Explained: ISRO’s SSLV, a small satellite launcher with big prospects ahead

What is the News?

ISRO Chairman has said that the Small Satellite Launch Vehicle(SSLV) named “SLV-D1 Micro SAT” will be launched in April 2022.

What is a Small Satellite Launch Vehicle(SSLV)?

It is an all-solid three-stage vehicle with the capability to launch up to 500 kg satellite mass into 500 km Low Earth Orbit(LEO).

Why was the SSLV developed?

The SSLV  has been developed to cater to a market for the launch of small satellites into low earth orbits.

The demand for small satellites has emerged in recent years on account of the need for developing countries, private corporations, and universities for small satellites.

Until now, the launch of small satellites is dependent on ‘piggy-back’ rides with big satellite launches on ISRO’s Polar Satellite Launch Vehicle, which has had over 50 successful launches so far.

What are the advantages of SSLV? 

The SSLV would help in a) Reduced Turn-around Time b) Launch on Demand c) Cost Optimization for Realization and Operation d) Flexibility in accommodating Multiple Satellites and e) Minimum launch infrastructure requirements.

What is the significance of SSLV Satellites?

The development and manufacture of the SSLV are expected to create greater synergy between the space sector and private Indian industries – a key aim of the space ministry.
