Speaking about solar balloons, these guys are supposed to launch one tomorrow.

Don't worry guys. I have heard rumors that we're going to trade that old craft in for a restored classic model. So no loss if we lose it.

Well, do tell!
 Like every other California resident, I live for previews of concept vehicles...hell, in a way, I am a concept vehicle...

I've got a Davis VantagePro weather base station that I'd be willing throw into any effort. Couple it with a flash memory datalogger (which would probably survive a hard impact) and you could get temp, pressure, rel humidity weather data all the way up and back.
The whole package weighs in at 830 g. The batteries might work better if they were thermally isolated. I have no idea how the system would work at very low temperatures and pressures. But that would be easy to check in a laboratory. -Mike -------------------- Some higher resolution images available at my photostream: http://www.flickr.com/photos/31678681@N07/

This is a fun idea to contemplate! I know that there are balloons that can target an altitude, and therefore have some control over where they drift. For example, Space Data uses balloons to create low-budge com "satellites" that drift over target areas. I do not know how much more expensive those balloons are, but it is fun to contemplate a long drift time to accomplish something more interesting than just reaching a high altitude.
Since we have interested members in both North Carolina and California, we could consider longer flight paths? We could organize with amateur radio clubs to help track, and if we need to crash land somewhere remote, there's an active community of "geocachers" who'd love to hunt for something so unique and recover it. I suppose power supplies would be a problem for such a long flight. Are there light weight solar panels that can power the 8-watt APRS transmitter and TBD science payload? Are there cameras with really long (5+ hour) battery life? |
