By definition it wouldn't be a case of starting completely from scratch though. I can understand it was insanely expensive the first time round when it hadn't been done before and the whole concept of space flight had to be researched and 'invented'. However we've kinda been there and done it now. The science for LEO is here, the technology for LEO is here. With all the space knowlege and improved manufacturing process's that have developed in the last 50 years it shouldn't be anywhere near as expensive to design and build an upto date system as it was with STS
Having said that space flight is still probably one of the greatest engineering challenges and until there is a market akin to the aeornautic industry, with producion line manufacturing etc the bottom line is going to be heavy. However without progress that bottom line is gonna stay heavy.
Which means that all those gorgeous images the previous poster was talking about will no longer be available other than with false color.
Umm all those gorgeous images currently available are, false colour.

Taking color pictures with the Hubble Space Telescope is much more complex than taking color pictures with a traditional camera. For one thing, Hubble doesn't use color film -- in fact, it doesn't use film at all. Rather, its cameras record light from the universe with special electronic detectors. These detectors produce images of the cosmos not in color, but in shades of black and white.
Finished color images are actually combinations of two or more black-and-white exposures to which color has been added during image processing. The colors in Hubble images, which are assigned for various reasons, aren't always what we'd see if we were able to visit the imaged objects in a spacecraft.
Hmm ive been doing this since 2002 on my old Nokia 7650. I mostly use eBook reader eBook reader for Symbian phones now on a 6600. There are loads of document readers/editors available from.pdf to MS word. I guess as the article says "Such times could be just around the corner in the United States, where cell phones are become increasingly used for relaying data, including video, digital photos and music.". Oh wait this is already available worldwide.
Does GTA really promote the murder of prostitutes? If you did actually have sex with a prostitute then murder her within the game this would attract a police wanted level. So rather than promoting such an act it devalues it.
Talk of fastest collisions brought to mind something i saw on the Dicovery channel which would surely be a contender for the fastest earthbound collision. The project in question is a 4 stage rocket sled that accelerates a 192lb instrument package into a concrete wall at mach 8.5. The video on the documentary was quite impressive showing the simulated warhead punch straight through about 5 meters of concrete. Cool picture showing shock waves produced when you can do 0-6500mph in 6 seconds.
So, no.. you're not expected to have faith in a researcher. You're expected to have faith in the academic community which reviews, retests, reconsiders, and scrutinizes those papers daily.
Isn't that the problem, how can anyone including the acedemic community review a project without access to all the data?
It may be mild in comparison to SS and Gestapo techniques but add that up night and day over 3 years and I'm sure if it was you being subjected to this 'extremely mild torture' you wouldn't be so quick to dismiss it.
What would be *really* *really* cool is if people stop posting counter corrections to smug corrections highlighting the possiblility of low probability situations that could validate the parent.
Maybe these robots could to be sent up in the shuttle when it returns to flight. That way we could observe their behaviour and finally find out if ants can be trained to sort tiny screws in space!
This poster is possibly being a little hasty, but he will not be reaffirming his allegiance to this simpsons quote due to its gratuitous appearance on/.
I think the device you mean would be a DeBigulator. Of course to return to normal size would require some kind of ReBigulator, which is an idea so patently absurd I can't even begin to comprehend it, ng'hiey!
Wow! cool so EA can churn out games even cheaper and faster while charging me the same and all i have to do is buy more expensive hardware! ....Hang on, that doesnt make sens............DID YOU SAY 512Mb! quick quick where do i sign!?
" There has always been ghosts in the machine, random segments of code that have grouped together to form unexpected protocols. Unanticipated these free radicals engender questions of free will creativity and even the nature of... the soul. Why is it that when some robots are left in the darkness they will seek out the light? Why is it that when robots are stored in an empty space they will group together rather than stand alone?... how do we explain this? Random pieces of code? or is it something else.

When will the world learn... computera and hackers aren't something to be afraid of, I mean I'm talking to you through a computer right now... wait... infact I am a computer!
The problem is that the market was much smaller in 1985 so prices had to be higher, since then the computer/software market has exploded. Todays product may be $300 cheaper considering inflation but I suspect it should be a hell of a lot cheaper considering the increased consumption.
I dont think relativity states you would go back in time if you traveled at c. Rather it predicts that time would pass slower for you relative to the rest of the universe, or things not going at c?

The ENGINE will have a better horsepower/weight ratio.
As per your concept of engine efficiency improvement/modification/butchery only considering the engine.
A 600BHP V6 engine of weight 200kg (with two duff cylinders producing 75BHP each) The PWR of this engine is 3
Remove two faulty cylinders, approx 33% of engine weight, giving us a modified weight of 167kg. Now producing 450BHP The PWR is now 2.69
Now you can quote me on this
Worst... analogy... ever...
This would imply over 80 missions have been flown without informaton as to what extent impacts to the tiles would damage them?
I know the shuttle flies with the engines facing prograde while on orbit to minimise the risk of orbital debris, so you would expect the chance of impact to be small. Still I would have thought if there is a chance an analysis would have been done.
Come on! You're NASA for Christ's sake! You're the ones who come up with this shit! Why I bet you have a bunch of guys sitting around somewhere right now just thinking shit up, and somebody backing them up.
IANABS (I Am Not A Brain Surgeon) so I'll leave the analogising to you in this case, however;

"That's like saying my cars will go faster when the weakest cylinders are removed. Total horsepower goes down. But, I'll grant you, you'll get a better horsepower/weight ratio for your engine/brain."
I was merely pointing out that you would not recieve a better power-to-weight ratio which i think i have shown. Thanks
I'll start by wishing you the best of luck removing those two cylinders.
As I have experienced my automotive engineering degree so far and from what I have observed during my work with a FormulaStudent team, the power-to-weight ratio most commonly refers to the power produced by the engine over the net weight of the entire vehicle. Nontheless I think you will find the reduction in engine weight would not offset the larger weight of the vehicle alongside the reduction in power.
Start with a vehicle of curb weight 2000kg and assuming an engine weight of 200kg. Producing 600bhp this vehicle would have a power-to-weight ratio of 0.3
To find the reduced weight vehicle PWR.
Find 33% of the engine weight and subtract from the net vehicle weight. This makes our vehicle 1967kg. Now our vehicle produces 450bhp and the resultant power-to-weight ratio is 0.228.
A quick comparison of these two numbers 0.3 and 0.228, leads me to belive the engine with the dissapearing cylinders would have a weaker PWR as I origianlly stated.

If the general public aren't allowed to view certain laws who is exactly?
I think the problem is the majority of the non-tin-foil hat wearers wouldn't be able to tell you why it's a bad thing.

Actually that would give a lower hp/weight ratio, I think you mean greater hp/litre ratio. I believe the hp/braincell ratio still stands though.
