Mighty Mice return from Space
Genetically enhanced mice were on ISS since December 8th as a part of scientific experiment. The mice were donated by the nonprofit Jackson Laboratory in Maine. They were genetically modified for muscle growth to experiment the zero gravity effects on human body.
During long term space flights, Some astronauts have experienced bone and muscle loss. Experiments like this can help to understand how to manage these kind of problems. Researchers believe that these kind of experiments can help to prevent muscle and brain loss during missions and to help with recovery efforts after the astronauts return to earth.
These mice have a muscle mass of two times compared to average mice, so they are called the “Mighty Mice”. 40 female mice were sent to the space station. They will be compared with 40 normal female mice (Unaltered) on earth as a control.
The research knowledge is also to be applied on future Mars and Moon missions.
