Oxygen and Fuels from In-Situ Resources on Mars

ISRU system concept for autonomous robotic excavation and processing of Mars soil to extract water for use in exploration missions.

Customer: NASA, NextSTEP-2 ISRU
Technology: Solid Oxide Electrolysis Cells (SOEC), and Methane Synthesis Reactor

NASA Next Step



The NASA NextSTEP program is a continuation and expansion of the work OxEon has completed in association with JPL and MIT for the Mars 2020 mission, Project MOXIE (Mars OXygen In-situ resource utilization Experiment). Recognizing the need for a larger scale version of the solid oxide (SOXE) stack to meet ultimate NASA objectives, OxEon is developing a Mars manned-mission scale stack.
OxEon will demonstrate operation of the Mars manned-mission scale SOXE stack for co-electrolysis of CO2 and water vapor, and the technology to produce methane fuel from the SOXE produced synthesis gas (mixture of CO and H2). The scale of the stacks is such that four SOXE stack units will exceed the 2.3 kg/hr oxygen production rate requirement to produce 30 tons of propellant in the 435 day Mars landing to Earth launch, Mars Ascent Vehicle (MAV) propellant production window.
