Re: [Phys-l] homemade spacecraft!

A few years ago ,on the Yahoo discussion group, I started up a Solarballoon discussion group. I've had several people, who are HAM radio operators, track their solarballoons and you could follow along on Google maps. I don't think they got up nearly as high as the He balloons, perhaps 10 miles, but some of their ranges were impressive. I remember following on that was launched from southern Michigan and landed that evening in north or central Georgia.

If anyone is interested, I do have a Google Earth kmz file that shows the path of someone's solarballoon that I could email as an attachment. It's interesting to see the path...kind of a figure 8. Just send me your direct email address.

Have a great day!

As someone else has already noted - there's a lot of this going on these days.
FAA regs allow for lightweight packages with no rigamarole (sp?)

I'm surprised at how many groups are still using He (a VERY limited
and nonrenewable resource) instead of the more buoyant H2 alternative.
And the H2 adds even MORE excitement to an already exciting adventure ;-)

A colleague just sent me this 7-minute video clip of a balloon with a
camera attached that went up into space. The balloon later expanded,
exploded, and the camera went into free fall. Very interesting! Very cool!

Might be a good project for students?
