Earlier this month ESA’s Rosetta spacecraft had a first look at asteroid 21-Lutetia, one of the targets of its long mission. The onboard camera OSIRIS imaged the asteroid passing through its field of view during the spacecraft’s gradual approach to Mars. The planet will be reached on February 25, 2007, for the mission’s next gravity assist.
