NASA has officially declared the end of the mission of the Deep Impact space probe. On July 4, 2005, an impactor launche by the probe hit the nucleus of comet Tempel 1 in order to analyze its debris but it was also used to study other comets and for the observation of exoplanets. Last month, NASA lost communications with Deep Impact and after a month of failed attempts to establish them again the agency had to declare the end of the mission.
