PSLV-C35 to inject eight satellites in different orbits [S&T]

  • In its first multi-orbital launch, India’s workhorse PSLV will inject eight different satellites, including the country’s weather satellite SCATSAT-1 and five from other nations, into two different orbits.
  • The mission objectives of SCATSAT-1 are to help provide weather forecasting services to the user communities through the generation of wind vector products for weather forecasting, cyclone detection and tracking.
  • SCATSAT-1 is a continuity mission for scatterometer payload carried by the earlier Oceansat-2 satellite.
  • Things to know about the PSLV’s longest-ever flight:
    • There will be two re-ignitions of the launch vehicle for this purpose.
    • Besides SCATSAT-1, the others are PRATHAM and PISAT, two academic satellites from India; ALSAT-1B, ALSAT-2B and ALSAT-1N (all from Algeria); and Pathfinder-1 and NLS-19, from the USA and Canada, respectively.
    • This will be the 15th flight of PSLV in ‘XL’ configuration with the use of solid strap-on motors.
    • The five-kg student satellite PISAT carries an imaging camera as payload to capture imagery of 185 km x 135 km area with about 80m/pixel resolution. The satellite is developed by students of PES University, Bengaluru.
    • The other student satellite, PRATHAM, is developed by IIT Bombay.
    • The PSLV has so far launched 39 remote-sensing satellites of ISRO, including the Chandrayaan-1 of 2008 and the Mars mission of 2013-14.
    • It has also orbited 74 foreign commercial and university satellites in a global trend where the demand for its category of launch services is increasing.
