Covenant spy probe

A spy probe depicted in the comic book adaptation of Halo: The Fall of Reach.

Covenant spy probes are small, softball or baseball-sized automaton machines used by the Covenant for reconnaissance and intelligence roles.

Overview

These machines have a single photo eye for data collection. Over a number of days, it slowly builds up a charge as it collects data and information. Once it reaches critical energy, a tiny sliver of thallium nitride memory crystal is ejected at the speed of light, surrounded by a miniature slipspace field. The sliver is directed toward precise Slipspace coordinates where a waiting Covenant entity will recover it and the data it contains.

During the Human-Covenant War probes were colored dark gray so they can blend into the hull of UNSC vessels, instead of the standard lavender color of Covenant alloys.

Operational use

An example use of the probe was at the Battle of Sigma Octanus IV where a probe attached to the UNSC Iroquois and revealed the human presence at Reach. This culminated in the Fall of Reach.

Trivia

The spy probe is similar in function to the UNSC's telemetry probe.
