Passive PCB Mounted Thermal Switch
A printed circuit board (PCB) generates heat during operation. In a vacuum this heat can only be rejected by conduction and radiation. In order to reject heat effectively the PCB needs to be thermally conductive to the electronics enclosure. However, when the enclosure temperature gets too low, too much heat is rejected from the PCB and it can fail. This thermal switch has been designed to allow for heat rejection when the PCB is sufficiently warm but then greatly reduce heat rejection when the temperature gets low enough.

Passive PCB Mounted Thermal Switch
A printed circuit board (PCB) generates heat during operation. In a vacuum this heat can only be rejected by conduction and radiation. To reject heat effectively and avoid overheating, the PCB needs to be thermally conductive to the electronics enclosure. However, if the system rejects too much heat, or not enough heat, either can result in system failure. The thermal switch will be able to regulate the amount of heat the system rejects to stay within the operational temperature range.

Handheld Universal Lunar Camera
The Handheld Universal Lunar Camera (HULC) project is a proposed project to fly a commercial off the Shelf (COTS) unit to be used in all aspects of the Artemis Program. This will include use on Orion, Gateway, Human Lander, and on EVA operations at all locations, which will include lunar surface use. The HULC is planned to be COTS with minimal modification; extensive testing must be done to ensure usability in lunar environments.
