I've been thinking about it, and it makes sense that these shuttles have to eventually be retired.
What I do not understand is why we are letting them just kinda fall back to Earth. I mean, would it be that difficult to give a satellite an engine and just fire it at the sun when it's old or something? I mean seriously, why did nobody think of this stuff? We are smart to build a 3500lb telescope that enables to see over 102 million lightyears away, but we can't figure out that if we throw a giant freaking rock in the air it's going to eventually come back down? WTF.

---- Titanium melts at temperatures close to the melting point of steel, you probably meant tungsten ( wolfram) which has the highest melting point of all metals.
