This original NASA+ documentary follows teams of scientists and astronomers as they track and monitor near-Earth asteroids to protect the planet from severe impacts.

Could an asteroid, like the one that destroyed the dinosaurs, endanger civilization as we know it? That's the question that led NASA to establish the Planetary Defense Coordination Office.

Planetary Defenders, a documentary from NASA+, follows the scientists and astronomers tasked with keeping the Earth safe from life-threatening asteroids.

From sky surveyors to asteroid researchers, the Planetary Defense Coordination Office is made up of several NASA departments and other institutions to defend the planet against unknown objects in space.

The documentary shines a light on the heroic work of planetary defenders while spreading awareness of the impact of asteroids and the strides made to prevent global devastation.
