Senate Panel Authorizes Money For Mission To Mars (usatoday.com)

An anonymous reader quotes a report from USA Today: With a new president on the horizon, a key Senate committee moved Wednesday to protect long-standing priorities of the nation's space program from the potential upheaval of an incoming administration. Members of the Commerce, Science and Transportation Committee passed a bipartisan bill authorizing $19.5 billion to continue work on a Mars mission and efforts to send astronauts on private rockets to the International Space Station from U.S. soil -- regardless of shifting political winds. Under the Senate bill, NASA would have an official goal of sending a crewed mission to Mars within the next 25 years, the first time a trip to the Red Planet would be mandated by law. The legislation would authorize money for different NASA components, including $4.5 billion for exploration, nearly $5 billion for space operations and $5.4 billion for science. Beyond money, the measure would: Direct NASA to continue working on the Space Launch System and Orion multi-purpose vehicle that are the linchpins of a planned mission to send astronauts to Mars by the 2030s. The bill includes specific milestones for an unmanned exploration mission by 2018 and a crewed exploration mission by 2021. Require development of an advanced space suit to protect astronauts on a Mars mission. Continue development of the Commercial Crew Program designed to send astronauts to the space station -- no later than 2018 -- on private rockets launched from U.S. soil. Expand the full use and life of the space station through 2024 while laying the foundation for use through 2028. Allow greater opportunities for aerospace companies to conduct business in Low Earth Orbit. Improve monitoring, diagnosis and treatment of the medical effects astronauts experience from spending time in deep space.

Lots and lots and lots of breakthroughs and developments that would otherwise have taken decades instead of being done "before this decade is out".

Dedicated positions with defined interfaces between them, and how this is being documented and interwoven with technology, was a complex but crucial part of the organization of the moon shots.

    You're confusing budgeted and actually spent. Wartime expenditures are not restricted to budget.

    This is a really good point. In fact, most of the cost of the Iraq and Afghanistan wars was funded off-budget: the Congress would pass their budget not including costs for the wars, and then do a supplement later to fund the wars. A lot of the cost is not accounted to the war. The cost of munitions, for example (the munitions were bought under general military budget, and when they were used in the war they had already been paid for. Of course, they have to be replaced... but that's not cost accounted to the war.

    For example. On paper, we budgeted only a few billion for wartime expenditures between 2001 and 2006, yet the actual money spent was in the trillions. My poli-sci teacher said in those 5 years, we spent enough money on the war to fund all healthcare and college for all of the USA for 10 years.

    The GP is correct, the hypergolic fuels are much worse for the environment. Some experimental ones have been even worse, such as boron-boosted (zip fuels) and fluorine-based fuels. Crazy-high performance - the highest ISP rocket engine ever built was a fluorine-hydrogen-molten lithium triprop** - but they're a nightmare to work with. I can guarantee you that if beryllium wasn't so crazy expensive it would have gotten a shakedown as well.

    ** The fun thing in that rocket is that the hydrogen both enters and leaves in the same form, H2. It exists solely to function as a working gas, to maximize the expansion potential of the heat released from the lithium-fluorine reaction. A lot of things with rocket propellants are counterintuitive that way - for example, with aluminized hydrocarbon-based rocket propellants, the optimal combustion is to burn the hydrocarbons to H2 and CO, not H2O and CO2. It's not worth the extra energy release to carry more oxidizer, and you need as much light gases as possible to transfer the energy from the aluminum since it condenses out of the gas stream at high temperatures and thus can no longer contribute directly to expansion.

Create a quasi-governmental authority with the power to tax people up to, say, thirty-one billion a year for the next twenty years. That would be, adjusted for inflation roughly Apollo's annual funding but extended over about twice the program duration. If that sounds insane to you, it's because we don't do that kind of thing anymore.
