Senate Bill Adds Shuttle Flight, New Shuttle-Derived Vehicle 230
simonbp writes "The Senate Commerce Committee this morning marked up a compromise NASA Authorization Act that rolls back some of Obama's plans for NASA, while keeping others. The bill adds at least one more shuttle flight, keeps Obama's technology demonstrators and commercial access to ISS (albeit at reduced funding), restores the Orion crew capsule, and replaces the Ares rockets with a Shuttle-Derived 'Space Launch System' for going to the ISS and Beyond, which could be ready as soon as 2015."

oddly enough the shuttle has the same safety as soyuz with roughly 2% failure. Of course no one wants to actually say that. We have lost 2 shuttles, but have launched 2.5 times more shuttles/people than russia has 3 man capsules.
No a new smaller reusable capsule for personnel launches, and then a larger heavy lift rocket for equipment combined with a manned space station would be a far better option. Instead of launching the lab up with every launch.

I was told by people who work on the Shuttle that a decision to run another shuttle flight should have been made 1-2 years ago, that there are not enough spare parts to do this, and that this is basically throwing good money after bad.

Well, if there's a time gap between when the shuttle retires and when its replacement arrives, you will want to keep some spare parts laying around. What if someone spots an big-ass asteroid hurtling our way? We will need something that can fly Bruce Willis up there and save the day.
I know you're joking, but FYI the US already has quite a few commercial launchers available which could send up Bruce Willis and Steve Buscemi to the incoming asteroid:

Obama says, "Screw the moon, I'm setting up a 20 year project to go to Mars."
But that's not what he said. He said "I'm creating projects to develop technology that could enable a mission to Mars in 20 years", and that's a huge difference. He's talking about developing general technologies and capabilities that would be useful for a wide variety of missions outside of Mars, and if nobody wants to pull the trigger on the Mars mission in 20 years, we still have all the technology and capabilities. Mars was only mentioned to make the people who think we must have a specific mission happy (and it's not a bad policy to at least have a practical application in mind).
Whereas a definite "Mars in 20 years" would mean lots of development of tech designed for that mission and only that mission. 20 years to have enough technology in place that a Mars mission doesn't require that much specific development is a much more sensible, useful, and future-proof plan.
But hey, I guess having a giant expensive rocket that can't do anything rockets of 30 years ago couldn't do is nice too. :/

"That's fine and all, but the fact is that the STS systems are already developed and in production"
No, the STS systems are developed and were in production. It's no longer the case that they are in production. The launches remaining will be flown with parts on hand.
NASA was directed to close down the project several years ago and has faithfully executed its orders to do so. Now the supply chain is broken and scattered. (Staff fired, tooling scrapped, etc etc.) There is no reviving it without costs approaching well within a magnitude the development of a new system. The time to revive the shuttle (if ever there was one) passed no later than a year after Bush first killed it.

