Aspects of the present disclosure relate to an extendable conductor assembly. A conductor of the extendable conductor assembly may be extended (e.g., into a thermal target, such as a preexisting or a newly created feature of a planetary body) and used to thermally couple a rover, vehicle, fixed installation, or other hardware with the thermal target. Thus, the temperature of the hardware may be managed via heat transfer to/from the thermal target. For instance, heat may be transferred from the thermal target to maintain the temperature of the hardware under cold conditions, while excess heat may be transferred to the thermal target under hot conditions. As an example, a rover may form a borehole in the lunar surface, in which a conductor may be extended to facilitate heat transfer between the rover and the Moon accordingly.
