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, 1/7th of the way to the Moon.
Set for launch in 2019, Proba-3’s paired satellites will manoeuvre relative to each other with millimetre precision, intended to serve as the virtual equivalent of a giant structure in space – opening up a whole new way of running space missions… See http://www.esa.int/spaceinimages/Images/2016/07/Proba-3
