A Near Space Photo (and a Leg Lamp)

11 years 7 months ago #251796 by endo342
My friends and I recently launched a weather balloon into near space. Our goal was to send a "Leg Lamp" (from a Christmas Story) to 100,000 feet.


A mechanical failure caused the capsule to become separated from the balloon/parachute. The capsule free fell from 60,000 feet without a parachute and survived! Amazingly, all the equipment inside the capsule was recovered intact. The video shows the details...

On board, we had a Canon SD870 point and shoot (using CHDK in time lapse mode), a GoPro and a GPS tracker. For the time lapse of our setup, I used the Trigger Happy dongle and iphone app set to take a photo every 10 seconds.

We coordinated through the FAA and gave them data to issue a Notice To Airman (NOTAM). According to FAA regulations, if the balloon is under 6 lbs, you don't need FAA approval but it is not a bad idea. Apparently University of Virginia launches balloons frequently so the regional FAA center was used to it.

A lesson learned was to NOT USE ZIP-TIES (even the heavy duty kind) to attach the capsule to the parachute/balloon. The extreme cold and the unbelievable high winds caused them to fail one at a time until the capsule detached from the parachute. The capsule was a Rubbermaid box about the size of a shoe box that was filled with Styrofoam.

Enjoy the video and the photo,
-Allen

I love videos like this. They're so pointless but cool has the underside of a pillow.

Only thing... it would be better if the song didn't have swearing in it. Kids might want to watch this (f-bomb is dropped at 2:57 and maybe somewhere else). Also choose a song without stupid autotune... arrghh why.

Sorry I don't like pop music. ;)
