India’s new SSLV rocket suffers “data loss” in maiden flight satellites’ standing unaccounted for – SpaceNews
SEOUL, South Korea — The Aug. 6 maiden flight of India’s newly produced Modest Satellite Launch Auto (SSLV) went awry with “some data loss” that occurred in the terminal stage of the mission.
India’s space company ISRO is examining details to know what took place and also checking the status of the two satellites deployed from the rocket.
In an unscheduled post-start announcement, ISRO chief S. Somanath claimed all stages had performed as envisioned, but “some details loss” experienced occurred in the last period of the flight. He did not give further facts. In a separate announcement, ISRO mentioned the rocket hit a dilemma “about 12 minutes into its flight,” which, based on the flight sequence announced ahead of liftoff, could be somewhere concerning the satellite injection module’s ignition and the very first satellite’s deployment.
The three-stage auto, able of sending up to 500 kilograms of payload to 500-kilometer low Earth orbit, lifted off at 11:48 p.m. Japanese Aug. 6 from Satish Dhawan House Centre’s start pad No.1, carrying an ISRO-constructed 135-kilogram earth observation satellite EOS-02 and an 8-kilogram cubesat AzaadiSAT, designed by Indian pupils.
Live footage showed the 34-meter rocket, adorned with India’s countrywide flag, soaring into the air with vivid yellow flames shooting out of its engines. While the rocket’s 3 phases employed sound gasoline, called hydroxyl-terminated polybutadiene, its satellite injection module, called Velocity Trimming Module (VTM), was driven by .05 tons of liquid fuel for the exact deployment of satellites.
Flight occasions noticed on the dwell-streamed display screen heralded that the rocket’s flight began effortlessly. The initially phase was separated about two minutes soon after liftoff as prepared, and the second phase did so 3.5 minutes afterwards. The 3rd stage’s separation took area 10.7 minutes after liftoff. The very last obtainable facts on the screen was that the injection module’s ignition started 10.8 minutes just after liftoff and “cutoff” promptly after. At just one place, the footage confirmed the EOS-02 satellite staying deployed from the module. The deployment of the other satellite, AzaadiSAT, was verified a couple of hrs later.
ISRO formulated SSLV with the goal of offering cheaper and far more adaptable access to space, compared to its two operational vehicles, the Polar Satellite Launch Auto (PSLV) and the Geosynchronous Satellite Launch Automobile (GSLV). To that conclude, SSLV was intended to be configured with a very simple modular interface, and the vehicle’s assembly can be accomplished horizontally and vertically. “We can do the assembly in a few or 4 times and launch in seven times,” The Times of India quoted a director of Satish Dhawan Place Centre as stating.
