Project on to the moon!

[Stevenj214]

How feasible would it be to project images onto the surface of the moon?!

[Famous Graham]

Piece of piss.

You just need a VERY big, and focused, projector.

Perfectly feasible, as far as the physics is concerned.

As for the reality...erm...we're not quite there yet

I'd say impossible with a light projector.

Big fk off laser though and you could reach it with the right lenses.

Big version of this, for example.

I sometimes struggle to get a presentation to focus on a wall 7 feet away never mind a quarter of a million miles away.

Nice concept though.

To what end and see it back here? They fire a laser at the moon and count a miniscule number of photons returned off the reflector. By the time the laser hits the moon it is several kilometers across. Probably nigh on impossible today.

Edit. Not forgetting that the regolith will scatter the light where there is no reflector.

More importantvis what would you want to project?
Didn't frankie Boyle say they should have saved the money from the olympics to write 'fk off Germany' across the moon?

I was thinking "Coca Cola", "Google", "Microsoft", etc. Mostly whoever will pay the big bucks!

you're not thinking the batman singnal are you? as per the 'ive got a new mahoosive torch' thread?

Is this Winkys latest idea to win the general election?

That and you'd need a good lead on when you start shining the light...
How long would it take to reach the moon, 30secs or so?

It's late and I can't be bothered to work it out... I know it's 6 mins for light to 'arrive' from the sun...


But as you say, in a purely physics-based way, not particularly difficult!

[GilbertGrape]

More feasible than landing a man up there.

I was sure it was 6 an' all!!

Just turn it up to 11.

Almost impossible. The moon reflects only about 12% of the light that hits it. Not to mention that its very, very, very, far away.

It's not that far!

We can see it

or "fk off Germany!"

I've done a cardboard cutout that says THE END OF THE WORLD IS NIGH...

But I can't get my little led torch to get it up yet...
