An Astronaut's View of Space Station Tech 115

Posted by CmdrTaco from the i-can-see-my-house-from-here dept.
An anonymous reader writes "Here's a chat with a NASA astronaut about how they fix system outages on board the International Space Station, what kind of computing tech they use on board, and how he would like to see the iPad used on the ISS." He talks about using 5 year old laptops because they had been tested to handle the stresses of space travel, as well as the importance of being able to read emails and send pictures to family while aboard a space station for months at a time.

    Not that I bothered reading it.... if they are quoting astronauts advocating ipads, it is clearly just yet another propaganda piece pushing mindless consumption. Very few people will operate a computer in zero gravity, and whilst it is possible that no keyboard and being stuck in a closed playground could be good in space, I should think the ipad would suck as much as when on the ground.

    • I love my iPad, but one of its main advantage over my laptop for me is that the ipad weighs much less and so is much more portable. But in space since everything's weightless, that benefit goes away, so it doesn't sound that much better.

        A few interesting things about GPS in space:

        a) All GPS receivers capable of sensing a position higher than 11 miles or a velocity higher than 515 meters/sec are classified as munitions and require state department licenses to export... Pretty much no consumer GPS receiver, including the iPad is going to be able to find itself in orbit. OTOH, the Space Shuttle itself uses GPS for space navigation, and I'm sure the ISS has a GPS receiver on board as well that can find its own location.

        b) The GPS satellites orbit at 20,000 km, while the ISS orbits at 350km... The strength of the signal isn't really all that affected.

          Given a constant medium, sure, that would be correct. On the other hand, going just 2 meters underground will weaken the signal more than your entire 20,000 km range.

          Not to say that you're wrong - I'm not sure how much more signal degradation you get due to atmosphere vs in a vacuum - but it's not as simple as you're making it sound.

            Well, your reception certainly isn't going to get worse by putting less between you and the transmitter.

            • Ah I see the problem. Most of the comments I was reading were suggesting that reception would improve. I never actually read the one you were responding to. Whoops.

        • The restriction on civilian GPS receivers is that the receiver should be able to show a position higher than 11mi, or a velocity greater than 515m/s, but not both simultaneously. A number of GPS manufacturers, however, have implemented this in a somewhat slack fashion and used || instead of &&.

      • Since GPS is in space, I'd think you'd get very good GPS reception on ISS.

        That's assuming they'd get a 3G iPad, my Wifi only work iPad doesn't have GPS.

      • The orientation sensors used in Android and iOS devices are MEMS accelerometers, which only measure acceleration in each of the 3 axises. On Earth, gravity provides us with a constant 1g acceleration in a fixed direction, which is used to calculate the orientation of the device.

        In zero G, and just floating there in front of you and not moving, the accelerometer will show a reading of 0g in all three directions, indicating that the device is in free-fall, which is quite correct.

        So, yes, the orientation senso

        Yeah, they'd weigh the same, but they definitely aren't used the same. I would think the ipad (or any tablet) would be more convenient than a laptop since it is designed to be used with one hand while holding it with the other. Laptops most likely need to be fastened to the ISS in some way in order to type on them. You can't simply use a laptop while floating in zero-g as it'd need a force to counter the force of your typing. If the astronauts were to have tablets instead, then they could take notes (or whatever astronauts do on the ISS) from any orientation.

        Absolutely. The ISS doesn't have any computers built into it, and all flight computing, life support control, etc. is done on the same computers that the astronauts use for their email, so computational power is paramount.

    The computing hardware built into the ISS is not really something you want to be "upgrading" every few years. The "if it ain't broke, don't fix it" principle applies here: The hardware is running multiple systems critical to life. If it works fine now, don't mess with it and expose yourself to the possibility of the new system having bugs which could kill people.

    Less critical functions can be run on a portable computing device like a laptop. These can be upgraded more frequently since they don't have to be tested as thoroughly as the mission-critical systems are. Due to the fast pace at which computing technology improves, this frequently results in situations where the portable computing device is more powerful than the built-in systems. On many early shuttle flights, the most powerful computer on board was the HP-41 calculator [wordpress.com].
