hype7 writes "An Australian student at Deakin University had a fascinating idea for a final project — to send a balloon up 100,000ft (~30,000 metres) into the stratosphere with a digital camera attached. The university was supportive, and the project took shape. Although there were some serious hitches along the way, the project was successful, and he managed to retrieve the balloon — with the pictures. What's really amazing is that the total cost was so low; the most expensive part was buying the helium gas for approximately AUD$250 (~USD$200)."

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.

Wow - what a complainer. Sure it's not that novel, but still cool and you just have to shit all over it. He built his own microcontroller system - that's not that trivial.
As for your suggestions:
1) a stabilizer would either drain the batteries or freeze up with the low temperatures. Adding complexity with little benefit does not make it better
2) might be interesting. IR might just show that the earth is warmer than space. Ooooo now there's science!
3) sure, put lasers on a balloon that can fly into airline flight paths. Now that's safe.
4) real time image analysis. You do realize what the computing capabilities of a microcontroller are, don't you?
5) why implement the complexity of a wireless grid? Just launch several balloons all time stamped and you can process the data later. Again, needless complexity doesn't make it better, it just makes the probability of failure much higher and drives up the cost exponentially.
6) something useful? How about a big floating sign saying ACs don't have a freaking clue what they are talking about?
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.
No, it can't miss Earth from up there. I just did the calculations. At 20 miles up, that adds only 32187 meters to the radius of the Earth. Working through the math, it means that the acceleration due to gravity is 9.7 m/s^2.
At sea level, the acceleration due to gravity is 9.8 m/s^2.
Thus, sea level escape velocity is 11201 meters per second Escape velocity at 20 miles up is 11152 meters per second.
The difference is 49 meters per second, or 110 MPH.
Now, to pick a gun at random, let's choose the US Army's M198 Howitzer. It's an artillery piece that fires projectiles at approximately 760 meters per second. So you need to have a much bigger cannon, and a much bigger balloon.
I don't see why ANY of this is a big deal. Joe Kittinger RODE a balloon up over 100,000 and then jumped out, with cameras rolling. OK, they weren't digital cameras, and the whole job cast a lot more than $200. but it was back in the 60's...
I don't see why that's a big deal. Neil Armstrong went to the MOON in and made it back in one piece with cameras rolling. OK, they weren't digital cameras and the whole job cost a lot more than $200 but it was back in the 60s...
I thought the same thing as well. I'm in Australia, even the people here are calling it a publicity stunt, although, if thats true then I don't understand the actual benefit the family gets with the publicity... aren't they described as a "crackpot" family?
Google is your friend, and can help you find the answer [hawaii.edu]. Ok, maybe not a specific answer, but pretty damned close.:)
I suggest 10 24' diameter balloons, with breakaway tethers should one pop (no need to carry the extra weight of a dead balloon). If that can launch a compact car into LEO, it should be able to take a 6 year old high enough where you won't have to hear him scream. Well, at least until hypoxia kicks in, then it doesn't matter.
Make sure you strap a camera to him, a little something like the Blair Witch Project, except in the daylight, with the only backdrop being the sky. Well, you may have the incidental aircraft in the background. I think a 6 year old and 10 24' balloons may ruin a perfectly good flight. What exactly put that Airbus A320 down in the Hudson? I think the whole bird thing was just a conspiracy to cover up the fact that it was a flock of school kids tethered to weather balloons with cameras strapped to their asses. Oh, imagine the bad press when you have to admit that your A320 just ingested a flock of school children in the engines. Oh, and the mess on the ground. I'd hate to be walking down the street just to get splattered by that. I thought it was nasty when PETA threw red paint on me for wearing a leather jacket? That would just be disgusting.
And as a side note, based on those numbers, it would take about 80 24' diameter helium balloons to lift a 40' city bus. *THAT* would be something hilarious to see, but I'd hate to be under the landing zone. You know eventually they'll pop or leak. Some famous guy said "what comes up must come down", but I think he may have been full of shit. A flying 40' city bus could leave a little bit of a crater. I don't want to think of the logistics of filling the 80 balloons simultaneously though. That's a lot of helium. Just imagine if you got on the bus thinking "Oh, I'm just going to work", and then find that your bus is heading up towards 100,000 feet, and the driver keeps saying "Sir, please stay behind the white line." White line my ass, I'm on a flying bus!
