    I know it’s just a webcomic but the KSP player in me hates how the engine bell sticks down past the landing legs

      It’s an engine skirt. It lets the lander move around on the surface at low thrust. Think hovercraft.

      To be fair it’s also blowing a sandcastle over on the moon. Where there’s no atmosphere…

        I think expanding exhaust gasses from the engine plume dissipating against the surface could do that if the castle was close enough. But then again, I’m not a physicist, just a KSP player

    The first time somebody builds a sandcastle on the moon out of regolith just for fun will be a historic moment for all of humanity.

      Well if we’re going to nitpick: It probably isn’t possible to build a sand castle on the moon without some special tools. Everyone who’s ever made a sand castle on the beach knows you need some water in the sand to make anything. Otherwise it’s just a pile of sand and won’t hold any shape at all. Now the dust on the moon is a combination of bigger and very small particles, so it kinda acts like flower on a small scale, thus footprints are visible. But I don’t think you could form any large structure, anything above a centimeter or so would collapse into a pile.

      With some special tools you could put the moondust in a mold and apply pressure, that way it would maybe hold it’s shape. But it would be a big challenge.

        On the other hand, the combination of microgravity, no wind, and more jagged sand particles might lead to better cohesion

      I can see that happening. It’ll be like watching a blacksmith bang on some hot metal at a renaissance fair.

        I’m just wondering who has the time to watch somebody draw a comic online. It must be like watching paint dry

          Not true! Paint dries very efficiently and consistently gets the job done, an expert in its field. Meanwhile I get easily distracted and make the process take a whole lot longer than it needs to.
