What’s in News:
- The Indian Space Research Organisation (ISRO) successfully launched three Singaporean satellites in a commercial mission of the New Space India Limited.
- In addition to the international payloads, the rocket also carried six experiments in its fourth stage, including two from Indian startups Digantara and Dhruva Space.
- The PSLV Orbital Experiment Module (POEM) uses the spent fourth stage of the rocket as an in-orbit platform by adding solar panels, a battery, and a navigation control system.
- Usually, after putting the satellite in orbit, the rocket stages decay, return to the atmosphere and burn up. But, with the addition of a little power to keep the stage in orbit, they can be utilised for experiments.
- Polar Satellite Launch Vehicle (PSLV) is the third generation launch vehicle of India. It is the first Indian launch vehicle to be equipped with liquid stages.
- It is a four-staged launch vehicle with first and third stages using solid rocket motors and second and fourth stages using liquid rocket engines.
- PSLV has also been used to launch various satellites into Geosynchronous and Geostationary orbits
