SRO Chairman S Somanath informed on Sunday that the space agency’s first Small Satellite Launch Vehicle (SSLV) suffered “data loss” at the terminal stage, although three stages “have been completed and separated “, and said the space agency was analyzing the data to determine the status. vehicle and satellites.

SSLV-D1/EOS 02 carried an earth observation satellite and a student satellite.

“All the steps went as planned. The first stage performed and separated, the second stage performed and separated, the third stage also performed and separated, and in the terminal phase of the mission, data loss occurs and we analyze the data and we will come back to the status of satellites as well as vehicle performance soon,” Somanath said from Mission Control here, minutes after the launch vehicle lifted off from the spaceport.

A jubilant mood in the mission control center quickly gave way to anxiety, before Somanath was briefed on the status of the mission.

ISRO’s first Small Satellite Launch Vehicle (SSLV), carrying the EOS-02 Earth observation satellite and the AzaadiSAT co-passenger student satellite, lifted off from this spaceport on Sunday. The Indian space agency’s SSLV-D1/EOS-02 mission aims to get a bigger share of the small launcher market because it can place the satellites into low Earth orbit.

The SSLV can place payloads (mini, micro or nanosatellites) weighing up to 500 kg into the 500 km planar orbit, the Indian Space Research Organization (ISRO) said.

After a seven-and-a-half-hour countdown, the 34-meter-long SSLV lifted off majestically at 9:18 a.m. under cloudy skies to place the satellites in the planned orbit.

EOS-02 is an experimental high spatial resolution optical remote sensing satellite. The aim is to build and fly an experimental imaging satellite with a short turnaround time and demonstrate launch-on-demand capability. EOS-02 belongs to the series of microsatellite spacecraft.

The AzaadiSAT is an 8U Cubesat weighing about 8 kg. It carries 75 different payloads each weighing around 50 grams. Students in rural areas across the country received advice on building these payloads.

The payloads are integrated by the student team of ‘Space Kidz India’. The ground system developed by Space Kidz India will be used to receive data from this satellite, ISRO said.

All stages of SSLV went as planned, but suffered data loss in the terminal phase of the mission, says ISRO chief Somanath.
