VoyagerThe unmanned robotic Voyager 1 space probe lifts off on a voyage to Jupiter, Saturn and beyond, taking advantage of a once-in-175-years alignment of the planets in the outer solar system. Originally designated Mariner 11, one of many planned space probes in the now greatly scaled-back Mariner Jupiter/Saturn ’77 program, Voyager 1 is also the first spacecraft to take a picture of the Earth and its moon from beyond the moon’s orbit, and will become the first human-made object to leave Earth’s solar system.
