Emissivity
Thanks, Richard. On a slightly different (but related) topic: has anyone seen emissivity data for aluminized cuben? We seem to make the collective assumption that it will perform like a space blank...

Aluminized cuben
Nathan or Richard, which mylar surface is aluminized? Sorry if this is made clear in an earlier post and I missed it. Is the aluminum surface inside the laminate (on an inward-facing mylar surface)...
