NEW DELHI : The Indian Space Research Organisation (Isro) has finally announced the launch date of its C53 mission for the Polar Satellite Launch Vehicle (PSLV). The mission faced multiple initial delays, but was eventually slated for launch this year following the launch of the PSLV-C52 mission in February this year.

The mission will carry a payload of three satellites from Singapore, including an Earth Observation satellite. Both the EO satellite and the NeuSAR synthetic aperture radar satellites will contribute to satellite imagery tasks, for tertiary clients of Isro’s.

The mission is also the second dedicated commercial space mission for India, contracted by the newly appointed public sector undertaking organisation, New Space India Limited (NSIL). The latter is tipped to bring commercial contracts for Isro going forward, and work alongside IN-SPACe (Indian National Space Promotion and Authorisation Centre) to help private sector organisations work alongside India’s central space agency.

The PSLV-C53 mission will also carry in-orbit experiments to orbit with the mission’s fourth stage. The latter, which typically burns in orbit and disintegrates, will be deployed in orbit as a Polar Orbital Experimental Module (Poem) — and carry out scientific experiments for the first time.

The final stage will use its own navigation command to maintain orbital altitude. It will also carry six additional payloads, including two from Indian private startups — Digantara and Dhruva Space. The latter two were facilitated by IN-SPACe.

This, though, is not the first time that Isro is using its fourth stage as an Earth orbital platform. Isro’s 2019 PSLV-C44 mission, launched in January 2019, became the first mission in the world to deploy a reusable final stage of a space mission. Taking this further, PSLV-C53 will now use the orbital platform to conduct experiments in space as well.

The C53 mission marks the launch of three satellites out of a planned five that Isro had targeted to launch by May this year. S Somanath, chief of India’s central space agency, said at the launch of the PSLV-C52 mission earlier this year that the agency plans to launch five satellites within three months.

Somanath had also said that through 2022, Isro plans to launch a total of 19 space missions — of which the C53 mission would be one.

PSLV-C53/DS-EO Mission

ISRO undertakes PSLV-C53/DS-EO mission on June 30, 2022. The launch is scheduled at 18:00 hours IST from the Second Launch Pad at Satish Dhawan Space Centre, Sriharikota. The countdown of 25 hours leading to the launch begins at 1700 hours IST on June 29, 2022.

PSLV-C53 is the second dedicated commercial mission of NewSpace India Limited (NSIL). It is designed to orbit DS-EO satellite along with two other co-passenger satellites from Singapore. This is the 55th mission of PSLV and 15th mission using PSLV-Core Alone variant. It is the 16th PSLV launch from the second launch pad. The mission proposes to demonstrate the utilization of the spent upper stage of the launch vehicle as a stabilized platform for scientific payloads subsequent to the separation of the satellites.

A four stage, 44.4 m tall PSLV-C53 has a lift-off mass of 228.433 t. It would inject DS-EO satellite into an orbit with semi-major axis of 6948.137 + 20 km, at an altitude of 570 km measured from the equator, with a low inclination of 10 deg. + 0.20.  PSLV-C53 carries three satellites. DS-EO, a 365 kg and NeuSAR, a 155 kg satellite both belonging to Singapore. Third satellite is a 2.8 kg Scoob-1 of Nanyang Technological University (NTU), Singapore.

PSLV Orbital Experimental Module (POEM)

DS-EO carries an Electro-Optic, multi-spectral payload that will provide full color images for land classification, and serving Humanitarian Assistance and Disaster Relief needs. NeuSAR is Singapore's first small commercial satellite carrying a SAR payload, which is capable of providing images in day and night and under all weather conditions. SCOOB-I satellite is the first satellite in the Student Satellite Series (S3-I), a hands-on student training program from the Satellite Research Centre (SaRC) at Singapore's NTU School of Electrical and Electronic Engineering.

The PSLV Orbital Experimental Module (POEM) activity is performs in-orbit scientific experiments using the spent PS4 stage as an orbital platform. It is first time that PS4 stage would orbit the earth as a stabilized platform. Attitude stabilization is achieved using a dedicated NGC system. POEM derives the power from the solar panels mounted around the PS4 tank and a Li Ion battery. It navigates using four sun sensors, a magnetometer, gyros & NavIC. It carries dedicated control thrusters using Helium gas storage. It is enabled with telecommand feature.

POEM carries six payloads including two from Indian Space Start-ups M/s Digantara and M/s Dhruva Space, enabled though IN-SPACe and NSIL.
