In order to maintain contact with Gaganyaan mission, the Indian Space Research Organization (ISRO) is going to launch data relay satellites.
About the mission
- The satellite will be launched before the final leg of the Gaganyaan mission, which will send astronauts to the Lower Earth Orbit (LEO).
- The first leg -- the unmanned mission -- is to be launched in December.
- Project costing: 800 crores
The need of relay data
- Satellites in orbit cannot pass along their information to the ground stations on Earth if the satellite does not have a clear view of the ground station.
- A data relay satellite serves as a way to pass along the satellite’s information.
NASA’s Relay Satellite
- The NASA, with a robust human space mission programme, also has its own data relay satellite.
- It’s Tracking and Data Relay Satellite allows it to have global coverage of all the satellites round the clock without having to build extra ground stations on Earth.
- The ISRO uses several ground stations spread across the globe -- Mauritius, Brunei and Biak, Indonesia.
