Modified PSLV places three foreign satellites in orbit

In a scorching summer evening that was accompanied by blue skies that were clear, the Indian Space research Organization’s (ISRO) mainstay launch vehicle for its 55th mission, PSLV-C53, soared in the night sky illuminating the sky with a pencil-shaped puff of smoke. It then curved away, and then injected three Singaporean satellites into their planned orbits on the second mission by the commercial division of ISRO, New Space India Limited (NSIL).

The mission also served as an other purpose for ISRO who chose to utilize its fourth platform, known as the PS4 to serve as a stationary platform orbiting the earth to conduct experiments in science. ISRO chairman, S. Somanath, described the maneuver to be “a poem in orbit”.

He said. Somanath said that, typically the fourth stage would be buried in space. However, ISRO has reused the fourth stage, and had introduced an electronic control system that can activate its thrusters and sensors like stars that let it to observe the stars, pinpoint its own location as well as communicate commands from the ground. The fourth stage could be utilized for missions where the weight is not heavy, as in the PSLV-C53. When missions have larger payloads, like an coming launch that will feature the 1.5 ton satellite, there’ll be not enough propulsion to run the POEM.

S.R. Biju the Mission Director stated that the PSLV was operating in an entirely different configuration this time around, with the standalone version of the PSLV having been used for a long period of. “We had to introduce some changes to improve the production of PSLV so that we can meet the growing demand of customers, which we have implemented, and it has yielded results,” Biju said.

The Fourth stage, and the POEM Ms. Biju said ISRO would be able to take over the PS-4 stage and provide the stage some motivation to conduct certain cost-effective orbital experiments which can meet the increasing demands of startups as well as the scientific and student communities. “Left to its own devices it would have followed its own path, stumbled and wobbled, or could have swung. However, if it had more energy, we’ll be able to keep running the active PS-4 for a longer period of time and ensure that the platform will be available and all resources are readily available, and you can keep some payloads from science there to be used for a second purpose,” he said.

The modified PSLV C53 launched at the launchpad 2 located at the Satish Dhawan Space Centre, Sriharikota Range (SHAR), at 6.02 p.m. and landed three satellites — one 365-kg earth satellite, Singaporean Observation Satellite, also known as DS-EO which is a 155 kg commercial satellite that has an Synthetic Aperture Radar (SAR) payload as well as the NeuSAR satellite; and an 2.8 kilogram satellite of Nanyang Technological University (NTU) and SCOOB-1 — both of which entered orbit within 19 minutes of launch.

It was one of the few times since the beginning of December that a launch was permitted to be watched by the public and media. permitted to visit access the Visitors Gallery, marking a peace of mind at the spaceport since the COVID-19 epidemic struck the globe and restrictions on lockdowns were put in place.

“After the initial mission PSLV-4th stage going to create some poems on orbit. Its PSLV Orbital Experimental Module (POEM) will be operational following the placing of satellites into orbit] and taking the command of the primary mission computer to a second computer. Fourth stage is powered, producing energy on board and stabilized with the ability to control altitude and host experiments conducted by a few of the new startups that are supported through InSpace,” Mr. Somanath stated in a statement from Mission Control.
