PROBA-3 is the next mission in the PROBA line of small technology demonstration satellites of ESA. PROBA-3, to be launched in 2020, is a mission dedicated to the inflight demonstration of precise formation flying techniques and technologies. The PROBA-3 mission will place two small satellites in a highly elliptical orbit around the Earth. The two spacecraft will fly in a precise formation, producing a very long baseline solar coronagraph called ASPIICS (Association of Spacecraft for Polarimetric and Imaging Investigation of the Corona of the Sun). One spacecraft will carry the optical telescope, and the second spacecraft will carry the external occulter of the coronagraph. The inter-satellite distance of around 150 m will allow observing the inner corona close to the solar limb with very low straylight. The scientific objectives of PROBA-3 will be discussed in the context of other future solar and heliospheric space missions.
