The team had originally said they were pressing on but the parent was not having it, unless they have revised their position.
In my view, the fact that they are launching an Orion on a Delta IV next year means we should stop SLS development. Take the money and put it to Delta IV man rating ...

"It is disheartening that we must continue to rely on increasingly expensive Russian vehicles to take our astronauts to the International Space Station," said CSF President Michael Lopez-Alegria. "NASA's commercial cargo program, undertaken in partnership with Orbital Sciences and SpaceX, has been highly successful in creating reliable, cost-effective American cargo delivery to the ISS, and we support NASA's continued and vigorous work on the follow-on Commercial Crew Program. Unfortunately, limited funding has delayed this program in the past and we strongly urge Congress to provide the necessary appropriations to keep the program on schedule. In difficult economic times, extending the offshoring of American jobs to Russian rocket companies is not a practice the American taxpayers should support."

Take the money and put it to Delta IV man rating ...No can do. The Delta-IV is *not* a NASA launch vehicle and the Air Force, which has final authority on any upgrades, no longer has any intention of allowing the Delta-IV to be man-rated.

ULA has said it could be ready 36 months frim an order. I'd think man rating Atlas could be done I parallel in the same 36 months. So I would think that would have been both the fastest and cheapest way to go in bth development costs and annual costs. It would probably have been ready well ahead if Orion.
Add ~15K lbs for the LAS. (Or is it intended to fly uncrewed, which would make it useless as an ISS crew transport?) Might also want to include some margin for the adapter, which for Orion-on-Ares was ~3K lbs.
Then Orion-on-Ares with a J-2X in the "ISS configuration" shouldn't have needed any SM propellant either wouldn't you think? Odd then that the SM still included ~8K lbs of SM propellant in the ISS configuration.
I think that you're overestimating Ares-I's performance. In its final iteration, it was a suborbital launcher and the Orion SM was needed to complete the ascent as well as to perform the circularisation burn.FWIW, I have always understood the primary objection to using Atlas-V-552 is that it has a very high-g launch environment for its optimum lift performance (reaching over 6g in some phases). It wouldn't be a nice ride for a crew. Most crew launchers try to keep the g-loading below 5g and ideally below 4g.
Quote from: Joel on 05/02/2013 05:27 pmDo I understand it right that SpaceX is on track to launch crews by 2015. Then for two years, NASA astronauts will continue to fly with Russian vehicles because of a corrupt Alabama senator?Careful now, that's getting a bit too far OT and we don't want to upset our hosts. Personally I'd say it's the "Gentleman from Utah" and his need to keep that SRB casting shop open that has somewhat skewed things. Despite 3 decades of STS SRB ops they still seem no closer to being able to shut them down without ripping the stack to pieces.Multiplying that by sticking a big SRB casting shop in a state with no water access to the Cape continues to ensure that the US taxpayer gets first class servicing

I doubt the senator from Alabama has much interest in sending money to the Ruskies over having an out-of-his-state US company do it.I think MOST wrankle at that situation, regardless of their personal turf wars.
They realize that the moment a commercial crew vehicle flies manned, Orion is on its death bed.
(Just like SLS will be on life support when FH flies)
Why else would their rancor against CC keeps growing, and they make more and more outrageous statements as time passes.
In my view, the fact that they are launching an Orion on a Delta IV next year means we should stop SLS development. Take the money and put it to Delta IV man rating and accelerate Orion. Any left over should be given to the company with the best chance of flying a manrated craft within the next 3 years. If we don't want to launch off of 37, then we can either crash develop the capability to launch from 39 or from 34.The goal is to either get Delta IV Heavy/Orion flying or Falcon 9/Dragon up in 36 months from contract award. Maybe its doable maybe its not. I think Gemini did it though. Surely we can do now what we did in the 60's.But I'm probably just generating wishful thinking, and the professionals will tell me I'm wrong, which is ok.
Because the program makes no sense and every time they ask NASA representatives leading questions they get more nonsensical answers.
