Our DNA would have to be tailored specifically to enable a long, healthy life on Mars, including genetic tweaks for good muscle, bone, and brain health. These traits could be made heritable, such that Martian colonists could pass down the characteristics to their offspring. In cases where biology is not up for the task, scientists could use cybernetic enhancements, including artificial neurons or synthetic skin capable of fending off dangerous UV rays. Nanotechnology in the form of molecular machines could deliver medicines, perform repair work, and eliminate the need for breathing and eating. Collectively, these changes would result in an entirely new species of human—one built specifically for Mars.

I enjoyed this article, but I thought it was silly to have a section about genetic and cybernetic modifications when it opened by complaining about NASA/Elon being too sci-fi for their own good.
