The 28hr countdown activity of PSLV-C40/Cartosat2 Series Satellite Mission has started at 05:29hr IST today, Thursday, January 11, 2018
PSLV-C40/Cartosat-2 Series Satellite Mission will be launched on Jan 12, 2018 at 09:28 Hrs (IST) from SDSC SHAR, Sriharikota.
The PSLV rocket, after a shocking falter four months ago, will return to the launch pad at Sriharikota on Friday.
A successful flight of PSLV-C40 is expected to put behind the Indian light lift rocket’s freak failure on August 31. During the forced hiatus, the Indian Space Research Organisation diagnosed why the nose cone of the previous C-39 rocket did not release the satellite; it took necessary corrective steps, officials said.
The launch is slated for 9.28 a.m. from the Satish Dhawan Space Centre in Andhra Pradesh. The countdown is set to begin Thursday morning.
Now among the world’s favourite and reliable commercial launchers for small satellites, the upcoming 42nd PSLV will carry a total of 31 satellites including 28 paid riders.
The main payload, the 710-kg Cartosat-2F, is the seventh in the Cartosat-2 series and is built to work for five years. Said to have a high, sub-metre resolution, it is unofficially said to serve military surveillance purposes.
The PSLV has so far launched 209 small and medium satellites for foreign countries and earned revenue for the commercial arm, Antrix Corporation Ltd.
ISRO will be trying a two-orbit feat with the PSLV for the second time. On Friday, just after 17 minutes from take-off, the main satellite will be released first into a 505-km orbit, followed by 29 others.
Almost 1.5 hours later, microsat will be released into a lower 359 km orbit. Between the two orbits, the engine in the fourth stage of the rocket will be re-started twice during the course.
The flight lasting 2 hours and 21 minutes will be the longest of the PSLV, about six minutes longer than C-35 which was launched in September 2016.
PSLV-C40/Cartosat-2 Series Satellite Mission PSLV-C40
India’s Polar Satellite Launch Vehicle, in its forty second flight (PSLV-C40), will launch the 710 kg Cartosat-2 Series Satellite for earth observation and 30 co-passenger satellites together weighing about 613 kg at lift-off. PSLV-C40 will be launched from the First Launch Pad (FLP) of Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota.
The co-passenger satellites comprise one Microsatellite and one Nanosatellite from India as well as 3 Microsatellites and 25 Nanosatellites from six countries, namely, Canada, Finland, France, Republic of Korea, UK and USA. The total weight of all the 31 satellites carried onboard PSLV-C40 is about 1323 kg.
The 28 International customer satellites are being launched as part of the commercial arrangements between Antrix Corporation Limited (Antrix), a Government of India company under Department of Space (DOS), the commercial arm of ISRO and the International customers.
Cartosat-2 Series Satellite
Cartosat-2 Series Satellite is the primary satellite carried by PSLV-C40. This remote sensing satellite is similar in configuration to earlier satellites in the series and is intended to augment data services to the users.
The imagery sent by satellite will be useful for cartographic applications, urban and rural applications, coastal land use and regulation, utility management like road network monitoring, water distribution, creation of land use maps, change detection to bring out geographical and manmade features and various other Land Information System (LIS) as well as Geographical Information System (GIS) applications.
