Launching everything we need from Earth is too expensive.
True! And yet for 50 years, I could never help noticing, we have de-orbited everything we've sent up! It seems as though noone has given any thought to making things we spend $$$$$ billions and billions $$$$ putting up there so that it will be useful in the future.
It wasn't that long ago that they were talking about de-orbiting the ISS in 2016 !! Gosh, I wonder if there's anything long-lasting enough in the ISS that might be useful later. Gosh, maybe Henry Ford was ONTO something when he discovered standardization of parts. LEGO seems to have figured out how to make a whole lot of stuff work together. Maybe they could hire LEGO.
Huh. I wonder if a plan would be possible. If there were only a bunch of smart guys sitting around in fancy government buildings looking for something challenging to do something that lasts longer than the next election. Instead of looking for more ways to throw more money into the Right pockets.
