2001: A Space Laptop 226

Posted by timothy from the take-note,-Mir-trip-winner! dept.
Phrogman writes: "SpaceRef has posted an exclusive and detailed article concerning NASA's use of laptops in space including information on the LAN configuration aboard the Space Shuttle Atlantis (with full-color diagrams); lists of software run on the Shuttle laptop computers (with screenshots like this); laptop specs; descriptions of the LAN to be installed on the Space Station; and a lot of other related official NASA materials and links." It's a neat primer on Taking Your Computer to Space, too -- it addresses things like the available power sources, the need for velcro, and quirks of operating in zero G.

    Quoting from the article:
    The PGSC, and everything else inside the Shuttle, needs to be able to be attached to a stable surface to keep it from floating away. Next to duct tape (also known as "gray tape" at NASA), one of the standard means of attaching one thing to another in space is the use of Velcro.

    Heh. Duct tape and velcro are holding our space program together? Seems somehow appropriate. Maybe they can swing over to MIR and patch up some of THEIR problems. Apparently, those stupid russians have been using ordinary masking tape.

    IBM ThinkPad series PGSCs are not the only laptops that have flown - or will fly in space. Computers using Mac OS and Linux have also flown as part of various payloads and are likely to continue to do so in the future. Meanwhile, the Russians will be using a Weiner Power laptop in their portion of the ISS. Other participating partners will likely bring their own laptops.

    I've put a lot of thought into this. Please don't dismiss me right away.

    We all recognize the phenomenal success of Slashdot/Andover/VALinux/OSDN/Plymouth/Whoever-the -hell-they-are-this-month. The company has literally gobs of liquid cash to burn. Thanks to the contributions of unpaid open source developers everywhere, expenses are low. Thanks to banner ad hits, hardware sales, and software distribution (or distrobution if you're a regular here), revenue is high.

    I think the time has come for Slashdot to think big. I mean bigger than the Slashdot Cruiser. With that in mind, I would like to make a modest proposal:

    Paint the Slashdot logo on the Space Shuttle

    It could work: Thanks to 8 years of post-Cold War Democratic cutbacks, NASA is hard up for money. Heck, it's a wonder the Shuttle doesn't already look like something out of the NASCAR Winston Cup series.

    Why not corporate sponsorship of the Space Shuttle? And who better to provide that sponsorship than the site bringing us "News for Nerds. Stuff that matters?"

    Picture it: The Space Shuttle -- painted Slashdot-Green with the /. logo on the vertical stabilizer. We could even paint "This spacecraft Copyright 1997-2000 OSDN" on the side. We could replace all the computers inside the Shuttle with overclocked VALinux boxes. We could supply the crews with /. coffee mugs and Penquin Mints. Missions could be completed in half the time!

    We could even go a step further. We could the entire Shuttle fleet! Instead of "Enterprise", "Endeavor", "Columbia", we could have "CmdrTaco", "JonKatz", and "Hemos".

    Imagine hearing a newscaster saying, "The Space Shuttle JonKatz lifted off this morning. It will remain in orbit for three weeks." Doesn't that make you feel a little funny inside?

    Is the idea of an open-source space program just a dream? Won't you share the dream with me?

  • Well, how would zero-g affect the hardware in a computer? I'm sure it'd have at least some effect on drive spin times. If they kept the main hardware in a vaccum room, then heat would also be a totally different issue. It'd sure be a bitch to use a mouse; gotta keep a grip on it at all times....

  • Exactly. Heat dissapation is a major problem in space. Unless the laptop's heatsinks are properly configured, you could very easily burn out the laptop with only a hour's use.

    Also, I imagine that disk ejection systems and CD drives need to be reconfigured so you don't have spinning discs floating all over the place.

  • We know then that the P-IV will never see use in space, unless they integrate it into the climate control system instead of using conventional heating coils... hell, the mass of the chip and required heatsink (my god!) is probably too heavy to meet payload launch standards anyway...

  • In space, no one can hear you scream.
  • I could just see my orbital apartment.. cables *everywhere*.. yay.... :-)
  • Well, like I said earlier, unless the heat sinks are properly configured, you could very easily burn out the processor by overcloaking it. Part of the problem with heat dissipation in space (and part of the problem with breathing...) is the lack of gravity. With no natural breeze, you get the same air trapped around the processor.

    Now, yes, you can use fans to move air about. But how do the fans work in 0 G? (Well, microgravity, but pretty much the same thing...) I imagine that the fans have to be reconfigured as well.

    I also imagine that the boards have to be reinforced to withstand the forces during takeoff, as well as the screen... the mouse is simple; use the same little pad you normally do with laptops.

  • You can never have too much velcro (Score:4)

    by WillAffleck ( 42386 ) on Tuesday September 19, 2000 @10:33AM (#767824)
    Face it, when in variable G land (e.g. space), it's a really good idea to have too much velcro. And have suits with velcro-ended cables.

    Plus, the lack of air motion is very critical - you want a laptop with good heat dissipation and good fans, plus you need to be sure the fan motors can take varying G forces. Overclocking is a big no-no. Extra RAM is highly recommended.

    Then there's the CD. Remember, no gravity pulling down makes these very difficult to use. Best to have it in firmware or cartridge form. Spin effects can be very hard to clock right in low or zero-G, and it needs to survive the boost.

    Now, when will we see a smart company like Transmeta donate some laptops with low power consumption to NASA, both to sell the chip and to make them hot geek items? Heck, I can see the ads now "As Used By NASA In Zero-G", "The Laptop That Went To Space".

