ISRO Successfully Tests Gaganyaan Crew Module Separation Ahead of G1 Mission
ISRO announced the completion of separation tests between the crew module and the service module for the Gaganyaan program, supporting the first uncrewed mission (G1) targeted for 2026.
The Indian Space Research Organisation (ISRO) announced the completion of separation tests of the crew module from the service module as part of the crewed Gaganyaan program at the Vikram Sarabhai Space Centre, according to the organisation's website.
ISRO explained that the tests used a configured setup simulating a full separation and severing of connections between the two modules, verifying design adequacy and the systems' shock tolerance capability, including electronics, inertial navigation, thermal protection shielding, and chemical separation systems.
The organisation stated that these results support the program's first uncrewed mission (G1), targeted for 2026, serving as a preparatory step prior to sending astronauts into space.
The Gaganyaan program represents India's ambitious effort to develop a national capability to send humans into orbit, following previous successes in satellite launches and uncrewed missions.
