PSLV has four stages using solid and liquid propulsion alternately.
- True
- False
Answer: True
PSLV has four stages: 1st and 3rd use solid propellant; 2nd and 4th use liquid propellant. Strap-on solid boosters enhance lift-off thrust. This alternating design optimizes performance for polar and sun-synchronous orbits. PSLV's reliability and versatility made it ISRO's workhorse for earth observation and small satellite launches.
