Hi,
I don't know if it's correct to place a thread like this on Ice In Space. But Drake's equation has always fashinated me. Playing aroung with different parameters and see what I get in the end. Do we have any neighbours ?
I had it as an Excel sheet earlier, now I have done a Drake's Equation calculator on my homepage.
Here it is:

It's the basic version. Have fun time testing !
