NASA reverses a decision made earlier in the month to cancel the asteroid-hopping Dawn mission, following appeals and assurances from the mission managers. Intended to use ion propulsion to visit to of the asteroid belt’s largest bodies, Dawn’s cancellation does have the effect of sliding the mission from a 2006 launch to a 2007 launch. The budget for the mission is expanded from $373,000,000 to $446,000,000, and arrival at its first target, the large asteroid Vesta, is still scheduled for 2011.
