NEW DELHI: Pushing dual use of its space rockets, Indian Space Research Organisation will not only launch three commercial foreign satellites with PSLV-C53 on June 30 but the rocket’s fourth and final stage will also double up as an orbital platform in space for six payloads, including two from desi space startups, Digantara and Dhruva Aerospace. The launch of PSLV-C53/DS-EO mission is scheduled at 6 pm from the second launchpad at Sriharikota and the countdown will start at 5pm on June 29.
PSLV-C53 is the second dedicated commercial mission of space PSU NewSpace India Limited (NSIL) and is designed to launch DS-EO satellite along with two other co-passenger satellites from ST Electronics, Singapore. The mission proposes to demonstrate the utilisation of the spent upper stage (PS4) of the launch vehicle as a stabilised platform for scientific payloads, subsequent to the separation of the satellites. It is the first time that the PS4 stage will orbit the Earth as a stabilised platform, an Isro statement said.
PSLV-C53 will carry the 365-kg satellite DS-EO and NeuSAR, a 155-kg satellite, both belonging to Singapore and built by Starec Initiative, South Korea. Third satellite is a 2.8 kg Scoob-1 of Nanyang Technological University (NTU), Singapore. While NeuSAR is Singapore’s first small commercial satellite carrying a SAR payload that 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.
PSLV orbital experimental module DS-EO carries an electro-optic, multi-spectral payload with 0.5 m resolution imaging capability.
