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

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

Overview[edit]

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 miniatureslipspace field. The sliver is directed toward precise Slipspace coordinates where a waiting Covenant entity will recover it and the data it contains.^[1]

During theHuman-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.^[1]

Operational use[edit]

An example use of the probe was at theBattle of Sigma Octanus IV where a probe attached to theUNSCIroquois and revealed thehuman presence atReach. This culminated in theFall of Reach.^[1]

Trivia[edit]

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