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 |

Actually - the FAA ( and I'm looking up the UK version, the CAA ) are fairly liberal with these things up to a certain mass. Many of these balloons have ( and indeed one is going up today ) been launched from the UK - in a typical 2hr up 30 min down flight - you'll cover something like 30-100 miles. Launching from the western UK ( Wales ) would put you back down in central UK.
I think the flight reg analogy is that if you're not going to launch something heavier than a duck, then what's the problem as no law's going to ground all the ducks and swans at 12000 ft \ I got bored - I went out to Maplin ( local electronics store ) and thought that I might need some soldering practice, as whatever we make I'm sure some soldering - even if just for power leads - will be required. They've got LOADS of cheap little kits - so I found the only one that seemed to make any sense for a payload...a small super bright white LED strobe kit. I figure I can rewire the LED's to be external to the WEB on cables running out the box, and perhaps on strut I thought we could mount a WAM for self portraits and in the case that we're still looking for the payload at night...it might help find it. Three little transistors, two capacitors, half a dozen resistors, a variable resistor and a brace of switches - cute little setup really (and suprisingly bright) Sorry - crap pics - using my cell phone's camera. And I've found a supplier for a suitably sized parachute for a 2kg payload ( 36 inch diam ) - it's on its way. Doug
