Successful Ground Test Boosts Gaganyaan’s Crew‑flight Timeline
India’s space agency ISRO has completed a successful test of a brand‑new motor destined for the Gaganyaan crewed mission, clearing a key hurdle ahead of the uncrewed flight.
On Thursday, scientists at the Satish Dhawan Space Centre fired up a brand‑new liquid‑propellant motor that will soon sit atop India’s first crewed spacecraft, Gaganyaan. The test, which ran for a little over a minute, was monitored by engineers, journalists and a few curious onlookers – the excitement in the control room was palpable.
What makes this motor special? It’s designed to give a quick, high‑thrust kick when the crew capsule needs to re‑orient or perform a precise orbital maneuver. In past ground trials, similar engines showed a bit of wobble; this time the data showed a clean, steady thrust curve, exactly as the design team had hoped.
ISRO’s chief, S. Somanath, praised the team’s effort, noting that “each successful test brings us a step closer to putting an Indian astronaut safely into space.” The motor’s performance not only validates the engineering calculations but also builds confidence ahead of the upcoming uncrewed Gaganyaan flight slated for later this year.
Beyond the headline numbers, the test also verified the motor’s integration with the spacecraft’s avionics. The onboard sensors talked to the ground stations without a hitch, confirming that the real‑time monitoring system can handle the rapid thrust changes expected during a manned mission.
With this milestone cleared, the focus now shifts to the final stages of vehicle integration and the upcoming hot‑test of the complete launch vehicle. If everything goes as planned, India could see its first crewed launch as early as 2025 – a moment many of us have been waiting for since the first Gaganyaan announcement.
