D1) mission on October 21, the Indian Space Research Organisation (ISRO) has lined up more check missions in the months forward for the Gaganyaan programme.
Upcoming tests embody the TV-D2 mission, the G-X unmanned orbital demonstration flight, an Integrated Air-Drop Test (IADT) and a Pad Abort Test, S. Unnikrishnan Nair, Director, Vikram Sarabhai Space Centre (VSSC), instructed The Hindu.
A crew module with service module will probably be used in the G-X mission. This unmanned mission, to be launched aboard a human-rated LVM3, can have ‘Vyommitra’ – the ‘female’ robotic astronaut designed and developed by the ISRO Inertial Systems Unit (IISU) – on board. In this mission, ISRO will put to check management techniques, a “reduced version” of the life help system for the crew, thermal safety techniques and the parachute techniques.

Meanwhile, the Test Vehicle (TV) improvement programme will proceed parallelly. TV-D2 would be the second of 4 tests deliberate for demonstrating in-flight abort functionality underneath completely different preliminary circumstances with respect to the launch car. Unlike TV-D1, TV-D2 may also have onboard a management system for re-orienting the angle of the crew module as soon as it separates.
The check car would be the similar, expendable model based mostly on the L40 strap-on of the multi-purpose car Geosynchronous Satellite Launch Vehicle (GSLV) used in TV-D1 mission. TV-D1 demonstrated the in-flight abort of the Crew Escape System (CES) at 1.2 Mach pace, which was adopted by the separation of the crew module and its restoration from the ocean.
At the identical time, ISRO can also be analyzing whether or not the TV-D1 crew module, recovered from the ocean after a parachute-assisted splash-down, may be reused for future tests. The area company is trying into this chance, Dr. Unnikrishnan Nair mentioned. The lead unit of ISRO for launch automobiles, VSSC was accountable for the structural design and manufacture of the unpressurised crew module used for the check.
As the module had come into contact with salt water, solely an in depth inspection can inform whether or not it may be reused and in what capability. ‘‘We are figuring out a plan to reuse it. We want to open and clear it and see what may be achieved. Efforts will probably be taken to divert it for the suitable check programme underneath Gaganyaan,” he mentioned.
