NASA builds unusual testbed for analyzing X-ray navigation technologies

Pulsars have a number of unusual qualities. Like zombies, they shine even though they're technically dead, and they rotate rapidly, emitting powerful and regular beams of radiation that are seen as flashes of light, blinking on and off at intervals from seconds to milliseconds. A NASA team has built a first-of-a-kind testbed that simulates these distinctive pulsations.
