We are not selfish we just step over anything and do whatever it takes to get things done. And ya why would we not create something that might make it easer to go into space to do different types of repairs on different satellites.

Ya true...I wonder how much this thing is going to cost..sometimes I sit back and think where else this money could be going...but then again they may discover something super important that may benefit the world...I would rather see millions of dollars go into science and technology than to see a hockey, baseball, or football player get paid that much.
