  Cold equations

Jeffery Bell exposes the cold equations of spaceflight - bashing most attempts at creating reusable rockets. I largely agree with him - what we need to return to the moon closely resembles a lighter Saturn V... unless we get the fuel for the return trip - and the boost to the moon/mars from elsewhere.

Not that that's stopping spaceX from announcing the falcon-9 - a vehicle capable of lofting 55000 lbs to LEO. Theoretically. For only 35 million dollars a shot - a pittance, compared to any other launcher currently in existence. They have a contract to deliver from Bigelow aerospace in 2008.

Their falcon-1 is yet to fly - but it's supposed to fly soon. At one level I'm filled with hope for the space program - at another - doubt. Only time will tell.

Hello fellow fisherman,

Did you know that 16% of the U.S. population goes fishing at least 16 days a year?

Did you also know that over 75% of the nations fishermen do not fish during "prime time"; fish feeding hours?

Those precious few moments before twilight can be absolutely magical. Even up until 11pm at night, the largest predators of any species feed ravenously.

Don't believe me? Check out Daniel Eggertsen's story, and a picture of a couple of his catches here : "Evening Secrets plus more"

I want you to do me a favor and try it out so I can see what you think of it, and if it works for you as well as it did for me.

You will be one of the first to try it out.

Gone Fishin',

Neil
