Two years later, Voyager 1 began experiencing a third "tsunami wave" of coronal mass ejections from the Sun that continued to at least December 15, 2014, further confirming that the probe is indeed in interstellar space. Voyager 1 crossed the heliopause and entered interstellar space on August 25, 2012, making it the first spacecraft to do so. Voyager 1 studied the weather, magnetic fields, and rings of the two gas giants and was the first probe to provide detailed images of their moons.Īs part of the Voyager program and like its sister craft Voyager 2, the spacecraft's extended mission is to locate and study the regions and boundaries of the outer heliosphere and to begin exploring the interstellar medium. NASA had a choice of either doing a Pluto or Titan flyby exploration of the moon took priority because it was known to have a substantial atmosphere. The probe made flybys of Jupiter, Saturn, and Saturn's largest moon, Titan. At a distance of 161 AU (24 billion km 15 billion mi) from Earth as of August 2023, it is the most distant human-made object from Earth. Real-time distance and velocity data is provided by NASA and JPL. It communicates through NASA's Deep Space Network to receive routine commands and to transmit data to Earth. Launched 16 days after its twin Voyager 2, Voyager 1 has been operating for 45 years, 11 months and 27 days as of SeptemUTC. Voyager 1 is a space probe launched by NASA on September 5, 1977, as part of the Voyager program to study the outer Solar System and interstellar space beyond the Sun's heliosphere. In the SVG file, hover over a trajectory or orbit to highlight it and its associated launches and flybys. Plots 2 to 4 are third-angle projections at 20% scale. Plot 1 is viewed from the north ecliptic pole, to scale. Markers denote positions on 1 January of each year, with every fifth year labelled. Heliocentric positions of the five interstellar probes (squares) and other bodies (circles) until 2020, with launch and flyby dates.
