Technical specifications[]
A class-4 probe
The probes were essentially modified class-3 probes and had a range of 3.5x106 kilometers. They were powered by a vectored deuterium micro fusion engine with an expanded deuterium storage for maneuvering which could propel them at warp 0.6. They had triple-redundant particle- and field-detectors as well as a group of sensors for stellar atmosphere analysis. (TNG reference: Star Trek: The Next Generation Technical Manual)
In addition to that, these probes had six launchable radiation flux sub-probes on board and was also usable for non-stellar energy-phenomena. They could only remain on a terrestrial planet for a limited amount of time. (TNG reference: Star Trek: The Next Generation Technical Manual)
