We began talkin about a UMSF balloon - and who know what might happen if enough people think about something hard enough, thoroughly enough and long enough. How's about this as a starting point. http://vpizza.org/~jmeehan/balloon/ with http://www.chem.hawaii.edu/uham/part101.html as an important regulatory start point (I'm going to look up the UK regs for this as well) http://www.srcf.ucam.org/~cuspaceflight/nova1launch.html is also very impressive - all done in the UK This http://www.makezine.com/blog/archive/2007/...video_podc.html is particularly impressive - I like the multiple-cameras slant. Anyway - thought I'd get a thread going - this is an idea I like too much to let it gather dust in a corner - the one thing that I think would be nice to achieve is self-portraiture of some sort - think Beagle 2's WAM etc....perhaps in a corner of the FOV of one of/the imaging system. What sort of limit's should we set ourselves? 1kg 10x10x20cm? (sort of 2U Cubesat-on-a-diet budget) Doug |

Payload wouldn't be thermally 'controlled' per.se - but something like a foam (there's 3cm thick foil covered foam available at my DIY store) cube which would thermally insulate it from the cold - and then the electronics inside would hopefully keep it fairly warm simply by using up the Whr's.
I knew someone would start thinking of logo's and names before we got too far Doug |

Doug Yeah, that'd help. Main concern here is electrical connectors. Probably a good idea to seal them with ScotchGard or RTV, which in addition to adding another insulation layer to minimize thermal contraction/expansion would also prevent moisture intrusion/condensation. -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.
