ISRO to launch Kalamsat, Microsat-R satellites on PSLV-C44 rocket

The Indian Space Research Organisation (ISRO) will Launch 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 of the ISRO in 2019.

The national space agency’s Rocket, PSLV C44 will be carrying the satellites into the orbit.

After about 14 minutes into the flight, the rocket will eject 700-kg Microsat R satellite at an altitude of about 277 km.

                                              Kalamsat Satellite
  • The Kalamsat is a 10 cm cube nanosatellite weighing about 1.2 kg and has a life span of about two months.
  • Kalamsat, prepared by a student and Chennai-based Space Kidz India, is a small satellite (10 x 10 x 10 cm) and is meant for HAM radio services.
  • It has been developed by Space Kidz India and their team including Rifath Sharook, Srimathy Kesan, among others.
  • The Kalamsat will be the first to use fourth stage (PS4) of the launch vehicle PSLV-C44 as an orbital platform. The fourth stage would be moved to higher circular orbit so as to establish an orbital platform for carrying out experiments.

Configuration of PSLV-C44 rocket

• The PSLV is a four-stage Engine Expendable Rocket with alternating solid and liquid fuel.

• One of the specialties of the launch would be the configuration of the rocket. ISRO will be using the aluminium tank for the first time in the fourth stage of the launch of PSLV C 44.

• In its normal configuration, the rocket would have six strap-on motors hugging the its first stage. However, for the launch of Kalamsat and Microsat-R satellites, the rocket will carry only two strap-on motors by the sides of the first fuel stage at the bottom.

• This is the first time the launch vehicle is built in this configuration known as PSLV-DL.

• This will reduce the weight and increase the mass in the four-stage engine expendable rocket with alternating solid and liquid fuel.

• After parking the satellites in the intended orbits, the fourth stage of the rocket will be taken to a circular orbit in space for carrying out certain experiments by the scientists.

• 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.
