The European Space Agency's Proba-3 mission involves two separate satellites flying in a precise formation; what are these two spacecraft named?

Explanation

Coronagraph and Occulter. The Proba-3 mission consists of two satellites—Coronagraph and Occulter — flying about 150 meters apart in precise formation. The Occulter blocks the Sun’s bright disk, creating an artificial eclipse, while the Coronagraph observes the faint solar corona.
