After a rather muted 2021 in terms of satellite launches, Indian Space Research Organisation (ISRO) is gearing up for a number of missions in 2022 including the launch of the first unmanned mission of Gaganyaan.
ISRO had a number of missions to execute this year.
- These include the launch of the Earth Observation Satellites, EOS-4 and EOS-6 on board the Polar Satellite Launch Vehicle (PSLV), and the EOS-02 on board the maiden flight of the Small Satellite Launch Vehicle (SSLV).
- ISRO has many test flights for Crew Escape System of Gaganyaan and launch of the first unmanned mission of Gaganyaan.
- Chandrayaan-03, Aditya Ll, XpoSat, IRNSS and technology demonstration missions with indigenously developed advanced technologies.
- The hardware in loop test of Aditya L1 spacecraft and accommodation studies for XpoSat in the SSLV have been completed.
- ISRO has delivered the S-band SAR payload to NASA for NISAR [NASA-ISRO SAR] mission.
- The NISAR mission, scheduled for launch in 2023, is optimised for studying hazards and global environmental change and can help manage natural resources better and provide information to scientists to better understand the effects and pace of climate change.
- Three new space science missions are also in the pipeline.
- These include a Venus mission, DISHA –a twin aeronomy satellite mission and TRISHNA, an ISRO-CNES [Centre national d’études spatiales] mission in 2024.
Back to Basics
Small Satellite Launch Vehicle (SSLV)
- The SSLV will provide a payload capability of 500 kilograms to a 500-kilometre planar orbit. By comparison, the PSLV — the workhorse of Isro — can take up to a 1,750-kilogram payload into SSO of 600 km altitude.
- The development of SSLV has been primarily envisaged to build a cost-effective launch vehicle with high launch frequency and quick turnaround capability in order to cater to the growing opportunity in the global launch services market for small satellites.
- SSLV is a three-stage all solid vehicle, which will have the option of multiple satellite mounting options for nano, micro and small satellites.
