Atmosphæra Incognita is a beautifully detailed, high-tech rendering of a tale as old as the Biblical Tower of Babel. It is an account, scrupulously imagined, of the years-long construction of a twenty-kilometer-high tower that will bring the human enterprise, in all its complexity, to the threshold of outer space. It is a story of persistence, of visionary imaginings, of the ceaseless technological innovation needed to bring these imaginings to life.

At the same time, it shows us our familiar planet from an entirely new perspective, and offers vivid snapshots of the unique beauties and unexpected hazards of the “atmosphæra incognita” that lies between this world and “the deep ocean of the cosmos.”
