The Cislunar Explorers team are based at Cornell University in Ithaca, NY. Our team is primarily made up of undergraduate students, with several graduate students as technical leads and associate professor Mason Peck as the team’s advisor and principal investigator. We have also partnered with the National Space Society, a grassroots non-profit that supports space exploration and settlement.

In our lab at Cornell we have access to our own clean room, thermal vacuum chamber, air-bearing test stand, and two radio ground stations, all facilities dedicated to building and supporting our mission: to achieve lunar orbit and demonstrate our key new technologies of electrolysis propulsion and optical navigation.
