ESA Proba-3 Contact Loss Disrupts Solar Mission
ESA Proba-3 Contact Loss has raised concerns among scientists after a major technical issue affected the mission designed to study the Sun’s outer atmosphere.

The European Space Agency is facing a setback as it lost contact with one of the two spacecraft in the Proba-3 mission. The issue started in February 2026 when a technical anomaly caused the Coronagraph spacecraft to lose its orientation in space.
This loss of control meant that the satellite could no longer keep its solar panels facing the Sun. Without enough sunlight, the battery drained quickly, forcing the spacecraft into survival mode. In this mode, only basic systems work, and communication with Earth stops.
How the Mission Works
The Proba-3 mission is unique because it uses two spacecraft working together. One is the Coronagraph, and the other is the Occulter. These two satellites fly about 150 metres apart in space.
The Occulter blocks the bright light of the Sun, creating an artificial solar eclipse. This allows the Coronagraph to capture clear images of the Sun’s corona, which is usually difficult to observe.
ESA Proba-3 Contact Loss: Recovery Efforts Underway
Scientists are now trying to restore contact with the Coronagraph spacecraft. The Occulter satellite is still working normally and may be moved closer to check the position of the damaged spacecraft.
This step could help engineers understand the problem and find a way to recover the mission. Before this issue, the Proba-3 mission had already completed over 60 successful formation-flying orbits.
Why Studying the Sun’s Corona Matters
The Sun’s corona is the outermost layer of the Sun’s atmosphere. It plays an important role in space weather, including solar winds and powerful eruptions.
These events can affect satellites, communication systems, and even power grids on Earth. By studying the corona, scientists hope to improve space weather predictions and protect modern technology.
Despite the setback, the Proba-3 mission remains an important step in advancing space research and satellite coordination technology.
