Small Satellite Launch Vehicle (SSLV-D2)

Subject : Science and technology

Section : Space Technology

Concept :

  • 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.

About the Small Satellite Launch Vehicle:

  • The new vehicle was developed to capture the emerging small and microsatellite commercial market.
  • The SSLV (2m in diameter and 34m in length ) 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.
  • The key features of SSLV are –
    • Low cost,
    • With low turn-around time,
    • Flexibility in accommodating multiple satellites,
    • Minimal launch infrastructure requirements (assembled by a small team in a week, compared to 6 months and 600 people for ISRO’s workhorse PSLV), etc.
    • It placed the Indian Space Research Organisation (ISRO) earth observation satellite EOS-07 and two co-passenger satellites — Janus-1 and AzaadiSat2.
  • Note :
    • The SSLV’s first development flight (August 2022, EOS 02), failed to place the satellites in precise orbit.
    • A new vehicle is declared operational by the space agency after it completes two successful development flights.

  • EOS-07
    • The EOS­07 is a 156.3­kg satellite designed, developed and realised by the ISRO.
    • Its mission objective is to design and develop payload instruments compatible with micro satellite bus and technologies that are required for future operational satellites.
    • It would design and develop a microsatellite accommodating new technology payloads in a quick turnaround time. New experiments include mm­ Wave humidity sounder and spectrum monitoring payload.
  • Janus-1
    • Janus-1 is a technology demonstrator satellite built by United States-based Antaris and its Indian partners XD Links and Ananth Technologies.
    • It weighs only 10.2 kg and is a six-unit cube satellite with five payloads on board — two from Singapore, and one each from Kenya, Australia, and Indonesia.
  • AzaadiSat2
    • The payloads have been built by 750 girl students from across India.
    • The payloads include: LoRa amateur radio, a sensor to measure radiation levels in space, and sensors to measure the health of the satellite such as temperature, reset count, and inertial data.
