Each of NASA’s Voyager probes are equipped with three radioisotope thermoelectric generators (RTGs), including the one shown here at NASA’s Kennedy Space Center in Florida. The RTGs provide power for the spacecraft by converting the heat generated by the decay of plutonium-238 into electricity. Launched in 1977, the Voyager mission is managed for NASA by … Read more
Both Voyager probes feature three sets, or branches, of thrusters: two sets of attitude propulsion thrusters and one set of trajectory correction maneuver thrusters. During the mission’s planetary flybys, both types of thrusters were used for different purposes. But as Voyager 1 travels on an unchanging path out of the solar system, its thruster needs … Read more
5 min read NASA’s Perseverance Fords an Ancient River to Reach Science Target Originally thought of as little more than a route clear of rover-slowing boulders, Neretva Vallis has provided a bounty of geologic options for the science team. After detouring through a dune field to avoid wheel-rattling boulders, NASA’s Perseverance Mars rover reached … Read more
Known for his steady leadership, consensus building, and enthusiasm for engaging the public in science, Stone left a deep impact on the space community. Edward C. Stone, former director of NASA’s Jet Propulsion Laboratory in Southern California, and longtime project scientist of the agency’s Voyager mission, died on June 9, 2024. He was 88. He … Read more
The efforts should help extend the lifetimes of the agency’s interstellar explorers. Engineers for NASA’s Voyager mission are taking steps to help make sure both spacecraft, launched in 1977, continue to explore interstellar space for years to come. One effort addresses fuel residue that seems to be accumulating inside narrow tubes in some of the … Read more
