WSJ: Sun-powered plane completes California test flight

Roger Linfield and his colleagues at the Jet Propulsion Laboratory in Pasadena, California, who are in charge of the mission, aim to show that spacecraft flying in formation can be controlled so precisely that the distance between them varies by only a tiny fraction of a wavelength of light.
