maybe they should build moon landers this shape :-)

That is indeed the example they mention in the paper https://arxiv.org/abs/2506.19244.

They could do that, but a regular gomboc would be totally fine. There are no rules for spaceships that their corners cannot be rounded.

Maybe exoskeletons for turtles could be more useful. Turtles with their short legs, require the bottom of their shell to be totally flat, and a gomboc has no flat surface. Vehicles that drive on slopes could benefit from that as well.

Per the article that's what they're working on, but it probably won't be based on tetrahedrons considering the density distribution. Might have curved surfaces.

"If tipped, will self-right" sounds like exactly the kind of feature you'd want on the Moon

Or aeroplanes. Not sure where you put the wings.

Why restrict yourself to the Moon?

They will only need to ensure that the pointy end does not penetrate the soft surface too much on decent, becoming an eternal pole.

Just need to apply this to a drone, and we would be one step closer to skynet. The props could retract into the body when it detects a collision or a fall.
