India's Gaganyaan Program Achieves Milestone: Successful SMPS Hot Tests

ISRO announced the successful completion of two hot tests of the Gaganyaan Service Module Propulsion System (SMPS). The tests, lasting 30 and 100 seconds, validated the system configuration and successfully demonstrated the simultaneous operation of all Reaction Control System (RCS) thrusters and Liquid Apogee Motors (LAMs). This is a crucial step in the Gaganyaan human spaceflight program, aiming to demonstrate India's capability to launch a crewed spacecraft into low Earth orbit. ISRO plans a full-duration hot test shortly.
