The 100th Indian space mission was a grand success with an Indian rocket
 blasting off carrying two foreign satellites from Sriharikota. 
On a cloudy Sunday morning, the Polar Satellite Launch Vehicle-C21 
(PSLV-C21) blasted off carrying two satellites from the first launch pad
 at the Satish Dhawan Space Centre. 
On the terrace of the media centre, a large contingent of media persons 
cheered the entire journey of the rocket till it vanished into the 
clouds. 
At 9.53 a.m., the PSLV-C21, 44 metres tall and weighing 230 tonne, 
launched the French earth observation satellite SPOT 6 along with a 
micro-satellite from Japan into a 635-km polar orbit. PSLV-C21 is the 
eighth flight of PSLV in “core-alone” configuration (without solid 
strap-on motors). This is the 22nd consecutive time that a PSLV rocket 
has taken a satellite. 
Coming out behind the lush green trees, the rocket with orange flame in 
the tail burst in to the sky amid cheers of scientists in the control 
room and the media team assembled at the terrace of the launch centre.
After 18 minutes into the flight, PSLV-C21 delivered SPOT 6 and a few 
seconds later Proiteres into their intended polar orbit. Prime Minister 
Manmohan Singh along with Minister in Prime Minister’s Office V. 
Narayanasamy witnessed the launch. 
There was a two-minute delay in the launch due to impact of possible 
debris in space, K. Radhakrishnan, Chairman, Indian Space Research 
Organisation (ISRO), told newspersons later. 
With a lift off of 712 kg, SPOT 6 is the heaviest satellite to be 
launched by PSLV for an international customer. The Japanese 
micro-satellite Proiteres, carried as an auxiliary payload, has a lift 
off mass of 15 km. The cost of the rocket was Rs 90 crore. “We have 
recovered the project cost,” he said without giving details. 
SPOT 6 is a French Earth Observation Satellite capable of imaging the 
earth with a resolution of 1.5 metre. This latest generation optical 
remote sensing satellite is built by Astrium SAS, a leading European 
space technology company. 
Proiteres, on the other hand, is intended to study powered flight of a 
small satellite by an electric thruster and observe Kansai district in 
Japan with a high resolution camera. 
ISRO has sent 29 foreign satellites successfully to the orbit, including
 today’s launch. 
The successful launch of SPOT 6 would make ISRO’s PSLV rocket a strong 
contender to carry SPOT 7 planned by Astrium SAS soon, said 
Radhakrishan. India has one of the largest constellations of remote 
sensing satellites in the world providing imagery in a variety of 
spatial resolutions ranging over a metre to 500 metre. With 12 remote 
sensing/earth observation satellites orbiting in the space, India has 
proved its capability in the remote sensing data market. 
A cheerful Prime Minister later addressing scientists at the mission 
control room said today’s “launch is a milestone in our nation’s space 
capabilities”. 
The launch of these satellites on board an Indian launch vehicle is 
testimony to the commercial competitiveness of the Indian space industry
 and is a tribute to Indian innovation and ingenuity, he said.
