Why NASA Is Blasting Water Bears And Bobtail Squid Into Space (npr.org) 34
NASA is sending water bears and bobtail squid to the International Space Station, "as NASA researchers attempt to learn more about how the conditions of spaceflight can affect biological organisms and, by extension, future astronauts," writes Joe Hernandez via NPR. From the report: Tardigrades are microscopic organisms better known as "water bears" because of their shape and the fact that they commonly live in the water. (They have also been called, endearingly, "moss piglets.") Water bears can survive in conditions that would prove fatal for most other animals, such as exposure to extreme temperatures, pressure, and radiation. The fact that they are basically indestructible, according to NASA, makes them the perfect test subjects for an experiment about the effects of spaceflight on biological survival.
Thousands of microbes live inside the human body and work to keep us healthy. But scientists don't have a clear picture of how microgravity -- which allows the kind of floating weightlessness experienced by astronauts when they travel into space -- affects those microbes. That is the subject of an ongoing NASA research program called the Understanding of Microgravity on Animal-Microbe Interactions, or UMAMI. Scientists will study whether microgravity has an impact on the relationship between newly hatched bobtail squid, or Euprymna scolopes, and their symbiotic bacterium, Vibrio fischeri. The goal is to use what they learn about the relationship between squid and the microbes to help better prepare astronauts for lengthy space missions and preserve their health while they're out there.

Why tardigrades and squid? (Score:4, Interesting)
Human bodies play host to neither squid nor tardigrades. Er, normally. Shouldn't they be taking samples of common flora that reside in the human body and testing them directly to see how well they survive in 0g conditions?

You're thinking way too logically. We're probably still three or four "create jobs" flights away before we get to that boring phase where we're actually justifying budgets with valid studies.

. . . yeah, figures. Also I should have said "fauna" but at this point, who cares? NASA doesn't.

Hmm. Really? Well I'm not going to argue the flora vs. fauna thing.
I was rather thinking of, instead of monitoring a culture of e.coli (or other bacteria), trying to simulate a host environment for them and see how they fare versus in a similar contraption on Earth over the same time period. Something like a Human Gastric Simulator (HGS). Though you'd need to simulate the intestines as well.

Even TFS explains that. The reason they are taking the water bears has nothing to do with human micro-biome. The reason they are taking the squid is to study the symbiotic flora of the squid.

After all, don't you need space tardigrades in order to help navigate the space mushroom mycelial network so you can travel across space really quickly? [wikipedia.org]
At least, until you figure out how to modify your DNA so you can return the space tardigrade back into space...
But we have to start somewhere. And let's make sure we don't lose the technology by sending it 1000 years into the future.
