11-Feb-2023: ISRO successfully launches SSLV D2

SSLV-D2

  • Launched from Satish Dhawan Space Centre, Sriharikota, Andhra Pradesh.
  • This is the second attempt after SSLV-D1 failed to place satellites in precise orbit.
  • Changes were made to equipment bay, separation mechanism for stage 2, and on-board system

SSLV-D2 placed ISRO’s EOS-07 and two co-passenger satellites into orbit

  • EOS-07 is a 156.3 kg satellite designed and developed by ISRO.
  • Janus-1 is a technology demonstrator satellite built by US-based Antaris and its Indian partners XDLinks and Ananth Technologies.
    • 6-unit cube satellite with 5 payloads onboard.
    • Payloads from Singapore, Kenya, Australia, and Indonesia.
  • AzaadiSat2 is a CubeSat weighing around 8 kg and carries 75 different payloads
    • Payloads built by girl students from rural regions across the country with guidance from “Space Kidz India”.

SSLV

  • SSLV is a 3-stage launch vehicle configured with three solid propulsion stages and liquid propulsion-based Velocity Trimming Module (VTM) as a terminal.
  • SSLV is 2 m in diameter and 34m in length with a lift-off weight of 120 tonnes.
  • It is capable of launching a 10 to 500 kg satellite in 500 km planar orbit.
  • Developed to capture the emerging small (nano-micro-mini) satellite commercial market.
  • Provides low-cost access to space, low turn-around time, flexibility in accommodating multiple satellites, and demands minimal launch infrastructure.

16-Dec-2021: Government has sanctioned Rs.169 Crores for the development of SSLV project

Union Minister of State (Independent Charge) Science & Technology; Minister of State (Independent Charge) Earth Sciences; MoS PMO, Personnel, Public Grievances, Pensions, Atomic Energy and Space, Dr Jitendra Singh said, ISRO is developing a Small Satellite Launch Vehicle (SSLV) with private participation to be launched in 1st quarter of 2022.

In a written reply to a question in the Rajya Sabha today, Dr. Jitendra Singh informed that the SSLV will provide a payload capability of 500 kg to a 500 km planar orbit.

The Minister said that the development of SSLV is in the final stages and the first developmental flight of SSLV is targeted during the first quarter of 2022. He said, the Government has sanctioned a total cost of Rs.169 Crores for the development project including the development & qualification of the vehicle systems and the flight demonstration through three development flights (SSLV-D1, SSLV-D2 & SSLV-D3).

Dr. Jitendra Singh said that the hardware & structures for the SSLV development project including the solid motor cases, nozzle sub-systems, mandrels for the casting of solid motors, inter-stage structures, actuator motors & fixtures will be realized through private industry.

The development of SSLV has been primarily envisaged to realize a cost-effective launch vehicle with high launch frequency and quick turnaround capability in order to cater to the growing opportunity in the global launch services market for small satellites.
