ISRO has successfully completed its first ground test of the solid motor for SOLVE, a test platform associated with India’s Gaganyaan human spaceflight programme. Multiple reports state that the solid motor is used to power SOLVE, which in turn supports validation of the Gaganyaan crew module’s parachute-based deceleration system. The testing is described as an initial, crucial step toward conducting integrated parachute tests under different conditions. One outlet notes that the test vehicle helps validate the parachute system for safe return of the crew module, while another characterizes the objective as testing deceleration performance across varying parameters. The SOLVE approach is also described as being adapted from PSLV-related technology, and it is intended to provide flexibility to simulate mission scenarios for upcoming validation flights. Collectively, the sources indicate that this ground test clears an early milestone in the development and validation campaign, and that further tests are expected to follow as ISRO prepares for uncrewed Gaganyaan flights.
