Class-3 probe

A class-3 probe or more specifically class III planetary probe was a type of probe used by the Federation Starfleet in the 24th century.

The probes had a range of 1.2x106 kilometers. They were powered by a vectored deuterium micro fusion engine which could propel them at warp 0.65. Their sensors included terrestrial and gas giant sensor palettes with material collection and return capability and a submodule for chemical analysis on board. 

In addition to that, these probes had a limited-SIF-enhanced hull and were fully capable of terrestrial landing and subsurface penetration missions. They could survive missions in a gas giant's atmosphere up to a pressure of 450 bar.
