India on Thursday night opened the year’s space campaign by putting into orbit defence satellite”Microsat R” for the Defence Research and Development Organisation (DRDO) and students-built nano-satellite”Kalamsat” in a Duplicate book style.
The noteworthy aspects of this space mission are flying of a new variant of Polar Satellite Launch Vehicle (PSLV), switching off and on of the fourth phase engine bunch of occasions, and use of fourth stage as an orbital stage carrying Kalamsat.
After the successful launching, ISRO Chairman K Sivan said:”The assignment is a grand victory. The PSLV rocket precisely injected the Microsat R in its designated orbit”
Sivan said, this PSLV rocket is not another PSLV rocket lot of innovation have been incorporated in it such as the use of aluminium tank in the fourth phase and utilizing it as an orbital platform for its five member student group and Space Kidz India constructed nano-satellite Kalamsat.
He explained, the Indian space agency is prepared to assist all Indian pupils to conduct space experiments while ISRO would perform the study for the benefit of the nation.
In 11.37pm, the 44.4-metre tall rocket blasted off from the first launching pad here.
With the ferocious orange flame at its tail light up the night skies, the enemy slowly gained pace and went up and up enthralling the folks at the rocketport, with the rocket’s engine noise like a rolling thunder adding to the thrill.
More thrilling aspect came in if rocket’s fourth-stageengine was cut/switched off just over 13 minutes after the lift-off.
A minute after the DRDO’s imaging satellite Microsat R was ejected at an altitude of about 277 km.
“There is increased need for satellites out of strategic sectors.
The GSAT-7 and GSAT-7A will be the two dedicated military communication satellites, while the rest of the ground monitoring and communication satellites launched earlier were of dual use – defence and civilian.
The PSLV is a four-stage engine expendable rocket with alternating solid and liquid gas.
In its usual configuration, the rocket would have six strap-on motors hugging its first stage.
Nevertheless, the 44.4-metre tall rocket that lifted off Thursday had just two strap-on motors and its configuration is designated as PSLV-DL.
At about 100 minutes following the lift-off, the rocket’s fourth period was switched on again for several seconds until it was again cut off.
Finally, at about 103 minutes after the rocket left the earth, the fourth phase began its function as an orbital platform carrying Kalamsat at an elevation of 450 km.
Kalamsat is a payload developed by students as well as Chennai-based Space Kidz India and also the first to utilize the rocket’s fourth stage within an orbital platform.
The satellite price is about Rs 12 lakh.
