In News: ISRO will undertake the maiden flight of its newly developed Small Satellite Launch Vehicle (SSLV) on August 7.

  • On its first flight, the SSLV will carry one of India’s Earth Observation Satellites – EOS-2 – that will have applications in mapping and developing various GIS applications.
  • It will also carry the AzadiSat, a satellite developed by 750 rural students from across the country coordinated by SpaceKidz India.
  • SpaceKidz India is a space start-up creating “Young scientists” for the “Country” and spreading awareness among children for a “borderless world”.

Small Satellite Launch Vehicle (SSLV)

  • SSLV is a rocket that is designed to orbit satellites weighing less than 500kg in Low Earth Orbit and 300 kg to Sun Synchronous Orbit (SSO).
  • It is a 3 stage Launch Vehicle configured with three Solid Propulsion Stages and liquid propulsion-based Velocity Trimming Module (VTM) as a terminal stage.

Key Features

  • SSLV is the smallest vehicle at 110-ton mass at ISRO.
  • It will take only 72 hours to integrate, unlike the 70 days taken now for a launch vehicle. Only six people will be required to do the job, instead of 60 people.
  • The other features include: flexibility in accommodating multiple satellites, Launch on demand feasibility, minimal launch infrastructure requirements, etc.

Significance

Seamless launch of small satellites

  • The SSLV is intended to cater to a market for the launch of small satellites into low earth orbits with a quick turn-around time.
  • Suited for launching multiple microsatellites & supports multiple orbital drop-offs.
  • Shift the burden of commercial launches from PSLV
  • The SSLV is likely to cost a fourth of the current PSLV.
