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 |

Just a bit of fun using Google Sketchup. Never used it until about an hour ago, it's amazing!
The GMC is somethign I already have. It's a £20 digital camera that takes 1280 x 1024 images at pre-determined intervals. It runs from a single AAA. The Convex Mirror would be the sort you can get to stick on your car side mirror to see blind spots. Having the GMC as a stand alone component is a good move for redundency. I want to see if I can make the GMCSA from what was 'cat cam' - some foam, a mirror ,and then put it in the freezer to see how long it can last. I got some foam insulation yesterday - and it's too thick really - 50mm thick which is a bit crazy. The thermal properties are amazing, just leaning up againt it you feel hot after 5 seconds because it's not letting heat get away, it's bizarre. Anyway - if anyone wants the GSU file - let me know I'm still aiming for something like 10 x 10 x 15-20 internal space - and then if the foam is a few cm thick, you can always carve into it a little. Weather permitting, I'll be going to Cambridge next Sunday to see a launch by James - http://www.pegasushabproject.org.uk/ - |
