Voyager 1 just fired up some thrusters for the first time in 37 years
When Voyager 1's trajectory correction maneuver thrusters last fired, Ronald Reagan had just been elected president. Over 30 years ago, about a decade into the spacecraft's journey out to the edge of our solar system and beyonde thrusters had officially served their purpose. The trajectory correction maneuver (TCM) thrusters sent out little puffs of power to correct the object's course, allowing Voyager 1 to explore Jupiter, Saturn, and several moons orbiting them. After the last course correction for Saturn on November 8, 1980, the TCMs went silent. Last week, NASA scientists fired them up again. And 37 years after being put out to pasture, the thrusters worked. They could even extend the mission of the invaluable space probe by several years. Voyager 1 is an important vessel. It's the fastest spacecraft we've got, traveling at around 11 miles per second. It's also the farthest. Its twin, Voyager 2, is nearly 11 billion miles away from the Sun, pushing th...
