yes, the falcon 9 heavy *does* use 27 engines in total. thats the freaking point. if a any one of the few engines on a delta IV fails, the rocket is a goner. if a engine, or even a few, fail on the falcon 9, it can still complete its mission, the other engines just have to burn a bit longer. its engine redundancy, in the fine tradition of rockets like the saturn 5, which had no failures, despite a engine failure mid-flight on apollo 13.
How about using one of these as a sort of space tug, where it docks with satellites inserted into low earth orbit, receives a amount of fuel from the satellites to top up its tank, say through the docking interface, and then over the course of weeks or months, raise it to a higher orbit, like, say, geostationary orbit. power could probably be beamed from a solar array in orbit to the ion engines. No atmosphere to get in the way. No need for the satellite (or cargo) to carry a large amount of fuel, or significant propulsion system.
Even with the extra fuel for the tug to get back down to low earth orbit to pick up the next satellite, at a isp of 30,000, it would be more efficient than using extra boosters.

i think you mean "standard encumbered with patents, and not covering the whole libary" and while it is true that it is a interpreted language like java, its syntax is a lot like c++. Although, your probably right. I really shouldn't compare it to c++. thats a insult to c++. Its more like visual basic.
The really interesting bit will be when they fish the lower stage out of the ocean, and see what they will have to do to get it suitable for another flight. I hear that it might be only a few valves that would need replacing.
165kg is just the weight of the dummy module to put into orbit you moron. if you took the 5 seconds itd take to go and check the spacex website, youd see it can actually put around 1 tonne into orbit. and thats before any sort of reusuability is taken into account. so next time, think before you open your moron mouth.
Bloody hippy paradise. Intangible benefits to public transportation? How bout the highly tangible drawback that public transport could never be as convenient as a car. Oh, and good luck carrying anything large. Also, people aren't gonna hug their neighbors more cause there on a bus.
Radiation? The only radiation source is fusion at the core of the star, The only thing this star radiates is Infrared. i.e. Heat. to get any ionizing radiation, youd prolly have to be near the core. It probably looks like a particularly active really big gas giant.
Ohh. I see. Habeas corpus is for US citizens only. And since the enemy don't follow the Geneva convention, it makes it ok for us to not follow it. Cause its not "Human rights" its "People who follow the Geneva convention rights".
Why would you want to model a human brain? I understand the reasoning of figuring out how the brain works, but if your going to make a intelligent system with the flexibility and ability to learn on the scale of a human being, I would think you don't have to emulate a human brain. Just emulate some of what seem to be the most important characteristics of the brain, and somehow take full advantage of the fact that most of the physical and biological restraints that apply to a brain do not apply to a software system.

yes, well that was 30 engines on a rocket much larger than falcon 9. 40 years ago. i imagine control systems have come some way since then.

the essential difference is that java is open sourced.
All the latest news on Microsoft's slightly altered and nonstandard and proprietary version of the c++ language. Oh goody.

any chance anyone posted some video of the launch somewhere? spacex hasnt got it up on their site yet, and i missed the fing webcast...

I like PETA, but I couldn't eat a whole one.

Man. I really hope this succeeds. I always get a warm fuzzy feeling whenever a lot of bankers hit the wall.

Yeah but id bet they'd prefer to make money on both..
..They just swooped in, spat out some kickass gear, put up itunes, and showed those music exec morons how to do it properly. BAM!
Swing and a miss. nonstandard dvds, nice try, please come again.
