In its 32nd flight conducted from Satish Dhawan Space Centre (SDSC), SHAR, Sriharikota December 16 evening, ISRO’s Polar Satellite Launch Vehicle PSLV-C29 successfully put all the six satellites, including the 400 kg TeLEOS-1, the primary and Singapore’s first commercial earth observatory satellite, into an orbit of 549 km height inclined at an angle of 15 deg to the equator. The other five satellites were co-passenger payloads.
The six satellites carried by PSLV-C29 together weighed about 624 kg at lift-off. These six satellites were launched as part of the agreement entered into between ST Electronics (Satcom & Sensor Systems), Singapore and Antrix Corporation Limited, the commercial arm of the ISRO, a Government of India company under the Department of Space (DoS).
This is the eleventh flight of PSLV in ‘core-alone’ configuration (without the use of solid strap-on motors). PSLV has successfully launched 57 satellites so far for customers from abroad including the six Singapore satellites launched this evening (December 16, 201).
After a 59-hour smooth countdown, the 227.6 tonne PSLV-C29 lifted off from the First Launch Pad (FLP) at SDSC SHAR at 1800 hrs (6:00 pm) IST with the ignition of its first stage. The important flight events included the separation of the first stage, ignition of the second stage, separation of the payload fairing at about 117 km altitude, second stage separation, third stage ignition and separation, fourth stage ignition and cut-off.
Once the intended orbit was achieved, TeLEOS-1 was deployed at about 18 min 12 seconds after lift-off. This was followed by the deployment of other five satellites, viz, Kent Ridge-1, VELOX-C1, VELOX-II, Galassia and Athenoxat-1 in quick succession in the subsequent three minutes.
President Pranab Mukherjee has congratulated the Indian Space Research Organisation for the successful launch of PSLV-C29.
In a message to ISRO Chairman AS Kiran Kumar, the President said: “I extend my hearty congratulations to you and your entire team at the Indian Space Research Organisation for the successful launch of PSLV-C29. Along with two micro-satellites and three nano-satellites of Singapore, PSLV-C29 is carrying Singapore’s first commercial earth observatory satellite TeLEOS-1. Today’s achievement demonstrates, yet again, India’s increasing space capabilities.
Kindly convey my greetings to the members of your team of scientists, engineers, technologists and all others associated with this great mission. I wish the ISRO continued success in the coming years.”
Vice President Hamid Ansari in his congratulatory message said: I offer my congratulations to the scientists, engineers and technicians of the Indian Space Research Organisation for the successful launch of the of PSLV-C29 carrying six satellites.
The flawless launch has demonstrated once again India’s capabilities in the space sector. I wish ISRO all the very best for the future.
