So they have been operating for more than 47 years.<\/p>\n<p>NASA officials have reported several difficulties with the spacecraft in recent years, mainly communication issues. The most recent problems involved the Voyager 1 spacecraft. NASA <a class=\"wsw__a\" href=\"https:\/\/www.jpl.nasa.gov\/news\/nasas-voyager-1-resumes-sending-engineering-updates-to-earth\/\">said<\/a> in a statement in April it had remained out of touch with the spacecraft for the previous five months.<\/p>\n<p>Agency officials said they later learned the problem was linked to a <strong>chip<\/strong> inside one of Voyager 1\u2019s onboard computers. The issue made data being sent by the spacecraft unreadable. NASA said its engineers were able to fix that problem by making changes to how the spacecraft stores and reads data.<\/p>\n<p>Then, in October, NASA <a class=\"wsw__a\" href=\"https:\/\/blogs.nasa.gov\/voyager\/2024\/10\/28\/after-pause-nasas-voyager-1-communicating-with-mission-team\/\">reported<\/a> another communication issue that resulted in a brief delay in receiving data from Voyager 1. That problem turned out to be linked to the spacecraft\u2019s radio transmitter system.<\/p>\n<div class=\"wsw__embed\">\n<figure class=\"media-image js-media-expand\">\n<div class=\"img-wrap\">\n<div class=\"thumb\">\n<img decoding=\"async\" alt=\"This archival image taken at NASA\u2019s Jet Propulsion Laboratory on March 23, 1977, shows engineers preparing the Voyager 2 spacecraft ahead of its launch later that year.

This activation \u2013 meant to save power \u2013 led Voyager 1 to start sending signals to a different radio <strong>transmitter<\/strong> system than it normally uses.<\/p>\n<p>This meant NASA had to listen for the signals on the S-band instead of the usual X-band. Once they did this, they were able to start receiving data again. NASA has said the S-band is much weaker than the X-band, so engineers were seeking to get the X-band radio communication system back online for long-term use.<\/p>\n<p>NASA said the agency had not used the S-band since 1981.<\/p>\n<p>Voyager 1 and Voyager 2 are NASA\u2019s most distant operating spacecraft. The agency has reported Voyager 1 is exploring space from about 24 billion kilometers from Earth, while Voyager 2 is operating from about 20.5 billion kilometers away.<\/p>\n<div class=\"wsw__embed\">\n<figure class=\"media-image js-media-expand\">\n<div class=\"img-wrap\">\n<div class=\"thumb\">\n<img decoding=\"async\" alt=\"This artist's illustration shows NASA's Voyager spacecraft.

Both spacecraft successfully carried out studies of those planets. Later, Voyager 2 made the first-ever close observations of Uranus and Neptune in 1989.<\/p>\n<p>The two spacecraft then began a new mission to explore distant areas of space. In 2013, NASA announced Voyager 1 had crossed over the border dividing our solar system from interstellar space. The term \u201cinterstellar\u201d means \u201cbetween stars.\u201d Scientists say interstellar space begins where the sun&#8217;s continuous flow of particles and its magnetic field stop.<\/p>\n<p>Voyager 2 first entered interstellar space in 2018. NASA said the spacecraft was more than 17.7 billion kilometers from the sun at the time. Both Voyagers are the only spacecraft so far to explore interstellar space.<\/p>\n<p>The space agency says the Voyagers are studying how the interstellar medium interacts with the solar wind. Solar wind is the continuous flow of charged particles released by the sun. The spacecraft have also provided data on the heliosphere, a kind of protective <strong>bubble<\/strong> around our solar system.<\/p>\n<p>Suzanne Dodd is the current project manager for the Voyager mission at NASA\u2019s Jet Propulsion Laboratory in California. She recently <a class=\"wsw__a\" href=\"https:\/\/science.nasa.gov\/missions\/voyager-program\/still-kickin-since-the-70s-nasas-voyager-mission-keeps-exploring\/\">said<\/a> in a statement the agency has no plans to retire the two Voyagers as long as they are communicating with mission members back on Earth. Dodd said the spacecraft are currently centered on observing how interstellar space and the heliosphere interact with each other.<\/p>\n<div class=\"wsw__embed\">\n<figure class=\"media-image js-media-expand\">\n<div class=\"img-wrap\">\n<div class=\"thumb\">\n<img decoding=\"async\" alt=\"In this Aug. 4, 1977, photo provided by NASA, the 'Sounds of Earth' record is mounted on the Voyager 2 spacecraft in the Safe-1 Building at the Kennedy Space Center, Fla.
