Alpha Probe

Alpha Probe is a generic UNSC term referring to one of the Slipstream Space probes used by Remote Scanning Outposts. It sends out radio pings and analyzes the spectrum from radio to X-ray. The Alpha Probe, like all probes used by the RSOs, is designed to be able to survive the transition from slipspace to normal space in order to collect data.

Appearances
