New Delhi: ISRO will launch the second developmental flight of SSLV from Sriharikota on Friday. According to the ISRO’s announcement on Wednesday the SSLV-D2 will soar into the skies at 9:18 am from the first launch pad at the SDSC SHAR and attempt to put three satellites into a 450 km circular orbit during its 15 minute flight.

The three satellites are ISRO’s EOS-07, US-based firm Antaris’ Janus-1 and Chennai-based space start up SpaceKidz’s AzaadiSAT-2. The first test flight of SSLV had ended in partial failure on August 9th 2022, as the rocket failed to inject its satellite payload in their intended orbits. SSLV caters to the launch of up to 500 kg satellites to low earth orbits on ‘launch-on-demand’ basis. It provides low-cost access to space, offers low turn-around 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 having a lift-off mass of 120 tonnes.

EOS-07 is a 156.3 kg satellite which has been designed, developed and realized by ISRO. New experiments include mm-Wave Humidity Sounder and Spectrum Monitoring Payload. While, Janus-1, a 10.2 kg satellite, belongs to Antaris, USA. A 8.7 kg satellite, AzaadiSAT-2, is a combined effort of about 750 girl students across India guided by Space Kidz India, Chennai.
