Context:

The Indian Space Research Organization will send a small satellite launch vehicle. It is a three-stage vehicle with all solid propulsion stages.

Details

• The mission is to launch Earth Observation Satellite, EOS-02, and a co-passenger satellite, 'Azaadi SAT', into low earth orbit.
• The 'Azaadi Satellite' is designed by 750 girl students of government schools in rural areas from Kashmir to Kanyakumari.
• AzadiSAT is the result of ISRO pushing for girls to take up Science, Technology, Engineering, and Mathematics (STEM).
• The eight-kilogram CubeSat carries 75 different payloads, each weighing around 50 grams, that will conduct femto-experiments.
• ISRO will use the ground system that is developed by Space Kidz India for telemetry and communicating with the payloads in orbit.

SSLV

About: The Small Satellite Launch Vehicle (or SSLV) is a small-lift launch vehicle being developed by the Indian Space Research Organisation (ISRO).

Aim: The SSLV was developed with the aim of launching small satellites commercially at drastically reduced price and higher launch rate as compared to Polar Satellite Launch Vehicle (PSLV).

Capacity and Features:

It has a payload capacity to deliver 600 kg. SSLV is a three-stage, all-solid launch vehicle that can carry a payload weighing 500 kilograms to the polar orbit, 500 kilometers above Earth's surface and a 300-kilogram payload into Sun Synchronous Polar Orbit.

It has the capability to support multiple orbital drop-offs.

The SSLV is the smallest vehicle at 110-ton mass at ISRO.

It can carry satellites weighing up to 500 kg to a low earth orbit while the tried and tested PSLV can launch satellites weighing in the range of 1000 kg.
