ISRO Successfully Launched SSLV-D2: Small Satellite Launch Vehicle (SSLV) was launched by the Indian Space Research Organisation on a second demonstration mission to Low Earth Orbit on Friday. It has been designed to relieve the Polar Satellite Launch Vehicle (PSLV) of its responsibilities and serve the small satellite launch market.
SSLV launched from the Satish Dhawan Space Centre in Sriharikota for a 15-minute journey to Low Earth Orbit carrying three payloads weighing more than 350 kilogrammes. The mission’s principal cargo was the Earth Observation Satellite-07 (EOS-7). The launch vehicle also carried Janus-1 and AzaadiSAT-2 as rideshare payloads.

The three steps of SSLV performed as Isro had anticipated. However, all eyes were on the Velocity Trimming Module, the final step powered by liquid propulsion. After the three stages of the rocket separated, the VTM fired to generate the desired 450-kilometer circular orbit for satellite deployment. Following VTM’s orbital modifications, the three satellites were subsequently released into the desired orbit.
“We have a new rocket launcher. In its second try, SSLV has accurately placed satellites into orbit. Gratitude to each of the three satellite teams. The first flight of SSLV was narrowly missed due to a velocity deficiency. We have quickly analysed the issue, determined the corrective measure, and qualified the system “S. Somnath stated after ISRO Successfully Launched.
This was the second launch of Isro’s brand-new launch vehicle, following the failure of the initial demonstration flight. Launched in August of last year, the SSLV D1 mission failed to deliver the satellites into orbit, rendering them useless.
SSLV, according to Isro, is distinguished by its low cost, shorter turnaround time, versatility in hosting many satellites, potential for launch-on-demand, and minimal launch infrastructure needs.

The mission’s success signifies India’s long-awaited entrance into the multimillion-dollar small satellite launch industry. Customers from around the globe can utilise the SSLV to launch small satellites up to 500 kilometres above Earth.