Maybe sometimes you shouldn't ask the questions, because they may be answered and then some.:)
To be fair, it was kind of tough to tell the scale from the pictures of it flying. Once it got close to the ground, it was obvious to anyone who'd seen that one episode of mythbusters like five years ago. But until then, there just wasn't anything to reference its size to, except maybe the skin crinkle, which would have required extensive knowledge of the material to make judgements based upon.
I think that the reason that the newspapers printed this article was because it had a nice story to go with it. These high altitude balloon projects seem to be a bit of a hot topic at the moment. (I'm the Geoff from the Article)
Yes there have been many similar projects done by others for many years - I'm quite surprised that this story ended up going this far. Mine was a Uni project that I went about by myself, there aren't a lot of technical details in the article but the aim of the project from an engineering point of view was to build a data logging system that would function without fail at very low temperatures. Of course I wanted it to take nice pictures along the way, but this was really just because I thought it would be nice to have my own pictures from "Near Space". Other than the electronics/software design that went in to it, I put the system through low temperature environmental testing so that I could prove (mainly to myself) that the system would work before I launched it. I worked on it part time over a year, there was a lot that went in to it at the end.
I encourage others that are interested in this hobby to give it a try, it's a lot of fun and a lot more challenging than it seems. I gave it a go, learnt from it, and now plan another launch. I still haven't decided what to put in to the payload for next time round, so here's a question for the/. crowd:
What would you pack in a high altitude balloon project payload?
well jeff, I'd like to tell that you set-up is almost ready for a Canadian winter. In early 2008 we hit -49 for a couple days;) If you'd like to do any environment testing for future projects, just head to Alberta in January/February.
Well, you see, if NASA can smack the Moon's ass in the dark and get people all worked up over nothing, why not some Aussie dweeb that can't set a camera? Special just means vastly underachieved these days it seems...
Didn't some kids at MIT send a balloon out of the atmosphere... recently?
No they didn't, not even halfway. What's special about this is that neither the summary nor the article make any bogus claims about balloons making it into space.
(Kennedy Flight Center) NASA Spokeswoman Carrice Light stated at a hastily assembled press conference at a local KFC at Tampa Bay, "NASA has done this many times, and will continue to do so." Ms. Light also went on to say that NASA's projects to explore the heights of space are planned to go way beyond the 100KY Barrier,(short for 100,000 yard barrier), but that it still appears to be a major concern for NASA's administrators. "With the tragic passing of Mr. Jackson, 'Moon Wa
It was actually a group of Spanish students who initially did this earlier this year for the first time. http://www.telegraph.co.uk/news/newstopics/howaboutthat/5005022/Teens-capture-images-of-space-with-56-camera-and-balloon.html and it also got slashdotted (and they didn't get the ISO wrong...).
Now that the methodology has been worked out, sending a camera up to 100kft is becoming a pretty common university and ham club team project. Provided care is taken during assembly, the biggest gotchas are while inflating the balloon, and hoping the winds keep the payload over an area with suitable roads.
It'd be neat to see more teams collect additional science, with live TM for extra points. A few years back, a few college students in Beautiful B.C. designed their own UAV [hackaday.com], which flew home after release a 6
Cool, so if we can get a baloon with payloads of say 1/2 a pound pure, which is what.... $20k of cocaine.
Wait for favourable winds/direction. Make sure its blue so it cant easily be seen.
Fire it up, with a tiny cpu (use old nokia without screen/plastic cover running MIDP2 java app).
Once it reachs a GPS region or into USA, deflate one of the baloons to desend not too fast, and sms the gps coordinate 5 seconds before hitting the ground.
its usually the reporters that call it "the edge of space" even the author calls it the stratosphere. I'm part of that Alberta HD video balloon group. We like to call it "Near Space" which is defined as:
"Near space is the region of Earth's atmosphere that lies between 65,000 and 325,000-350,000 feet (20 to 100 km) above sea level, encompassing the stratosphere, mesosphere, and thermosphere."
We're not in space, but were way up there!

