A few weeks ago, a press release from the Opportunity mission celebrated Opportunity's surpassing of the previous NASA off-world driving record. That record was set in December 1972 by the Apollo 17 astronauts aboard their Lunar Roving Vehicle.

ESA celebrated the tenth anniversary of Mars Express' launch with a several-day science meeting during which they issued lots of press releases and numerous spectacular photos. My favorite of them all is this enormous image of Kasei Valles on Mars.
