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 |

Status update :
Proposal : <2kg payload - on the order of 20 x 20 x 30 cm external + extras. VHF APRS GPS for realtime tracking Multiple internal cameras for mosaicing Horizon-to-Nadir view External camera on independant power supply using WAM or Fisheye lens for self portraiture Standalone system for tracking via SMS / GPRS On order: 36 inch chute ( suitable for up to 2kg ) Microtrack 300, GPS and VHF antenna. 10 x (cheap lot off Ebay) 31x21x24cm external, 26x16x17cm internal polystyrene boxes Wide angle mirrors ( circular and rectangular ) Literature study so I can pass the Fundamental radio licence course to allow broadcast by the Microtrack. On offer: Independance Backup System from Helvick in form of Smartphone with camera and GPS Investigating: Balloon Gas (both kind of important) Power supply Groundstation Gondola cameras - powershots with intervalometer, or other cameras with a shutter-release via a timing circuit. Will multiple cameras carry keep their intervalometers in sync if set off together - or will a timing circuit be needed - and if so, is it worth tying that into the GMC (even though I said I wanted that to be independent) Future options for later flights: Data logging of GPS Lat/Long/Alt, Pres, Temp, Accel ( nice science to tie in to Huygens with accel data) other params. |
