    Curious George

    The Cow Event

    I know just enough to take wild guesses, but not enough to identify why I'm wrong. If someone could point out where my guess falls apart (I'm loathe to call my spitballing a hypothesis) I'd appreciate it. If a star's orbit was deflected by another star such that it was within a blackhole's Rosche limit, would that explain the appearance of the gas cloud? The subsequent accretion disk could also explain the dramatic rise in luminosity. If a single star is insufficient for this amount of gas and luminosity, how likely would it be that multiple stars would suffer the same fate in such a short time span (my gut feeling is that this is so unlikely as to be almost impossible, but I don't know the numbers for it)? The article mentions that a blackhole of this size could not destroy a larger star from tidal forces, but if a larger star passed so close to the black hole that a portion of it passed within the Schwarschild radius (or close enough that mass was lost) could we see a larger star get disintegrated? This would require such precision that it seems incredibly unlikely, but, again, I don't have any of the numbers on it. The second explanation provided by the article, that a supernova was not obscured by debris, seems more probable than any of my wild imaginings.

    They should protect the nozzles with water-proof caps instead of the legs. Also, drink water is less agressive than sea water. You quoted a statement about reusing fairings that went for a swim. The first stage's reusability is in no way dictated by the landing conditions after which a fairing may be reused.

    BFR doesn't move itself into orbit around the Earth. It moves Earth into orbit around the BFR. To land it puts Earth back where it's supposed to be. Calling it now. (Top that for insane speculation!)

    "Look! You can see the two things both firing their engines!" It's Scott Manley official: stages are henceforth to be referred to as things. Congratulations to SpaceX on successfully shooting their smaller thing into space and successfully recovering their larger thing. I bet their engineers can't wait to get their hands all over it.

    Most likely landing pads one through four were planned before the decision was made to cancel landing pad three. Renaming pad four after cancelling pad three would be a waste of time and manpower, plus a possible source of confusion and inefficiency given that landing pad three meant something entirely different in the recent past. It's easier to build landing pad four to completion and then rename it than it would be while it is still an active project, but even then it would serve little purpose. If they were sequential, such as train stations along a single line, then it would make more sense to rename them, but that's not the case. All three pads are independent and the number is just a title for them.
  6. I suspect that increased drag at its current altitude would overcome any potential gains from a solar sail. Might work if you raise its orbit before deploying it, though. Edit: Wikipedia (yeah, I know) says that drag and solar pressure are equivalent at roughly 800km, so we'll need to boost the station higher than that for it to work.

    So I decided to make a solar system...

    Looks interesting. How much can be tweaked between simulations? Can a user start with more or less asteroids, change the range of masses they start with, their initial velocity, etc? Does it give you the option to automatically save a screenshot periodically (say, every year) so you can run a more populated simulation over several days, then go back and watch it? In any case it looks like the sort of thing I'd spend a few hours playing around with, then leave running overnight to see how much it changes.

    Definitely Penguin, if only so that we can get headlines like "astronauts ride four penguins to Mars."

    The solution is surprisingly easy. Information, no matter how it is stored, is likely to degrade, be misunderstood, or considered a hoax. I have something far simpler in mind that, so far as I can tell, does not violate any of the initial assumptions.
  10. "It's actually a very tricky question," says Dr Simon O'Toole from the Australian Astronomical Observatory. "A lot of people think it's just taking the highest and lowest points on the planet and finding the average, but it's not that simple. Because there's no sea level on Mars any more, zero altitude is defined as a specific atmospheric pressure of 610.5 Pascals, about six millibars. This value was chosen because it's the triple point of water on Mars, where it can exist as gas, liquid or solid." Courtesy of ABC News. I'm not sure whether it's correct or not, but it sounds plausible and I'd personally believe it unless corrected by an expert.
  11. If you look at the painting closely, I think you'll find that people are leaving the ferry. They probably got tired of waiting or suddenly discovered an inexplicable hatred towards watercraft.

    And here I thought pornography was against forum rules (not that I'm complaining).

    It's interesting to look back at previous flights. I didn't realize that they hadn't failed a mission in 15 months (17 consecutive successes), or that it's been 18 months since they last failed to land a booster, or that a quarter of this year's flights were on reused boosters.

    If I were a whale and got woken up like that, I might just smash the boat out of spite. Keeping quiet and hoping for the best might be safer.
