PSLV-C44: Microsat-R and Kalamsat-V2
  • PSLV-C44 successfully launched Microsat-R and Kalamsat-V2 on January 24, 2019, from Sriharikota.
  • Significance of the Mission
  • Microsat-R:
    • Microsat-R is a military imaging satellite, weighing 130 kilograms, was made by Defence Research and Development Organization(DRDO).
    • This was launched in low orbit. It is the first time an Indian satellite was being placed by ISRO in a low orbit at an altitude of 274 km. 
  • Kalamsat:
    • ISRO also launched a student satellite, Kalamsat, made by Space Kidz India, weighing just 1.26kg.
    • Kalamsat is the world’s smallest and lightest communication satellite.
    • Space Kidz India is an organization dedicated to designing innovative concepts for students in the field of education.
  • Fourth Stage (PS4) Usability:
    • ISRO also used this launch as an opportunity to demonstrate the usability of the fourth stage of the rocket after the satellites are ejected into orbit. 
    • The fourth and final stage of the rocket normally turns into debris after ejecting a satellite.
    • Now any agency that wants to conduct experiments in space can use the fourth stage until it disintegrates naturally. The fourth stage of the rocket will be orbiting in space for six months to a year. ISRO is aiming to use this time-frame to enable agencies to run short-time experiments.
    • Kalamsat will be the first to use the fourth stage as an orbital platform.
    • The experiment with Kalamsat will start about 1.5 hours from take-off and will last for about 14 hours. Later duration of experiments with PS4 will be improved gradually.
GSAT-31:
  • On February 06, Indian Space and Research Organisation (ISRO) has launched GSAT-31 onboard Ariane 5 rocket from French Guiana in South America.
  • GSAT-31 is India’s 40th communication satellite
  • About GSAT-31:
    • Weight: 2,536 kg
    • Payload: Ku-Band Transponders
    • Coverage Area: India Mainland and Island
    • Mission Life: 15 Years
    • Orbit: Geostationary Orbit
  • Significance:
    • The GSAT 31 will replace the satellites INSAT-4CR and INSAT-4A which are going to expire soon and will help in maintaining continuity of services currently provided by these satellites.
    • The satellite will provide connectivity to very small aperture terminals (VSAT) for ATM, stock exchange, e-governance applications, and Direct-to-Home (DTH) services.
    • It will also provide telecommunication applications for bulk data transfer for a host of applications, emergency communications, disaster management support.
