said Bruce Waggoner, the Voyager mission assurance manager. The heat can help reverse the radiation damage, which degrades the performance of the spacecraft\u2019s components, he said.\n    <\/p>\n<p class=\"paragraph inline-placeholder vossi-paragraph\" data-uri=\"cms.cnn.com\/_components\/paragraph\/instances\/cm2yrunpf000y356mr4o5on4o@published\" data-editable=\"text\" data-component-name=\"paragraph\" data-article-gutter=\"true\">\n            Messages are relayed to Voyager from mission control at NASA\u2019s Jet Propulsion Laboratory in Pasadena, California, through the agency\u2019s Deep Space Network.

If the spacecraft draws more power than it should, the fault protection system automatically shuts off systems that aren\u2019t essential to conserve power.\n    <\/p>\n<p class=\"paragraph inline-placeholder vossi-paragraph\" data-uri=\"cms.cnn.com\/_components\/paragraph\/instances\/cm2yrunpf0011356me6an18n5@published\" data-editable=\"text\" data-component-name=\"paragraph\" data-article-gutter=\"true\">\n            The team discovered the latest issue when it couldn\u2019t detect the spacecraft\u2019s response signal through the Deep Space Network on October 18.\n    <\/p>\n<p class=\"paragraph inline-placeholder vossi-paragraph\" data-uri=\"cms.cnn.com\/_components\/paragraph\/instances\/cm2yrunpf0012356malhu0fos@published\" data-editable=\"text\" data-component-name=\"paragraph\" data-article-gutter=\"true\">\n            Voyager 1 has been using one of its two radio transmitters, called an X-band<strong> <\/strong>based on the frequency it utilizes, for decades. Meanwhile, the other transmitter, called the S-band, which uses a different frequency, hasn\u2019t been employed since 1981 because its signal is much fainter than the X-band\u2019s.\n    <\/p>\n<p class=\"paragraph inline-placeholder vossi-paragraph\" data-uri=\"cms.cnn.com\/_components\/paragraph\/instances\/cm2yrunpf0013356m4xjeld9i@published\" data-editable=\"text\" data-component-name=\"paragraph\" data-article-gutter=\"true\">\n            Engineers suspect the fault protection system lowered the rate at which data was being sent back from the transmitter, which changed the nature of the signal shared by Voyager 1 to the Deep Space Network monitors. The Voyager 1 team ultimately located the probe\u2019s response later on October 18 by sifting through signals the Deep Space Network was receiving.\n    <\/p>\n<p class=\"paragraph inline-placeholder vossi-paragraph\" data-uri=\"cms.cnn.com\/_components\/paragraph\/instances\/cm2yrunpf0014356me3ukzeei@published\" data-editable=\"text\" data-component-name=\"paragraph\" data-article-gutter=\"true\">\n            But on October 19, communication with Voyager 1 appeared to stop completely.\n    <\/p>\n<p class=\"paragraph inline-placeholder vossi-paragraph\" data-uri=\"cms.cnn.com\/_components\/paragraph\/instances\/cm2yrunpf0015356moful9l88@published\" data-editable=\"text\" data-component-name=\"paragraph\" data-article-gutter=\"true\">\n            The team believes the fault protection system was additionally triggered two more times, which may have switched off the X-band transmitter and shifted the spacecraft to the S-band transmitter that uses less power, NASA said.\n    <\/p>\n<p class=\"paragraph inline-placeholder vossi-paragraph\" data-uri=\"cms.cnn.com\/_components\/paragraph\/instances\/cm2yrunpf0016356m1e5wau9n@published\" data-editable=\"text\" data-component-name=\"paragraph\" data-article-gutter=\"true\">\n            While Voyager 1\u2019s team wasn\u2019t sure that the faint S-band signal would be detectable due to the spacecraft\u2019s distance from Earth, Deep Space Network engineers located it.\n    <\/p>\n<p class=\"paragraph inline-placeholder vossi-paragraph\" data-uri=\"cms.cnn.com\/_components\/paragraph\/instances\/cm2yrunpf0017356m5n1vt4zu@published\" data-editable=\"text\" data-component-name=\"paragraph\" data-article-gutter=\"true\">\n            The team won\u2019t send commands to Voyager 1 to turn on the X-band transmitter again until it deduces what triggered the fault protection system, which could take weeks.