Let me try, using your timeline as a base (feel free to modify/copy/reuse):
2003: Space Shuttle Columbia accident
2004: Bush announces Vision for Space Exploration [nasa.gov] for sustainable human presence on the Moon starting in 2020 as testbed for Mars exploration and expansion into the solar system, calls for shuttle retirement in 2010 and replacement crew capability in operation by 2014, calls for commercial cargo/crew to ISS and no new launch vehicles developed unless absolutely necessary, NASA solicits plans from industry for best ways to achieve these goals
2005: Sean O'Keefe resigns as NASA administrator, Bush appoints Michael Griffin and gives him free reign with NASA, Michael Griffin throws out industry studies and NASA releases ESAS study which has NASA design two rockets in-house instead of utilizing commercial rockets (The Ares I and V, coincidentally based on old designs Michael Griffin came up with), ostensibly because they're "safe, simple, and soon" compared to alternatives
2005-present: Ares I development slips in schedule a year for every year that it exists, costs balloon from a few billion dollars to tens of billions of dollars, 2020 lunar date becomes increasingly unachievable
2009: NASA and White House appoint Augustine Committee, consisting of best and brightest from aerospace and astronaut community, to evaluate Constellation's progress and come up with options for future of
human spaceflight at NASA; they release a report [nasa.gov] presenting a number of viable options for NASA's beyond-Earth exploration plans
February 2010: White House calls for boost to NASA's budget (but not as large as Augustine Committee presented) releases plan similar to Augustine Report's option 5B [spacepolicyonline.com], calling for investments in commercial crew and long-neglected space technology and cancellation of Ares I, delays building of heavy-lift launcher until 2015 since it won't be needed until then; a lot of congressmen in space states freak out
March-July 2010: lots of back and forth discussion and congressional hearings, Armstrong and Cernan come out against White House Plans, Buzz Aldrin comes out in favor; NASA scales back Ares/Constellation program without congressional approval, ostensibly to comply with termination liability laws
June-July 2010: NASA announces a bunch of new space technology initiatives (contingent on White House funding plans coming through), including new Centennial Challenge [nasa.gov] prize competitions (Nanosatellite launch, night rover, and sample return robot challenge) , revived NIAC to research experimental concepts, in-space technology demonstrations/missions utilizing in-space refueling, inflatable modules, electric propulsion, and inflatable reentry shields, all launched on existing commercial rockets
Today (July 15): Senate comes out with compromise bill, adding 1+ shuttle flight using existing equipment (no backup rescue shuttle if there's a problem, though); immediate development of 75mt shuttle-derived rocket quite similar to the one proposed by the DIRECT project [directlauncher.com], more commercial crew, robotic precursor mission, and space technology funding than 2010 but much less than Obama requested (over three years $1.6B vs. $3.3B for commercial crew, $244M vs. $1.33B exploration robotic precursor missions, $2.1B vs. $8B space technology development/missions); White House and Congress potentially both support the compromise, though

No, we are about to rely on a private company, Space X, to ferry astronauts to the ISS.
Actually, even SpaceX's Elon Musk has stated that SpaceX will probably be a smaller provider, with the United Launch Alliance's Atlas rockets getting more of the commercial crew funding. For those unfamiliar with them, the ULA has had 40 consecutive successful launches in 40 months, often carrying multi-billion dollar DOD payloads critical to national security, so it's pretty indisputable that they have proven rockets. This produces a competitive market in commercial spaceflight, which is of the utmost importance to avoid all the problems inherent with monopolies.

Unfortunately that 'prototype' shouldn't be called that. The Ares 1 was designed as a J-2X engine on top of a 5-segment SRB.
The Ares 1-X however was intended solely as a test of the aerodynamics of the launch vehicle. As such, none of the other components had to be anything like the final one. The first stage was merely a 4-segment SRB, the same type we use on the shuttle, with a dummy 5th segment. That may not sound like much, but changing the length of the engine chamber means they have to completely redesign the fuel grain and that won't be done till 2017ish. The second stage is still completely non-existant - the one on that launch is a dead mass. Even the control system is just one they stole from a Titan missile.
And all of that cost more than $500M. While I dislike bringing up SpaceX in this sense, because Falcon 9/Dragon is not as capable as Ares 1/Orion, this is comparable to all of the money that SpaceX has spent so far.
Sadly you've been fooled by a publicity stunt meant to convince people that a program that was way behind schedule and over budget was actually making progress.

The idiot just looked up the number of launches of "Soyuz" (without any scary additions to the name like "-U" or "-FG" for example) rocket, the first variant which was named like that (after the vehicle it started carrying back then) - really, all just R7 variants (though for the longest time also direct derivatives of the first Soyuz one)
What he did is especially ironic considering that the rocket flew over 1700 times, and according to ESA [esa.int] (for whom it is a very succesfull competition) is "the most reliable means of space travel" and "the most frequently used launch vehicle in the world."
