RAS question
The Small Satellite Launch Vehicle (SSLV) developed by ISRO is designed to:
Correct answer: (A) Provide on-demand launches for small satellites up to 500 kg to LEO.
ISRO's Small Satellite Launch Vehicle is designed to provide launch-on-demand access for small satellites up to 500 kg to Low Earth Orbit.
Explanation
SSLV is meant for the small-satellite segment, not for replacing India's larger launch vehicles. The ISRO mission page describes it as a new small satellite launch vehicle developed to serve satellites up to 500 kg to Low Earth Orbit on a launch-on-demand basis. SSLV offers low-cost, on-demand launches for small satellites, with capability up to 500 kg to LEO and 300 kg to SSO. ISRO also notes that SSLV can launch mini, micro, or nanosatellites in the 10 to 500 kg class and offers low turn-around time, flexibility for multiple satellites, and minimal launch infrastructure. Option A captures its purpose precisely.
Why the other options are wrong
- (B) SSLV complements India's launch-vehicle range for small, on-demand payloads; it is not meant to replace PSLV completely.
- (C) A payload of over 5 tonnes is outside SSLV's small-satellite role, which is capped at 500 kg to LEO by ISRO.
- (D) SSLV is designed for Low Earth Orbit and small-satellite launches, not for interplanetary probe missions.
Concept
This tests the Science and Technology syllabus area on Indian space launch vehicles and their payload-orbit roles. RAS repeats such questions because ISRO missions are current-affairs-linked but require clear factual distinctions between launch vehicles.
