I would hope government agencies serve primarily national interests rather than political interests. Otherwise we may find the nation itself falling behind.
I would hope government agencies serve primarily national interests rather than political interests. Otherwise we may find the nation itself falling behind. If NASA proposes and consistently performs research and development with practical value to America, that may help to avoid the tendency for each administration to change its course based on political interests. My admittedly limited experience with other federal R&D programs is that they are less affected than NASA by changes in the administration and more likely to propose and maintain their own priorities and goals rather than waiting for the more political and less technical administration officials to decide their course.

If NASA doesn't think in political terms they quickly discover the politicians are cutting their budget or talking about downsizing some centers. Government departments serve political interests or they soon no longer exist.

The tendency to view everything in political terms is causing a lot of damage at NASA
is a serious factor, and one that promotes instability. They try to mitigate poltical interference by engaging with external stakeholders who have political influence, (e.g. aerospace contractors), but it's a delicate balancing act. With CxP they got it badly wrong and the politicians won.
Extending the shuttle also had no good reason by 2008(i.e. it would take 2 years to make a new tank at least not to mention any other problems with parts availability (like recertifying suppliers). Not to mention this does not solve the it needs replacement problem.

Not to mention this does not solve the it needs replacement problem. I believe there were/are a few extra ET's either built or partially built at MAF. I think there was an older style LWT that never got used before the switch to the SLWT, and Direct wanted to use it for J-130 and convert it to a core, becuase the J-130 didn't need wall strengthening from the ET like the J-246 did. From Wikipedia, if this is accurate:"Unflown hardware:ET-94 (older version LWT), currently in storage at Michoud Assembly Facility, will be used for development and tests of in-line Shuttle-Derived Launch Vehicle, the Space Launch System.[17]Three other external tanks were in preparation, when the manufacturing stopped. ET-139 is at advanced stage of manufacturing; ET-140 and ET-141 are in early stages of manufacturing."Which means, at least as far as the ET goes, STS could have been pretty easily extended for at least one more launch with ET-94, although it's paylaod capacity would be a little less. That probably wouldn't be a big deal as it would just like be an ISS resupply and crew rotation mission. If ET-139 is at advanced stage of manufacturing, it could likely be easily finished by the time it would be needed to fly (maybe a year after STS-135, doing one launch every 6 months). Which would put out ET-140 or ET-141 needing to be ready about 6 months after that, with the remaining tank 6 months after that. I'm no expert but I'm pretty sure that wouldn't be a problem is the extension was announce prior to STS-135. I'll assume they could have been finished if MAF had 1.5-2 years to work on them. So just that hardware could have extended STS for 4 more flights, so into mid 2013 assuming one launch every 6 months for ISS crew rotation and resupply. And if they'd ordered a few new tanks to be built at the same time they announced the extension, then they'd probably be ready by late 2013/early 2014 when an "STS-140" would have been needed to fly. Now, that's not to say there wouldn't have been other supply problems in extending the shuttle, like 4-seg booster availability (although could have it flown with 5-1 seg boosters?), just that there were enough ET's to keep flying. With the problems with CxP and later cancellation, I always thought President Obama -should- have extended STS in 2010 when he cancelled CxP, as well as to have -NOT- cancelled Orion, but continuted that as NASA's BLEO capable spacecraft. At that time President Obama could have introduced a replacement program for CxP to carry Orion somewhere BLEO to be done while cutting back STS to the bare minimum needed to keep US access to the ISS. Perhaps retire one Shuttle and store it for parts, and just kept 2 shuttles flying at a rate of about every 6 months or so. So there’s a backup in case one is grounded for some reason. The replacement program could have been Direct, or AJAX, or Evolved-EELV like Atlas V-Phase 2/3a. Granted, they must be paid for along with STS, so the transition might have taken a little longer, but the gap could have been eliminated. Evolved EELV would have the most cost sharing with DoD, but I think AJAX flying with standard Atlas V CCB’s would do a good job of that too. AJAX should have been a little cheaper to develop than SLS because it was using existing boosters, and might have been able to nix some of the J2X and 5-seg development costs by cancelling those programs a few years ago (maybe anyway). And the STS workforce could have been more gradually transitioned into AJAX (as would have been with Direct) And Evolved-EELV could have been an incremental approach, without much big up front costs to compete with STS operation funding. Start with man-rating Atlas, then start flying Orion on AVH for testing and to the ISS. If it could be made ready before commercial crew ( if Orion wasn’t in limbo for a year or so after it was cancelled) Then STS could be retired at that time, and Orion does crew rotation until commercial crew was ready to take that over. (Commercial cargo will/should already be flying by that time). Once STS was retired, those funds would go to developing AVP2 and AVP3a, and missions and hardware to fly on it, hopefully ready by the 2020’s. Anyway, I’d have much rather a plan like that come down from the White House in early 2010 (or sooner) than the way things happened. but I digress… ;-)I guess my point is they could have extended the shuttle out for longer from an ET point of view. And made a few better decisions along the way. But that's neither here nor there any more :-)
ET-94 was the twin of the tank which cost us Columbia, not safe for shuttle ops due to the foam impact issue.
ET-94 was the twin of the tank which cost us Columbia, not safe for shuttle ops due to the foam impact issue.Neither Discovery nor Atlantis were space worthy after their last flights. Each one had major systems which needed to be replaced, and no replacements were available.
ET-94 was the twin of the tank which cost us Columbia, not safe for shuttle ops due to the foam impact issue.You could not launch the last remaining shuttle without an on-pad backup, and there was none. So.... extending the Shuttle would require ignoring the Congressional edict for SLS and Orion, requiring the scrapping of both as well as other programs in order to re-establish the capability to produce the necessary bits for the Shuttle. It would be cheaper to build all new Shuttles, frankly.

