- NASA‘s Deep Impact extended mission for their spacecraft is starting as an extended mission called Epoxi. History was made when Deep Impact directed an impactor from the spacecraft into the comet Tempel 1 on July 4th of 2005. Only recently did NASA extend the mission. They’ve redirected the spacecraft for a flyby of comet Hartley 2 on October 11th, 2010. Five nearby starts with “transiting exosolar planets,” so named because the plant moves in front of its star, will also be studied. University of Maryland astronomer Michael A’Hearn directed the spacecraft to start these observations on January 22nd. Some 2000 plus exosolar planets have been discovered to date.
