Err...

“Probably the silliest design of all time is the Star Trek ‘Enterprise’. It's obviously built with a clear notion of which way should be ‘up’ - but what does up or down mean in space? Why make the habitat section in the form of a saucer, anyway (except, perhaps, as homage to the old Kenneth-Arnold style UFO shape)? And, since the engines are so far off the centreline, why doesn't it only fly in loops?”

None of this makes sense. Of course you have to design a spaceship with a notion of which way is "up", if they have gravity and rooms inside them designed with a similar assumption in mind. And the engines aren't rockets. Seriously, I don't care about this stuff enough to make a career out of it, but the guy who does seems to be talking some crap!

Fail yourself.

If the gravity is artificially generated (I certainly don't remember Enterprise spinning rapidly around its axis in flight) then there's no reason it can't be in different directions in different parts of the ship, so there's no reason for it to be in one constant direction that could be called "up"; radially outward from the center would make as much sense.

Also, the impulse engines certainly are reaction-mass-based rockets even if the warp drive isn't.

I always thought that there was a galactic 'Up' because whenever the Enterprise encounters another ship, they're always aligned along the Z axis.

The Enterprise looks cool and is the right shape for a pizza-cutter.

If shape doesn't matter then why not?

Maybe it's psychologically important for people to have an idea of 'up'.

I'm not sure about the other classifications but the NCC-1701D certainly had it's impulse engines affixed to the saucer section. The warp nacelles don't provide thrust as such, they just create a warp field.

That's why the impulse engines are based in the "neck" of the craft at the rear of the dish - least the model of the Enterprise-B that I had made as a child did.

Also whilst it'd be possible to put the artificial gravity plates in all manner of configuration (possibly, they may conflict with each other) just think what a pain in the arse it would be to navigate the ship, one minute you'd be on the floor than walking up a wall to across the ceiling - it would disorientate the common passenger which lets not forget is a position space travel is in by the time Star Trek is set.

Also the article mocks some space craft for there aerodynamic designs - such as a bird of prey, but a bird of prey is capable of atmospheric landing to which point aircraft aerodynamics come into play - just look at our own (now consigned to the dustbin of time) spacecraft - the shuttle.

All this just goes to show - you will still get people bickering about your starcraft design as much as your hacking depiction as, even though we've no authority, it's never held us back before :D

Re: Fail yourself

"then there's no reason it can't be in different directions in different parts of the ship, so there's no reason for it to be in one constant direction that could be called "up""

Yes, it can be in different directions in a ship designed by a drug abusing fashion designer. In an interstellar battleship you want your crew to know where their up and down are. You also don't need the extra stresses due to gravity gradients between different parts of the ship when you have to think about dealing with photon torpedo impacts.

Facepalm

Such a clear notion of up that it's actually down.

IIRC, it was originally designed with the engineering nacelle above the saucer and the warp nacelles at the bottom. Roddenberry said it looked better upside-down and that's what we got.

There was some blurb as to the rational of the design of the Enterprise (justifying it after the model was made, perhaps, or this is what they thought of when designing the ship - I'm not sure and I don't have the book with the background anywhere near me.)

Warp engines were kept separate from the main body due to radiation. Most Star Trek ships kept to this design. This did change later on (The Bird of Prey from the films) but for the TV series it was mostly adhered to. The saucer of a Federation ship was intended to detach, both to operate independently, and to allow atmospheric landing. ST:NG used this quite a few times, but the original series and the films also referenced this technology. It was not unique to the Federation, either: The Klingon ships were supposed to be able to detach the front and back of their ships, too, for similar reasons.

As to why there is an 'up': In battle you need to have a clear reference as to where an enemy ship is in relation to you. So, starboard twenty degrees would be twenty degrees from your axis to the right. But up or down? Well, Positive ten degrees would tell you that, wouldn't it? And you can only do this if you have a standard reference plane to work from. And if you're doing that, why not set gravity to that standard plane? As to points where artificial gravity might intersect: You'd get Lagrange points within your ship: Points of zero gravity. These have appeared in other films and series where they have explored such concepts before (I remember seeing it, but can't remember where...)

But the main reason why all these ships look so outlandish is so people can recognise them. You need to know which are the good guys and which are the bad, and you need to know which series or film you're watching just by seeing the ship designs. I guess they learned their lessons from the old B-movies: You could watch those and see the same ships used, and the same space battle scenes used time and again (Battle Beyond the Stars, Star Chaser, Star Crash... just to name a few).

Galactic Up

The ship's computer works out which way up is by aligning itself with the planetary system its in. The computer also works out where the planets would be so they don't warp miles away from their target.

Agreed

The Star Trek designs are some of the most beautiful and inspiring examples of futuristic spacecraft platforms. There actually is an Up in free space, which is aligned to the galactic plane. That plane is what provides the coordinate system relative to the numerical vectors that are so often referred to during vessel manœuvres.

Different directions??

The Enterprise doesn't spin. The shape is against it. Setting up a vessel with an internal gravitational geometry that varied from point to point would be asking for broken legs and other injuries in the crew. Then too, since the "gravity" is artificial, there's no reason to assume a point source that creates a radially symmetric field either. From the view point of the health and safety of the crew in a long duration voyage, a stable "up" is a reasonable decision. There are plenty of screwy things in the "design" of the Enterprise, but I don't see gravity as one.

Its a bit dull for Hollywood

but the 'big sphere' pops up in various places... Battletech dropships and the Adamist ships in the Night's Dawn series (and I guess any other books that might have been set in the same universe) spring to mind.

