The European Space Agency’s Proba-3 mission was scheduled to be launched today on ISRO’s Polar Satellite Launch Vehicle from the Satish Dhawan Space Centre
Due to an anomaly detected in Proba-3 spacecraft, the PSLV-C59/PROBA-3 launch has been rescheduled to Thursday (December 5, 2024), the Indian Space Research Organisation (ISRO) said on Wednesday (December 4, 2024).
The much-anticipated launch of the European Space Agency’s (ESA) Proba-3 mission, initially scheduled for December 4, 2024, has been delayed due to an anomaly detected in the Proba-3 spacecraft.
The much-anticipated launch of the European Space Agency’s (ESA) Proba-3 mission, initially scheduled for December 4, 2024, has been delayed due to an anomaly detected in the Proba-3 spacecraft. The Indian Space Research Organisation (ISRO) officially announced on December 4 that the PSLV-C59/PROBA-3 mission will now be rescheduled to Thursday, December 5, 2024. The mission will be launched from the Satish Dhawan Space Centre in Sriharikota, India, using the trusted Polar Satellite Launch Vehicle (PSLV) rocket.
The PSLV-C59/PROBA-3 mission will be the 61st flight of the PSLV series and the 26th mission using the PSLV-XL configuration. This mission is critical as it will carry ESA’s Proba-3 satellites, each weighing approximately 550 kg, into a highly elliptical orbit. The primary aim of this mission is to demonstrate the concept of precision formation flying in space. The Proba-3 mission will focus on using two satellites that will fly together in perfect synchronization, essentially functioning as a single rigid structure despite being two separate spacecraft.
Precision Formation Flying and Rendezvous Technology
Proba-3 will be the world’s first mission to perform precision formation flying, which involves one satellite holding its position with a precision of just a millimetre in relation to the other. ESA describes the mission as a pioneering project, where the two satellites will maintain a fixed configuration, flying closely together at a distance of around 150 meters. The satellites will demonstrate the ability to line up perfectly, with one spacecraft shadowing the other, a feat that will test the advanced rendezvous technologies required for future space missions.
The technology behind Proba-3 is essential for a variety of future scientific and commercial applications, including large-scale space observatories and solar power generation in space. By demonstrating formation flying with such precision, Proba-3 will pave the way for missions that rely on the coordination of multiple spacecraft to achieve complex goals, such as space-based telescopes and communication networks.
The spacecraft anomaly that led to the postponement of the launch is being actively addressed by the team at ISRO and ESA. The two organizations are working together to resolve the issue and ensure that the mission can proceed as planned on the new launch date. Despite this delay, both ISRO and ESA remain confident that the Proba-3 mission will be a success and will provide valuable insights into the future of space exploration.
A New Chapter in Space Exploration
The Proba-3 mission is part of ESA’s larger commitment to advancing space technologies and pushing the boundaries of what is possible in the realm of space science. The success of this mission will mark a significant achievement in precision space operations, laying the groundwork for future missions that could involve multiple spacecraft working in tandem to conduct complex scientific experiments and other high-tech applications