Each one had major systems which needed to be replaced, and no replacements were available. I can't speak for what Discovery or Atlantis would need to keep them space worthy, as I don't know. If what you say is true, then obviously that would be a problem. How many flights could Endevour have flown and remained Space Worthy? Perhaps they could have done enough to one of them so it could have acted as a backup, but only in case of emergency for a reasonable price and effort? Not sure what needed to be replaced or why.Then just Flown Endevour as the PoR shuttle for however many more flights were needed until Orion could fly on an AVH to the ISS. I will assume (although I don't know) that if it hadn't been cancelled by the President early 2010, and hung out in Limbo for a year, that maybe at least a LEO version (Block 0 or something I think it would have been) could have been ready to fly to the ISS by 2013-2014?Maybe that’s optimistic, but I believe ULA says they could do an AVH 30 months form order, which is less than 3 years. Depends if the man-rating process could be done concurrently with that so a man rated AVH would be ready in 2013-2014.Maybe of ET-94 and the three partially built tanks, one could be allocated for the backup mission (if Discovery or Atlantis could be made to be back-up flight worthy), and then Endevour could have flown 3 more flights after STS-135 using the other three ET’s, at a rate of once a year. We’d still need to probably buy some seats on Soyuz to go with that, but at least we’d still have some capabilities.

It would be cheaper to build all new Shuttles, frankly.Ummm…I said if President Obama had come out with such a plan instead of the one he did in February of 2010 (or even came out with it earlier), so that there never would have been a need for a Congressional Edict later in 2010 in NAA2010. –Before- there was such an edict. However, if there were parts other than the ET’s that would be needed to start production of again to make a backup Shuttle available, and if doing so was cost prohibitive, than you are correct, STS-135 was the last mission that could have flown. But again, rewinding time back to early 2010, or even further to mid or late 2009, and reorganized the remaining manifest to extend out the launches, it might have opened up some other possibilities.There were 3 shuttle launches in the latter half of 2009, with one before that in May 2009. There were also 3 launches in 2010 (would have been 4 if STS-133 hadn’t had issues). And 3 launches in 2011.That’s 9 launches right there. So, let’s discount STS-125 on May 11, 2009 as that was the Hubble mission, the ISS mission prior to that was STS-119 on March 15, 2009. The next ISS mission was STS-127 in July 15, 2009. That could have been moved out to September 2009, 6 months after STS-119. (This decision could have been made by the Administration while the Augustine Commission was mulling over the various alternatives to CxP in the summer of 2009. A tentative plan could have been made to move out the remaining flights at 6 month intervals, pending the findings of the Augustine commission, and a real plan by the Administration to follow for either Direct-like, AJAX-like, or evolved-EELV. Then reevaluated depending on the projected time for Orion/LV or commercial crew to be ready to service the ISS. ). STS-128 Could have then been moved from August 2009, to March 2010. STS-129 could have then been moved to September 2010. STS-130 to March 2011. STS-131 to September 2011. STS-132 to March 2012. STS-133 to September 2012 (and then Discovery would be retired with much deserved fanfare). STS-134 then moved to March of 2013. Then STS-135 would not fly with Atlantis, but Atlantis would be parked and she’d be held in reserve as backup to Endevour. STS-135 would fly with Endevour in September 2013. By allocating 3 of the 4 remaining tanks to STS-136, STS-137, and STS-138 (finishing the 3 partially built ones). Endevour would fly STS-136 and STS-137 in March 2014 and September 2014. STS-137 would be her last scheduled launch, so that could have all of the “retirement” fanfare. But then she’d be held in reserve until Atlantis flew her last flight STS-138 on March 2015, where she’d be retired with her fanfare, like she was on STS-135. One ET would still be left unflown if the rescue mission was never needed.That would have given NASA until September 2015 (6 months later) to either have Orion ready to fly crews on AVH, or a commercial crew provider ready. I think that would be doable. STS is then completely retired and resources are then shifted completely to finish whatever system would be replacing her, Direct, AJAX, or Evolved-EELV’s. Looking back over the shuttle manifest, I see several cases where the same shuttle was flown twice within 6 months, so flying Endevour every 6 months on STS-135, 136, and 137 wouldn’t be a problem I wouldn’t think. It would have delayed the last few pieces and parts of the ISS over another few years, but all of the big parts were already there by STS-119 in March 2009 except the JEM EF, and Node3/Coupola. I’m sure I’m missing a bunch of important details here…but just saying with a different plan earlier on, the gap could have been all or at least mostly avoided.
According to Wayne Hale they'd begun to destroy the tooling and support for the Shuttle as far back as 2004. By the time Obama had taken office, over 4 years of dismantling had happened.
Saaaaaaaaaaay What! Back on topic after this post (no, "but but but...") On topic from now on. Thanking you.
For the record-In 2008 Musk gave Hillary Clinton $2,300...etc.
The tendency to view everything in political terms is causing a lot of damage at NASA even though (or perhaps because) it is rarely discussed. I was actually told by a high-ranking civil servant that "Obama is using SpaceX and the Unions to destroy NASA".

What about NASA employees going native?
QuoteWhat about NASA employees going native?That would be the best thing that could happen to them. Almost every USA contractor, all the people who had actual hands-on experience with flight hardware, were fired and dispersed. No one even asked them to record their ideas. The NASA personnel all kept their jobs, but almost none have ever designed, built or maintained actual flight hardware. They consistently take more time and spend more money just deciding on the text of a few requirements than an expereinced engineer would take to actually design and build the system. Cost is what is killing human spaceflight, and NASA is going to have to learn to act a lot more like SpaceX if cost is to be controlled, let alone reduced to a practical lavel.

What does LSP do to make unmanned launches less expensive?
