Sex in Space: The Final Frontier

Any long-distance interstellar travel will span generations which means humans must find ways to procreate in space. Gravity is essential to the healthy development of our bodies. 

What's the Latest Development?


A forward-thinking department in the Pentagon held a symposium last week to discuss problems posed by interstellar space travel. Among the topics discussed by the Defense Advanced Research Projects Agency was the problem of procreatin in space. "A trip to even one of the closest stars would take decades and possibly hundreds of years, likely spanning multiple generations. But scientists aren't even sure humans can procreate safely in the microgravity of space." Earth's gravity is necessary for healthy muscles, strong bones and good vision. 

What's the Big Idea?

The star nearest our Sun, Alpha Centauri, is four light-years away, which means it would likely take a space ship a few decades to arrive. But the necessity of procreation in space remains an obstacle which we do not have the technology to overcome. Let alone what to do when humans arrive to a foreign solar system. Assuming there is a rocky planet we could land on, how would we survive the new world? Terraforming an atmosphere is one option. Another is engineering our biology to suit a new environment. That might create two distinct human species, incapable of breeding with each other.

Surprising Science
  • According to some relatively new research, many of our early human cousins preceded Homo sapien migrations north by hundreds of thousands or even millions of years.
  • Cross-breeding with other ancient hominids gave some subsets of human population the genes to contend and thrive in colder and harsher climates.
  • Behavioral and dietary changes also helped humans adapt to cold climates.

  • Lee died shortly after being rushed to an L.A. hospital. He had been struggling with multiple illnesses over the past year, reports indicate.
  • Since the 1950s, Lee has been one of the most influential figures in comics, helping to popularize heroes that expressed a level of nuance and self-doubt previously unseen in the industry.
  • Lee, who's later years were marked by some financial and legal tumult, is survived by his daughter, Joan Celia "J.C." Lee.
