    The moon landings were about beating the Russians into and for dominance of space and the moon.

    So, a failure then. The Russians still have pretty much as much space activity as the USA. Russians plus ESA or the Chinese would out-activity the USA. And the Chinese and Indians are coming too.

    That moon is in a considerably different situation - it is in orbit around something with a coating of liquid (that's Earth ; I'm depressingly sure that some Slashdotters will need telling that) which allows much more tidal coupling of the two bodies. So the rotational angular momentum of Earth is being transferred to the Moon, slowly. About 2cm/year slowly.

    That might have happened between these two - but only during a relatively small time slot when the decay of short-lived isotopes might have made the bodies pliable. The absence (or very low number, per imagery downloaded to date) of impact craters on either body means that impact heating could not be significant.

    (The low crater counts were predicted. I was reading papers discussing that a week before closest approach.)

    Yeah, but is that because the cash drawers won't open and close, or is it because the cashiers can't add up a string of numbers as fast as they're read out, and work out the appropriate change from a three dollar bill.

    I thought the purpose of organic produce is that it won't harm the environment like mass produce requires.

    It isn't that well thought out. What "organic" means is that the production methods follow the rules written by the Soil Association (in the UK ; I assume there is a comparable body in the USA). Nothing less, and nothing more. What "organic" is marketed as varies according to what you are selling. So, if you're selling grains, then you say that the purpose of "organic" is to promote the use of less (or different) fertilizer, but you don't mention that permitted fertilizers include half-rotten pig shit and exclude shit-free chemicals manufactured from thin air and pure water. If you're selling organic lamb, you market it on claims that "organic" means "better tasting and healthier" to distract people from thinking that it means a lamb adolescent being hung up by hooks through it's ankles and then having it's throat cut. Because that might upset the eaters. You may notice that there is no connection between what the term means, and it's advertising insinuation. Did you actually expect anything different.

    But with the increasing body count from the followers of a certain religion you can't be that way any more.

    That'd be Christianity, would it? Most American terrorism is from rabid redneck Christians attacking people who differ from them in skin-colour, religion, or which bits of their body they rub against other people for fun.

  8. Actually, traffic was fucked up because this guy was a pedestrian on a vehicle-only road - a "motorway" in EN_GB. It is an offence to be a pedestrian on these roads without authorisation (road workers) or good cause (your vehicle has broken down and you are walking from the breakdown to the nearest emergency phone). (Bicyclists and horse riders / horse-drawn vehicles are also banned.) So the police were doing an operation to detain a criminal and shut down the road for their (perceived) convenience or safety. I believe American police have comparable powers. You'll notice that I haven't mentioned the drone. I've given it all the importance it warrants.

    The data is international anyway. It's part of the international network for monitoring compliance with nuclear test ban treaties. So any one of those sites should be able to get you everything you need.

    I'd call that pretty effective self-promotion. A nice project too, I'll grant. But he's done a good job of turning this opportunity into a good CV for helping him in his job hunt. $5000 invested, and if it pays off in the next several years and he's kept the receipts, he should be able to put it against tax.

    When a satellite and it's primary are gravitationally (tidally) locked, the locked component rotates at the same period as the rotation of the secondary around the primary. That's the situation we have between Earth and Moon - the Moon goes around the Earth every 29.x days (x varies on which version of "around" you want) and the Moon rotates on it's axis every 29.x days (same caveat). It is also possible for the primary to become tidally locked to the secondary, which is the situation between Pluto and Charon.

    H2, He (miscible above 3.x K, IIRC), Ne. Nitrogen is close to it's triple point on Pluto, so it can slip in and out of fluidity.

  14. Wrong country. Or rather, wrong "hunting" technology. When "hunters" discourage birds from airfields, their technology is four thousand years or so old - the falcon. (Hawks, or other birds also work.) Birds have been ignoring the discharge of shotgun cartridges in fields for several generations of the birds. The ones who startle get less food and their chicks are fewer in number than the ones who don't startle. It is a good technique for wasting money on shotgun cartridges. If that is, for some reason, your aim in life.

  15. Does the airport have the authority to shoot down any drones that are endangering planes taking off or landing?

    The answer is irrelevant. The airport - which may well be owned by a foreign company - can have all the authority it wants, but it doesn't have any personnel with weapons.

    If you see someone carrying a gun at an airport, it is a policeman or a soldier. It is not an employee of the airport.

    Title - "Hubble PanCET: An extended upper atmosphere of neutral hydrogen around the warm Neptune GJ 3470 b"

    At https://arxiv.org/pdf/1812.051...

    What is the big interest? Well, mostly that the population of "hot Jupiters" seems to be bimodal (two types of highest frequencies, but intermediate and extreme systems are present). This planet lays near the edge of one of those lower frequency bands, and is losing in the order of 10,000 tonnes/second of hydrogen - which sounds a lot, but over it's 2 billion year lifetime (less than half that of the Earth) only amounts to between 4% and 35% of it's original mass.

    If there were other planets in it's system, that's really mess up their orbital stability, if they had any to start with (on the billion-year time scale). On the other hand, that gas takes a time to be driven out of the system, potentially providing a mechanism for "dynamic friction" to damp the instabilities produced.
