The Indian Space Research Organisation (ISRO) is preparing for the much-anticipated launch of the PSLV-C59/PROBA-3 mission, set to take place on Thursday, 5th December 2024, at 4:04 p.m.
The mission will utilise the Polar Satellite Launch Vehicle (PSLV-C59) to deploy the PROBA-3 satellites into a highly elliptical orbit. This launch is a dedicated commercial mission under NewSpace India Limited (NSIL).
The original launch date was postponed due to an anomaly detected in the PROBA-3 spacecraft. The new schedule has been announced, and countdown activities are underway at the Satish Dhawan Space Centre in Sriharikota. ISRO shared updates on social media, encouraging enthusiasts to stay tuned for this landmark event.
The PSLV-C59 mission represents a joint initiative between ISRO and NSIL. It is also a significant collaboration with the European Space Agency (ESA), making PROBA-3 a groundbreaking technology demonstration mission.
As the world’s first precision formation-flying mission, PROBA-3 will consist of two satellites flying in a fixed configuration as though they were part of a single rigid structure.
This mission aims to pioneer formation-flying and rendezvous technologies while conducting a large-scale scientific experiment.
The ESA has highlighted the mission’s potential for scientific and technological advancement. The two satellites, positioned approximately 150 metres apart, will form a solar coronagraph to observe the Sun’s faint corona near the solar rim, achieving a feat previously unattained.
The mission will also validate advanced metrology sensors and control algorithms, furthering innovation in orbital laboratory operations.
This experiment will serve as a critical milestone in studying the Sun’s outer atmosphere and demonstrate precise positioning techniques for spacecraft.
The dual-satellite system will adopt a fixed alignment, with one satellite blocking the Sun’s bright disk while the other captures detailed views of the corona. These observations could unlock significant insights into solar dynamics and space weather.
ISRO’s PSLV-C59 launch vehicle, known for its reliability, is designed to handle a total payload mass of around 320 tonnes. The rocket will follow its four-stage launch sequence to successfully place the satellites in orbit.
The mission also underscores ISRO’s growing capabilities in international collaborations and commercial space ventures.
The PROBA-3 mission is regarded as an “In-Orbit Demonstration” project by ESA, aimed at showcasing technologies critical to future space exploration. Beyond its scientific objectives, the mission will act as a testbed for acquisition, rendezvous, and proximity operations.
By validating these techniques, the mission is expected to pave the way for innovative methods of mission control and satellite deployment.
The launch has generated significant excitement within the global space community, as it promises to be a defining moment for both ISRO and ESA.
Updates from ISRO on platforms such as X (formerly Twitter) have kept the public engaged, building anticipation for this historic event.
The collaboration between India and Europe in the PROBA-3 mission not only highlights advancements in space technology but also reinforces the importance of international partnerships in pushing the boundaries of human knowledge.