  • I don't think a vacuum room would work. Wouldn't the hard drive crash? If I remember right, the read/write head rides on a small cusion of air extremely close to the disk. Remove the air and the head crashes into the disk tearing up the surface. I suspect they won't be using HDDs in a vacuum environment though. It's hard to say what effect the zero-g will have on them though. I don't think it'll make much difference.

    We're much more likely to see space elevators on Mars before they show up on Earth. Too much chance of lawsuits and terrorists. Just ask Stan Robinson, he's written some interesting stuff on that.

  • You wouldn't; vacuum is a perfect insulator.
    There wouold approximately 0 heat dissipation due to convection.

    Your chip would cook itself almost immediately.

  • Even if I were in a vacuum right now, I would still be comfortable in terms of temperature because I would be radiating heat away approximately fast as I was absorbing it. Besides, if space is so warm, why do the astronauts have heating devices in the suits they wear for EVMs?

    Yes, space is as warm as I think, at least when the sun is shining upon you. When you are in sunlight, the radiant heat which you absorb is quite enormous, quite a good deal more than you radiate away, even if you have good thermal transfer between your "light" side and your "dark" side. The amount of heat which you radiate away is fairly constant, no matter how much radiant heat you are absorbing at a given time.

    If you were in a vacuum, and you weren't in space, you could be correct, however, in space, in the presence of a heat radiating body, such as the sun, will increase your temperature enormously, in the absence of such a thing, you eventually radiate all your heat away, save what little heat is transferred to you by collisions with the few molecules that are present in interplanetary space.

    IIRC, they're not heaters, but more "temperature regulators." Basically they either absorb heat or generate heat as necessary to keep the intrepid spacewalker from burning up at 400 degrees if he's in sunlight, or pretty much freezing to death in the event that he's in shade. However, most particles that one finds in space tend to be highly energetic, since they tend to move at a good fraction of the speed of light. However, there are very few of them per unit volume, and so one's trusty thermometer becomes decidedly un-trusty, and registers a temperature reading somewhere below -200F, unless, of course, the probe is in direct sunlight, in which case, depending on the design, the matter which makes up the probe gets nice and hot and registers quite a warm temperature.

    In the end, the "temperature" in space doesn't really apply anyway, since temperature is a measure of the energy level of a molecule, and space has no molecules. The only reason Earth has a temperature is of course because all of the molecules have a temperature, and the density of those molecules is such that they tend to bang into the temperature sensing device quite a lot.

    Remember Apollo 13?

    Remember Apollo 1? Velcro in a high-pressure, high-oxygen environment is what turned a small spark into a fire that killed three astronauts.

  • A conventional mouse relies on gravity to work.. take away the gravity, the mouse becomes useless

    If you need proof, try this:

    Turn your mouse upside down (or on its' side, any orientation that's not normal), and place a book over the bottom, then move the book around.. you'll notice that the screen pointer doesn't move..

    Ball point pens don't work in zero G either, for similar reasons.

    Optical mice would be a different story

  • how much could you over clock a processor in the coldness of space?

    Not much, cooling devices for CPUs rely on conductive and convective methods of transferring heat away from the CPU. In the vacuum, which I imagine is what you meant by the 'coldness of space' the only available method of heat transfer is radiative. And for a running CPU this isn't much.

  • With no natural breeze, you get the same air trapped around the processor.
    I work in an office like this. With no fan, if I run my fanless Ultralight at 100% (MP3s, SETI@home, D.Net, etc) from the beginning of the day it crashes between 2-4pm. But any fan even vaguely close to the unit will cool it sufficently for surviving the whole day.
  • "nothing mission critical is run on them."

    No system is "mission critical" until the mission relies on it.

    History has shown that it can come down the the number of plastic bags on board. If these systems are "unimportant" to the mission then why are they on board?

    So they're somewhere between "useless mass" and "mission critical." Sooner or later, a mission's success may hinge on the operation of some or all of the computers onboard, perhaps to a purpose that was not forseen in the mission planning phases.

  • I would expect that in 0 or low gravity, designers would be free of many of the constraints operating on Earth-bound computers.

    Laptops? I would have imagined thinks like that personal assistant floating ball that Slashdot said NASA found in Star Wars.

    Imagine computers around you, portables, projection screens, holograms, keyboards on your trousers, shaped as a ball, a tube, wahtever, but no laptops.

  • Depends a lot on the design of the mouse.

    Some have lots of room within the ball compartment, so if gravity isn't pulling the ball to the hole, the ball falls (or floats) away. Other designs have a tight ball compartment, so they're not affected.

    (Hope this message isn't filtered as pr0n, with all this talk of tight balls)

    Where do you get this idea?

    The Offical findings [nasa.gov] include

    • No single ignition source of the fire was conclusively identified.
    • The Command Module contained many types and classes of combustible material in areas contiguous to possible ignition sources.
    • Coolant leakage at solder joints has been a chronic problem.
    • The coolant is both corrosive and combustible.
    • Deficiencies in design, manufacture, installation, rework and quality control existed in the electrical wiring.
    • These deficiencies created an unnecessarily hazardous condition and their continuation would imperil any future Apollo operations.
    • The Command Module Environmental Control System design provides a pure oxygen atmosphere.
    • This atmosphere presents severe fire hazards if the amount and location of combustibles in the Command Module are not restricted and controlled.

    The only mention I can find of velcro in the whole report is when velcro straps burn, but this is some 15 seconds after the start of the fire, so they're obviously not the cause.
