    Isn't the largest rocket they currently have only capable of putting a satelite into a Geostationary orbit? Like, wouldn't this take the full Falcon Heavy to actually do?

    However, if this does actually happen? I will fucking be there for that launch.

    as scot manley pointed out, it takes less delta-v to do what they are suggesting than to get into geostationary orbit

    What does "intercept" mean? I assume dot for the planet itself is landing, and orbit is self explanatory.

    A flyby basically. Getting to the point where you could begin to orbit it

    edit: basically each segment is a burn (or atmospheric capture)

    Say you go to mars:
    Burn #1 puts you in LEO
    Burn #2 puts you leaving Earth
    Burn #3 adjusts your trajectory to hit Mars at some point
    Burn #4 establishes orbit when you get there
    Burn #5 lets you land

    It's basically the series of standard transfer orbits

    In reality Burns 2 & 3 would be combined (possibly 1 as well depending) and 4 & 5 would likely be combined and partially helped by the atmosphere

    It doesn't have a set meaning apparently but would generally be the point where gravity of the object generally dominates.

    Yeah, I think it just means "move to the relevant position around/on target body". To where you can say you're near it, I guess.

    In kerbal space (where that map originates) it's the point a which the game starts tracking the objects mechanics as a two body problem with respect to that body.

    Although that is based on a real approximation since patched conics are a solution that's actually used for orbital manoeuvers to allow you simplify a problem to a 2-body solution + correction factors.

    Reusing (word for word) an introduction or abstract from one of your own papers in a grant, research summary, or a fellowship application is (aside from being a bad idea) plagiarism, right? That's what I was taught.

    That said, it is exceedingly annoying to write a new intro every time.

    Don't know about academically, but depending who owns the IP you can totally get in legal trouble for self plagiarism. I could see it being a potential issue best avoided.

    Yep. I personally think the idea of self-plagiarism is pretty ridiculous, but at least in the case of papers, the publisher generally owns the copyright so there's that. Where it drives me crazy is methods sections, because I feel like they should be excluded from checking because if I did the same procedure/analysis as in a previous study, I want to describe it the same way, but I can't.

    I was reading more articles on this last night. There seems to be some consensus that methods sections are at least partially exempt. Or you can just cite it and be done. The issue is more with paper text. I've had like three people give me things to review, and then all of a sudden there's a section written in a totally different voice, and I start googling, then lo and behold its from their last paper.

    So I thought this was pretty amazing. Scientists train bumblebees to move cotton balls to a goal in order to receive a reward. These bumblebees then go on to teach the skill to other bumblebees.
    Perry and colleagues built a platform with a porous ball sitting at the center of it. If a bee went up to the ball, it would find that it could access a reward, sugar water.

    One by one, bumblebees walked onto the platform, explored a bit, and then slurped up the sugar water in the middle.

    "Essentially, the first experiment was: Can bees learn to roll a ball?" says Perry.

    Then, the researchers moved the ball to the edge of the platform.

    "The bees came out, looked at the center, didn't have reward. They went to the ball, didn't have reward. They had to figure out that they needed to move the ball from the edge to the center, and then they'd get reward," says Perry.

    The ball was a token, like the dollar bill you'd put in a vending machine. The sugar water was like a can of soda that could only be unlocked using the token.

    If a bee couldn't figure out how to get the reward, a researcher would demonstrate using a puppet — a plastic bee on the end of a stick — to scoot the ball from the edge of the platform to the center.

    "Bees that saw this demonstration learned very quickly how to solve the task. They started rolling the ball into the center; they got better over time," says Perry.

    In a second experiment, the researchers found that bees that were able to watch a live bee do the trick first learned even faster. Some even found ways to get the sugar water more quickly by choosing a shorter route.

    "It wasn't monkey see, monkey do. They improved on the strategy that they saw," says Perry. "This all shows an unprecedented level of cognitive flexibility, especially for a miniature brain."

    Here's a nice short video of the experiment:

    https://www.youtube.com/watch?v=exsrX6qsKkA

    This is so far beyond my expectations of insect cognitive capabilities that I can't even.

    It's pretty cool, though honestly, it makes sense that bees could learn from watching other bees. They already have dance-language, so obtaining information from others is built in.

    I'm imagining awesome soccer matches between two nests of bumblebees trained to take the ball to different goals.

    There's a danger that such matches would turn violent though. I know wasps and many ants will fight other nests of the same species for resources, but a quick googling didn't turn up anything about bumblebees.
