ISRO PSLV-C43 launch LIVE UPDATES: HysIS satellite key focus of C43 mission

ISRO PSLV-C43 launch in India today LIVE UPDATES: Here are more details around the PSLV launch vehicle, HysIS satellite, and launch status from the Satish Dhawan Space Centre in Sriharikota.

ISRO PSLV-C43 launch mission timings, launch payload LIVE UPDATES:

The Indian Space Research Organisation (ISRO) will launch its upcoming probe, PSLV-C43 within the next hour. This launch will take place from the first launch pad of the Satish Dhawan Space Centre in Sriharikota. Marking the 45th mission that uses the polar satellite launch vehicle (PSLV) rocket, ISRO will launch its latest Earth-mapping satellite, HysIS, as part of the mission.

The HysIS satellite adds a mass of 360kg to the payload and will be launched beside 30 other satellites from six nations. Out of these, 23 are from the United States. These smaller satellites will add a weight of 281.4kg to the payload and adds to ISRO’s list of 239 foreign satellites that have already been launched. While ISRO is only using the lightest version of the PSLV rocket, the core-alone PSLV, it is expected to be modified for future missions as the Indian space agency plans manned missions.

The mission director counts down the achievements of the PSLV missions as the countdown closes to within five minutes of launch. With the HysIS satellite, India will be able to estimate greater geological studies, as well as weather analysis, coastal studies and agricultural mapping of the Earth’s surface.

The mission director of the PSLV-C43 rocket has just confirmed that all operations and manoeuvres leading to the launch have been successfully put in place, and has given his consent for the launch to carry on as planned.  Given the status of the mission, the PSLV launch sequence will begin from 9:57:30, which is 30 seconds before the rocket’s final launch.

The key part of the PSLV-C43 mission is the HysIS satellite, that will further India’s earth-mapping abilities. Designed around the ISRO Mini Satellite-2 (IMS-2) bus, the satellite has a weight of 360kg, that can be easily handled by the core-only PSLV model. This will make observations within the electromagnetic spectrum, among the visible, near infrared and far infrared bandwidths. Its studies will create improvements in agriculture, coastal surveillance, weather monitoring and more.

ISRO has confirmed in its live updates for the mission that PSLV-C43 will be launched at 9.58am, instead of the 9.30am timing that had been decided earlier. While the delay is not expected to make any changes to the launch, it can be considered a safeguard from India’s space agency, that aims to independently send men into space in the coming years. The countdown for PSLV-C43 has been marked from 5:48 am this morning.

The PSLV-C43 mission will carry a total payload of 461.5kg, made up of 29 nanosatellites, one microsatellite, as well as the HysIS imaging satellite. Of those, the latter, with a five-year mission, is expected to give a deeper understanding of climate change, weather phenomena, ocean currents and more. It is also expected to set the base for manned missions, as ISRO plans a rocket to send men to the Moon.

HysIS, short for hyperspectral imaging satellite, will make its observations by studying the effects of the Earth’s surface under the visible, near infrared, and far-infrared bands of the electromagnetic spectrum. This will help it track various events on Earth, without disturbance from electric discharges from the upper atmosphere. It will maintain a polar sun-synchronous orbit, which will keep the satellite’s position constant with respect to the Sun, which will maintain its path according to the Earth’s rotation and revolution.
