PSLV-C54

Syllabus: General Studies Paper 3

In one of its longest missions, the Indian Space Research Organisation (ISRO) successfully placed nine satellites, including an Earth Observation Satellite (EOS-06) in multiple orbits with the help of the space agency’s Polar Satellite Launch Vehicle (PSLV-C54).

  • The eight nano satellites include ISRO Nano Satellite-2 for Bhutan (INS-2B), Anand, Astrocast (four satellites), and two Thybolt satellites. Notably, EOS-6 is the Oceansat series’ third-generation satellite. 
  • This is the 56th flight of the Polar Satellite Launch Vehicle (PSLV) and the 24th flight of the PSLV-XL version with 6 PSOM-Xls.

About the Satellites

  • EOS-06 is envisaged to observe ocean colour data, sea surface temperature and wind vector data to use in oceanography, climatic and meteorological applications. 
  • The satellite also supports value added products such as potential fishing zone using chlorophyll, SST and wind speed, and land based geophysical parameters.
  • It is the Oceansat series’ third-generation satellite, which provides continued services of Oceansat-2 with enhanced payload capability.
  • The satellite onboard carries four payloads.
  • Astrocast, a 3U spacecraft with 4 Satellites from Spaceflight Inc, U.S., were separated.
  • The Thybolt, a 0.5U spacecraft bus that includes a communication payload to enable rapid technology demonstration and constellation development for multiple users from Dhruva Space using their own Orbital Deployer with a minimum lifetime of one year, was deployed in the intended orbit. 
  • The Anand three axis stabilised nano satellite, a technology demonstrator for miniaturised electro-optical payload and all other sub-systems like TTC, power, onboard computer and ADCS from Pixxel, India was also placed in the orbit.
  • The INS-2B satellite has two payloads namely NanoMx, a multispectral optical imaging payload developed by Space Applications Centre (SAC) and APRS-Digipeater, which is jointly developed by DITT-Bhutan and URSC.

Future launches

  • Aditya-L1, a coronagraphy spacecraft to study the solar atmosphere, with a PSLV rocket.

About Polar Satellite Launch Vehicle(PSLV):

  • PSLV is known as the ‘workhorse’ of ISRO.
  • It is the third generation launch vehicle of India.
  • It is a four-staged launch vehicle with first and third stages using solid rocket motors and second and fourth stages using liquid rocket engines.
  • It is the first Indian launch vehicle to be equipped with liquid stages.

Question: India’s space programme is playing pivotal role to strengthen India’s ties with other countries. Discuss.
