ISRO launches Kalamsat, Microsat-R satellites on PSLV-C44 rocket

The Indian Space Research Organisation (ISRO) launched a students’ satellite Kalamsat and an imaging satellite Microsat-R from the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh on January 24, 2019, marking its first launch in 2019.

The national space agency’s rocket, PSLV C44 carried the satellites into the orbit. After about 14 minutes into the flight, the rocket ejected the 700-kg Microsat R satellite at an altitude of about 277 km.

KEY FEATURES:-

1. This was the first time the launch vehicle is built in this configuration known as PSLV-DL.
2. This will reduce the weight and increase the mass in the four-stage engine expendable rocket with alternating solid and liquid fuel.
3. The PSLV is a four-stage engine expendable rocket with alternating solid and liquid fuel.
4. One of the specialties of the launch was the configuration of the rocket. ISRO used the aluminum tank for the first time in the fourth stage of the launch of PSLV C 44.
5. In its normal configuration, the rocket would have six strap-on motors hugging its first stage. However, for the launch of Kalamsat and Microsat-R satellites, the rocket carried only two strap-on motors by the sides of the first fuel stage at the bottom.
6. Normally, the fourth stage is kept deserted in space after the injection of the satellites. This time, it will be kept ‘live’ for carrying out innovative studies.
