An ongoing challenge in the long-term campaign to explore Mars is the mass and complexity involved in transporting consumables from Earth to the Martian surface. CEO Jeff Greenblatt was invited to participate in a workshop sponsored by Caltech's Keck Institute for Space Studies to explore ways to produce oxygen and fuel from in situ resources on Mars, e.g., water, carbon dioxide and sunlight. Two workshops were held in June and September 2016 in Pasadena, CA.
