Three of the probes, Voyager 1, Voyager 2, and New Horizons, are still functioning and are regularly contacted by radio communication, while Pioneer 10 and Pioneer 11 are now derelict. In addition to these spacecraft, some upper stages and de-spin weights are leaving the Solar System, assuming they continue on their trajectories.
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 .
Voyager 1 and Pioneer 10 are the most widely separated human-made objects anywhere since they are travelling in roughly opposite directions from the Solar System. In December 2004, Voyager 1 crossed the termination shock, where the solar wind is slowed to subsonic speed, and entered the heliosheath, where the solar wind is compressed and made ...
An enduring mystique surrounds the Voyager 1 and 2 probes. Launched two weeks apart in 1977, the twin probes changed the way we see our solar system, sending back stunningly detailed views of ...
Voyager 1 and its twin send back science data continuously through the Deep Space Network, a system of radio antennae on Earth, with about six to eight hours of the probes’ detections returning ...
In 2012, Voyager 1 ventured beyond the solar system, becoming the first human-made object to enter interstellar space, or the space between stars. Voyager 2 followed suit in 2018.
Voyager 1 was the first space probe to provide detailed images of the two largest planets and their major moons. The Voyager 1 spacecraft. The spacecraft, still traveling at 64,000 km/h (40,000 mph), is the most distant human-made object from Earth and the first one to leave the Solar System. [5]
As Voyager 1 and its twin probe, Voyager 2, have aged, the mission team has slowly turned off nonessential systems on both spacecraft to conserve power, including heaters.