I thought a more interesting design was the long pointy wedge of Alastair Reynold's Lighthuggers... if you're going seriously fast, streamlining is still a benefit even in the interstellar vacuum. You get to make something that looks cool and is yet still practical; what's not to like?

There have been a couple of giant spheres. The Borg Queen's ship in Star Trek: TNG and my favourite (ship that is, not film - I'll always prefer the books to the TV and film outings), the Heart of Gold from The Hitchhiker's Guide to the Galaxy movie.

The big advantage of a sphere

is it has minimal surface area. If you are trying to minimise bleeding internal energy into space, pointy bits are not optimal.

Possibly a sphere with retractable sticky-out heat sinks for temperature regulation.

Yep

Assuming that the ship has to contain an atmosphere of some sort then the sphere makes good sense. Then, if there is any sort of radiation hazard from the engines a 10KM open frame pylon with the engine at the other end...

And we are back to 2001.

"The long pointy wedge of Alastair Reynold's Lighthuggers"

While this may be pretty coolish, I imagine a hydrogen atoms coming at you at 0.99999 c is not going to be seriously hindered by the wedge while it deposits its energy into the machinery and soft tissue.

Better use a Bussard Ramjet with FRACKING HUGE MAGNETIC FIELDS GENERATED USING MONOPOLES or better yet a kilometer or so of asteroid between you and any onrushing crap. Like in "Pushing Ice".

No Nuclear BBQ icon? Tsar Bomba, then.

EE Smith used a giant sphere for the earlier ships in the lensman stories - not on film - as did AE van Vogt whose "Scarlet Destroyer" was clearly the direct ancestor of "Alien." All in all though, spheres are boring.

I was going to trot that one out.

They moved to teardrops as EE Smith's inertialess field plus thruster drive system gave the interesting effect of streamlining being an advantage in space.

When you do away with the pesky lightspeed limitation, how fast you go is a product of thrust vs. the resistance of the little matter floating around in interstellar space. Wall shields dealt with the fact that his ships were effecively barging their way through interstellar hydrogen all the time. Intergalactic travel was practical (if that's the right word in this context) due to the lower density of crud between galaxies.

Shielding

"or better yet a kilometer or so of asteroid between you and any onrushing crap"

Yes - you'll want some damn good shielding in front of you. Even the "FRACKING HUGE MAGNETIC FIELDS" of a ramjet won't be much help against larger, neutral-charge debris. And there's no point in making that shield look pretty - it's going to get banged up anyway - so might as well just grab a handy piece of space rock.

On the other hand, we already have a pretty nice spacegoing environment with decent shielding, earth-like conditions (including gravity), and lots of cargo space - the Earth. One of Larry Niven's space-travel proposals was to turn the sun into a ramjet and just move the whole solar system around. (Sun moves, drags planets gravitationally - which also spreads the acceleration out nicely.) By the time you've used up a significant amount of the sun's mass, you should be able to replace it with interstellar hydrogen using your magnetic scoop.

(This does require some kind of magic tech - Niven suggests "cheap transmutation" for refashioning Jupiter's mass - to build the magnets, so it's basically fantasy.)

Of course you can't go into orbit around an interesting extrasolar planet; but you can park (well, match velocities and angular accelerations, within necessary tolerance) relatively close to one - just far enough out not to perturb orbits too much - and use conventional spacecraft to visit, if you must. At least it becomes an intrasolar-scale journey.

I thought the wedge shape was simply for reducing the lighthugger's cross section. There also was a thick coating of water ice for ablative armour. (I don't remember any magnetic shielding, but it wouldn't surprise me.)

Aerodynamic...

Of course if a space ship confines itself to space and planetary bodies without atmospheres they do not have to be aerodynamic. However, short of some magical property that allows spacecraft entering a planet's atmosphere to avoid the normal laws of aerodynamic, it would seem rather sensible to make them work well in that environment. After all, the Space Shuttle was so designed as were the re-entry capsules for manned missions using disposable rockets. So the alien's choice of an aerodynamic saucer shape might appear quite sensible, albeit unnecessary for the mother ship which is presumably sitting out beyond the atmosphere.

It's notable that Arthur C Clarke (who cared about such things) had the Discovery 1 as a functional, deep-space design and not an aerodynamic one.

Incidentally, Prof Brian Cox once acted as an adviser on a Sci Fi film, and he noted that one thing which always had to be included was sound effects in a vacuum. Space battles simply don't seem to be convincing without those.

Ooh! Yes, those sound effects as Blake crawled along between the outer skin and the passenger areas of the prison ship whilst a space battle raged outside. That was creepy.

Though it was the lack of sound effects during the sequences outside the ship that made 2001 so convincing.

That's the point that Krauss makes though

None of the saucers mentioned in the article have motherships, they're the actual deep space vehicles. It makes no sense to design a deep-space vehicle to behave well in an atmosphere.

"However, short of some magical property that allows spacecraft entering a planet's atmosphere to avoid the normal laws of aerodynamic"

There's generally so many laws of physics ignored when people get onto the topic of alien spacecraft or future spacecraft in the media, what's a few more?

If you can travel between the stars, stopping and entering an atmosphere at a speed where aerodynamics are of trivial importance should be small beer.

The only reason for being streamlined is if either a) you want to use the atmosphere to slow down with bits melting off the outside or b) if you need to travel quickly in an atmosphere and can't be arsed to generate a field to permit this (e.g. like the Theron flying houses in Dan Dare).
