Proba-3 is a highly under-publicized new space mission.

Two spacecraft will fly in formation to create solar eclipses on demand. The same basic technology could eventually lead to huge, virtual space observatories & to telescopes that can bring other Earths into view.

ESA’s double-satellite Proba-3 mission will be flying where no previous member of the Proba minisatellite family has gone before – up to 60 000 km away, a seventh of the way to the Moon. Set for launch in 2024, the two satellites will be launched together into a highly elliptical orbit, ranging from 600 km up to a high point of 60 000 km. For six hours per 19.5 hour orbit, the pair will line up so that the Occulter spacecraft casts a shadow upon the Coronagraph spacecraft to open up the Sun's corona atmosphere for sustained observation.

Proba-3 Technologies

A broad range of novel technologies are essential to make Proba-3 a success. The mission’s formation flying system includes components in both satellites, with a Formation Flying Management system being in charge of scheduling and planning formation …

PROBA-3

The ASPIICS (Association of Spacecraft for Polarimetric and Imaging Investigation of the Corona of the Sun) coronagraph on ESA's technology mission PROBA-3 (PRoject for On-Board Autonomy) introduces a new generation of these instruments.
