  2. Re:UTC on Software Bug Halts F-22 Flight · · Score: 1

    The reason the international dateline is spurious, in this case, is because I highly doubt there was an onboard time adjust. It was more likely an error in the navigation computer which didn't include an exception for going from 179 59'59.99" W to 180, and then to 179 59'59.99" E.

    To further back your suspicion, note that the date line isn't a straight line on the globe. It zigs and zags around various continents. In certain places it would be off the 180 deg longitude by a fair bit, which , while not particularly hard to code in, seems unlikely. So I vote for the W/E wraparound issue as well.

    Never mind - from a bit of online searching of some old archives, it would appear that Hubble's limit of focus is about 10000km -> infinity without adjustment. The range of adjustment needed to make in-focus observations of the ground is pretty small however (12mm or so), so it's quite possible that it could be done.

    But why you would do that when there are no doubt perfectly good spysats out there with better resolution, I don't know.

    The optics on Spitzer, like Hubble, aren't focused that close.

    Isn't there a point where the depth-of-field and resolving power sort of meet?
    That is, something at 10m and something at 10km are both pretty much at the same focus for my 38mm camera lens if I have a reasonable aperture. Setting it down to f/16, I can get pretty sharp shots from about 1m to infinity.

    For Hubble/Spitzer however, the difference between something 20m away and 100km away is (probably!) quite obvious, but the difference between 100km and 100ly would be pretty minimal, no?

    No. Lead-Acid batteries do not last forever.

    If you use 100% of their capacity, life is about 300-500 cycles.

    So you buy the biggest battery bank you can afford, and then draw the least amount of power possible. This gets expensive rather quickly, so you have to try and find a sweet spot.

    There are alternative battery technologies - Nickel-Iron are pretty much indestructible and generally last indefinitely, but they are terribly inefficient compared to Lead-acid - 65% compared to 95%. When you're powering a system from terribly expensive solar cells, inefficiency in storage is not good.
