Called the flight data system (FDS), it can no longer communicate properly with another subsystem called the telemetry modulation unit (TMU). This results in the inability for Voyager 1 to send any science or engineering data back to Earth.<\/p>\n<p class=\"wp-block-paragraph\">However, Voyager 1 can and still is, receiving and executing commands from Earth. A very good sign as without that ability, Voyager 1 would have a much higher chance of being loss.<\/p>\n<p class=\"wp-block-paragraph\">In a normal scenario, data from the FDS would be gathered from the various sensors and instruments on the spacecraft, packaged up into a bundle of ones and zeros, and then sent back to Earth via the TMU. In the current scenario, the ones and zeros are stuck in a repeating pattern, unusable to engineers and scientists on the ground.<\/p>\n<p>\t<span class=\"outbrain-ad-label\"><\/span><\/p>\n<p>\t\t<script type=\"text\/plain\">\n\t\t\twindow.adSlotsConfig = window.adSlotsConfig || [];<\/p>\n<p>\t\t\tadSlotsConfig.push( {\n\t\t\t\tslotID: '\/1049447\/Outbrain',\n\t\t\t\tslotName: 'div-gpt-ad-outbrain-ad-39502',\n\t\t\t\tsizes: [300, 250],\n\t\t\t\tslotPosition: 'mid_article'\n\t\t\t} );\n\t\t<\/script><\/p>\n<p class=\"wp-block-paragraph\">These \u201cpackages\u201d of ones and zeros, called binary, is the basic communication method for all computers. In a world less worried about efficiency, data could be transmitted using much easier to understand to humans formats like XML or JSON (the only way I can easily explain what these are is like imagine a really nerdy and techy version of a forum with nesting items, but for data storage).<\/p>\n<p class=\"wp-block-paragraph\">However, when interoperability and efficiency is key, to binary we go. <em>On a personal note, I remember having to parse binary by hand for a project using ADSB transceivers when I was a software engineer.

Launched in 1977, many of the documents written by the original engineers are decades old and were written with the idea that the spacecraft wouldn\u2019t last longer than its five year lifespan. So NASA isn\u2019t optimistic on having a fix in the short-term. Rather it could take weeks to come up with a new solution.<\/p>\n<p class=\"wp-block-paragraph\">Join our Discord Server: Join the community with forums and chatrooms about space!<\/p>\n<h2 class=\"wp-block-heading\" id=\"h-how-much-longer-can-the-voyager-probes-live\">How much longer can the Voyager probes live?<\/h2>\n<p class=\"wp-block-paragraph\">Launched along side its twin, Voyager 2, Voyager 1\u2019s mission was to fly by the outer planets of Jupiter Saturn, Uranus, and Neptune. After completing that goal, NASA sent the probes on a new mission to explore the outer most regions of the solar system.<\/p>\n<p class=\"wp-block-paragraph\">Currently Voyager 1 is over 15 billion miles away from Earth and Voyager 2 is more than 12 billion miles. Both probes passed the Heliopause, the boundary between the outer reaches of our solar winds and interstellar space. This means the data Voyager 1 and 2 are sending back to Earth is unmatched to any other mission at the moment for heliophysic research.<\/p>\n<p class=\"wp-block-paragraph\">The age and distance of the two Voyager probes bring troubles to their continued operation. For starters, its takes almost a day (22.5 hours) to reach Voyager 1 with a high power radio burst encoded with new commands. Likewise, it takes Voyager 1 a day for its telemetry to reach Earth. Meaning a round trip troubleshoot of any problem takes two days. And that\u2019s just to know if what you told it to do worked.<\/p>\n<p class=\"wp-block-paragraph\">In order for the probes to last as long as they have, NASA has had to shutdown certain instruments to conserve power. Powered by three radioisotope thermoelectric generators each, a generator powered by the decay of radioactive material, the spacecraft could have power for as long as into the 2030s.<\/p>\n<p><ins data-ad-format=\"auto\" class=\"adsbygoogle adsbygoogle-noablate\" data-ad-client=\"ca-pub-7125080057269629\" data-adsbygoogle-status=\"done\" style=\"display: block; margin: auto; background-color: transparent; height: 280px;\"><\/ins><\/p>\n<p class=\"wp-block-paragraph\">NASA has shutdown any instrument that isn\u2019t useful when studying interstellar space like cameras and spectrometers. This conserves power both in their operations but keeping them at optimal temperatures using heaters.<\/p>\n<p class=\"wp-block-paragraph\">Eventually NASA will have to be more picky on what instruments it keeps operating as power levels dwindle. But for now, they are just worried about getting its science data back online.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Voyager 1 sending nothing but garbage Voyager 1 has experienced a computer glitch on one of the spacecraft\u2019s three onboard computers.
