ESA’s unmanned Rosetta space probe, carrying the Philae lander bound for a 2014 rendezvous with Comet 67/P Churyumov–Gerasimenko, makes a gravity-assist flyby of planet Mars to alter its trajectory. As Rosetta will be only 160 miles from the Martian surface at its closest approach, the spacecraft is put into a safe mode for this critical part of its trip, and emerges unscathed. Its next gravity assist will come from Earth itself later in the year.
