Australian Student Balloon Rises 100,000 Feet, With a Digital Camera 174

Posted by timothy
from the shame-about-the-iso-setting dept.
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)."

        100,000 feet is nothing special. They regularly go higher than that.

          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".

            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?

            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.

          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.

        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:

  • This would be awesome for OpenAerialMap [openaerialmap.org]. It's a shame there's no freely available photography dataset of the world yet.

      Actually, that isn't quite true. All of the Landsat [wikipedia.org] data is available in the public domain as it was produced with resources and funding from the U.S. government. This can be found here:

      http://eros.usgs.gov/ [usgs.gov]

      Unfortunately, the data isn't packaged and set up to be convenient to folks who want to use it. The copyright information about this satellite data can be found here [usgs.gov] that does confirm it is in the public domain. Some folks have obtained this data and then charged fees and "copyright" for their modifi

        Interesting post, yes, it would be useful to get those old photos declassified.

        Also, some of the higher resolution images found on places like Google Maps are made from commercial imaging satellites, which is protected by copyright.

        That's what I meant, Landsat is quite low resolution (I don't find it particularly difficult to use, with JOSM and other OSM editors map data can be easily laid over landsat images). The Google Maps type images are nice, high resolution, and make mapping areas very easy, it would be good if there were a way to use cheap balloons to gather these type of images for large areas and then release them as part of a larger project with

  • Same thing happened to me a few years ago at Disney World when I was attempting to juggle a hot dog, my digital camera, and some Mickey Mouse balloons I had bought for the kids. The strings got tangled in the camera and when I went to munch on the hot dog, the balloon slipped from my fingers and I watched helplessly as my camera sailed into the unknown.

    But it gets better!

    Several weeks later, I received an anonymous UPS package containing my digital camera! A quick glance showed that the Disney shots

    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:

    http://www.argentdata.com/products/otplus.html [argentdata.com]

    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.

There are running jobs. Why don't you go chase them?
