India on Thursday night opened the year’s space campaign by putting into orbit defence imaging satellite”Microsat R” for the Defence Research and Development Organisation (DRDO) and students-built nano-satellite”Kalamsat” at a Duplicate book style.
The noteworthy facets of this space assignment are flying of a new version of Polar Satellite Launch Vehicle (PSLV), switching off and on of the fourth phase engine bunch of times, and use of fourth stage as an orbital platform carrying Kalamsat.
After the successful launch, ISRO Chairman K Sivan stated:”The assignment is a grand success. The PSLV rocket just injected the Microsat R from its designated orbit”
Sivan stated, this PSLV rocket isn’t an another PSLV rocket lot of invention have been integrated in it like the usage of aluminum tank in the fourth stage and using it as a orbital platform for the five member student group and Space Kidz India constructed nano-satellite Kalamsat.
He said, the Indian space agency is prepared to help all Indian pupils to conduct space experiments while ISRO would perform the research to get the benefit of the nation.
At 11.37pm, the 44.4-metre tall rocket blasted off by the first launch pad here.
With the ferocious orange flame in its tail lighting up the night skies, the rocket slowly gained pace and went up and up enthralling the people in the rocketport, with the rocket’s engine sound like a rolling thunder adding to the thrill.
More intriguing facet came in if rocket’s fourth-stage/ engine was cut/switched off just over 13 minutes following the lift-off.
A minute after the DRDO’s satellite satellite Microsat R was ejected in an altitude of about 277 km.
“There is increased demand for satellites out of strategic sectors.
The GSAT-7 and GSAT-7A are both dedicated military communication satellites, although all other ground monitoring and communication satellites launched earlier were of double use – defence and civilian.
The PSLV is a four-stage engine expendable rocket with switching solid and liquid fuel.
In its usual configuration, the rocket would have six strap-on motors hugging its first phase.
Nevertheless, the 44.4-metre tall rocket which lifted off Thursday had just two strap-on motors along with its configuration is designated as PSLV-DL.
At about 100 minutes after the lift-off, the rocket’s fourth stage was changed on again for few seconds until it was cut off.
In the end, at about 103 minutes after the rocket left the ground, the fourth stage began its function as an orbital platform carrying Kalamsat with an altitude of 450 kilometers.
Kalamsat is a payload developed by students and Chennai-based Space Kidz India and also the first to use the rocket’s fourth stage within an orbital platform.
The satellite price is about Rs 12 lakh.
