Beta Probe

Background
Beta Probe is a generic UNSC term referring to one of the Slipspace Probes used by Remote Scanning Outposts. It sent out radio pings and analyzed the spectrum from radio to X rays. The Beta Probe is designed to be able to survive the transition from slipspace to normal space in order to collect data.

Appearances
The Beta Probe of the Archimedes, directly above Sigma Octanus IV, reported the same findings as Alpha Probe. Both probes gave the mysterious object mass at 20,000 tons. The mysterious object was a Covenant Ship.
