Voyager 1 The Voyager spacecraft Launched on September 5, 1977, flew past Jupiter (March 5, 1979) and Saturn (November 12, 1980). It is now one of four probes, including Pioneer 10, Pioneer 11, and Voyager 2, that are heading out of the Solar System. Voyager 1 became the most remote human-made object when, in mid-1998, it surpassed the heliocentric distance of Pioneer 10. In Febraury 2003, Voyager 1 was 83.6 astronomical units (12.54 billion km, 7.79 billion miles) from the Sun, equivalent to a round-trip light-travel time of just over 23 hours 18 minutes. It is traveling at a speed of 17.23 km per second (38,551 miles per hour) away from the Sun in the general direction of the Solar Apex (the direction of the Sun's motion relative to nearby stars), so that it will probably be the first of the four present star-bound craft to reach the terminal shock and cross the heliopause into true interstellar space. Thereafter, it will have a journey lasting almost 40,000 years before it passes the M4 dwarf AC +79° 3888 at the remote distance of 1.64 light-years (0.50 parsec). Together with its sister craft, Voyager 1 is currently engaged on the Voyager Interstellar Mission.
