Ask Slashdot: Technical Advice For a (Fictional) Space Mission?
An anonymous reader writes "I'm just starting to put together the pieces for a fictional story about a space mission. To put it briefly, I would like to give believability to the story: probably set a few years ahead, just enough for the launching of the first colony in the solar system, but with the known challenges posed by the current technology. Is anyone up for a little technical advice on space travel? A few quick questions: As for the destination, the moon and Mars are the obvious choices, but what else would make sense? How long would it take to get there? What could be the goals of the mission? Any events or tasks that could punctuate an otherwise predictably boring long trip? Any possible sightseeing for beautiful VFX shots? What would be the crew?"

If you're looking for technical advice on space flight I would recommend you check out the Orbiter forums. They are the boards for the Orbiter Space Flight simulator. It may be a simulator, but is built to be extremely realistic. You can find a lot of very knowledgeable people on the boards that would probably tell you exactly what you wanted to know. http://orbiter-forum.com/
Since most of the replies so far have either been disparaging or been references to other scifi works, I will do my best to actually answer your question.
For the sake of accuracy, I am going to assume the following:
The mission is 1 way.
There will be no resupply operations.
The colony must supply itself with infrastructue and supplies.
That out of the way, here it goes.
First, your crew must be over 500 people, and totally unrelated to each other. This is the bare minimum required for a stable breeding population. Any smaller, and you end up with an unviable population, a la the nazi eugenics colony experiments.
Your crew cannot all be officers, administration, tech heads, et al. You positively have to include blue collar workers. Machinists, assembly workers, etc.
In addition to this, you cannot presume to find food on the planet you are sending the colony ship to. At our distance from the nearest goldilocks planet, we can't even get a gross atmospheric spectrograph, let alone a detailed list of possible lifeforms. This means you have to not only take whatever food your mission needs for the trip through space, but also the means to produce food when you get there. Frozen domesticated animal embryos, collections of edible seeds and plantforms, etc. The works. It also means you have to take horticultural experts and farmers with you.
In addition, there is a lot that can go wrong on such a mission. The colony ship will be in transit for over a hundred years to reach the nearest starsystem using the fastest possible forms of propulsion currently available to us. This *will* be a multigeneration voyage, and shit breaks. You have to be able to fix things and make spare parts. That means you need a complete factory and refinery complex built into the colony ship.
In short, think of a space vessel with the combined cubic footage of new york state, comprising manufacturing, housing, environmental, and food cultivation systems, in addition to propulsion, power generation, water reclamation, and administration systems. You will be launching a small country into space. If it isn't at time of launch, it will be by the time it reaches its destination.
The colony ship will be too large to land on the destination planet. It will need small craft to deposit transplanted lifeforms, colony site construction equipment and supplies, and ground personel on the surface. These craft need to be reusable. The colony ship would BE the supply line for the new planetary colony site. It would stay in orbit, produce and deploy any gps or com system satelite networks, and ensure the viability of the ground based colony as it develops.
In addition to the lander craft, the colony ship would need service and resourcing craft to help keep the colony ship operational. The ship would be too large for unassisted spacewalks for repairs, so some form of space only maintenance and cargo tug craft would be necessary as well.
This means the colony ship needs cargo bays, and docking bays, distributed around the ship.
Due to the size of the ship, some form of internal rapid transit system for the crew will be necessary.
The psychological integrity of the hermetically bottled colony ship population needs to be maintained. Recreational fascilities need to be available, including botanical gardens which serve no other purpose. (This means you need people to maintain them. Some bit of crossover in functionality can be possible with the horticultural experts developing new domestic plant varieties enroute in the botanical gardens.) It needs musicians, artists, poets, movie stars... the works.
The colony ship has to contain epic shittons of water and biomass. It has to be able to reliably handle a growing population while in transit without overloading the environmental systems. It also has to be able to deflect cosmic energy for hundreds of years.
The colony ship has to produce artificial gravity. This means it has to rotate in some fashion, as no other means of simulating gravity is currently known.
If you are going to write a story about such a voyage, you have to explain how the earth managed to fund such an operation, and also why they did it.
In fact, make the crew all women, except for a single man who's cryogenically frozen. When the VCR clock malfunctions they in desperation thaw him to fix it. He does, and after that, you can imagine! Va-va-voom baby!
If you want to make the story really believable.
