Engineer Thinks We Could Build a Real Starship Enterprise In 20 Years 589
Nancy_A writes "An engineer has proposed — and outlined in meticulous detail — building a full-sized, ion-powered version of the starship Enterprise. The ship would be based on current technology, and would take about 20 years to construct, at a cost of roughly $1 trillion. 'We have the technological reach to build the first generation of the spaceship known as the USS Enterprise – so let's do it,' writes the curator of the Build The Enterprise website, who goes by the name of BTE-Dan."

An "Enterprise-type" starship is a misnomer at best. An ion drive to get to even the closest star would have to be a "generation" ship. It would take generations of people, born, liviing, dying, to reach the nearest stars.
The alternative would be some sort of 2001-type hibernation, which also would not be anything like the Enterprise.

As far back as the creation of a mass producible silicon transistor, the DoD funded that effort by Shockley to the tune of 15 million dollars (currently would have been 150 million dollars due to inflation of the last 60 years) to get the transistor that was built out of germanium into silicon so that it would be capable of being used in the guidance computers of missiles.

Imagine the military throwing 150 million dollars to create the transistor today, people would go ape shit crazy and call it a total waste of money, the members of Congress would try to make sure that the money was spent in their interests regardless if their locations was not ideal, due to manpower knowledge or otherwise. And in the end the transistor would be another wasted experiment to the tune of a few times the initial 150 million outlay.

They also envisioned a citizenry that was well trained in the martial arts at all levels and a very active component of the national military made up of state-level militias. Throughout most of American history, the national military was made up of a small core of a modest national army (usually about 30,000 soldiers during peacetime) supplemented with state organized regiments that would grow or shrink as needed. This continued until the end of World War II, when the national army started to dominate the state militias.
Standards of training, uniforms, and other "regulations" were to come from the national government (and is spelled out explicitly in the U.S. Constitution), but the idea was more of a highly trained citizenry more along how the Swiss Army is organized.
It is useful to know that Switzerland has been able to defend itself against much larger and more powerful countries, had two world wars rage all about them, yet never had to either capitulate to the demands of the major powers about them nor even get involved in any of those conflicts. Most citizens of Switzerland are armed (at least have weapons in their homes) because they are also members of that nation's military in some capacity, even though they are on "reserve status".
That was also the point of the 2nd Amendment in the U.S. Constitution, where armed citizens were expected to take the time to learn how to use weapons properly and there was even an assumption that nearly every citizens would take the time to go through at least some sort of military training. Even today I am a member of the "unorganized militia" in the state where I live (well... I was.... I'm a bit too old for that stuff now and the state constitution only requires people under 40 to be in that militia). Other states have similar clauses in their state constitutions and legal codes. How "organized" that "unorganized militia" actually can be is certainly subject to dispute, but it was never envisioned to have America be defenseless.

Additionally, medding by the DoD led to the requirement that the shuttle be capable of doing near-high-polar-orbit missions, leading to a lowering of cargo capacity (high-polar orbits can't take advantage of the equatorial boost of the earth's spin).

In other words, the whole Space Shuttle program is to me a total waste, where I can't think of a single thing that the Space Shuttle accomplished that the Saturn + Apollo vehicles could not have done except for bringing large object from space down to the Earth. Even that could have been done quite a bit cheaper with a purpose-designed vehicle made to fit on top of the Saturn V vehicle stack and didn't require a whole new launcher to be built.

That was 50% of his taxable income, which was a small fraction of his actual income. The remainder went to various partner companies world wide, for services that were frequently only on the paperwork.
I did work for a company who's CEO and CFO ignored the laws though. They created millions of dollars of imaginary money by floating invoices and payments. They convinced investors to buy in their company that was hugely profitable. On the books, it looked like millions. In reality, the company revenue was in the thousands.

The deduction was small, but I wanted to be truthful. I did drive two cars. If they compared the odometer reading from when I purchased them, to the current odometer reading, and I claimed I only drove on car, they would see the claim was wrong. In 2009 (I believe), the IRS garnered my wages for $3,000. That was the error they calculated because they denied the deduction for the second car. The error was only a few hundred dollars. The remainder was a penalty. My pay dropped to $300/mo, because the IRS was taking the rest directly from me.

