ISRO announced that it will be launching - the second dedicated commercial mission of its commercial arm NewSpace India Limited (NSIL) - 'PSLV-C53' carrying three satellites from Singapore on June 30.
The launch vehicle carrying DS-EO satellite along with two other co-passenger satellites is scheduled to lift off at 6:00 pm from the Second Launch Pad at Satish Dhawan Space Centre in Sriharikota. The countdown of 25 hours leading to the launch begins at 5:00 pm on June 29.
The mission, which is designed to orbit DS-EO satellite along with two other co-passenger satellites from ST Electronics, Singapore, 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, according to news agency PTI.
This will be the 55th mission of PSLV and 15th mission using the PSLV-Core Alone variant, and is the 16th PSLV launch from the second launch pad.
A four stage, 44.4 m tall PSLV-C53 has a lift-off mass of 228.433 t, and 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 100+ 0.20.
The three satellites are- DS-EO, a 365 kg and NeuSAR, a 155 kg satellite both belonging to Singapore and built by Starec Initiative, Republic of Korea, and the third satellite is a 2.8 kg Scoob-1 of Nanyang Technological University (NTU), Singapore.
The PSLV Orbital Experimental Module (POEM) activity performs in-orbit scientific experiments using the spent PS4 stage as an orbital platform, ISRO said, it is the first time that the PS4 stage would orbit the earth as a stabilized platform, reported PTI.
POEM carries six payloads including two from Indian Space Start-ups M/s Digantara and M/s Dhruva Aerospace, enabled though IN-SPACe and NSIL.
