The Small Satellite Launch Vehicle (SSLV) is a small-lift launch vehicle developed by the Indian Space Research Organisation (ISRO) to deliver 500 kg (1,100 lb) payload to low Earth orbit (500 km (310 mi)) or 300 kg (660 lb) payload to Sun-synchronous orbit (500 km (310 mi)).[7] The rocket supports multi-orbital drop-offs capability for small satellites.[12][13][14]
The maiden flight SSLV-D1 was conducted from First Launch Pad on 7 August 2022,[9][15] however, the payload failed to reach the intended orbit.[16] The second flight SSLV-D2 was successful in delivering payload into orbit on 10 February 2023.[17]
SSLV is made keeping low cost, low turnaround time in mind with launch-on-demand flexibility under minimal infrastructure requirements. It is capable of carrying multiple satellites.[18] Once SSLV is operational, NewSpace India Limited (NSIL) and a group of Indian companies will manage the mass production and launch activities.[19][20][21]
