Re: [Phys-l] homemade spacecraft!



Right!

The instructional mgr. at the Univ. in Ogden (UT) does this w/ balloons sufficiently high to well show that the E. is ~ a sphere. His pics are posted, but I'm too ... to find the URL, etc.

Radio amateurs have apparently been doing this for years. (Need
foxhunt beacon to find your camcorder thirty miles away in a field.)

I think today that hobbyists put GPS onboard, then rig a transmitter
to send serial data, so you can just go to the GPS coords.

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?
