According to the "India Express" reported on August 8, the Indian small satellite carrier rocket launched on the 7th local time failed to send the carried satellite into the scheduled track. The launch task failed. However, the Indian Space Research Organization said that the first flight can be called "partial success."

On the morning of the 7th, the Indian Space Research Organization launched a small satellite launch vehicle for the first time in the Satshda Dawan Dawan Space Center, located in Srihuroga, Srihuroga, southeast India. In this launch, this new rocket is equipped with a 145 kg of earth observation satellite EOS-02 and 8 kg of Azaadisat satellites, which was manufactured by 750 female students in India to celebrate India's 75th anniversary.

According to the Indian media reports, after the launch of the Rockets and the cheers and applause at various stages, the two satellites were separated in 738 seconds and 788 seconds after launch, but the flight control room was silent. This is because the data is lost.

The Indian Space Research Organization, which is responsible for this task, stated that the first flight of the newly developed small satellite carrier rocket can be called partial success. The work of three solid fuel promotion phases is normal, but due to the logical failure of identifying the sensor, the satellite has entered a wrong error. Ellipse orbit.

In a video statement on the afternoon of the 7th, Somanat, chairman of the Indian Space Research Organization, said: "The Rockets take off solemnly after the first level of burning, and the subsequent S2 and S3 levels performed very well. The task performance is very good. In the end, when it reached the track of 356 kilometers, the satellite was separated. However, we then noticed that the satellite position was abnormal on the orbit. "

The Indian Space Research Organization said, "Due to the failure of the rocket recognition sensor, the satellite actually entered the oval track of 76X356 kilometers, rather than the round orbit of 356 kilometers in the original plan. The satellite is no longer available."

Chairman Somanat said that placing satellites on the wrong track was due to the failure of the rocket to identify the sensor failure. This problem has been "reasonably determined", but it will be more in -depth analysis.

"Every other new elements contained in this rocket are very good, including the promotion stage, overall hardware, aerodynamic design, new generation of low -cost electronic equipment, control systems, new separation systems, and the entire architecture of the Rockets Everything has been proved for the first time on the Rockets, and we are happy to this. "

Somanat said that no matter what the expert group's suggestion is, it will be executed immediately.
