Question

What is meant by satellite launch vehicle? Name any one Indian satellite launch vehicle.

Hint:

The Polar Satellite Launch Vehicle (PSLV) is India’s most successful satellite launch vehicle, used to place satellites into polar orbits. Another example is the Geosynchronous Satellite Launch Vehicle (GSLV), which is used for heavier payloads.

Answer 1

Step 1: Understanding satellite launch vehicles
A satellite launch vehicle is a special type of rocket used to place artificial satellites into their designated orbits around the Earth. These vehicles provide the thrust required to overcome Earth’s gravity.
Step 2: Working of a satellite launch vehicle
- The launch vehicle consists of multiple stages that ignite sequentially to propel the satellite into orbit. - It operates using liquid or solid propellants for thrust. - Once the satellite reaches its orbit, the rocket detaches, allowing the satellite to function independently.
Step 3: Example of an Indian satellite launch vehicle
One of India’s most successful satellite launch vehicles is the Polar Satellite Launch Vehicle (PSLV). It was developed by the Indian Space Research Organisation (ISRO) and is known for its reliability and capability to launch multiple satellites in a single mission. Thus, a satellite launch vehicle helps deploy satellites into space, and PSLV is a widely used launch vehicle in India.
