Terra-Forming: Should We Remake Mars in Earth’s Image?
by Ray Villard
We will eventually have the technology to make Mars a more habitable planet — but for whom? Earthlings, or Martians?
By definition, Mars terraforming would make it more Earth-like. Alternatively, Mars renovation would seek to resuscitate any native life that might have survived in environmental niches for billions of years. Astrobiologist Chris McKay, of NASA’s Ames Research Center, favors a non-geocentric term: planetary ecosynthesis, for establishing a robust biosphere on a planet’s surface.
Mars is certainly a prize for colonization. The Red Planet has as much surface area as all of Earth’s continents combined, making it the focus of several grassroots space pioneering groups.
But this presents a conundrum. McKay asks if a biologically rich and diverse Mars is more valuable than largely preserving the beautiful, but seemingly dead, world we are exploring today…
