ISRO successfully launches third SSLV carrying earth observation satellite

Sriharikota, August 16 2024 : The Indian Space Research Organisation (ISRO) successfully launched its third and final development flight of the Small Satellite Launch Vehicle (SSLV) from Sriharikota on Friday morning. The mission carried the 175-kg Earth Observation Satellite, EOS-08, to space, marking a significant achievement in ISRO’s efforts to commercialize small satellite launches. The SSLV-D3 mission was pivotal as it was the last authorized development flight of the SSLV, which is designed to carry payloads of up to 500 kg into low Earth orbit. This vehicle, just 2 meters in diameter and 34 meters in length, is equipped with three solid-fuel stages and a liquid-fuel stage to correct velocity and accurately place small and micro-satellites into orbit.

ISRO announced the successful launch via a post on the social media platform X, confirming that the EOS-08 satellite was precisely placed into orbit. ISRO Chairman S. Somanath confirmed that the mission met all its objectives, with no deviations in the injection conditions. He further stated that the final orbit would be verified after tracking, but initial indications suggested that the satellite had been injected perfectly. This mission is seen as a stepping stone towards the commercialization of SSLV launches, with future missions set to be carried out by a private company selected by ISRO. New Space India Limited (NSIL), ISRO’s commercial arm, has already signed a memorandum of understanding to launch an Australian satellite aboard a privately-operated SSLV. This satellite, developed by Space Machines Company, is designed to repair other satellites in orbit.

The SSLV program had a rocky start, with the first development flight in August 2022 narrowly missing its target. However, the vehicle successfully inserted three satellites into a 450-km circular orbit in February 2023. The EOS-08 mission’s success solidifies ISRO’s position in the growing market for small satellite launches, as global demand for such vehicles continues to rise.
