Space Fish: ISS Aquatic Habitat Delivered By HTV-3
astroengine writes "Yes, it's the moment we've all (secretly) been waiting for: Fish In Space! 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."
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.
The enemy's gate is down.
