I still think $150 per kg to LEO is a goal we need to set for the best
price of orbital costs.

Well that explains why nobody wants to improve the space program,
3,500+ people would be out of work and the drop tank people out of a

Nope ... inertia is the same. Because F=MA you can in theory move any
object if that object moves very very slowly.
A guy working in a space suit does face some risk of injury, but not as
much as the movies and tv makes out. With pure O2 at 3 lbs pressure in
a space suit a complete loss of air is not fatal providing the person
can reach shelter with in two minutes ,from a rip or tear in the suit.
I do admit many things taken for granted - turning a wrench, boiling
water , having sex ; do change in space and that is the challenge of
Things are more expensive in space ( ignoring the cost of getting there)
because things have to be done by hand, something that the industrial
revolution has caused people to forget. Guy S may take 8 hours to
a prefrabicated wall in space, guy E 10 minutes using power tools and
assembly line fabrication. Why do I get the feeling that space access
will be run by big companies who's goal is profit, like the Company
for Coal mining?
