Re: NASA's "New Space Vision"

[John Jacobus <crispy_bird@YAHOO.COM>]

I find it interesting that there is no mentioning of a

new, heavy lifting rocket.  If I remember correctly

ex-V.P. Dan Quayl was incharge of a program to look at

this question.  (I think it was to keep him out of

trouble.)  In order to preform all of this "visionary"

things, will the present rocket systems, minus the

space shuttle be able to support the program?  



If you remember the Apollo missions, the Saturn V was

a massive machine, producing 7.5 million pounds of

thrust. http://www.apollosaturn.com/saturnv.htm



The space shuttle only delivers 5.8 million pounds of

thrust

I think I will need more that PR slide shows and

graphs to be convinced this program or "vision" will

go forward.
