In news: 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 mission was accomplished from Satish Dhawan Space Centre SHAR.
  • 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.
  • The nano satellites include ISRO Nano Satellite-2 for Bhutan (INS-2B), Anand, Astrocast (four satellites), and two Thybolt satellites.

About the satellites:

  • EOS-6:
  • 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.
  • It 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 parameter.

  • Astrocast, a 3U spacecraft with 4 Satellites is from Spaceflight Inc, U.S.

  • Thybolt is 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.

  • The Anand is a three-axis stabilised nano satellite and a technology demonstrator for miniaturised electro-optical payload.

  • INS-2B satellite or India-Bhutan 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.
  • Sub-systems like TTC, power, onboard computer and ADCS from Pixxel, India was also placed in the orbit.

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.
