    First iPhone in space to launch with last shuttle mission

    When the final space shuttle mission launches later this year, two iPhone 4s will be on board.

    The iPhones will be running an experimental app called SpaceLab for iOS, designed by Odyssey Space Research. Once the space shuttle Atlantis docks with the International Space Station, crew members will use the iPhones to conduct four experiments, using the iPhones’ cameras, gyroscopes, and other sensors. In addition, the step-by-step instructions for each experiment are contained within the app, so astronauts won’t need printed instructions to direct them.

    “I’m pretty sure this is the very first iPhone to go into space,” said Odyssey CEO Brian Rishikof.

    The iPhone 4 has been certified for spaceflight and will be shipped to space by NanoRacks, a Houston-based company that provides hardware services for the U.S. National Laboratory, which is part of the ISS.

    The inspiration to create an iPhone-based space experiment came when the iPhone 4 debuted in 2010, Rishikof said. The new model includes a gyroscope.

    “For the kind of work we do, that suddenly made it a far more interesting platform,” Rishikof said. That’s because Houston-based Odyssey’s business is developing software and simulations for guidance and navigation used in several spacecraft; a gyroscope meant that the iPhone could potentially be used to determine a vehicle’s orientation in space as well as its position.

    Rishikof emphasized that the iPhones were being used as an experiment, not for any mission-critical guidance systems.

    SpaceLab’s four experiments:

    A “limb tracker,” which lets astronauts take a picture of the Earth’s limb (its curved edge). The app then estimates the iPhone’s altitude.

    A sensor calibration tool that uses camera images plus multiple sensors to calibrate the phone’s gyroscope and accelerometers.

    Latitude and longitude estimation using photos of the Earth and matching them to wireframes of coastlines.

    A test to see if space radiation affects computer memory by watching for unintended changes to single bits in the iPhones’ RAM.

    SpaceLab for iOS is also available for Earthbound civilians. In the public version, some features of the app will be simulated, since we unfortunately suffer from the effects of gravity. The app is $1.

    NASA has tentatively scheduled the final space shuttle mission, STS-135, for a July 8 launch.
    And in case you were wondering, yes, the iPhones will be put into airplane mode before liftoff.

    Am I the only one is getting fed up with this "iPhone-miracle-device" behaviour? Sure, it is a nice device, but it is like it is the only device of its kind in the world, and nothing is worth anything if it does not involve the iPhone in some way...

    A “limb tracker,” which lets astronauts take a picture of the Earth’s limb (its curved edge). The app then estimates the iPhone’s altitude.
    This is just simple line detection and basic geometry. There is no need to have the iPhone on board for that: feed it the same image right here on earth. In space, it would also be much easier as the curvature is much more pronounced (greater altitude), so making it work down here is a far greater challenge. From that distance, it is something we might expect our students to be able to produce!

    A sensor calibration tool that uses camera images plus multiple sensors to calibrate the phone’s gyroscope and accelerometers.
    There are many other devices out there that could be used for the same purpose. I also doubt the gyroscopes and accelerometers in any phone are that accurate. And this could be done right here on earth (zero G should have no effect on the gyroscopes, but it might on the accelerometers). Again, the point of using an iPhone seems a bit commercial rather than technical.

    Latitude and longitude estimation using photos of the Earth and matching them to wireframes of coastlines.
    Just like the first experiment: line detection, image matching, ... Just basic image processing. And the iPhone is a small computer, so for sure you can make software to do this. There is no need to even do this in space: just feed your algorithm the images.

    A test to see if space radiation affects computer memory by watching for unintended changes to single bits in the iPhones’ RAM.
    This is very important, but should be done in a much more controlled test lab: verifying different levels of isolation, determining if some locations in the chip are more affected than others. And it is already known space radiation has an impact on ICs... so seeing if it has an impact on an iPhone is clearly is only for the public relationships factor.

    SpaceLab for iOS is also available for Earthbound civilians. In the public version, some features of the app will be simulated, since we unfortunately suffer from the effects of gravity. The app is $1.
    So you can simulate the experiments... effectively, this means the app is pointless... probably like the majority of apps out there.

    So, first and third experiment are basically software development, second and fourth would require a better testbed to be useful...

    Sorry for the rant, I'm just so fed up with this whole iPhone worship.
