What will humans look like in the distant future? Space travel may affect both biological and technological changes in our species.
One of the biggest concerns that space agencies like NASA and SpaceX have when it comes to bringing humans to Planet Mars is survival.
A future manned mission to Mars might require mankind not just to improve its technological capabilities but also to tweak human DNA.
The same synthetic biology technologies that will help sustain us on Earth will also support our journey to inhabit the stars.
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?
NASA has turned to the fast-moving world of gene therapy to solve several potential medical issues facing astronauts on lengthy space missions.
Synthetic biology will become indispensable to establish a long-term human presence off-Earth, namely colonization.
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.
If early colonies are restocked with new recruits from Earth, physiological changes will be modest. But subsequent colonists may sever the umbilical.
Living anywhere in our Solar System beyond Earth will require the same level of protection that an astronaut needs while walking in space.
