How would you explain to an 8th grader, who knows just the basics of physics, the working and the purpose of NASA's Voyager 1 and Voyager 2?
That sounds interesting! How do they move in space?
They move using thrusters powered by radioisotope thermoelectric generators, which convert the decay of radioactive material into electricity. This allows them to continue operating even far from the sun, where solar power is inadequate.
