 |  Rosetta at asteroid Lutetia
 10 July 2010
ESA’s comet mission Rosetta performed a fly by at asteroid Lutetia. In the weeks before closest
approach optical navigation was used together with Delta-DOR measurements to determine the motion
of the spacecraft relative to the asteroid whose orbit is known with very limited accuracy. Asteroid
Lutetia was revealed as a battered world of many craters. Rosetta returned the first close-up images of
the asteroid showing it is most probably a primitive survivor from the violent birth of the Solar System.
