      Nah, have to be without equipment since 1998, and the whole “rocket snail” incident. Banned any support items after that

    Well since they can’t reach that speed without being in the air, technically they’re the fastest animals OFF Earth.

      Planets are typically understood to include the atmosphere.

      You wouldn’t look at Jupiter and say, “well it’s not really that big, there’s just a bunch of a clouds in the way,” right?

      So the peregrines are on Earth, but not on earth.

          The Juno mission says “probably, but whatever is going on is weird af” and the current explanations are way above my head.

          I think they still mostly assume there’s a rocky core, somewhere.

            I wonder what magnitude of pressure exists on the surface, if there is such thing. It must be molten from the extreme pressure and gravity. Right?

              Have you seen supercritical water and/or helium? The “surface” of Jupiter is probably supercritical hydrogen. I don’t know if there’s a sharp cutoff like Earth’s oceans or a gradual thickening, but it’s still only half the density of water. It’s possible to build a boat for that!

              However, the pressure would be around half a million bar, or 500 times the pressure of the deepest part of the ocean. This is also 5× the pressure used to make synthetic diamods too, and probably about the same temperature too. If the boat had any grease left outside, it would be diamond grease at this point.

              If you went further down to where the density increases to about the same as water at sea level, the pressure would quadruple to nearly the same as Earth’s core, and the temperature would be about the same too. At this pressure, there’s probably another indistinct boundary of metallic hydrogen, and if the boat has survived the ultra-high-pressure hydrogen embrittlement, the steel-liquifying temperatures, and diamond rain, this metallic hydrogen will almost certainly reduce it to a lump of novel metal hydrides.

    To be faaaair, the cheetah reaches 100+ km/h on it’s own merits, the dumb falcon just falls really fast

    If you drop a whale from space it will probably beat that speed record while falling, the falcon doesn’t get extra credit just because he can get up there and survive without help

    One of the craziest interactions I have seen was when a Peregrine Falcon attacked a Canada Goose in flight. We were watching the goose fly up canyon and the peregrine must have thought it was too close to its nest or something. Only time I’ve heard a goose make a sound like that!!
