a

inflation
of airbags. As it rolls across the terrain it takes pics. This
could be very low mass.

Land, capable of moving and taking pictures on the surface of the
Moon over some period of time greater than a few milliseconds. You
ideas might work.

What would an Open Source Lunar Project look like?

Forget the airbage, too complicated. Instead simply use a solid
rocket that fires a few secs before impact to slow her down. Then,
off pops the payload that free falls to lunar surface. It is
basically a foam ball with a robust ccd camera imbedded in the foam.
It impacts which activates the camera that takes pics as it bounces
across the terrain. After it stops rolling, camera continues till
batteries die. I'd say, maybe 5 kg for the payload.

What are you going to use for a transmitter? Most spacecraft that
communicate with Earth from that kind of distance use a directional
antenna of some kind. If you're not going to have a mechanism for
aiming the antenna then you're going to have to increase the power
level accordingly.
