US Manned Space Flight Taking a Budget Hit
An anonymous reader points out that Congress has quietly begun dismantling NASA's manned space flight program. "Other recommendations contained in the bill include a $77million reduction in NASA's proposed space operations budget, which includes the space shuttle and international space station; a $6 million reduction in science; and a $332 million shift in funds from the Cross Agency Support account to a new budget line-item included in the subcommittee's mark. Dubbed Construction and Environmental Compliance, the new account would be funded at $441 million. Congressional aides said the new line item and accompanying funds are aimed at consolidating NASA's various construction efforts into a single pot of money."
Wow, an astounding amount of ignorance is on display in this post. Near Earth Asteroids (NEAs, or NEOs if you prefer) may indeed be easier to visit than the Moon, and they are quite a bit easier to visit than Mars. Mainly this is due to the lack of appreciable gravity, so that the escape velocity from the surface adds only a negligible delta V to the total delta V budget required (for both landing and taking off again). You're not going to find yourself on a 100+ year orbit on an NEA. If you did find yourself on a 100+ year orbit and on on your way out of the inner solar system, then, by definition, you would have landed on a Halley-type comet (or perhaps even a long-period comet if you were *really* on your way out). Take as a typical NEA 433 Eros. The NEAR spacecraft successfully landed on it, despite the fact that the spacecraft was designed to be an orbiter (which, I think, succinctly illustrates how easy it is to land on an asteroid). Its perihelion distance (closest approach to the Sun) is 1.13 AU (1 AU is the Earth-Sun distance) and has a period of a bit less than 2 years. Once nice thing about asteroids is that they basically represent remnants of the original solar nebula from which planets were formed, and most of them never differentiated (melted and formed iron cores and rocky mantles). That means that they are relatively rich in many raw materials compared to the surfaces of planet-sized bodies. A carbonaceous asteroid contains valuable metals (often as little blobs of pure metal), water (up to 30% by weight in many cases), and organics (kerogen). Some other asteroids are nothing but metal, and would require very minimal processing to make them useful (unlike many ores found on Earth). Going to asteroids makes a lot of sense. The main difficulty with an asteroid vs. a lunar mission is that the mission length to an asteroid would be longer than one to the Moon (although depending on the asteroid, it could be much shorter than a Mars trip).
That's what the urban legend says. But it's utter bullshit. The Apollo computers and guidance system were based on those of the Polaris A-1/A-2. The USAF and the USN miniaturized the computers and guidance systems, all NASA did was issue spiffy press releases.
You find the same thing almost universally when you run down the list of technologies 'developed' by NASA. They were first developed by someone else, and then like a technological Sylar NASA sucks them up.
The tragically ignorant are people like yourself who endlessly regurgitate NASA press releases. As far as results for dollars expended, the NASA PR department is probably the most efficient in the US government.
