NASA Reconnects with Voyager, Longest Serving Mission in History
The most recent problems involved the Voyager 1 spacecraft.

NASA said in a statement in April it had remained out of touch with the spacecraft for the previous five months.

Agency officials said they later learned the problem was linked to a chip inside one of Voyager 1’s onboard computers.

The issue made data being sent by the spacecraft unreadable.
- Public domaingeneral-american
NASA Reconnects with Voyager, Longest Serving Mission in History
NASA said its engineers were able to fix that problem by making changes to how the spacecraft stores and reads data.

Then, in October, NASA reported another communication issue that resulted in a brief delay in receiving data from Voyager 1.

That problem turned out to be linked to the spacecraft’s radio transmitter system.

The agency said that, for some reason, Voyager 1’s fault protection system was activated when NASA sent a command for the spacecraft to turn on one of

its heaters. This activation meant to save power led Voyager 1 to start sending signals to a different radio transmitter system than it normally uses.

This meant NASA had to listen for the signals on the S-band instead of the usual X-band. Once they did this, they were able to start receiving data again.
- Public domaingeneral-american
NASA Reconnects with Voyager, Longest Serving Mission in History
NASA has said the S-band is much weaker than the X-band, so engineers were seeking to get the X-band radio communication system back online for long-term

use. NASA said the agency had not used the S-band since 1981.

Voyager 1 and Voyager 2 are NASA’s most distant operating spacecraft.
- Public domaingeneral-american
NASA Reconnects with Voyager, Longest Serving Mission in History
The agency has reported Voyager 1 is exploring space from about 24 billion kilometers from Earth, while Voyager 2 is operating from about

NASA Reconnects with Voyager, Longest Serving Mission in History
20.5 billion kilometers away.
- Public domaingeneral-american
NASA Reconnects with Voyager, Longest Serving Mission in History
Because of this great distance, NASA says its communication with the two Voyagers takes about one day to receive data, and another day to send information back from Earth.
- Public domaingeneral-american
NASA Reconnects with Voyager, Longest Serving Mission in History
The two Voyagers were first designed to explore Jupiter and Saturn. Both spacecraft successfully carried out studies of those planets.
- Public domaingeneral-american

Later, Voyager 2 made the first-ever close observations of Uranus and Neptune in 1989.
- Public domaingeneral-american

The two spacecraft then began a new mission to explore distant areas of space.
- Public domaingeneral-american

In 2013, NASA announced Voyager 1 had crossed over the border dividing our solar system from interstellar space.
- Public domaingeneral-american

The term “interstellar” means “between stars.”
- Public domaingeneral-american

Scientists say interstellar space begins where the sun's continuous flow of particles and its magnetic field stop.
- Public domaingeneral-american
NASA Reconnects with Voyager, Longest Serving Mission in History
Voyager 2 first entered interstellar space in 2018.
- Public domaingeneral-american
NASA Reconnects with Voyager, Longest Serving Mission in History
NASA said the spacecraft was more than 17.7 billion kilometers from the sun at the time.

Both Voyagers are the only spacecraft so far to explore interstellar space.
