It is a difficult business to design, build, successfully launch and then operate spacecraft on other worlds. Accomplishing the mission is particularly difficult for planetary probes, which go through significant atmospheres, collecting data on their way to the surface and, due to the challenges of the extreme environments associated with such destinations, often only survive for relatively brief periods once they have landed. ...

NASA's New Horizon's space probe was pointed toward Pluto and the frozen, sunless reaches of the solar system on a nine-year journey after getting a gravity boost Wednesday from Jupiter. The fastest spacecraft ever launched was within a million and a half miles of Jupiter early Wednesday, giving scientists a close-up look at the giant gaseous planet and its moons.
