Answer:

The correct answer is option 'B', i.e., statement 2 only.

Explanation:

The Small Satellite Launch Vehicle (SSLV) is a launch vehicle developed by the Indian Space Research Organisation (ISRO) to cater to the increasing demand for launching small satellites. It is designed to provide a cost-effective and reliable solution for launching small satellites to low Earth orbits.

Statement 1: It launches up to 2500 kg satellites to low Earth orbits.

This statement is incorrect. The SSLV is designed to launch small satellites weighing up to 500 kg to low Earth orbits. It is not capable of launching satellites weighing up to 2500 kg. The SSLV is specifically designed for small satellite missions and is intended to provide dedicated launch services for small satellites.

Statement 2: The launch vehicle uses three solid stages followed by a liquid-fuel-based Velocity Trimming Module (VTM) to place satellites in orbit.

This statement is correct. The SSLV consists of three solid stages and a liquid-fuel-based Velocity Trimming Module (VTM). The first stage of the SSLV is powered by a solid rocket motor, while the second and third stages also use solid propellants. The VTM is a liquid-fueled stage that is used to fine-tune the velocity and trajectory of the launch vehicle to precisely place the satellites in their intended orbits.

The VTM is powered by a liquid-fuelled engine that provides more control and flexibility in terms of trajectory and orbital insertion. This allows the SSLV to accurately deliver small satellites to their desired orbits, even in complex mission scenarios.

In conclusion, statement 2 is correct as it accurately describes the launch vehicle configuration of the Small Satellite Launch Vehicle (SSLV). However, statement 1 is incorrect as the SSLV is designed to launch small satellites weighing up to 500 kg, not 2500 kg.

The Indian Space Research Organisation (ISRO) successfully launched the second edition of the Small Satellite Launch Vehicle (SSLV-D2) from the first launch pad of Satish Dhawan space centre at Sriharikota, Andhra Pradesh.
  • The new vehicle was developed to capture the emerging small and microsatellite commercial market.
  • The SSLV caters to the launch of up to 500 kg satellites to low earth orbits on a 'launch-on-demand' basis.
  • The launch vehicle uses three solid stages followed by a liquid-fuel-based Velocity Trimming Module (VTM) to place satellites in orbit.
Hence only statement 2 is correct.
