SpaceX and Their “Mighty Mice”

               With the incredible success of the most recent SpaceX launches this past summer, they have completed another study. This time, it involves an experiment to inject genetically engineered mice with drugs to prevent muscle mass loss when in space for a prolonged period. This experiment aimed to find better treatments to help avoid muscle loss, loss of bone density, and muscle fatigue for astronauts while in space.

               In Connecticut, a research lab sent 40 young female mice up in the space in December aboard a SpaceX rocket. However, eight of these mice were genetically engineered — dubbed “mighty mice,” and were also given certain protein-blocking drugs. Upon return, it was discovered that 24 of the control mice lost roughly 18% of their muscle mass while in zero gravity. However, the eight “mighty mice” sent up to space were comparable to the “mighty mice” that stayed on Earth. It was also found that some eight normal mice were given the “might mouse” treatment and had recovered their lost muscle faster than the others.

As far as results, all scientists were able to say this time was that specific molecules and signaling pathways were worth exploring in the mice. Scientists also state that while human testing and the use of these drugs for future astronauts would be a fantastic thing, experimentation is nowhere near ready for human trials.

               In the end, this experiment gave scientists a massive amount of hope for continuing to improve upon the safety measures and overall health of space astronauts of the present and future. We cannot wait to see the result of this groundbreaking study. If you would like the read more, click here.
