The Voyager 1 is a 722 kilogram space probe launched by NASA on September 5, 1977, to study the outer Solar System. Operating for 36 years, 10 months and 28 days as of August 2, 2014, the spacecraft communicates with the Deep Space Network to receive routine commands and return data. At a distance of about 127.63 AU (1.909×1010 km) from the Earth as of June 27, 2014, it is the farthest spacecraft from Earth
On September 12, 2013, NASA announced that Voyager 1 had crossed the heliopause and entered interstellar space on August 25, 2012, making it the first spacecraft to do so. As of 2013, the probe was moving with a relative velocity to the Sun of about 17 km/s. With the velocity the probe is currently maintaining, Voyager 1 is traveling at about 520 million kilometers per year (325 million miles per year). On July 7, 2014, NASA reported Voyager 1 experienced a new third "tsunami wave", generated from activity (coronal mass ejections) on the sun, further confirming that the probe is in interstellar space. Voyager 1 is expected to continue its mission until 2025, when its generators will no longer supply enough power to operate any of its instruments.
