Beschreibung : Unmanned space mission using the existing Deep Impact vehicle to begin a new series of observations. It performed a close approach to the comet 103P/Hartley, passing to within 694 kilometers (431 mi) of this small comet. The flyby speed was 12.3 km/s.
Early results of the observations show that the comet is powered by dry ice, not water vapor as was previously thought.The images were clear enough for scientists to link jets of dust and gas with specific surface features.
