Colonizing Space To Result In Genetic Changes, Stark Differences To Earth-Bound Humans

Right now, there are several initiatives both public and private that have to do with going to space or colonizing another planet. Regardless of the reasons for doing so, one of the biggest obstacles to actually developing methods of long-term habitation outside of earth is the matter of unknown changes to the body. A good example is how it has been proven that even a few months of living in space is enough to change humans at the genetic level.

There are have been numerous studies related to the changes that astronauts experience during extended missions in space. One of these studies involved twin subjects Mark and Scott Kelley who participated in a research where one spent months in space while the other stayed on earth, Futurism reports. After the period was up, scientists then compared their bodies to see what changed.

Since the twins shared genetic similarities that were the closest humans could possibly get, they were the perfect subjects to test for genetic variance and the effects of spending too much time in space. The scientists noticed several key differences between the twins’ chromosomes, bacterial presence, and even their DNA.

This is just the beginning, however, as the case of the twins is too small a sample to make any kind of solid conclusion. However, it does provide a good base for future research involving other astronauts.

As NASA also points out, there will be several stark changes in the body of humans if they stay too long in space. Among these changes is the loss of bone density thanks to the lower gravity and the reduced muscle strength.

All of these factors are going to come into play, especially for those going on the planned one-way trip to Mars in order to colonize it. Based on the evidence so far, it’s a fair bet that the volunteers will no longer be the same by the time they have achieved their goals.
