> Proba-3, works just like a real solar eclipse. One spacecraft, which is roughly circular when viewed from the front, orbits closer to the sun, and its job is to block the bright parts of the sun, acting as the moon would in a real eclipse. It casts a shadow on a second probe that has a camera capable of photographing the resulting artificial eclipse. > Having two separate spacecraft flying independently but in such a way that one casts a shadow on the other is a challenging task. But future missions depend on scientists figuring out how to make this precision choreography technology work, and so Proba-3 is a test. Oh wow, they've potentially rescued this (very cool!) mission for both probes | ||

Scott Manley had this nice overview of the mission (~9 min) | ||
