Voyager 2 is a space probe launched by NASA on August 20, 1977, as a part of the Voyager program. It was launched on a trajectory towards the gas giants ( Jupiter and Saturn ) and enabled further encounters with the ice giants ( Uranus and Neptune ).
NASA sent a radio signal to Voyager 2, located billions of miles away in interstellar space, and restored communications with the spacecraft after an errant command caused a blackout.
Several space probes and the upper stages of their launch vehicles are leaving the Solar System, all of which were launched by NASA. 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.
Voyager 2 trails its twin in interstellar space at more than 12 billion miles (19 billion kilometers) from Earth. At that distance, it takes more than 18 hours for a signal to travel one way.
But the data being sent by Voyager 2 is not reaching that network. Voyager 2 is now floating on its own, almost 20 billion kilometres from Earth. Nasa still hopes to be able to re-establish ...
It left the heliosphere and crossed into interstellar space in December 2018. As with Voyager 1, scientists are now using Voyager 2 to learn what the Solar System is like beyond the heliosphere. Launched: 20 August 1977; Destination: Jupiter, Saturn, Uranus, Neptune; Arrival: 9 July 1979; Institution: NASA; Primary mission completion: August 1989
Mission engineers sent a command to shutter the Voyager 2’s Plasma Science, or PLS, experiment — which was used to observe solar winds — on September 26 using the Deep Space Network, a ...
The Voyager program is an American scientific program that employs two interstellar probes, Voyager 1 and Voyager 2. They were launched in 1977 to take advantage of a favorable planetary alignment to explore the two gas giants Jupiter and Saturn and potentially also the ice giants, Uranus and Neptune - to fly near them while collecting data for ...
