The popular imagination has seen a resurgence of interest in space research. It is fueled by the discovery of over 1,000 exoplanets, promising discoveries on Mars, and recent successes in commercial space exploration.

The New York Times articles collected in this volume will reveal how concerns about planet Earth and space research development contribute to the quest for space colonization.
