The Indian Space Research Organisation's space mission for the European Space Agency has lifted-off successfully. The Probe-3 spacecraft saw lift-off from the Satish Dhawan Space Centre at Sriharikota, Andhra Pradesh.
The mission, which was scheduled for launch on December 4, was postponed to December 5 after an anomaly was detected in the satellite propulsion system.
The Proba - Project for Onboard Anatomy - is named after the latin word meaning “let's try”. initiative from ISRO and the ESA will be the first space initiative to demonstrate flying in a precise formation down to a single millimetre to study the Sun's outer atmosphere - the Corona.
As per ISRO, the rocket has completed all three stages of launch and has entered the coasting stage. In the fourth stage of the launch, the rocket will be steered towards its destination - the orbit.
PSLV-C59, the rocket is expected to place the satellites into a highly elliptical orbit 18 minutes after lift-off.
🌟 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.🌍 A proud moment celebrating the synergy of international…
— ISRO (@isro) December 5, 2024 All About The MissionThe aim of the ISRO-ESA mission is to demonstrate precise formation flying and study the atmosphere of the Sun.
Proba-3 consists of two satellites - Coronagraph (310kgs) and Occulter (240kgs), which will fly together as one unit, 150 metres apart from each other.
As per the European Space Agency, Proba-3 will provide insights on the Corona, the outer atmosphere of the Sun, which is reportedly hotter than the Sun itself.
As per ESA and ISRObetjili, the instruments on the satellites will take close to six hours at a time to reach the solar rim and will then commence a 19-hour orbit around the Earth.
