as a generic tax payer and space advocate. What is the best path forward for future manned space exploration/expansion? Is it really holding on to the Shuttle infrastructure?
Technically in the bill it is a US short ton unless the word metric or tonne is specifically used.http://en.wikipedia.org/wiki/Tonhttp://en.wikipedia.org/wiki/Tonne
Oh really - What part? - That we can't afford 150 mT payloads in the foreseeable future? - That we can't build 150 mT, 200mT, or 500mT lifters, *and* afford their payloads?

Is it really holding on to the Shuttle infrastructure?I do not wish to derail this thread by petty remarks, but I have to weigh in on this one.Taxpayers expect government to hand everything to them for free, ensure that everything works without issue, otherwise they can their butts when they feel disgruntled. Taxpayers (in general) are just as much part of the problem. (I'll leave the issues of job creation to a sperate forum).

We can build 70mT payloads and many are on the drawing boards as listed in many places on this forum.There is no need for a 150mT vehicle today and no one has suggested such. Plus there are no legitimate 150mT payload on the drawing. Maybe 10 or 20 years from now, if or when there is a need for a150mT payloads, we might upgrade a vehicle for that or as some have suggested build it in 2 pieces.

I was merely responding to OV-106 writing that nothing in my post had any basis in reality. Don't take it out of context.
NASA can build and fly a SDHLV under its current budget, but it will need some kind of budget increase to actually fly something regularly on it (EDIT: without gutting other critical areas almost entirely, that is).

CxP is going away, except for Orion, but the money is really not. Shuttle, in its current form is going away. With respect to STS, the largest part of the program in terms of budget and manpower is related to orbiter. If that is no longer needed, then logically, a SDLV should be considerably cheaper.If "commercial" is to reduce the cost of transport to LEO significantly reduce transportation costs where those can be purchased firm-fixed price, how is so many are saying there is no money for anything?

That money has been returned via the White House's and Senate's FY2011 compromise. And notice I said "regular" HLV missions. That means at least 5 or 6 launches a year, not of a reusable payload (like the orbiter), but of newly fabricated aerospace-grade hardware. That's expensive. Specialized payloads typically cost around $100,000/kg, but even if you can somehow reduce that to $10,000/kg, we're still talking 3 or 4 billion dollars. Remember, ISS is sticking around until at least 2020, now. And it doesn't require hundreds of tons of supplies every year.Of course, this is sort of bass ackwards. The payloads are why the launch vehicle exists, not the other way around.
...Cutting the hairs pretty thinly there.

Another presser - not sure what Columbia has to do with this...?
Mike which proposal do you think will win out: House or Senate?
