You'll want to keep everything warm as the box goes up into near space. You'll be above 99% percent of the atmosphere by mass and it gets cold up there. Preferably, you will need chemical heat packs which don't require air to be heated. However, we couldn't find these, so we stuck with heat packs at a small store in New York. You can get these online or at your local hardware store. You'll put these packs next to the camera, MicroTrak AIO, and the PocketFinder.
