The Indian Space Research Organisation (ISRO) is all set to launch PSLV-C53 on Thursday, June 30. The rocket will be carrying DS-EO and two other co-passenger satellites. The launch is scheduled at 18:00 hours IST (6 PM) from the Second Launch Pad at Satish Dhawan Space Centre, Sriharikota. Taking to its official Twitter handle ISRO informed, "PSLV-C53 is scheduled to launch DS-EO & 2 other co-passenger satellites on June 30, 2022, at 18:00 hrs IST from the 2nd Launch Pad, SDSC-SHAR, Sriharikota. It accompanies PSLV Orbital Experimental Module (POEM) orbiting the earth as a stabilized platform."

ISRO on Wednesday, June 29 also informed that the countdown leading to the launch today has commenced and the launch would be streamed live on ISRO website or ISRO Official Youtube channel ( from 17:32 hours IST (5:32 PM) today. "PSLV-C53/DS-EO Mission: The launch would be streamed LIVE on ISRO website or ISRO Official Youtube channel ( from 17:32 hours IST on June 30, 2022," the tweet read.

Meanwhile, people who are not much aware of the PSLV-C53/DS-EO Mission can check the details about the rocket below:

According to the information provided by ISRO, PSLV-C53 is the second dedicated commercial mission of NewSpace India Limited (NSIL). 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 100 + 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," ISRO said in a statement.

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 performed 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 through IN-SPACe and NSIL.
