We’re close to finding alien life on Mars, but ‘we’re not ready for it’
Nasa’s chief scientist says we may not be prepared for revelations from missions to the Red Planet

Next year, two rovers from Nasa and the European Space Agency (ESA) will travel to Mars to drill into rocks, deep into the surface, in the hope of finding evidence of living organisms.
The missions are humanity’s best chance yet of answering: are we alone in the universe?..
