I think NASA in geting to much into the Comercalization of Space. Leave comercial satalites to the private sector and concentrate on space exploration. Stop focusing on earth orbit, we need to send an interstellar space probe, send a probe to Pluto, go to Mars, etc. Why is NASA stuck in earth orbit? we sould be colonizing the moon by now if it wasn't for the freaking buget cuts in the 80's.
Basically it is far more cost effective to observe from orbit. Realistically the only advantage sending probes has is for real close stuff within the solar system. For other star systems, completely useless. Besides we have reached a point where we can discern planets around other stars (albeit very large planets). And I am sure it will improve over time.
