Dawn :Dawn is a retired space probe launched by NASA in September 2007 with the mission of studying two of the three known protoplanets of the asteroid belt, Vesta and Ceres. Dawn/FC :The Framing Camera (FC) is a German contribution to the Dawn mission, to map Vesta an Ceres through a clear filter and 7 band-pass filters covering the wavelengths from the visible to the near-IR.id:Dawn/FC.a |
