Discovery gets a spatial treatment ;)

NASA's Discovery today got a protruding filler removed by a space walking astronaut. Pretty cool pictures at NASA.
Here's what I get very frustrated about.... its great that these guys are able to do emergency repair work like this, but is this what the time in space should be spent on ? NASA needs more funding people... fund them so that they can build the next generation of the space shuttle, something that does not have to rely on stone age era tiles(brittle ones at that) to provide protection against excessive heat during re-entry.
What if the entire world put aside its military spending for one whole year ? We could end poverty everywhere and build massive space stations ... can we not ? Humanity...let us evolve ...TOGETHER.
