Space Fish: ISS Aquatic Habitat Delivered By HTV-3 68

But before you go getting too excited and start asking the big questions — like: if there's a bubble in a microgravity aquarium, what happens if the fish falls into it? Let's ponder that for a minute... — it's worth pointing out that the fish aren't actually in space right now (their habitat has just been delivered to the space station by the unmanned Japanese H-II Transfer Vehicle 'Kounotori 3') and this fishy experiment isn't just to see how fish enjoy swimming upside down, there's some serious science behind it."

  • I would love to learn more about how Fish can live in space and even what changes will need to be made for a tank to work in space. This is a new experament idea and one I am very interested in seeing explored and seeing how it turns out.

      Not that new...this experiment is derived from one flown on the Shuttle a few times already. This is mostly an extension of the previous research. What I am really interested in is the egg-to-egg possibility--the system is designed to support up to three generations of fish, so they will be able to observe whether zero-gravity causes intergenerational changes (eg., whether the children of those born in zero-g are as fit as those born of one-g fish, or as one-g fish themselves). This is a significant challenge for any possibility of space colonization, so experimentation in it is quite welcome.

      I would love to learn more about how Fish can live in space and even what changes will need to be made for their tool using habits. Also, I would like to see their mathematical formulas postulating fish advancement in the 21st century. We'd be better off with pigs in space.

    Sound should be able to push bubbles around to prevent build-up of large bubbles.
    The only problem then would be the fish spazzing out at the sound waves.
    So grid to constantly cycle the water around in a twist to eliminate will probably be the other solution.

    Their solution sounds similar to the latter, but obviously far more complex than my simple example.
    I expected a sphere over a cuboid. Or even a cone. But hey, I am just guessing. They likely done hundreds of simulations to get the right system with the most space.

    Good luck to the experiment. Shall be interesting.

    Aquatic critters can be one link in a combined waste treatment / hydro-ponic growing system. I've heard that a cubic meter of sea water is the most prolific growing medium on earth. I'm interested in the downstream outcomes of science like this.

    Also am reminded of an old pulp sc-fi short story that took the form of letters between a Mars bio-dome colonist and the manufacturer of the living bio dome system... they kept adding critters to the dome to try and balance the eco-system, with predictable and silly results.

      I always remember what one of my biology professors said about these sort of biodome experiments: "life finds a way to live, unless it doesn't but either way, there is only one way to find out." What he meant was that those experiments should go on until they are so unbalanced that they threaten the human occupants with imminent death, but those without human occupants should be allowed to run until everything dies. The reason is that nature can surprise you with the way things adapt and you often learn t

The decayed plant matter in the habitat is making it a little funky, so after what begins as a polite correspondence with the support rep.. the lone colonist is told to add mushroom spores and as the situation deteriorates further, beetles (to eat the mushrooms), birds, a cat, a predatory hawk, a miniature deer and so on.. the tone of the letters gets increasingly manic as the habitat faun

    I hope that the next step after this is taking a cat into space in a properly-designed cage. (You don't want it loose!) Make sure that at least part of the cage is lined with something that the cat can grip so that it has the choice between clinging to the side of the cage and moving around in the inside and see how it adapts. Yes, I know that waste disposal will be a problem, but it's one that we'll have to solve sooner or later anyway.

    If you're worried about bubbles, then you probably don't understand the real problem: Fish remove dissolved oxygen and add carbon dioxide. On Earth, co2 finds its way to the surface of the water and mixes with regular air. In space, if you haven't solved the problem of getting dissolved co2 and fish poop out of the water, then you're just going to end up with a bunch of dead fish.

    The simplest solution is to set up a one-inlet, one-outlet filtration system: Fresh water and fish food comes in with nice fresh

  • Just for clarification, we have hardly been waiting for fish in space. Some of us saw them way back when. Getaway Special Payload G332 included the study of brine shrimp. This was a project from the a little high school in Houston called Booker T. Washington. In was developed in the early 80's and flew 1986. Colombia no less, and the last flight before Challenger.
  • On the tails of last year's discovery of "ocean like" water in comets [http://io9.com/5847004/comet-discovered-with-ocean+like-water-inside-of-it], this is a logical step. Should we not be looking for "habitable planets" but "habitable orbits"? Which, I suppose, would make every solar system habitable that had either a potentially deflected comet or a budget for fish aquariums ?

    On Earth, it's relatively simple to maintain an aquarium. In space... I hae no idea.
    Aquariums use several things:
    -Filters (impeller based canister filter will work in space.)
    -bubblers for dissolved gases.
    -food

    The biggest question for me, is how do you get good gasses in (O2, CO2 if a planted aqurium) and bad gasses out of the aquarium. On earth, the gasses interact with the surface. In space there is no surface. You can't just pump more gasses in without raising the pressure. What do you do with ammonia and
