After a brief pause in Voyager 1 communications, NASA re -established a connection with the interstellar spacecraft located more than 15 billion kilometers from Earth, using an unused frequency more than forty years.
Sometimes the communication between NASA and Voyager 1 has been stained. In fact, the spacecraft stopped sending readable data to the Jet of NASA propulsion laboratory in southern California on November 14, 2023, and it was not until April that mission drivers began receiving orders again.
More recently, the spacecraft disabled one of its two transmitters after what the engineers suspected was due to the Voyager 1 failure protection system, which responds autonomously to the troubles of board.
For example, if the spacecraft uses too much power from its source of supply, the protection of failures will begin to preserve the energy by deactivating non -essential systems, NASA explained.

The space agency said that the flight team sent a command to activate one of the heaters of the spacecraft on October 16. The command takes almost 23 hours to travel from Earth to the spacecraft, and then another 23 hours for the data to travel again.
The engineers suspected that Voyager 1 should have had a lot of power to operate the Bruc, although the failure protection system was triggered.
On October 18, the team learned of the problem, because the deep space network could not detect the Voyager 1 signal. The communication between NASA and the spacecraft occurs at the X -band radio transmitter, called the frequency it uses.

The fault protection system reduced the speed that the transmitter could send the data again to NASA, determined the engineers, therefore changing the X signal the deep space network needed to listen.
Once the signal was located, Voyager 1 seemed to be in a stable state and the team began investigating what happened.
But on October 19, the communication between the team and Voyager 1 stopped again, this time completely.
The team believed that the Voyager 1 failure protection system was twice more triggered and changed to a second radio transmitter called S-Band, which uses less power.

Voyager 1 had not used the S band to communicate with the land since 1981.
The engineers with the deep space network were able to detect the communication of the spacecraft from the S. S. instead of the risk of re -igniting the X band before discovering what caused the failure protection system to be triggered, the team sent an order on October 22 to confirm that the band’s transmitter was working.
The team is now working to collect information to help them find out what happened so that Voyager 1 can return to normal operations.

Voyager 1 Odyssey began in 1977 when the spacecraft and its twin, Voyager 2, launched themselves on a tour of the giant planets of the solar system gas.
After receiving the views to the dazzling postcard of the giant red spot of Jupiter and the bright rings of Saturn, Voyager 2 put in Uranus and Neptune. In the meantime, Voyager 1 used Saturn as gravitational slings to feed -above Pluto.
