the inside of the payload box was plenty warm (20°C). the only thing that would need warming would be the exposed lens. We had played with the idea of adding a loop of nichrome wire, or a few resisters out by the lens. Those plans were eventually dropped because the issue is only experienced on the descent (after most of our pictures have been taken) and several people actually liked those images (it added an interesting effect)<br>

</div>Backus uses the air breathing hand warmers and it has worked out well for them.<br>
