From Aztec sun stones to satellite launches, from muralist visions to dark sky parks, Mexico's engagement with outer space is fundamental to its identity. Mexico in Space offers a groundbreaking look at how the country has navigated the tensions between technological dependence and sovereign dreams. Anthropologist Anne W. Johnson reveals Mexico's unique relationship with outer space, describing Indigenous knowledge, nationalist projects, artistic visions, and community practices. Through rich ethnographic detail and historical insight, Johnson challenges the notion that space is for everyone and shows whose voices truly shape the world's cosmic futures. Johnson introduces us to satellite engineers, community astronomers, space generation youth, and artists imagining Mars, each crafting alternative cosmic futures. As space exploration increasingly becomes the domain of billionaires and superpowers, this book offers a compelling counternarrative, demonstrating how Mexican cosmic engagements suggest more just, inclusive ways of inhabiting Earth and beyond and providing vital lessons for reimagining humanity's place in the cosmos.
