SSLV-D2 Vehicle Configuration: The SSLV-D2, or Small Satellite Launch Vehicle, is a three-stage rocket. It is crucial to note that the first three stages are powered by solid propellants, while the final stage, the Velocity Trimming Module (VTM), uses liquid propulsion. Statement 1 incorrectly states that the vehicle is powered *entirely* by liquid propulsion, which is a key detail to identify as false.
Payloads of SSLV-D2: The SSLV-D2 successfully launched three satellites:
EOS-07 (Earth Observation Satellite-07): A 150 kg satellite developed by ISRO, designed for Earth observation applications.
Janus-1: A 10 kg technology demonstrator satellite from SpaceKidz India.
AzaadiSAT-2: Another 8 kg nanosatellite from SpaceKidz India, built by students, which serves as a follow-on to AzaadiSAT.
Orbital Insertion: The mission aimed to place these satellites into a circular low Earth orbit. The target orbit was specified as approximately 450 km circular. Statement 1's mention of a 450 km circular orbit is correct, but its other inaccuracies make the entire statement false.
Key Strengths Highlighted: The SSLV-D2 mission underscored the vehicle's rapid deployment capabilities. This implies that it can be assembled, integrated, and launched relatively quickly compared to larger launch vehicles.
Turnaround Time and Infrastructure: A significant advantage of the SSLV is its requirement for minimal ground infrastructure and a short turnaround time between launches. This makes it a cost-effective solution for launching small satellites. Statement 2 accurately captures these operational advantages.
Target Audience Focus: For exams, remember that SSLV is designed for on-demand launch of small satellites, catering to a growing market for small satellite constellations. Its lower cost and flexibility are its defining features.
