Clarion spy drones are small probes used by the UNSC that can propel themselves through space under their own power by either remote or computer guidance. They use a variety of sensors and cameras to scan space and transmit data to any ship, platform, planet, etc. They are standard issue on most UNSC vessels. They are also one of the few things that can survive a Slipspace ejection with no damage as they are almost pure Titanium-A.
