...to put a dot on the moon? :D
|
erm... VERY:D

You wouldn't be able to see the laser, but if you got it on the right point:
Lasers can be shone onto the Moon because the NASA astronauts that landed there took mirrors with them. These mirrors reflect the laser light back to the Earth. Lasers are used to measure the distance to the Moon very accurately. If the time taken for the light from the laser to go to the Moon and back is carefully measured and the speed at which the light is travelling known, then the distance can be calculated. |

oh dear.
|
Awww bit more than the 75mw one I was after on ebay then :(
|
... it's a space station !!!!

Light travels at 300 000 000 m/s in a vacuum,ie:space. Your small laser might reach the moon, but you'd never know it w/o aHUGE telescope to see it with.

So should I spend my pennies on a medium sized laser and a heyowge telescope or a BFO laser?
I'm leaning towards the 2nd option at the moment... I've been looking at CO2 welding lasers .5KW should do it :p but apparently they emit light in the infra-red spectrum so I won't be able to see it :( might be hazardous to passing aircraft too :D I like the warning on this site http://www.altair.org/CO2laser.htm ! ! DANGER ! ! Do Not Look Into Laser With Remaining Eye |
Are we talking about a "laser"....
lmfao |
Yeh--Light Amplification by Strategic Emission of Radiation
L A S E R |
Light Amplification by Stimulated Emission of Radiation actually :p
I'm an expert now! |
|
Your first step would be to get a car number plate onto the moon. My laser pointer (Class 3a) picks 'em up at incredible distances!!!
As for "www.space.com" - popup hell!! :eek: [img]images/smilies/mad.gif[/img] mb |
Get a key ring laser and shine it through tha bottom of a milk bottle. This will magnify the laser and it will be mega. Make sure you dont shine it at any Astronauts eyes as this could blind them.
