Right now, spacecraft are circling Mars, sweeping over the dunes of Elysium, Terra Sabaea and Mare Sirenum – on the brink, perhaps, of a huge discovery. Astrobiologist Sarah Stewart Johnson has developed life detection techniques on some of Earth’s most hostile environments, as well as on three NASA rovers. She believes the story of Mars is a story about Earth: a tell-tale reflection of our own anxieties and desire to find – if we’re lucky – that we’re not alone.
