We welcomed a new laboratory rack in our increment, the fluids integrated rack, for doing fluid physics in space. Space is an incredible place to do research because it is an environment where there's no sedimentation, no convection, no diffusion, and no buoyancy.
We also do quite a bit of plant biology from Russia, Japan, and Canada. One day we expect to incorporate plants into the life support systems for the vehicles that go to Mars. Through the process of photosynthesis, plants produce oxygen, scrub carbon dioxide out of the air, and clean up our wastewater, so learning how to grow plants in space--such as lettuce, as shown here by Roman--is very important.
We also had an experiment from the University of New Brunswick in Fredericton. These are willow trees from New Brunswick that we flew up, trying to understand why reaction wood forms. Reaction wood makes poor lumber, so we're trying to improve lumber production in New Brunswick.
Koichi mentioned stowage of urine and blood samples. This is where we stow it, in a -80 degrees Celsius freezer.
