  1. Re:Minor explanation on Huygens Probe Lands on Titan · · Score: 4, Insightful

    The designers of these probes and landers are really outdoing themselves. Look at the two landers on Mars that are WELL past their guaranteed time. I wonder if they purposely make them work well beyond their guaranteed time just to 'show off' or something.

    Everything has failsafes. For instance, suppose you're powering down the runway in a Boeing 777, just about fast enough to take off, and the nose of the plane starts to lift.

    Suddenly, the right engine fails. There isn't enough runway left for the plane to safely slow down and stop. Oh god, you're going to die, right?

    Nope, the plane is built to be able to take off even if an engine fails. So under normal circumstances, the plane actually has far more power than it needs, because it's designed to continue to function safely even when severely compromised. The designers aren't "showing off", they're building in intelligent failsafes.

    It's the same deal with spaceships, only far moreso because it's been years since the probe has had a mechanic available to look at it. It has to work, even millions of miles away from home in incredibly hostile conditions and years since its last tune up.

    So the designers build redundancy and failsafes into everything. The spacecraft should be able to handle the failure of a number of systems and be able to keep right on ticking, although of course it may suffer reduced capability as a result.

    In the case of Huygens, it has more batteries than it needed to carry out its mission. Batteries can fail, or not perform as efficiently as they were expected to. So you slap an extra one in, just in case. Apparently the batteries all performed well, so the probe ended up surviving significantly longer than it was "supposed to".

    Battery life. The probe, if I remember correctly, has five LiSO2 batteries that are its sole power source (along with some 1W radioactive heaters simply to maintain its temperature).

    The trip to Titan took three weeks, and there was at least some electrical activity on the probe that whole time (I know it had a timer set to "wake it up" for the descent). Then the probe kicked into high gear for the descent, running all its systems off the batteries.

    It was expected to go dead sooner than it did, but the lost data probably wouldn't have told us much -- after it had been sitting on the surface for a few minutes, it had probably already reported everything interesting.

    Radiation has nothing to do with volcanic activity. The heat inside the planet is not caused by a nuclear reaction.

    I suggest you go read up on Lord Kelvin and his attempts to prove that the Earth couldn't possibly be millions of years old. He argued, quite convincingly at the time, that when you accounted for all known incoming and outgoing heat, the earth couldn't be more than about 10,000 years old or it would have frozen solid. And it is true that the earth is slowly cooling off, as the Sun doesn't provide enough warmth to keep our temperature this high.

    Lord Kelvin was almost right. If there were no variables other than those he knew of, the earth would indeed have frozen solid in 10,000 years or so. But he performed those calculations before the discovery of a process called 'radioactivity', by which the nuclear decay of various substances produces very substantial amounts of heat. And fortunately the Earth has an absolutely incredible amount of radioactive material, the slow decay of which keeps us nice and toasty.

    So, A) vulcanism is very much related to radioactivity. The earth would have frozen solid by now otherwise, and there would be no volcanoes. And B) while you're correct that the heat isn't caused by a nuclear reaction (rather decay), nobody said it was. The parent was talking about exactly what I explained here.

Writing a real application, like a word processor or a web browser, is difficult no matter what language you do it in -- and I would argue that the difficulty doesn't vary much between languages. In fact, I would further argue that many of these research languages, while making toy problems easier, would actually make "real" programming substiantally harder, because the semantics of the language are not as formalized and thus more difficult to remember and deal with.

    I'm certainly not opposed to advances in language theory and design -- our modern-day large applications would be essentially impossible to write if all we had to work with was machine language. But to be a major advance, a new language should focus on making real problems easier for real programmers, not making toy problems easier for non-programmers.
