After the Indian Space Research Organisation’s (Isro) newly developed small satellite launch vehicle (SSLV) suffered some data losses in the final stage of its maiden flight Sunday morning, the space agency said it is analysing the status of satellites and the SSLV performance.
Isro chairperson Dr S Somanath said: “We had in the terminal phase of the mission some data losses occurring and we are analysing the data. And, we will come back on the status of the satellites as well as the vehicle performance soon.”
The new rocket was carrying earth observation satellite EOS-02 weighing 145 kg and AzaadiSat, made by 750 school girls to celebrate the 75 years of Independence under SpaceKidz India, weighing 8 kg.
The SSLV, which uses three solid fuel-based stages and a liquid fuel-based velocity trimming module (VTM) to place the satellite in orbit, was designed keeping in mind the quick turnaround time needed for commercial launch. The launch using the vehicle can be carried out within a week, with Somanath telling The Indian Express that the vehicle can be integrated in two days, tested for the next two, with rehearsal and launch in another two days. This was achieved during the current mission, he said Saturday.
The lift-off from India’s only spaceport in Sriharikota at 9:18 am was typical of any other launch and remained so for the first three stages of the vehicle. But there was some deviation from the mapped trajectory during the coasting phase, with the third stage separation, VTM ignition, and satellite injection a little delayed from what was mentioned in the space agency’s mission brochure.
There was a silence in the mission control room after the separation of the satellites on board at 738 and 788 seconds after the lift-off.
“The maiden flight of SSLV D1 just now completed. All stages performed as expected. We are currently in the process of analysing the data to conclude the outcome of the mission concerning whether a stable orbit is achieved or not,” Somanath said.
All stages of SSLV performed as expected, but suffered data loss at terminal phase of the mission, says ISRO Chief S. Somanath. “We are analysing the data and will come back on the the status of the satellites as well as the vehicle performance soon”, he said.
ISRO’s maiden small satellite launch vehicle (SSLV), carrying earth observation satellite EOS-02 and co-passenger students satellite AzaadiSAT lifted off from the Satish Dawan Space Centre on Sunday. The SSLV-D1/EOS-02 mission by the Indian space agency is aimed at garnering a larger pie in the small launch vehicles market, as it can place the satellites into Low Earth Orbit.
ISRO has launched a mission to place satellites weighing up to 500 kg into 500 km low earth orbit in order to gain a larger share of the competitive SSLV market. “SSLV-D1/EOS-02 Mission: the countdown commenced at 02.26hrs," ISRO said on its website on Sunday. The launch was scheduled at 9:18 AM.
