QUOTE (hendric @ Sep 18 2005, 08:27 AM) Don't hard drives require air to levititate the heads off the platters? What happens in space? Did those previous experiments seal the HD's in their own atmo? HDUs certainly used to have so-called 'flying heads' which 'flew' just above the platter surface, that's true. I was recently told that there are other forces also involved, but in fact that wouldn't matter - the HDUs wouldn't be data storage devices, but momentum storage devices - you'd probably strip out the head components in the build process. I don't know what, if any, form of lubrication is used in HDUs, so outgassing/drying might be a problem in an airless environment. I'd expect flash memory to be the medium of choice for data storage. -------------------- Remember: Time Flies like the wind - but Fruit Flies like bananas!

As promised, here's an illustration of a manual launch option for my late 1970s BOBSAT proposal - the battery pack is shown in the act of extending from the shell.

Let's go one step smaller - how about nanoprobes? A fleet of nanotechnology probes exploring the Sol system. If we lost a few of those, it would be unfortunate but not an end to the mission.
How close are we to developing such machines for space exploration? -------------------- "After having some business dealings with men, I am occasionally chagrined,
and feel as if I had done some wrong, and it is hard to forget the ugly circumstance. I see that such intercourse long continued would make one thoroughly prosaic, hard, and coarse. But the longest intercourse with Nature, though in her rudest moods, does not thus harden and make coarse. A hard, sensible man whom we liken to a rock is indeed much harder than a rock. From hard, coarse, insensible men with whom I have no sympathy, I go to commune with the rocks, whose hearts are comparatively soft." - Henry David Thoreau, November 15, 1853 |

I got all excited and started to build a card model of a cubesat

I think I'll finish mine tonight...I'm cheating and using double sided tape...but then I'm taking the time to put a bit of card on the back of the main panels for a bit of added strenth.
Not sure about the antenna component though - it should be really fine wire, but then the cat would take her eye out on that so I'll just go with what's printed There's a model of the Japanese cute-sat somewhere, but it's onle 1/2 scale and isnt as good as that one Doug |

You've got a laminator - that's cheating
I totally screwed it up last night - trying to make a cube, not noticing that the corners are turned inside out (you'll know what I mean) I'm almost done Doug |

Damnit - if I'd have thought of this first
http://www.milliondollarhomepage.com I'd be building a real one for UMSF Doug |

They have proposed a Cubesat Moon lander also, 1 kg and that includes a miniature rover with a camera! *Blink*
