What an intergalactic spaceship would need....

[escyos]

ive been doing a lot of ....well nothing lately and ive been thinking about spacecraft in stargate.

Most of them have things like shield generators, hyperdrive, cloak etc...but what else would ships have to have:

1. Life support systems
2. Damage control systems
3. Sensors (radar? does that work in space)

what else?

[Gregorius]

- Engineers and mechanics to keep it running.
- Food.

Radar would probably work in space seeing as it's in the EM-spectrum and works with rebounding "waves" of an object (It's kinda like sonar, but with EM waves instead of sound). It's also used on satelites to take measurements of the Earth.

[wise one]

navigation computer
food
defensive weapons
sensors
movement

[Rasunda]

A hull
Manuvering thrusters
Comunications(subspace/intercom)

[lordofseas]

A crew.

A spaceship does not need to have the energy source (e.g. star light) or the propellant on board (e.g. solar sails). It doesn't need a crew on board in the stargate world, they could always just stick a gate on it. It doesn't even need life support, they could just use it to ferry through puddle jumpers. It doesn't need a computer, because all you would need to do is point it in the right direction and just have it naturally stop. In fact you don't need a ship or shields or weapons. The Asurian gate-cannon was just a gate, a computer and a hyperdrive. All the computer needed to do was keep track of time, turn off the hyperdrive and switch on the gate, a simple timer-switch could do that. As long as a gate can withstand re-entry, all you need to do is fire a gate at a planet. Stick a DHD on it and it can auto-update its position and you can fly out of it at any point during the journey. So in conclusion, a gate+dhd is all you need for a ship.

and a hyperdrive.

use a supergate. even better.

Don't forget the bathroom. possibly lifepods of some sort and a TV

[Gregorius]

Captain Jean-Luc Picard of the USS Enterprise, to command the ship.

It would also need recycling facilities to recycle urine and waste water back into drinking water.

[escyos]

i was thinking more of what would be possibly in OUR universe right now...so hyperdrive, stargate, supergate, subspace communications and Picard are out!

How big a ship and what size the crew for an intergalactic mission?
What professions should there be?
What kind of weapons (possible weapons, so no asgard beams)?
What will power it?
What will it be called (no, Enterprise, Destiny, Prometheus, Apollo, Daedalus, Korolev, Sun Tzu, General Hammond, Odyssey, O'Neill, Daniel Jackson or other)? Would we use an ancient Greek or Roman god name?
What will it be made of?

Well depending on what it purpose it would need propotional sze. If it was Legacy ship that can transport thousands of people across the galaxie over a few decades it would need to be very very large as to be able to support continues life. In fact it might need o be like a Raman cylinder from Arthur C Clarkes Rendevous with Rama.

Well intergalactic means between galaxies, so that's going to take millions of years. If humans are going, then you basically need a society of around a few thousand at least (for the gene pool). Hydroponic systems and plants. A water recycling system. A ventilation system (the plants can scrub the co2). A very thick hull with a hull-air layering structure. You don't need an engine if you plan to get there on inertia and gravitational sling-shots only, but you would have to meticulously plan the flight path. You would also have to limit the number of diseases that are taken on board. No animals should be taken on, it would drastically increase the size of the ship and the number of plants needed while also posing a risk of cross-species diseases which are the real killers. Due to the lack of gravity, the change in diet, daily life, sunlight, vitamins and minerals and environmental conditions and the possibility of degradation of the radiation shielding leading to increases in background radiation, the people at the other end would have short stubby limbs but hand-like feet and would be suited to a zero G environment, a low-calorie vegetarian diet and low oxygen levels. The humans that got off the other end would not be humans and would not be capable of living on the intended planet. There are very few jobs that would need to be done, keeping the plants alive, the vents working, the generator going (which should be human/body-heat powered) and patching up any possible hull leaks. Although it may be best to simple sacrifice a breached section, also a breach would change the inertia of the ship enough to miss the target.

In fact, the simplest form of a viable spaceship is a large geologically active rocky planet with an atmosphere and ionosphere. The food chain can rely off of the geothermal vents instead of the Sun. Just point the Earth at the place where you'll eventually cross paths with the planet you want to get to and give the Earth a push, simple.

interstellar then

FORGETTING the fact that distance is too far for our lifetime
say if we had the ability to get to other planets in our system at a reasonable time say a few days instead of 6 months..oh and we had to fight off space pirates/goats.

They always seem to leave these out.

Firing weapons in space is only a good idea if you're trying to run away because all weapon launches are also rocket firings do to the 'equal and opposite force' rule. As long as they have enough air/food/water for the trip, you can just throw them. An EVA spacesuit is actually an independent spaceship. Give the guy water, food and air, or recyclers for those things and he's golden. If you want him to also be able to steer and fight, give him a bag of stuff, anything will do, he can just chuck it at someone as a weapon and chuck it in the opposite direction as a rocket. He'll need a thick hull to survive impacts, radiation and re-entry but as long as he's planned his trip correctly he should make it.

The difficulty in space travel are keeping the crew alive long enough and making sure you're going in the right direction. Claire from Heroes could be used effectively as a spaceship because she won't die.
