On the morning of February 10, the Indian Space Research Organization (ISRO) successfully launched SSLV-D2. Which is its second developmental flight, and successfully positioned three satellites in a precise orbit.
The three satellites are the Janus-1 from American company Antaris, the EOS 07 Earth Observation Satellite from ISRO, and the AzaadiSAT-2 from Chennai-based SpaceKidz.
At 9:18 a.m., SSLV-D2 launched from the Satish Dhawan Space Centre-primary SHAR’s launch pad in Sriharikota. The first satellite launch of 2023 is this one.
The last liquid propellant-based velocity-trimming module, designed to precisely place the satellites in orbit. Reached the desired altitude but the satellite separation did not start, the scientists waited in silence for a little period of time. The first satellite, EOS-07, split at 801 seconds instead of 785 seconds after launch. Janus -1 at 903 seconds instead of 880, and Azadisat 2 at 923 seconds instead of 900. This is a few seconds later than what the mission brochure had stated. Every mission further involves a few minor variations.
Here is the official tweet from ISRO’s official handle:
Recall that the SSLV’s maiden test flight, which departed from Satish Dhawan Space Center on August 7, 2022, was a partial failure. The rocket was unable to place its satellite payload into the desired orbit.
Despite the normal operation of all solid propulsion stages, the spacecraft decayed and deorbited immediately after being injected into a very elliptical unstable orbit, according to ISRO.
About the rocket launched:
The 156.3 kilogramme EOS-07 satellite was created, constructed, and launched by ISRO. Designing and creating payload instruments that are compatible with the microsatellite bus and cutting-edge technologies. The same are therefore needed for future operational spacecraft, is the goal of EOS-07’s mission. Additionally, it will quickly design and manufacture a microsatellite capable of carrying innovative technological payloads.
According to information published by ISRO, SSLV supports the “launch-on-demand” launch of satellites weighing up to 500 kg. It offers low launch infrastructure requirements, quick turnaround times, flexibility in housing several satellites, and affordable access to space. It is set up with a velocity terminal module and three solid propulsion stages.
