Members of the Voyager flight team celebrate after receiving the first coherent data from Voyager 1 in five months at NASA's Jet Propulsion Laboratory on April 20. - NASA/JPL-Caltech.
It takes 22 1/2 hours to send a signal to Voyager 1, more than 15 billion miles (24 billion kilometers) away in interstellar space. The signal travel time is double that for a round trip. Contact was never lost, rather it was like making a phone call where you can’t hear the person on the other end, a JPL spokeswoman said Tuesday.
The spacecraft launched in 1977 and is now 15 billion miles from Earth. It went silent in November. Scientists at JPL figured out how to get it talking again.
NASA and Voyager 1 resumed communications and operations after a fault protection system switched the interstellar spacecraft's mode of communication to one using less power.
NASA's Voyager 1 spacecraft is depicted in this artist's concept traveling through interstellar space, or the space between stars, which it entered in 2012. - NASA/JPL-Caltech.
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 .
On September 12, 2013, NASA announced that Voyager 1 had left the heliosheath and entered interstellar space, [33] although it still remains within the Sun's gravitational sphere of influence. Of the eleven instruments carried on Voyager 1, four are still operational and continue to send back data. It is expected that at least one science ...
The Voyager 1 spacecraft is functioning normally again after the aging probe’s dwindling power supply triggered a communications blackout. ... Voyager mission manager at NASA’s Jet Propulsion ...
