  Great Idea Biggie, and do contestant have to share their designs? 😀

  Well it's just an idea and it seems that it'll require lot of planning. The contestants will have to submit their design and also submit photographs as well!

  Yes, this is not small contest as the task is not easy game. 😉 we've to manage it very well with full planning. 😀

  How are we supposed to get the camera to 50,000 ft?

  That's the Challenge i think. 😉

  The simplest solution is a tethered balloon carrying two cameras (hoping at least one works).
  I did a rough calculatrion using nylon rope for the tether. The crucial factors are the weight and break strength of the tether.
  The following is what came up: (Lengths are from bottom up).
  Lengths for different dia ropes in series
  5000 metres 5 mm dia
  1000 metres 6 mm dia
  1600 metres 10 mm dia
  1000 metres 12 mm dia
  1000 metres 16 mm dia
  1200 metres 22 mm dia
  
  The design includes a factor of safety of six.
  
  One can get lower end 12 MP cameras @ 2/$100 on sale. This leaves $400 for the rope, balloon and the small electronic circuitry to trigger the cameras. May be workable.

  There lies the challenge. 😀
  
  I'm going to need more time to see whether we can launch this challenge. In the mean time, I'll invite more ideas similar to this one.

  It may be possible to optimize this by having three balloons in series, each at 5000 mtrs. In this case we need to use only the 5 mm rope with savings in cost and ease of deployment.
  
  Another wacky idea is to have a free floating balloon, use an altimeter to trigger the shot as the balloon crosses 50 K feet and send the image by telemetry. May be a cellphone camera and image transfer. We will lose the gadget though as there is no way to recover it within a $500 budget.

  I'm abashed. There is nothing new under the sun, is there?

  These guys did with $150 😏, even being able to recover device via GPS -> #-Link-Snipped-#
  
  $500 is more than enough to carry this out 😀
  
  In short, we can list what we need:
  - Weather balloon (and the permission from local aviation authority)
  - Helium gas
  - GSM phone with GPS + Camera capabilities and good battery (or separate camera)
  - Altimeter (optional? we can estimate altitude when balloon bursts)
  - Light sturdy box to protect and insulate components
  - Small parachute
