Covenant spy probe
From Halopedia, the Halo wiki
Covenant spy probes are small, softball or baseball-sized automaton machines used by the Covenant for reconnaissance and intelligence roles.
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.
The spy probe is similar in function to the UNSC's telemetry probe.
