Embark on an extraordinary odyssey through the heart of the world's driest nonpolar desert – the Atacama. In Mars on Earth, intrepid journalist Mark Johanson navigates this otherworldly terrain, a sliver of camel-coloured hills, windswept dunes, and desolate salt flats nestled between the Pacific's tumultuous waves and the towering Andes. Unfolding against the backdrop of Chile's 2019–2020 protests, Mark's journey begins in Santiago, unravelling a rich tapestry of human resilience and passion that fuels a nation's desire for change.

As he traverses 1,200 miles of alien landscapes, Mark climbs to the Andean altiplano's dizzying heights, explores the Pacific's kelp forests, and ventures onto a lithium-rich salt flat threatened by progress. The narrative reaches new heights as Mark delves into the heart of the Atacama, meeting captivating characters – a guardian of ancient mummies, a guru in a glass box, and a copper miner who defied nature's grasp for 69 days. At its core, Mars on Earth weaves a rich tapestry of voices, highlighting the stories of Chile's marginalized communities, including the working class, Indigenous Peoples, LGBTQIA+ individuals, and immigrant communities from Venezuela and Haiti. Each narrative contributes to the social movement that could redefine the nation's future. This vibrant and adventurous work of narrative nonfiction is a captivating exploration of a land both barren and brimming with life.
