Docm, I do not think that a filibuster will be needed in the Senate, as the Democrat majority in the Senate has already approved the full funding of such private efforts, and it IS the Republicans (that even for political opposition to anything Obama, I find such a position to be greatly incorrect at best, and reprehensible at worst) that are the problem in the House. If a bill that truly parallels the Senate version were to pass then evidently Elon Musk and spacex would have no problems with it!
It is indeed with a certain amount of regret for myself that I do not have to communicate with my congress persons on this issue, as the are all Democrats that will be supporting having NASA move on while actually paying such as spacex for the more mundane duties of getting materials and eventually people to and from the ISS. However, I will contact my local Congresspersons office just to make sure he knows that this issue has my full support. However, not only is he a Democrat in support of this, his district also includes such a rocket giant as Rocketdyne, and so I can not imagine tha this vote would be a problem (at least if he wants to retain his seat in Congress).
However, if yours are Republicans that might vote for these cuts, then please contact them with your displeasure on this particular point! Hopefully, at least some Republicans have enough integrity that they are not so election minded that they would oppose Obama on everything, just for the sake of possibly taking back the power in Congress. To me at least that is like throwing out the baby with the bath water.
While I know that we do oppose each other at times on the more political issues here, you have always been a good supporter of the space program and getting humanity out into the greater universe. So, not only do I thank you for that position, you will never experience opposition from me on that particular issue!!
In fact, I would like to see the total space budget for not only NASA brought up to at least 1.0 % of the federal budget, but more money also given over to all private space efforts to truly stimulate the economy into hiring more scientists, engineers, machinists, inspectors, and all other Americans in good paying jobs with reasonable benefits, to truly place the US in the position as total leader in the world for this area. Especially as it IS the LAST such area the we are still the best in the world at!
Now, that would be a REAL stimulus package!!
