Voyager 1, which is currently more than 15 billion miles (24 billion kilometers) from Earth, is the most distant human-made object in the universe.

While the spacecraft should have had ample power to execute this command, the prompt instead triggered Voyager 1&#8217;s fault protection system.<\/p>\n<p>Two days later, when NASA engineers looked for Voyager 1&#8217;s response with the Deep Space Network \u2014 a worldwide network of radio antennae used to support interplanetary missions \u2014 they could not detect the spacecraft&#8217;s signal. The team eventually found Voyager 1&#8217;s signal later that day. However, the next day (Oct. 19), communication with Voyager &#8220;appeared to stop entirely,&#8221; according to NASA.<\/p>\n<p><strong>Related: <\/strong><a data-analytics-id=\"inline-link\" href=\"https:\/\/www.livescience.com\/space\/space-exploration\/nasa-shuts-off-voyager-2-science-instrument-as-power-dwindles\" data-before-rewrite-localise=\"https:\/\/www.livescience.com\/space\/space-exploration\/nasa-shuts-off-voyager-2-science-instrument-as-power-dwindles\"><u><strong>NASA shuts off Voyager 2 science instrument as power dwindles<\/strong><\/u><\/a><\/p>\n<div id=\"slice-container-newsletterForm-articleInbodyContent-qcV7xDCTZGQULrbZYvtMxM\" class=\"slice-container newsletter-inbodyContent-slice newsletterForm-articleInbodyContent-qcV7xDCTZGQULrbZYvtMxM slice-container-newsletterForm\">\n<div data-hydrate=\"true\" class=\"newsletter-form__wrapper newsletter-form__wrapper--inbodyContent\">\n<div class=\"newsletter-form__container\">\n<section class=\"newsletter-form__top-bar\"\/>\n<section class=\"newsletter-form__main-section\">\n<p class=\"newsletter-form__strapline\">Get the world\u2019s most fascinating discoveries delivered straight to your inbox.<\/p>\n<\/section>\n<\/div>\n<\/div>\n<\/div>\n<p>Engineers suspect that, during this period, Voyager 1&#8217;s fault protection system triggered two more times. This forced the spacecraft to turn off its main X-band radio transmitter and switch to its backup S-band transmitter, which uses a different frequency and is &#8220;significantly fainter&#8221; than the main transmitter, according to NASA.<\/p>\n<p>&#8220;While the S-band uses less power, Voyager 1 had not used it to communicate with Earth since 1981,&#8221; the agency added.<\/p>\n<p>On Oct. 22, engineers sent a command to confirm that the spacecraft was indeed using its backup S-band transmitter.
