Is moonvertising feasible?

+0
−0

As the legend goes, Coca-Cola was planning on shooting lasers at the moon to project their logo. Unfortunately, the FFA said no (they didn't want planes to be blinded). I haven't been able to confirm or deny this specific legend.

My question though, is it feasible? Could you project a logo on the moon such that you can see it on the ground? How much would such a project cost?

We'll say that 10% of the moon's surface should have the logo, and be fairly visible from earth. Color is unimportant.

Is moonvertising feasible?

Note: I am not talking about etching anything in the moon. The moonvertising would only be active why the lasers are shining. It's basically a high power projector.

Note: Moonvertising during new or crescent moon is allowed.

Note: Here is a clickable picture of two dots being projected on the moon.

Painting the moon with lasers wouldn't work, as the light of the sun would overwhelm just about anything, the power needed would be prohibitive, it would only work for short amounts of time while the moon is in the sky while it's dark and in range of the laser, etc.

They'd be better off putting up a space billboard, as it would be cheaper, work during the day, and depending on what orbit it is in you could get global visibility. Everyone would hate it, but there's no such thing as bad publicity!
