NASA Demonstrates X-ray Navigation in Space

NICER's mirror assemblies concentrate X-rays onto silicon detectors to gather data that probes the interior makeup of neutron stars, including those that appear to flash regularly, called pulsars. (NASA's Goddard Space Flight Center/Keith Gendreau)

In a technology first, NASA demonstrated fully autonomous X-ray navigation in space. This technology could work in concert with existing spacecraft-based radio and optical systems.

Such a system provides a new option for spacecraft to autonomously determine their locations outside the currently used Earth-based global navigation networks such as the Global Positioning System (GPS).
