As far as locations for Mars dress rehearsals go, you could do worse than Chile's Atacama Desert. Regarded as the driest place on the planet, parts of this parched desert landscape have never seen a single drop of rain, making them largely hostile to life on Earth. Sounds a bit like Mars right? Over the month of February, NASA researchers have been using the site to test a rover equipped with scientific instruments needed to comb the Red Planet for signs of life, with a view to fine-tuning the tech ahead of future Mars missions.
