SMALL SATELLITE LAUNCH VEHICLE-D2

  • The Indian Space Research Organisation (ISRO) will undertake the second development flight of the Small Satellite Launch Vehicle (SSLV) on Friday from Sriharikota. The SSLV-D2 will lift off at 9.18 a.m. from the first launch pad at the Satish Dhawan Space Centre-SHAR, Sriharikota.
  • The vehicle is intended to inject the ISRO’s EOS-07, the U.S.-based firm Antaris’s Janus-1 and the Chennai-based space start-up Space Kidz’s AzaadiSAT-2 satellites into a 450-km circular orbit in its 15-minute flight.
  • The EOS-07 is a 156.3-kg 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 micro satellite accommodating new technology payloads in a quick turnaround time.
  • New experiments include mm-Wave humidity sounder and spectrum monitoring payload.
  • Weighing around 10.2 kg, Janus-1 is a technology demonstrator, smart satellite mission based on the Antaris software platform.
  • A 8.7-kg satellite, AzaadiSAT-2 is a combined effort of about 750 girl students across India guided by Space Kidz India, Chennai.
  • According to details provided by ISRO, SSLV caters to the launch of satellites weighing up to 500 kg to low earth orbits on a ‘launch-on-demand’ basis.
  • It provides low-cost access to space, offers low turnaround time and flexibility in accommodating multiple satellites, and demands minimal launch infrastructure.
  • It is configured with three solid propulsion stages and a velocity terminal module. It is a 34-m-tall, 2- m-diameter vehicle with a lift-off mass of 120 tonnes.
