It's a weird tetrahedron.
The geometry is now confirmed.
Japan especially has suffered at least two
recent instances where landing was achieved,
only for the lander to tip over on its head,
mostly useless. Wider conventional legs MAY
have helped ... but wider=bigger=heavier.
This new shape - mostly achievable with 'legs' -
seems to be the easy fix. Your probe will always
land upright, uneven ground or not.
