Pretty neat how any petal down works. Just unfold, and it self rights.

But it's only upright when the base petal is on the ground. It keeps flipping from petal to petal until the base is on the ground. It's also pretty amazing how this bigger vehicle folds itself up into a volume the same size as the smaller Sojurner. That's because it had to fit inside the same airbag system and launch fairing.

I didn't realize they were the same airframe/air bag system. Makes sense though.
