View of the Earth and our Moon as seen from Mars looking past the Sun on 5 December 2008. Earth is the large-ish dot just to the right of the Sun's atmosphere. This image clearly illustrates the path that line-of-sight radio signals must travel - through the Sun's turbulant atmosphere - between Mars Express and the Earth.
