Biologists try to engineer life that can survive on Mars and aid colonisation

With Nasa’s Curiosity Rover safely on Mars and ready to search for signs of life, back on Earth attempts are underway to engineer bacteria that could thrive on the Red Planet.

A team of undergraduates from Stanford and Brown Universities are busy applying synthetic biology to space exploration, outfitting microbes to survive extreme Martian conditions and produce resources needed to sustain a human colony.

Though Mars is potentially a place where life may have survived at some point, it is not an especially friendly environment, and thriving there will not be easy — for humans or microbes. The average surface temperature of Mars is minus 80 degrees Fahrenheit, and the almost-nonexistent atmosphere is 95 percent carbon dioxide. Although water exists in Mars’ ice caps and there’s some evidence that giant oceans once covered the planet, today it’s essentially a deep-frozen desert. Colonising Mars would be challenging and pricey.
