    Anyways, one of the special activities we did was a mock Moon base mission. Basically we spent one day cutting black garbage bags open and duct taping them together into a series of domes and tunnels for our "base". It had two openings: one was a sealable flap (our "airlock") and the other was an open hole that they put a big fan in to inflate the entire structure (worked really well too). Oh and some small ventillation holes in each room. Anyways, the next day we went on our "mission", which was basically a dozen or more of us stuck inside this inflated garbage bag, in the middle of a gymnasium with the lights turned off. We were divided up into teams and everyone given certain tasks. I was a communications officer, which basically ment I got to sit there and communicate with "earth" (our supervisors) on an old macintosh. We were also responsible for general coordination of the base. Another team was our Medical branch. They had some generic tests/experiments to try while we were 'on the moon', in addition to being responsible for the health of the entire staff. Theirs was actually the only 'serious' mission, because they had to test everyone regularly for signs of CO2 poisioning while we were effectively trapped inside a plastic bag for six hours straight. We also had an exploration team that got to do "moonwalks", which was basically tying a rope around one guy, blindfolding him, and shoving him out into the gymnasium to see what he could find. They came in very important (more later). The only other team I remember was our "Engineering" team, who was responsible for maintaining the base's structure, armed with nothing but some spare garbage bags, some knives, and enough duct tape to wrap an army. They even got around to making a couple of small additions to the base. Those guys had lots of fun.

    The cool thing about our "mission" was, in addition to trying to complete the tasks given to us by Earth base, our supervisors fucked with us at every possible opportunity. They did shit like "solar activity disrupting communications" (disconnected our Mac from the LAN) so we were on our own for an hour. They walked around with knives and poked holes in the bags to keep the engineering team busy... VERY busy. When we were done, our base looked like someone had taken a piece of swiss cheese and put tape over all the holes. They were cruel. About 20 minutes after our engineering team completed a tunnel connecting medical to communications, I hear this slicing sound and feel air rushing past my face. I turn around, and the bastards had cut a three foot gap in the new tunnel! Engineering runs over and starts trying to tape it up, but its not gonna be airtight... so the creative bastards rip off their paper medical jumpsuits (we even had mission stickers, names, rank, etc on them) and use them to seal off the tunnel. Heh that was cool. Even cooler though, was when the "alien" got into our base through the same gap. One of the engineering guys opened up the tunnel to see about further repairs, and he finds the supervisors have slashed it (AGAIN!) and dumped a plastic turtle in the gap as an "alien". The whole base erupts in panic. Engineering shows up in force as they're the only ones with knives. Medical runs in and tries to start bossing people around because "this is a biological matter". It was hillarious. We eventually figured out (with Earth's help) that the alien was dead, and medical got the goahead to start an autopsy on it. Very cool.

    It turns out that if you're only going out for a couple of weeks, or if you have a significant mass budget, recycling isn't important at all. The mass of food consumed is surprisingly low, and we have plenty of experience keeping it light and compact (think "MRE"s; the military has a vested interest in food that keeps and is easy to transport). Oxygen consumed will at most be enough to burn that food - the part of that food that's not already oxidized (water-based). Water consumption is relatively low - a couple of litres per day for a comfortable allocation. So you have a few pounds of supplies used per day, and can easily store a year or more's supplies without the supplies outweighing the rest of your expedition's equipment.

    For recycling, air and water are the most important. Water because you go through a significant amount of it, but it's still fairly easy to recycle, and air because you go through a _lot_ of it (2-3 times the dry weight of your food). Both of these turn out to be easy to do if you have _power_. Brute force chemical processes and (for water) techniques like distillation come to the rescue. While 100% recycling of water is hard to do, even 80-90% would have a huge impact on your supply mass, and air recycling is very nearly perfect.

    A biologically based recycler has the advantage of being able to turn solid waste into food, but that's about its only advantage. System efficiency vs. energy in (light) is actually pretty poor, and it takes a lot of space and a lot of mass, even if you use something like algae that's near the bottom of the food chain and has low infrastructure requirements.

    Biological recyclers are useful when you can afford a large facility mass, and when you have a lot of people to feed. These are true on a large space station (think "colony") or planetary base (again think "colony"), but not for most spacecraft.

    Still very interesting to think through the options for.

  33. Re:Where's the robot? by flechette_indigo · · Score: 2, Interesting

    I think it'd be alot simpler than a lander-rover. No gravity or atmosphere-entry to contend with.

    Here's the scenario. I'm I'm totally ripping off Larry Niven Here.

    Assuming that we can find an asteroid with the desired consistancy and orbit we'd need the following operations to be performed:

    Make big curved mirror: Blow up balloon. Spray foam over it. Puff a little vaporized silver inside it. Cut it in half.

    So you got big big heater/cutters now.

    Drill the asteroid.
    Throw in a chunk of ice (gotten off a neighboring asteroid, sealed within a big prefab exploding can).
    seal the hole.
    Melt the asteroid into a big molten ball
    explode the can.
    Let bubble cool.
    Drill hole.
    Slap in prefab airlock..
    throw in more ice.
    Heat it up to 72 degrees or whatever.
    Electralysize some of the water for atmosphere.
    grind up some of the rock for soil.
    Innoculate the soil...

    ok, maybe it is kind of involved.

    How about just a power station ( temperature-differential generators? ) and a pile of refined minerals. It'd be a nice step. You'd melt the ball (no exploding can)and spin it. When it cools you got refined strata.

    So now the robot's gotta:
    Fling out a sheet of electricity-making fabric/grid/whatever.
    Blow up a balloon, spray foam over it (maybe the balloon could handle this itsellf), squirt the silver.
    Cut it (again, maybe the balloon. Maybe the mirrors could make themselves).
    Spin the asteroid (ion rocket-pack?).
    Aim the mirrors.
    (Could the robot process molten metal into thousands of miles of wires for the generator? Controlled-splash it? Vaporize it and spin it on magnetic fields?)

    Would this power-station / resource-dump be feasable?

  34. last time round... by pvanheus · · Score: 2, Insightful

    From the CNN article: "Polyakov told Interfax reporters that the 500 Days experiment will not include female volunteers."

    I wonder if this is related to what happened last time they tried something like this. From space.com:

    "Canadian physician, Dr. Judith Lapierre, tells a different tale. She was in the chamber for 110 days. "Somebody pulled me by my arm and tried to kiss me. Of course, we are not talking about [rape], but for me it was a high level of sexual harassment and if women don't stand up, the next thing that happens is usually that. I pushed the guy, but then I was told that in Russia I just should just give him a slap in the face. However, it is not my way of handling such things.""

    If this (sexual harassment problems) is their reasoning behind the decision to exclude women, I think its a pretty poor reason. Why not rather exclude men?

    Think about it - all these Big Brother shows where they lock up people for a year in a container really do simulate the social and psychological aspects of a mars mission.
