Mars by Rosetta

On February 24, 2007, the ESA’s Rosetta spacecraft passed by Mars, the second of four planetary gravity-assist flybys on its long way to a 2014 rendezvous with comet Churyumov-Gerasimenkoy, getting close enough to take some very detailed pictures. That data wasn’t initially released by the mission leader, but they were finally made available late last year, including this frame-filling photo of Mars that Rosetta took as it approached the planet, using its main science camera, OSIRIS.
