"Tarver Engineering"
GAO has reported that the number of astronauts is not supportable by the
flight schedule of NASA. Additionally, GAO found that NASA is
inapropriately filling engineering slots with astronauts.
I think robots have to be developed to enable the experiments in LEO and
no
human cargo is necessary.

That's been the case from the beginning! That is not only the case for
Low Earth Orbit robotics but also for Planetary exploration. Look at the
success of the Mars Pathfinder mission. Too bad they sometimes screw up and
mix calculations because of metric and imperial measure. Stupid mistakes
like that cost big bucks. Another mistake was not comparing the two primary
mirrors built for the Hubble. They selected the "bad" one for launch.
Cutting costs and cancelling testing, resulted in a lot of dollars being
wasted. Was that NASA's fault or govenment funding cutbacks??? Manned
exploration is important but not necessary in some cases. Columbus would
still be sticking notes in bottles had he not sailed west. There is a case
for both to be made.
