He was a pretty fishy fish!
The Japanese Space Agency (JAXA) has sent an aquarium to the International Space Station. It’s not for relaxation, mind: the fish tank will be used to see how microgravity impacts marine life, including a transparent fish.
The Aquatic Habitat, or AQH, was sent to the space station on 20 July, with the third Japanese H-II Transfer Vehicle. It will reside in the Japanese Experiment Module (JEM), and uses LED lights to simulate day and night cycles.
First up, researchers plan to examine the Medaka (Oryzias latipes) fish, and look at the impacts of radiation, bone degradation, muscle atrophy, and developmental biology.
