Bengaluru: The countdown for the launch of Polar Satellite Launch Vehicle (PSLV-C43)– the earth observation satellite Hyper Spectral Imaging Satellite (HysIS) along with 30 other satellites from eight countries began at 5:58 AM Wednesday.
With just 28 hours to go, the launch has been scheduled at 9:58 AM on Thursday from the Satish Dhawan Space Centre (SDSC) SHAR at Sriharikota in Andhra Pradesh, said the Indian Space Research Organisation (ISRO).
ISRO said in its statement, “The countdown for the launch of PSLV-C43/HysIS mission started today at 05:58 hrs IST…” The space agency further said that fuel filling of the PS4 stage– fourth stage has been completed.
The HysIS which was developed by ISRO is the primary satellite of the PSLV-C43 mission. The mass of the spacecraft is about 380 kg, the space agency said adding that the satellite would be placed in 636 km-polar sun-synchronous orbits with an inclination of 97.957 degrees.
HysIS, whose mission life is five years, studies the earth’s surface in visible near infrared and shortwave infrared regions of the electromagnetic spectrum.
The co-passengers of HysIS include 1 micro and 29 nanosatellites from eight different countries. All these satellites have been commercially contracted for launch through ISRO’s commercial arm Antrix Corporation Limited. All the satellites would be placed in a 504 km orbit by PSLV-C43, said ISRO.
This will be ISRO’s second launch in the month. The space agency had launched its latest communication satellite GSAT-29 on board GSLV MkIII-D2 on November 14.
The PSLV is a four-stage launch vehicle with alternating solid and liquid stages. PSLV-C43, which is the 45th flight of the PSLV, is the ‘Core Alone’ version of PSLV. It is the lightest version of the launch vehicle.
