Quote from: sdsds on 08/23/2010 11:40 pmIt's quite interesting to read that some spaceflight supporters in Washington D.C. are still keeping alive the dream of a substantial extension to the Shuttle program! It seems this is now principally motivated by a desire to fully support ISS.While that kind of thinking may be politically viable, from a dispassionate technical perspective those dreams look unrealistic. Instead the reality seems to be that decisions made long ago have left ISS in a posture where its continuation is exposed to some risks, and no amount of funding now can mitigate those risks in a timely fashion.This is due to the historical (or should I say hysterical) way HSF is funded ... we play a collective game of "chicken" at the end of a program, forcing a clumsy transition. Political theatre to force a budgetary endgame ... which gets mangled by legislators doing rocket design for favoring special interests.As long as HSF is still too much of a "circus act", this will happen.

Give NASA a multi-decadal mission and let it supplement it's federal funding from private sources. It's HSF future will then be tied more to the interest of the nations' people and less to the special interests of the Legislators.

Here's a wild idea: Has anyone ever looked into adding some kind of additional "workshop" module to ISS to support full utilization? It could be used for maintenance and tinkering with various experiments on-board (people have been asking about VaSIMR). Or, if it's got enough room, failed components could be investigated there in lieu of downmass opportunities. Of course, if those things couldn't squeeze into Dragon for a ride home that means it would have to be quite spacious itself, perhaps an inflatable with an oversized airlock?Long ago our space station was envisioned as an orbital assembly station. This could be a cool way to take one step in that direction. Maybe even have some on-orbit manufacturing and assembly experiments.
No viable. a. Astronauts are not real techniciansb. Spacecraft are full of bad propellants and pyros.c. Not enough air to waste in airlocks that larged. No spacecraft in the vicinity of the ISS
Yes viable.1. They are quite amenable and able to be trained for assembling large items in space, with the assitance of Canadarms and Robonauts built for the purpose.ii. This has not stopped the current work at all.c. If we're gonna work in space, we'll have to bring up sufficient O2, no matter what the future holds.IV. To quote Jed Clampett: "Every time we hear that bell, someone's at the door!" Every time the shuttle, a type of spacecraft, gets in the vicinity of the ISS, crew members ring the doorbell!
1. big difference than fixing black boxesii. None of the work has a spacecraft inside a pressurized spaceIII. we are talking current ISSiv. shuttle will be gone and this is about other spacecraft.

1. I never said anything about an entire spacecraft assembly and construction workshop. 2. I was definitely thinking of a ISS module or Bigelow inflatable style workshop...
1. Good. I never said you said. And the biggest thing needing technical examination that I mentioned by name was the ammonia pump.2. I said: "The original question was adding a "workshop" to ISS." Seems like your and my statement are roughly equivalent.Not sure what yer drivin' at.
1) Why you don't novate the contracts now(51D's point):Because too much of the existing contracts drag along cost centers that make it impossible to fit in the budget footprint Congress will end up with.Can't until you get to appropriations.2) What has to happen to get to a more rational (e.g. less earmark driven) NASA exploration funding model (clongton's point):Because too much depends on a cold war industrial policy model you can't have ANY modern one that replaces it. I gave you an example of how to replace it and why - go find a way to map it into your politics somehow, that's not my problem.Until then, we'll keep on biting our own a$$ with "projects to nowhere".Tell me when you get tired of failures.

I get the feeling that this termination laibaility issue will only be resolved once the NASA Authorization bill is law and once the contracts are novated. I imagine that if a company refuses to novate its contract for whatever reason, the termination liability issue would still be relevant.

On the continuing resolution, if no agreement on the new authorization bill can be hammered out in time, would the continuing resolution just continue the POR for another year? If so that seems a waste.Or would it be some kind of a middle ground study phase where just no real work was done on the new system.
...none of the funds provided herein and from prior years that remain available for obligation during fiscal year 2010 shall be available for the termination or elimination of any program, project or activity of the architecture for the Constellation program nor shall such funds be available to create or initiate a new program, project or activity, unless such program termination, elimination, creation, or initiation is provided in subsequent appropriations Acts.
Provided further, That notwithstanding any other provision of law or regulation, funds made available for Constellation in fiscal year 2010 for ‘National Aeronautics and Space Administration Exploration’ and from previous appropriations for ‘National Aeronautics and Space Administration Exploration’ shall be available to fund continued performance of Constellation contracts, and performance of such Constellation contracts may not be terminated for convenience by the National Aeronautics and Space Administration in fiscal year 2010’’.

Whether novating Ares I SRB, avionics, upper stage, LAS, and MLP contracts into contracts for such an Ares V would be allowable under a CR is a good question. It almost seems like the worst that would come out of this would be more work on the 5-seg SRBs, J2-X, and a 5m upper stage....which could all eventually be applied to SLS if they happen to be available. But it also seems to me that the if appropriators could insert language amending the CxP termination clause into the Spring 2010 supplemental appropriations bill, they could just as easily insert a new amendment into the CR that allows NASA to negotiate the novation of Ares I contracts into contracts more suitable for the Senate's preferred HLV.
There's been some talk about downmass capability after Shuttle retirement (or lack thereof) in this thread, so I found this article on spaceflightnow.com interesting:Europe, Japan weigh cargo return from space station (http://spaceflightnow.com/news/n1008/27cargoreturn/)In it is some information about how both ESA and JAXA are studying/planning to add the cabaility to their ATV and HTV to return cargo through a capsule. Both are designs that could evolve into crew launchers eventually.
