You know, people like you succeeded in getting everyone to wait after Apollo in the 1970s and very little was done.

That great space infrastructure we were supposed to have by 1985 never materialized. All we got was a space shuttle.

So your argument fails, sorry.
Actually seeing as my reaction is based on cold hard logic, realistic expectaions and a sound plan and yours is based on what is a currently pipe dream of instetller travel I think yours is the knee jerk reactionedit on 19-12-2013 by crazyewok because: (no reason given)

People like me? Dont you DARE put words and opinions into MY mouth, DONT YOU DARE!
I would have been 10000000% behind continueing the apollo program up to a moon base.
Hell I would have gone staight to orion project and we would have colonies on the moon of satern by now.
People like ME would have got you far further than the crap we have now.

Yup another white elefant and useless piece of crap.

I'm sorry, but that is extremely ignorant to say.
Depends what your prioritys are doesnt it?
If you want to look at pretty star then fine great.
If you have the opinion like me were I want to see humans move out into the solar system and exploit it resources then no its not much good.
Building Star Catalogs for Spacecraft Applications (Leonard J. Berg, Boeing)
Release of the Hipparcos and Tycho-2 star catalogs represented a huge step forward for the spacecraft application engineer. However, difficulties still remain when using these and other references to create star catalogs used to design, simulate, initialize, calibrate, and maintain spacecraft attitude determination processes. This presentation will outline the basic methods used to develop spacecraft application catalogs and help focus attention on the potential for improvement in resources used to support this effort.

Space SCIENCE as opposed to space TRAVEL.

Well a orbital shipyard would be a start like what russia have planned.
Earth to LEO orbit have little use beyond shuttles.
Orion project from the 60's would put us far ahead, though that would cost $12 billion from what was calculated.
Skylon that britan is developing would be a HUGE step forward. Plus germany had some good plans on the drawing board for mass produce rockets that could reduce the cost of launchs by a big factor.
So plenty of things to be done. Some big yes, others quite realistic like Skylon.

Then reality kicked in that there would be NO SHIPS. Cause there was NO MONEY or POLITICAL WILL to build them

Once you are to LEO you are halfway to anywhere in the solar system. This is an often used quote because most of the energy to launch missions is getting out of our Earth's gravity well.
JadeStar
And violated the UN Outer Space Treaty of 1967, the Nuclear Test Ban Treaty, SALT 1 and SALT 2.
Orion wasn't built for POLITICAL reasons as much as for financial ones.
JadeStar
You still have never answered the key question with regards of building space infrastructure: How do you change the political environment to one which wants to do these things?
Which is another "inefficient chemical rocket" but with wings..woooooooo hoooo!

Sorry we put a space station in orbit with it. We put a man on the moon without it
Im sure we could go to mars without it.
Unless something has a dircet purpose in :
Putting a shipyard in orbit
A colony on the moon
A colony on mars
I dont see it as anymore than a luxory.
Not ignorant Im just pragmatic.
We obviosly have diffrent goals in mind. Not ignorant, just diffrent goals.

Space vehicles need star catalogs to ...
Design onboard attitude determination software
Simulate on-orbit performance (will design work?)
Initialize attitude reference (where am I?)
Maintain accurate onboard attitude reference
Calibrate sensors (biases, alignments, scale factors, etc.)
Note: Accuracy critical for precision systems

Bravo!
Thank you for showing how we still use the stars to navigate, even in space. And the more accurate those positions are, the better the navigation. For any kind of mission (manned or unmanned).

Im not denying it would one day be usefull to map the stars.
But it will be a long time before we can move out there.
At the moment our priority should be to find a better and cheaper alternative to what we have now.
Once that done then start mapping the galaxy.
Not saying we shouldnt do it, just that we should do a few other things first.
