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 the interstellar space beyond the Sun's heliosphere. It was launched 16 days after its twin, Voyager 2 .
The farthest spacecraft from Earth, Voyager 1 is currently exploring uncharted territory about 15.4 billion miles (24.9 billion kilometers) away. ... “The bigger issue is how long can we keep ...
Given Voyager 1’s immense distance from Earth, it takes a radio signal about 22.5 hours to reach the probe, and another 22.5 hours for a response signal from the spacecraft to reach Earth.
Voyager 1 was launched after Voyager 2, but along a shorter and faster trajectory that was designed to provide an optimal flyby of Saturn's moon Titan, [21] which was known to be quite large and to possess a dense atmosphere. This encounter sent Voyager 1 out of the plane of the ecliptic, ending its planetary science mission. [22]
As of November 2017 it has a distance from the Sun of about 140 astronomical units (AU) [14] (21 billion kilometers, or 0.002 light years), and it will not be overtaken by any other current craft. In August 2012, Voyager 1 became the first human-built spacecraft to enter interstellar space. Though declining, the onboard power source should keep ...
The Voyager 1 spacecraft is sending back a steady stream of scientific data from uncharted territory for the first time since a computer glitch sidelined the historic NASA mission seven months ago.
NASA’s 46-year-old Voyager 1 spacecraft has experienced a computer glitch that prevents it from returning science data to Earth from the solar system’s outer reaches.
Voyager 1 entered interstellar space in 2012. [28] As of January 19, 2019, Voyager 1 was at a distance of 145.148 AU (13.492 billion miles (21.713 × 10 ^ 9 km)) from Earth, traveling away from the Sun at a speed of about 10.6 mi/s (17.1 km/s), which corresponds to a greater specific orbital energy than any other probe.
