NASA has confirmed that Voyager 1, the interstellar spacecraft, has successfully reconnected with NASA after a temporary halt in communications in late October. The spacecraft unexpectedly switched off its primary radio transmitter, known as the X-band, before turning on its much weaker S-band transmitter. This unprecedented move left the Voyager mission team unable to download scientific data and information about the spacecraft’s status. The Voyager 1 is currently positioned approximately 15.4 billion miles away from Earth, with the S-band not having been utilized for over four decades. The recent activation of the X-band transmitter has enabled the resumption of data collection from the four operational science instruments onboard the spacecraft.
## Reactivation of Voyager 1’s Communication
Earlier this month, NASA engineers were successful in reactivating the X-band transmitter, paving the way for the collection of crucial data from Voyager 1. With communications now restored, the team is focused on completing the remaining tasks to return the spacecraft to its pre-issue state. One of the essential tasks involves resetting the system that synchronizes the three onboard computers of Voyager 1.
## Activation of S-Band by Fault Protection System
The activation of the S-band transmitter was triggered by the spacecraft’s fault protection system when engineers initiated a heater on Voyager 1. The system determined that the probe lacked sufficient power, leading to the automatic shutdown of non-critical systems to ensure the operation of vital components. Despite the activation of the S-band, Voyager 1 had not utilized this communication method since 1981.
## Voyager 1’s Historic Journey
Voyager 1 embarked on its extraordinary journey in 1977 alongside its twin, Voyager 2, exploring the gas giant planets of the solar system. Providing remarkable views of Jupiter’s red spot and Saturn’s iconic rings, Voyager 1 utilized Saturn’s gravitational pull to propel itself past Pluto. Currently, four of the ten scientific instruments onboard Voyager 1 are actively studying particles, plasma, and magnetic fields in interstellar space.
