If early colonies are restocked with new recruits from Earth, physiological changes will be modest. But subsequent colonists may sever the umbilical.
A future manned mission to Mars might require mankind not just to improve its technological capabilities but also to tweak human DNA.
In the case of Mars, a major resource that can be processed by synthetic biology is the atmosphere.
Living anywhere in our Solar System beyond Earth will require the same level of protection that an astronaut needs while walking in space.
What will humans look like in the distant future? Space travel may may affect both biological and technological changes in our species.
NASA has turned to the fast-moving world of gene therapy to solve several potential medical issues facing astronauts on lengthy space missions.
The same synthetic biology technologies that will help sustain us on Earth will also support our journey to inhabit the stars.
Synthetic biology will become indispensable to establish a long-term human presence off-Earth, namely colonization.
Is natural selection still a major force in human evolution? We’ve been taught to think the answer must be yes. But is it really true?
As humanity looks outward, we ponder what kind of life we ought to take with us to support outposts and eventually colonies off the Earth.
