Isro gears up for commercial launch of 2 UK satellites
NEW DELHI: The Indian Space Research Organisation (Isro) on Saturday began a 33-hour countdown to the launch of two United Kingdom (UK) satellites from the Satish Dhawan Centre in Sriharikota.
The satellite launch, scheduled for 10:00pm on Sunday, will be part of Isro’s commercial mission under the space agency’s Antrix Corporation Limited. The mission will carry two small earth observation satellites, Novasar and S1-4, weighing a total of 889 kg into a 583- km sunsynchronous orbit.
S1-4 is a high-resolution optical earth observation satellite, which will improve UK’S disaster monitoring capabilities. Novasar carries a Synthetic Aperture Radar that can be used for mapping the earth surface
The satellites will be carried aboard Isro’s workhorse, the Polar Satellite Launching Vehicle (PSLV - C42), which has launched 52 Indian and 237 commercial international satellite in the span of 25 years. This mission will use the lightest core-only configuration of PSLV, which does not have the six additional solid-strap on motors.
The mission comes after a five-month hiatus following the launch of the seventh satellite (IRNSS 1I) in India’s regional navigational satellite constellation— NAVIC— in April.
