50 years ago, on Christmas Eve, human beings orbited the moon for the first time. The New York Times published a frontpage essay by the poet Archibald MacLeish the following day, a reflection inspired by the remarkable images from Apollo 8. Chief among them was the now iconic "Earthrise," the first photograph of Earth from space to capture the world's imagination. In this short film, SALT brings MacLeish's words to life, along with voices from Apollo 8, inviting us again to see our home planet as a wondrous, precious treasure, and to see ourselves as life's guardians.
