Microsat-R was an Indian satellite . It was launched in January 2019 by the Indian space agency on behalf of the Indian military . On March 27, 2019, it served as a target for an anti-satellite missile test and was successfully destroyed.

Development and start

Microsat-R was developed by the Defense Research and Development Organization (DRDO), a research network under the control of the Indian Ministry of Defense. The satellite weighed 740 kg and was declared an earth observation satellite .

On January 24, 2019 at 11:37 p.m. local time, a PSLV rocket lifted off the first launch pad of the Satish Dhawan Space Center . It brought Microsat-R into space together with the student-built Kalamsat-V2 nanosatellite . After 13 minutes, the main payload was placed in orbit at an altitude of 272 km, the PSLV's lowest target orbit to date. Kalamsat-V2 remained on the fourth stage, which detonated twice more to reach a 450 km high orbit. They should burn up in the earth's atmosphere within about half a year. In fact, after five months there were still about 120 bridges at least 10 centimeters in size in orbits of up to one kilometer in height.

It was the 46th PSLV launch and the first flight of the new PSLV-DL rocket version. For the first time, the fourth stage also serves as a platform for further experiments.

Launch

The Indian military used a PDV Mk II missile ( Prithvi Defense Vehicle Mark II ; for example: Earth Defense Equipment Version 2), which is based on the Agni-V ICBM . It weighs about 18 tons and consists of three stages , the first two of which use a solid fuel drive.

The interceptor rocket was launched on March 27, 2019 at around 11:10 a.m. local time from the Integrated Test Range missile test site on Abdul Kalam Island . After about three minutes, its third stage hit the satellite at an altitude of almost 300 km and at a relative speed of around 10 km / s. According to the DRDO, this operation, code-named "Mission Shakti", had been in preparation for two years. The satellite was hit in the middle and with a few centimeters of target deviation. On the same day, the US Air Force registered around 270 pieces of debris.

India became the fourth country after the USA , the Soviet Union and China to demonstrate the launch of a satellite with a rocket.

Reactions

Path development of the debris collected by April 20, 2019

Indian Prime Minister Narendra Modi announced the success of the test in a televised address and said India was now a global space power. The newly developed ability is not directed against anyone, and India rejects an arms race in space. The Indian Congress President Rahul Gandhi accused him of "political theater". In general, the action was seen domestically in the context of an imminent parliamentary election.

The Times of India headlined “India shoots into the star wars club” and viewed the satellite launch as a show of force directed at both Pakistan and China. A spokesman for the Pakistani Foreign Ministry said India's behavior was reminiscent of Don Quixote's fight against windmills.

Various experts estimate the risk of additional space debris to be relatively low due to the satellite's low orbit. Most of the debris will enter the earth's atmosphere within a few weeks. Individual parts have also been promoted to higher levels. NASA Administrator Jim Bridenstine expressed general concern about space debris from satellite launches and accused other, unspecified countries of relying on the United States for free monitoring of self-created debris fields by services. The US State Department avoided any criticism of India.
