List of SSLV launches[edit]
| Flight No. | Date and time (UTC) | Rocket, configuration | Launch site | Payload | Payload mass | Orbit | User | Launch outcome |
|---|---|---|---|---|---|---|---|---|
| D1 | 7 August 2022 03:48 | SSLV | First |  EOS 02 AzaadiSAT[1] | 143 kg | LEO (intended) TAO (achieved) | ISRO | Failure |
| The first developmental flight of SSLV. The mission target was a circular orbit of altitude 356.2 km with 37.2° inclination. The mission carried two satellite payloads. The 135 kg EOS 02, an Earth observation satellite and the 8 kg AzaadiSAT CubeSat.[2][3][4] Due to sensor failure coupled with shortcomings of onboard software, the stage as well as the two satellite payloads were injected into an unstable transatmospheric Earth orbit measuring 356×76 km and subsequently destroyed upon reentry. According to S. Somanath, an anomaly lasting 2 seconds in one of the accelerometers during second stage separation initiated salvage mode by onboard computer. Guidance, navigation, and control software switched from 'closed loop guidance' where it received real-time feedback from all sensors to an 'open loop guidance' where accelerometer data gets isolated and a predetermined path is followed.[5] This resulted in velocity shortfall from the required 7.3 km/s to 7.2 km/s. Being in salvage mode, Velocity-Trimming Module didn't rectify this shortfall which led to mission failure. | ||||||||

EOS-02: EOS-02 is configured around MicroSat-TD bus platform to demonstrate launch on demand capability with SSLV. It is expected to meet the ever-increasing user demands for cartographic applications, urban and rural management, coastal land use and regulation, utilities mapping, development and various other GIS application. The mission life of the satellite is 9 months.
