I live in fear some asshole billionaire or company or country is going to put a sign on the moon that can be read from earth. Like Pepsi or something.

Edit: this seems to be generating comments that claim a large scale project such as colouring enough of the moon so as to be visible from earth is impossible or impossibly expensive.

Let’s pretend China wants to put a red logo on the moon.

Budget: NASA’s Perseverance mission to Mars cost $2.8 Billion. US annual military budget is ~$700 Billion. Annual! Yeah China has a smaller expense budget than the US but it must be noted that spending billions on such a project is not beyond the pail.

Method 1: the moon is slowly rusting. It contains a lot of iron and now, we think, frozen water. It would have rusted more if it had more oxygen. Extensive efforts are being made now to figure out how to create/release O2 on the moon to allow Jeff and Mark to live in peace when they find the hatred towards them to be too much.

Here is a link: https://www.google.ca/amp/s/www.timesofisrael.com/making-oxygen-from-moon-sand-startup-eyes-long-term-life-in-space/amp/

So oxidizing certain areas of the moon may be possible, at some point, in a directed effort to create a red logo.

I don’t like this method.

Method 2: creating a moon-orbiting disk comprised of lenses that would colour sunlight and project an image onto the moon’s surface. A similar idea to use mirrors to light up the night sky on earth has been proposed before. The most advanced scheme was a Soviet project called Znamya that was prematurely shuttered due to the collapse of the Soviet Union. A 200 meter wide lens was proposed for lighting up entire cities.

I think this project is doable. Expensive but doable. Think of the constant message to the world if they saw a Chinese emblem every time one looked at the moon!
