Voyager's Low-Energy Charged Particle Instrument

This animation shows the viewing directions of the Low-Energy Charged Particle (LECP) instrument on NASA's Voyager 1 and 2 spacecraft. The stepper motor moves the detector platform 45 degrees every 192 seconds and has been doing so since the launch of both Voyager spacecraft in 1977. Designed four decades ago at the Johns Hopkins University Applied Physics Laboratory in Laurel, Md., the device has accumulated more than 6 million steps, even though it was expected to last for only 500,000 steps.
