I'm offended that you're lumping me in with these guys.

The engineering necessary to build and fly a LEO fuel depot really isn't
beyond the current state of the art.

No it's not. It's just that the idea doesn't make any sense, the same way
their ideas don't make any sense.
And you are just as fixated on this idea as they are on theirs.

It doesn't make sense given NASA's current architecture where everything is
disposable, but the SRB's and maybe the Orion reentry vehicle.

At some point though, disposable launch vehicles and disposable spacecraft
aren't going to make sense anymore. In order to reuse some of these
expensive pieces of hardware, you're going to need to refuel them since
bringing them back down Earth's gravity well makes even less sense than
refueling them.

Have you even read the testbed proposals from the Centaur guys? Here's
one:

Google "Centaur cryogenic testbed" and you'll find quite a bit of info on
the topic. Again, these proposals are from some of the world's leading
experts in cryogenic fluids in microgravity.


Again, the technology isn't the problem... it's the whole orbiting fuel
depot _concept_ that doesn't make any sense.
I'm going to killfile you now, as I'm getting sick and tired of reading
about this thing.

This group is dying anyway, so it's not surprising that I'm the only one
here who thinks that LEO fuel depots will be necessary for Mars missions.
NSF is a hell of a lot more active than this newsgroup. :-(

To quote Eric Cartman, "Screw you guys, I'm going home".

That has to be one of the oddest correlations I've ever seen.

Oh sure, there's a lot more traffic there... But not a whole lot of
content, and a nasty shedload of groupthink and cluelessness.

You just wait; I'll bet he can do better than that. :-)