I don't know.... America is throwing about $20 billion down a rathole call the SLS. If that same money was put toward building something like a 1:1 scale model of the USS Enterprise NCC 1701 in orbit, I would think it would be money better spent. At least in theory the money spent towards the SLS program is supposed to go into space anyway, so why not build a monument to government corruption that everybody can see rather than somebody touring the western desert of Utah?

More to the point, why on earth would you want to build a spaceship shaped like the Enterprise? It's not a particularly practical design for a spacecraft. It was picked for the show for exactly 3 reasons: 1) it looks like the ship from Forbidden Planet but with enough visual differences to avoid a lawsuit, 2) it looks cool and science-fictiony, 3) it fits in with all the fictional technology that it is fictionally loaded with (warp nacelles, deflector dish, etc). Assuming none of that stuff exists (and it doesn't), then don't make it that shape.
If what you want is a spaceship with ion engines and a rotating section with faux-gravity for pootling around the solar system, the best shape would not look like the Enterprise. If you must model it on something from fiction, the Discovery from 2001 is probably a better bet; but in reality it'll look much more pragmatically like the stuff we're building now.
Making it look like a prop from Star Trek is nothing but a nerdy wet dream.

An "Enterprise-type" starship is a misnomer at best. An ion drive to get to even the closest star would have to be a "generation" ship. It would take generations of people, born, liviing, dying, to reach the nearest stars.
The alternative would be some sort of 2001-type hibernation, which also would not be anything like the Enterprise.
"Beam me up Scottie, there's no intelligent life in this article."
Thanks to time-dilation as you approach the speed of light, if you can maintain 1G of acceleration, it doesn't take many generations of people to go to very far-flung places. You can travel 1500 light-years to the Orion Nebula in only 30 years of ship time. [daviddarling.info]. Of course 3000 years would have passed on earth by the time you get there. In just 60 years, you can travel 2 million light years. (which an observer on earth would see as 5 million years)
A 1G ship can also be thought of as a (one-way) time-machine. Step inside the ship for a big circular voyage and when you step out 30 years later, 3000 years will have passed on Earth.

Modulo the small problem of getting into orbit (Score:5, Insightful)
There is no doubt that in a situation of species-threatening emergency that mankind has, today, the technology to construct a quite large object in earth orbit and give it enough engine power to move through the solar system (Orion drive or whatever). The problem is that we do not have the technology to get stuff out of the Earth's gravity well with anything greater than 0.1% efficiency, and in the process of building that Enterprise-sized object we would destroy the Earth's atmosphere and ecosystem. So until a 10,000x better surface-to-orbit launch technology comes along this ain't gonna happen.

Re:Modulo the small problem of getting into orbit (Score:5, Informative)
NO, its not the first 100 miles, its the 10km/sec required to reach orbit. All of these "spaceship 1" type projects are nowhere near the delta-v required to reach orbit and this has caused a lot of confusion. Getting to 100 miles is relatively easy - the delta-V is below the exhaust velocity of chemical rockets so you don't need a huge mass ratio. The problem with orbit is that the delta-V is higher than a chemical propellant so the fuel / mass ratio of the rocket becomes large.
Earth to orbit is of course possible - we've been doing it for half a century, but its still expensive and difficult.

Ion engines don't provide significant thrust force, but they run continuously for a *very* long time, which is an ideal coupling with solar power and low launch weight.
A G, so it doesn't really matter.
If A ~ G, and you can run continuously anyway, then you don't need a spinning disk - whenever the engines are on, they define up and down for you.

This is nothing like the Enterprise except in shape -- and it would be pointless to duplicate the shape.
And besides, in the Enterprise world, dilithium crystals (with antimatter in there somewhere) were the power source of "reality", and "ion power" was what made Scottie get all wide-eyed.
With current technology, we'd end up with a generational sublight ship. Keeping in with the Star Trek theme, this would be closer to the SS Botany Bay [memory-alpha.org] which according to Star Trek canon was launched only 18 years ago. Of course, that turned out horribly wrong, so maybe it's not the mission to emulate.
Joking aside, making such a ship would be very neat. But the guy needs to stop pretending that it has anything to do with Star Trek or it's Enterprise. We could call it Enterprise if we wanted, but picking that shape would be silly -- there are much more practical shapes to be had. And considering just how expensive this would be, we should be trying to make it practical rather than novel.
