ISRO is to make 2nd attempt to launch a new mini-vehicle SSLV Today at 9.18 am.

On Friday, the Indian Space Research Organization's Small Satellite Launch Vehicle (SSLV) launched three satellites, including the earth observation satellite EOS-07, into their assigned orbits in its second developmental mission.

The SSLV-D2/EOS-07 mission's success comes after India's smallest commercial rocket, which stands 34 metres tall and has a diameter of two metres, failed to inject satellites into the appropriate orbits during its first launch on August 7, last year.

SSLV-D2 lifted off from the first launch pad at Satish Dhawan Space Centre in Sriharikota at 9.18am. Around 13 minutes after lift-off, the three-stage rocket successfully placed EOS-07 in a circular orbit. Around 1.6 minute later, it placed Janus-1 and AzaadiSAT-2 satellites in their orbits.

Following the mission's accomplishment, Isro chairman S Somanath stated, "We have a new launch vehicle." The mission's goals, according to Isro, are to demonstrate the in-flight performance of SSLV vehicle systems and to inject the three satellites into a 450km circular orbit.

EOS-07, weighing 156.3kg, has a one-year mission life. The EOS-07 mission goal was to design and develop payload instruments that are compatible with a micro satellite bus and new technologies needed for future operational satellites, as well as to design and develop a micro satellite that can accommodate new technology payloads in a short amount of time.

Janus-1 is a smart satellite technology demonstration built on the Antaris software platform from the United States. AzaadiSAT-2's goals include proving LoRa and amateur radio communication capabilities, as well as detecting radiation levels in space. Around 750 female students were mentored in the development of the payloads. These payloads were integrated by the Space Kidz India student team.

SSLV is a three-stage vehicle that consists of all solid propulsion stages and a liquid propulsion-based velocity trimming module as the terminal stage. SSLV's design drivers include cheap cost, quick turnaround, flexibility in housing many satellites, launch-on-demand capability, and minimal launch infrastructure needs.
