ESA’s Proba-3 starts turning artificial eclipses into a new tool for solar science

The European Space Agency says Proba-3 has demonstrated precision formation flying and begun producing early science results by creating on-demand solar eclipses in space to study the corona and the origins of space  응

Key Takeaways

ESA’s Proba-3 uses two spacecraft flying 150 meters apart to create artificial solar eclipses.
The mission has already gathered 250 hours of high-resolution coronal video across 57 eclipses.

Proba-3’s Eclipse Observations Suggest the Sun’s Slow Wind Starts Much Faster Than Expected

Images from ESA’s Proba-3 mission indicate that slow solar wind in the inner corona can travel three to four times faster than scientists had expected, offering a new look at one of solar physics’ hardest regions to see.

Key Takeaways

ESA’s Proba-3 mission observed slow solar wind gusts moving three to four times faster than expected in the inner corona.
The mission uses two spacecraft flying in formation to simulate a solar eclipse.
