Primarily a "how to" video for the folks that will be preparing & launching the payload (sorry it's not more polished), it also give you a taste of how the payload is put together and functions. For more information, visit the HALE website at:
Summary: The idea is for the "Lil' Joe" payload to be carried up to roughly 80,000', and then cut free from the main payload string to perform an independent free-fall, deploying its own parachute after a brief (20 second to more than a minute) free-fall period. At altitude the pressure is approaching 1% of sea level pressure, and the temperatures are very very cold (-50° C or lower). All control functions are programmed using NXT-G running on a LEGO NXT, and to find the payload after the drop a SPOT unit is along for the ride.
And yes, of *course* there's a minifig riding along :)
