ISRO's PSLV C21 rocket successfully blasted off into space on its 100th mission on a cloudy Sunday morning (09-09-12).
Prime Minister Manmohan Singh was among the cheering congregation of officials, scientists and media persons at the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh.

On this journey, the PSLV C21 rocket ferried two dollar-paying foreign passengers – a French Earth observation satellite Spot 6 and a Japanese micro satellite Proiteres into polar orbit.

On Sunday, precisely at 9.52 minutes, the rocket lifted off with a deafening roar and thick orange flame powering its upward spiralling journey, amid much cheers and claps from hundreds of special guests from the government, scientific community and media representatives. Located some 80km north of Chennai, Sriharikota hosts the Satish Dhawan Space Centre from where ISRO carries of all the launches of its rockets that put satellites into orbit.

Hundreds of people living in and around the space centre crowded onto rooftops for a live show of the rocket launch, as they have been doing for the past several years. While the people were on their rooftops, Prime Minister watched the historic event from ISRO’s mission control room as the PSLV rocket’s latest edition hurtled away from earth.

Within minutes, the 230 ton rocket was out of the eyesight of the people, its movement being tracked on giant computer screens. After one minute, the ground control said the first stage was normal and in two minutes the second stage started, which was also normal. In three minutes, heat shied was separated. Scientists at the control room were tracking the performance and relaying it over public address system as Prime Minister listened to it in rapt attention. Plus five minutes: PS3 performance normal.

The PSLV C21 was on its way to deliver Spot 6 and Proiteres into a 655km polar orbit inclined at an angle of 98.23 degrees to the equator. SPOT and Indian remote sensing satellites (launched earlier) are the two leading earth observation satellite series. SPOT 6 is the heaviest foreign satellite ever to have been launched by the ISRO, which has made launching satellites as a significant business activity earning precious foreign exchange to the country.

The PSLV C21 cost Rs. 75 crore to make.

More important, it has established the country as a major player in the satellite launching business, which started in 1999 as an additional baggage when ISRO launched India’s own satellite. So far, ISRO has launched 27 foreign satellites and the two of Sunday’s total up its tally to 29.

India is also a major player in the space with a the largest number of remote sensing satellites that send back imagery in a variety of spatial resolutions – from more than meter ranging up to 500 meters. This rich collection of data also makes India an important player in the data market.

India has 12 remote sensing/earth observation satellites circling the earth which makes it a leader in remote sensind data market. – The 12 satellites are :TES, Resourcesat 1, Cartosat 1, 2, 2A and 2B, IMS 1, Risat-2, Oceansat 2, Resourcesat-2, Megha-Tropiques and Risat-1.

Indian Space Research Organisation (ISRO) chief K. Radhakrishnan on Sunday hailed the country's momentous 100th space mission, through the launch of the Polar Satellite Launch Vehicle (PSLV-C21).

"This is the 100th space mission of India. Right from the days of Aryabhatta that was launched in the 1975 to now, we have 62 Indian satellites, one space recovery module and with today's PSLV 37 launch vehicle missions. So this is a major milestone in that respect," Radhakrishnan told media.

"Another milestone is that this is the heaviest customer satellite that has been launched on PSLV. You had seen two AVSR (audio-visual speech recognition) plates launched in dedicated missions of PSLV, but this is the heaviest. Not only that this is one of the world class remote sensing satellite built by France," he added.

Radhakrishnan also mentioned that prior to the PSLV-C21 launch, ISRO had undertaken 99 successful missions, including 62 satellites and 37 launch vehicles.

He also said that the proposed grand Mars project is going to be one more major milestone in the history of India's space research.

"More importantly, the Mars Orbiter Mission that had been announced on August 15 by the honourable Prime Minister, that is going to be another major milestone in that direction. Plus of course technology development, R andD (research and development), these are investment for the future," he said.

"Now coming to the money, soon we would get the indication from the Planning Commission as to what will be the allocations. So I can today talk about the missions that we have planned, allocations when we will get the money available for the Plan and what is available for the science and technology, maybe next time I will be able to tell the allocation," he added.

The space agency's old warhorse, the PSLV, blasted off into space at 9:51 a.m. with two foreign satellites from the spaceport of Sriharikota.

Prime Minister Dr. Manmohan Singh witnessed the launch of PSLV C-21, carrying French advanced remote sensing satellite 720 kg SPOT-6 and its 15 kg Japanese micro satellite PROITERES.

SPOT-6 is the biggest commercial lift so far since India forayed into the money-spinning commercial satellite launch services after 350kg Agile of Italy was put in orbit in 2007 by PSLV.

Twelve other foreign commercial satellites were less than 300 kg.

France's five earlier SPOT satellites were launched by European Araine rocket.

SPOT-6, built by ASTRIUM SAS,a subsidiary of EADS, France, is an earth observation satellite, while PROITERES, developed by students and faculty of Osaka Institute of Technology, will study Kansai region of Japanese island of Honshu
