NASA has confirmed that its location of rodents provides for the possibility of conducting significant long-term biological research at the ISS. Rodents, deployed for a space experiment, even learned to neglect microgravity. ( April Ronca | YouTube )
Earth mice sent by NASA to the International Space Station quickly adapted to space missions. Scouts even learned to resist microgravity
Space mice sent to the ISS would do all that ordinary mice do in the house: feeding, grooming, clustering and interaction with other mice. During the entire period of their experimental space flight, mice also learned to move in zero gravity
These behavior of cosmic rodents have been described in detail in a recent study published by NASA's Ames Research Center. Behavioral analysis can reveal how animals adapt to the cosmic environment, and as other changes in physical activity, feeding, alcohol use, circadian shifts, and social interactions can change other experimental activities. space flight environment during expanded missions and similarity in response to the astronaut's crew.

Their habitat was a cell specifically designed for an experiment that investigated how space and microgravity affect the models of organisms whose biology has similarities with the systems of the human body.
In general, the mouse behaved normally and
Denied the microgravity
The video showed that during the second day of their stay in the orbit of the mouse began to adapt to microgravity during normal activities. Mice were observed using a locomotive like hindlimbing, and they also used a pulse to swim to their destination.
A week after launch some mice showed a unique behavior. The younger were more physically active than their older colleagues.
As shown in the NASA video, on the 11th day of its space flight, the mice ran and persecute each other inside the habitat. Their movements were almost like floating, indicating no weight in space. Their behavior of "race tracking" has even grown into group activity.
The clip also showed the mouse on the other side, rotating in a position for food, and another mouse used its tail to balance and capture food. Another rodent grabbed a cup inside the body with the help of the back paw to balance itself.
"Rodents quickly adapted to their new, unimportant circumstances, for example, having secured themselves behind the walls of the habitat with hind limbs or tails and pulled out this body. This posture was similar to the mice on Earth standing on their hind legs to explore their environment , – says researcher at the NASA Research Center "Ames" and lead author of the article by Anna Ronka
