Could we live on Mars? Would we want to? Ian Cheney (The City Dark) examines our fraught relationship with our homeworld by delving into the sci-fi speculation of “terraforming,” or making another planet Earth-like, by altering its atmosphere. He calls on a fanciful brain trust to process this big idea: a desert camp of Mars hopefuls; a bevy of novelists; Hurricane Sandy survivors; a Brooklyn canoe club. Bluespace makes a strong case for taking better care of our water-rich planet so that future generations won’t have to resort to interplanetary colonization.

Directed and produced by Ian Cheney.
