[amsat-bb] ISS future?

[Randy]

"""  We have 5-6 years left of ISS.  We need to make the best of what little
time we have left.  Everyone needs to work harder, better and faster.  I
would hate to see those remaining 11 unused antennas go to waste when ISS
burns up."""

Ok , label me ignorant .. But is it that difficult to boost its orbit? I
guess I need a techie explaination .. 
Heck .. If its going to just burn up .. Then just before it gets to the
point off no return, then take those 
Huge solar panels to the moon .. LOL  or take some of the modules to the
moon .. 

Whats going to replace the space station? The lunar base?

Anyways... Someone explain to me please lol
