The Indian Space Research Organization will begin the second developmental flight of Small Satellite Launch Vehicle (SSLV) on Friday from its first launch pad Satish Dhawan Space Center at Sriharikota in Andhra Pradesh. It will be launched at 9:18 am.
The Indian Space Research Organization (ISRO) said that SSLV-D2 will attempt to place three satellites in a orbit of 450 km during its 15-minute flight.
Here are things to know:
1) The three satellites that SSLV-D2 will attempt to launch are ISRO's EOS-07, US-based firm Antaris's Janus-1 and Chennai-based space startup SpaceKidz's Azadisat-2.
2) ISRO said, SSLV caters to the launch of satellites up to 500 kg into low earth orbits on a 'launch-on-demand' basis. It provides low-cost access to space, short turn-around times and the flexibility to accommodate multiple satellites, and demands minimal launch infrastructure.
3) It is configured with three solid propulsion stages and a velocity terminal module. It is a 34 m long, 2 m diameter vehicle with a lift off mass of 120 tonnes.
4) EOS-07 is a 156.3 kg satellite designed, developed and manufactured by ISRO. New experiments include the mm-wave humidity sounder and spectrum monitoring payloads. Whereas, Janus-1, a 10.2 kg satellite, belongs to Antaris of the US. The 8.7 kg satellite, Azadisat-2, is a joint effort of about 750 girl students from across India, guided by Space Kids India, Chennai.
5) The first test flight of SSLV last August 9 was a partial failure as the rocket failed to inject its satellite payloads into their intended orbits. An investigation into the failure of SSLV-D1 by ISRO revealed that the mission failed after the upper stage of the launch vehicle injected the satellite into a highly elliptical unstable orbit due to a reduction in velocity.
