Want To Buy a Used Spaceport?

The summary makes absolutely no mention at all of the next-gen rocket, SLS (capable of well over 100mT to orbit), which is being finished up. The boosters for it have been test-fired already (as have the main engines, which are left-over Shuttle main engines, and the upper stage for now is a big version of the Delta IV upper stage), and it is on-track for CDR. SLS will use LC-39A and the VAB. NASA and Florida are just looking for others who would also like to use the facilities, since they won't be in constant use. Boeing is already using one of the Shuttle processing buildings for their CST-100, which is part of NASA's "commercial crew" program and is already very far along, having tested its parachutes, heatshield, abort thrusters, airbags, etc.

Now, I'm quite skeptical with the idea of going back to 100+mT rockets for exploration instead of multiple commercial 15-30mT rockets (which have other, current customers and so are cheaper and will be around as long as the US is a country and which may shortly be capable of reusable flight), and especially I'm skeptical of the zipcode-engineered SLS, but it IS the current plan and it has lots of Congressional support and I'll cheer it along and enjoy its launches. People deserve to know that it's actually being built and that the VAB and LC-39A are going to be used by it, not all this BS about "oh, 'Bama canceled NASA, so they're having a fire sale." NASA's budget is still about the same (which is only about half of a percent of the federal budget, by the way), and the International Space Station is doing just fine with NASA astronauts in it, being resupplied with cargo by American spacecraft (SpaceX's Dragon right now has made two successful supply runs up and safely back down, soon to be joined by Orbital Science's Cygnus), and soon Dragon will be also shuttling the astronauts up and down to Station. http://www.nasaspaceflight.com/2013/01/yir-part4-iss-new-year-successful-2012/ [nasaspaceflight.com]

Oh, another thing is that NASA is currently experimenting with a deep space habitat based on ISS modules and a Space Exploration Vehicle for going to asteroids or the moons of Mars. NASA retired Shuttle, and a dang good thing, too! Now we can really go explore beyond the confines of the Earth's gravitational influence.

Also, NASA's Orion capsule is VERY far along, has done several tests already and will do its first orbital test in the late 2014 time frame. This means by the time President Palin (or whathaveyou) is inaugurated, NASA will have essentially 3 man-rated capsules (Dragon, Orion, and Boeing's CST-100) already flight tested and a big-ass rocket built and prepping for launch (in 2017). NASA is NOT fracking canceled.
