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)

Here's a more-or-less self-explanatory table of altitudes with some notes. The only odd column here is the one called deg - this is the dip from the local horizontal at the listed altitude to the Earth's horizon. Higher the dip, the better the curve!

There's a few potential Mission Success Criteria here that would be good to see: personally, I think that the old tropopause feels almost too achievable with off-the-shelf weather balloons. I'd be, well, tempted to aim just a little higher...not too much, but still...
