I estimate 10 million of these balloons have been launched with sensing instruments and radio telemetry. (Twice a day, more than 50 years, 800 sites currently but hundreds since the 1960's= 2x50x365x400 = more than 10 M). There is nothing very interesting about these students doing it.

These camera stories are kind of "eye-candy" science: pleasing to look at but not much substance. There is no trick to launching a balloon with a camera attached... and apart from being outright fun, there isn't any research advancement either into atmospherics or into the engineering technology of launching an instrument package with a balloon. They even do it the easy (safe) way with helium instead of hydrogen. BTW, this is kind of wasteful. Helium is a scarce resource.

The current telemetry packages attached to the weather balloons contain a telemetry transmitter, a GPS receiver, and humidity/temperature sensors. This provides wind speed, direction, altitude, location, temperature, and humidity.

Now, if the students did something interesting such as:

1. Adding in a light weight low-cost stabilizer and remote control package to steady and aim the camera
2. Modify the camera with filters to observe a parameter that is not usually measured (ie: perhaps infrared, uv, etc)
3. Attach a laser and test out a methodology for measuring parameters within a range of the balloon
4. Create a 360 scanning system and analyze the images in real time to provide cloud formation information
5. Created a wireless grid that co-ordinated and measured information from multiple synchronous balloon launces in the same relative area
6. or something else creative, imaginative, and useful

THEN this would be an interesting story. Else just fluff.

If /. publishes another "student loses camera attached to stupid weather balloon" then I'm going to start submitting pictures of our pets. "Man uses $1000 camera to take thousands of pictures of children and dogs".

Umm, yeah, I'm gonna need a citation on that.

Ahh, the ways we could piss off the FAA. I know some of the regulations, and that's half of why I haven't built half the stuff I want to.

Not too sure about Australia, but here in NL we have much the same regulations.

If I were to 'do the right thing' and write to the aviation authorities here saying I intend to let loose a big ol' helium balloon capable of reaching 30,000 feet and higher, with a digital camera attached, they would smack me down citing all sorts of safety regulations (camera into jet engine = potential loss of engine power and all that.. they tend to be less squishy than birds - which do enough damage as it is).

But if I were to 'just do it', I get to have a fun project, a great experience, and possibly awesome results to share with friends and indeed the world. Last, but not least, very little chance that the authorities would come after me after-the-fact (unless the thing -did- get sucked into some jet engine or otherwise disrupted air traffic).

The same applies to ventures into abandoned factories, for example. It's not your land, not your property, you're legally trespassing and if caught the owner will probably tell you to get the hell off of his property.. but you'll already have the experience of going there, maybe photos, etc. If you were to write first, you've got odds against you.. if the owner says 'sure, go ahead', and you get into an accident at the site, they'll be liable.. odds are, thus, that you'll get a big fat "no, you may not go onto my property".

Rules may not be meant to be broken, but life tends to be more interesting when you do break them.

Duh. Are you serious? That was an expensive project with plenty of manpower. This was one guy and his girlfriend spending a few hundred dollars.
