NASA Revives Voyager Thrusters ‘Considered Dead’ for 20 Years

NASA’s Voyager 1 spacecraft has been in space for nearly 50 years, enduring the harsh environment of outer space while teams on the ground figure out ways to keep its aging hardware from falling apart. In the latest attempt to keep Voyager alive, engineers managed to bring the spacecraft’s old thrusters back to life after being inoperable for decades. NASA’s engineers revived a set of thrusters on board the Voyager 1 spacecraft to use as backup while the mission goes offline for ongoing upgrades to a radio antenna used to communicate with deep space missions, the space agency revealed this week. Voyager’s primary roll thrusters had stopped working in 2004 after losing power in two small internal heaters, but the team managed to restart the thrusters while the spacecraft cruises through interstellar space at a distance of 15.14 billion miles away (24.4 billion kilometers). Voyager 1 launched in 1977, less than a month after its twin probe, Voyager 2, began its journey to space. The tw ... Read full article.
