Sriharikota, (AP): India successfully launched its latest earth observation satellite EOS-01 and nine international customer spacecraft on board a Polar rocket from the spaceport here on Saturday, in its first mission this year amid the COVID-19 pandemic.
The Indian Space Research Organisations workhorse Polar Satellite Launch Vehicle (PSLV-C49) injected EOS-01, intended for applications in agriculture, forestry and disaster management support and other satellites one by one in orbit around 20 minutes after lift-off from the Satish Dhawan Space Centre (SDSC), about 110 km from Chennai, at 3.12 pm.
This is ISROs first mission this year after the COVID-19 pandemic induced lockdown ‘disturbed 10 missions being planned by the agency and the nine customer satellites are from the USA, Lithuania and Luxembourg.
ISRO Chairman K Sivan described the mission as a “success” and termed it as “unusual” for ISRO as a rocket launch cannot happen like ‘work from home’ and all engineers and technicians had to travel from different centres and work together at Sriharikota for rocket launches.
“Today, I am extremely happy to declare that PSLV-C49 successfully placed earth observation satellite EOS-01 as well as nine customer satellites precisely into 575 kms orbit” he said at the mission control centre.
Subsequent to the successful launch, the primary satellite commenced operating its own functions including deployment of solar panels, Sivan said.
In view of the pandemic, ISRO implemented precautions for COVID-19 and scientists, mission directors, project directors, were seen with face masks and maintaining social distancing at the mission control centre.
There was no gathering of media persons and the public viewing gallery too was closed.
ISRO made arrangements for live telecast of the launch through various platforms, including its website and social media sites.
In a text book sequence, the four stage 44.5-metre tall PSLV-C49, in its 51st flight, blasted off from the first launch pad of SDSC at 3.12 pm at the end of the 26-hour countdown and soared into the sky.
The launch, originally scheduled for 3.02 PM, was delayed as the scientists around 15 minutes before lift-off “decided to put on hold following debris on the path of the rocket and inclement weather conditions.”
After the 10 minute delay, the rocket blasted off amid heavy rain leaving a trail of orange fumes before vanishing into thick clouds over the spaceport.
After a flawless flight with all four stages performing as programmed, the rocket first injected primary satellite EOS-01 into orbit around 15 minutes after lift off, followed by the customer spacecraft as the mood at the mission control centre turned jubilant with scientists breaking into cheers.
PSLV Mission Director S R Biju announced that all the 10 satellites were separated and were placed into desired orbits.
“PSLV-C49/EOS-01 mission is fully accomplished”, he said amid loud cheers from fellow scientists at the centre. Noting that today’s mission was “very special”, “very unusual” for ISRO, Sivan congratulated the ISRO team, who had to reach here from different centres amid the pandemic and said the EOS-01 satellite team and those behind the nine satellites would now take care of the rest of the mission. Besides human resources, he also referred to availability of ‘hardware’ for the launch as they had to be transported ‘carefully’ from various parts of the country to Sriharikota.
