Which of the following statements regarding the SSLV-D2 mission is/are correct?
Statement 1: SSLV-D2 placed EOS-07, Janus-1, and AzaadiSAT-2 into a 450 km circular orbit, but the launch vehicle did not use an all-liquid three-stage propulsion system.
Statement 2: SSLV-D2 demonstrated quick deployment capability with a short turnaround time and minimal ground infrastructure requirements.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. Both Statements 1 and 2 are correct.
Both statements are correct.
SSLV-D2 successfully placed EOS-07, Janus-1, and AzaadiSAT-2 into a 450 km circular orbit, and unlike the statement in older misconceptions, SSLV does not use an all-liquid propulsion system. It actually uses a three-stage solid propulsion system with a liquid-based velocity trimming module, making Statement 1 accurate.
Statement 2 is also correct because SSLV was designed by ISRO as a low-cost, rapid-launch vehicle capable of quick integration and minimal ground infrastructure. This makes it ideal for small satellite missions and frequent launch cycles. SSLV’s design philosophy focuses on flexibility, faster assembly, and reduced operational complexity, which the D2 mission clearly showcased.
