Human genes could be modified to allow survival in space

Humans have an easy life here on Earth, but it’s only because we’ve had hundreds of thousands of years to evolve and adapt to our planets environment. This in turn has made us perfectly suited for life here. In the microgravity of outer space or potential macrogravity of another planet, it’s a completely different story.
The longest amount of time that a human has spent in space is around fourteen months. Even this amount of time in microgravity leads to bone loss, muscle atrophy, cardiovascular problems and other adverse physiological and psychological effects. Not to mention the potential different environments of other planets we might be forced to attempt to inhabit.
Rather than attempt to combat all these environmental obstacles by engineering new technology that allows our survival in the uninhabitable environment that is outer space, why don’t we just engineer ourselves? Instead of constructing suits of armor and creating lead barriers to protect our bodies, we can simply just modify our genetic code to be resistant to these problems. And Mother Earth has already invented an incredible array of bacteria/microbes that provide us with these environmentally resistant genes.
That’s what Lisa Nip (doctoral candidate at the MIT Media Lab) is suggesting in her recent TED Talk. Through the use of synthetic biology, Lisa strongly suggests that scientists will be able to genetically modify humans, plants and bacteria.
This will in turn allow space travel and the terraforming of planets to be less reliant on our ability to create technology, such as engineering a hermetically sealed environment to allow plant growth.
Lisa suggests that extremophile bacteria hold the key, using Deinococcus Radiodurans as an example. One of the world’s toughest bacterium, it can withstand one hundred times the ionizing radiation levels lethal to a human, with no apparent adverse effects.
