NASA reported a successful start of Dawn's ion thruster engines and the craft began moving away from Vesta at a steadily increasing rate. Due to the efficiency of Dawn's engines, it will only use 250 pounds of fuel. The ion engines produce very little thrust but they can be run for extended periods which will allow Dawn to reach Ceres in just two and a half years which would be impossible with standard chemical rocket engines.
