Putting the Raspberry Pi Into Orbit 82

Posted by timothy from the big-slingshot dept.
Jack Spine writes "The Raspberry Pi is likely to be blasted into space, according to project founder Eben Upton. The $35/$25 credit-card-sized single-board educational computer could be used in sounding rockets, satellites, and high altitude balloon tests, according to Upton. Raspberry Pi has proved wildly popular since its launch, with one developer planning to build into a model boat to sail it across the Atlantic."

      Because everyone does it these days. Every other university has a student "space exploration interest club" who launch a helium balloon to "near" space, snap a picture and recover their "satellite". Google launched 7 such balloons with a bunch of Android phones onboard to prove that "Android works in space", and the iPad pouch creators launched one to show how their pouch/case protects your iPad in the event of it accidentally falling from space. A couple of years ago it was "it can run your toaster", no

    • From Raspberry Pi distributor element14:

      Registration for the Raspberry Pi has now closed. We are currently ensuring that the large number of customers who registered their interest over the final few days of registration have sufficient opportunity to order their Pi, and will be opening to general Raspberry Pi orders mid July.

      If you signed up at the launch, you'd have one by now, and if not, you can get one quite soon.

    I have been playing with my Raspberry Pi for a little while now, mostly as a media center and like the way the CEC package works with CEC compatible TV, turns on the TV and you use the TV remote. With all the developing going on, I suspect that before too long I will be able to put together a Raspberry Pi with an ipcam viewer app that can turn on the TV when a proximity switch is activated. I already have an Adroid app for ip cameras that also support TPZ , which could be rewired along with a inexpensive

      It is ridiculous to say you could use this for a satellite. Yes, you could throw this up into orbit in a satellite and it would probably work for a little while before radiation issues. If you are buying a multimillion dollar rocket, you can afford to throw down more than $35 for your satellite bus. If you are hitching a free ride on rocket bought by a third-party and just wanted a few day of LEO orbit, then yes Raspberry Pi could be an option. If you have a free ride to space, you might want to spend a

        You probably can't use directly a Raspberry-Pi board in space application (radiation is not the only problem, you also have thermal issues, ...), but using not specificaly space-hardened processors could be possible in a majority/median voter system. But you need to remplace one space hardened processor with a bunch of normal processors, and have a specific electronic for the voter system. And put a shield to lower the radiations.
        • Why can't you use Raspberry Pi (or other COTS electronics) in space? Just because radiation and heat are issues, does not mean they are automatically terminal issues.

              The mounting points is a serious stumbling block; certainly moreso than radiation or temperature. Launch vehicles that don't have squishy human payloads aren't shy about peaking at 15Gs (SD cards can and should be glued in place. We already investigated this.) I never did mechanical design - but unless I hear otherwise I wouldn't consider it a fatal problem. If thermal and mounting do become really p

I think that these are not the same things (although they are related) the sunlit side of the satellite could be a toasty 100 degrees C, while the dark side could be -100. If the satellite is spinning but not fast enough perhaps some traces could expand and contract enough to break. Meanwhile without air to conduct heat, a single small component on the board could overheat and fail.

      • A little knowledge is a dangerous thing. Yes, thermal control is a problem. No, it is not a showstopper that stops you using COTS electronics in space.

    • Radiation in LEO isn't that bad. COTS components don't just die the moment they leave the atmosphere. If every single event upset translated into an actual fault, they wouldn't be very reliable down here on earth either.

      Cubesats have flown with COTS hardware - and they have done it through orbits that pass through the south atlantic anomaly. Yes, there are reliability issues - but certainly not showstoppers.

  • I wonder how they plan to hold it down, given that the Pi board's lack of mounting holes is something of an annoying fail. There's not even much space on the edge of the board to clamp it, which seems to have created an interesting challenge to those now making Pi-cases. Although in this application, I assume most of the connectors would be removed, giving a bit more spare board-area.
