ISRO's PROBA-3: The Indian Space Research Organisation (ISRO) launched PROBA-3 spacecraft PSLV-C59/PROBA-3 from Satish Dhawan Space Centre, Sriharikota, today.
According to ISRO's update, the spacecraft was successfully launched, marking a landmark moment in history which saw the collaboration between ISRO and NewSpace India Limited (NSIL), and the European Space Agency (ESA).
Initially, the Bengaluru-headquartered space agency planned to launch ESA's Proba-3 at 4.08 pm on December 4 from the spaceport. However, after ESA requested to re-schedule the lift-off minutes before the planned time due to an anomaly detected in the satellite propulsion system, ISRO postponed the launch of PSLV-C59/PROBA-3 to December 5, 4.04 pm.
Keys details of the successful launch of ESA’s PROBA-3 satellites:
According to a PTI report, the PSLV-C59 rocket stands 44.5 metres tall and ventured on its 61st flight. With the PSLV-XL, it is the spacecraft's 26th flight.
ISRO in a post on X said, “Liftoff Achieved! PSLV-C59 has successfully soared into the skies, marking the commencement of a global mission led by NSIL, with ISRO’s technical expertise, to deploy ESA’s groundbreaking PROBA-3 satellites.”
It added, “A proud moment celebrating the synergy of international collaboration and India’s space achievements.”
The Proba-3 spacecraft consists of two satellites and aims to move to a highly elliptical orbit that extends over 60,000 kilometres from Earth. Coronagraph (310kg) and Occulter (240kg) are the two satellites onboard, which will study the Sun's outer atmosphere, Corona.
Notably, this is the first time ESA has partnered with ISRO for a satellite launch in 23 years. The last collaboration was during the Proba-1 Earth observation mission in 2001. By leveraging ISRO’s cost-effective yet reliable PSLV platform, the two satellites would undertake an 18-minute journey to reach the desired orbit.
