After its 17 month long journey through space NASA’s mission DAWN is expecting a change of pace: On Wednesday, February 18th, the probe will swing-by Mars in order to pick up speed and correct its course. For the cameras aboard DAWN that were build under the leadership of the MPS this is the first and last rehearsal. Until the space probe reaches its first scientific goal, the asteroid Vesta, in 2011 there will be no comparable opportunity to test the instruments.