Mother fuckers, I attend the Burwood campus at Deakin University and I'm an SIT student and I wanted to do something very similar (Attach some Arduino data logging for sensors etc.) and they told me no and didn't want to hear anything more about it even though I said I could fund it myself, instead this tool who can't even set a camera right does it with University support. I attend the damn university and not even I get to find out about this stuff until I see it on Slashdot! Fuck the "Deakin Experience", they don't give a flying fuck about anyone else other than postgrads and masters students.
I can just see the Australian patent lawyers revving their engines again. Thank goodness those MIT students did this before and have prior art so we won't see another stop-stealing-our-toy-designs lawsuit.
This isn't something new, my undergrad university (DePauw University in Indiana) has been sending balloons 100,000 feet (I think our record is about 110,000) with digital cameras for about 5 years:
http://www.depauw.edu/acad/physics/base/ [depauw.edu]
Each student had a pod with their own designed experiment, a requirement for a physics course.
We bought our system from Taylor University, who have been doing it twice as long.
The black gadget at the top of the picture appears to be one of my OpenTracker+ kits - I see that Geoff ordered a couple back in May. So I'm going to take this opportunity for a brief shameless plug:
His main payload computer looks to be wholly custom-built, but the OpenTracker+ (that handles taking data from the GPS receiver and transmitting it over the radio) is an off-the-shelf kit that takes maybe an hour to build, if you don't want to pay an extra few bucks for a pre-assembled unit.
It's based on the Freescale MC908JL16 microcontroller, the full source code is available under the BSD license, and it'll compile with the free version of the Codewarrior IDE. It's got a serial bootloader, so there's no need for a device programmer. If you're comfortable with C programming, it's a very cheap way to build a simple, customizable tracking and telemetry system. Or just run the regular firmware and it'll do a whole bunch of stuff without modification.
Its larger cousin, the Tracker2, does a whole lot more and the code is released under GPLv3, but unfortunately you can't compile it with the free version of the IDE. It does include a simple scripting engine, though - written mostly so balloon builders would stop bugging me with minor ad hoc changes for their particular setup.

It was actually a group of Spanish students who initially did this earlier this year for the first time. http://www.telegraph.co.uk/news/newstopics/howaboutthat/5005022/Teens-capture-images-of-space-with-56-camera-and-balloon.html and it also got slashdotted (and they didn't get the ISO wrong...).

Another Day, Another Balloon Cam (Score:2)
Now that the methodology has been worked out, sending a camera up to 100kft is becoming a pretty common university and ham club team project. Provided care is taken during assembly, the biggest gotchas are while inflating the balloon, and hoping the winds keep the payload over an area with suitable roads.
It'd be neat to see more teams collect additional science, with live TM for extra points. A few years back, a few college students in Beautiful B.C. designed their own UAV [hackaday.com], which flew home after release a 6

Cool, so if we can get a baloon with payloads of say 1/2 a pound pure, which is what.... $20k of cocaine.
Wait for favourable winds/direction. Make sure its blue so it cant easily be seen.
Fire it up, with a tiny cpu (use old nokia without screen/plastic cover running MIDP2 java app).
Once it reachs a GPS region or into USA, deflate one of the baloons to desend not too fast, and sms the gps coordinate 5 seconds before hitting the ground.
Drive up and pick it up at leasure.
Im sure if you write up a nice prospec

I can just see the Australian patent lawyers revving their engines again. Thank goodness those MIT students did this before and have prior art so we won't see another stop-stealing-our-toy-designs lawsuit.

Open source tracking (Score:3, Informative)
The black gadget at the top of the picture appears to be one of my OpenTracker+ kits - I see that Geoff ordered a couple back in May. So I'm going to take this opportunity for a brief shameless plug:

His main payload computer looks to be wholly custom-built, but the OpenTracker+ (that handles taking data from the GPS receiver and transmitting it over the radio) is an off-the-shelf kit that takes maybe an hour to build, if you don't want to pay an extra few bucks for a pre-assembled unit.
It's based on the Freescale MC908JL16 microcontroller, the full source code is available under the BSD license, and it'll compile with the free version of the Codewarrior IDE. It's got a serial bootloader, so there's no need for a device programmer. If you're comfortable with C programming, it's a very cheap way to build a simple, customizable tracking and telemetry system. Or just run the regular firmware and it'll do a whole bunch of stuff without modification.
Its larger cousin, the Tracker2, does a whole lot more and the code is released under GPLv3, but unfortunately you can't compile it with the free version of the IDE. It does include a simple scripting engine, though - written mostly so balloon builders would stop bugging me with minor ad hoc changes for their particular setup.
