MOXIE (Mars OXygen In situ resource utilization Experiment) is an exploration technology experiment that will produce oxygen from Martian atmospheric carbon dioxide (CO2) in a process called solid oxide electrolysis. MOXIE is a 1% scale model aboard the planned Mars 2020 rover.〔(The Mars Oxygen ISRU Experiment (MOXIE) ) PDF. Presentation: MARS 2020 Mission and Instruments". November 6, 2014.〕 The Principal Investigator of the MOXIE instrument is Michael Hecht from the Massachusetts Institute of Technology (MIT).〔 The Niels Bohr Institute at the University of Copenhagen is collaborating with MIT to develop this prototype.〔 ==Objective== The main objective of this experiment is to produce oxygen on Mars, where the atmosphere is 96% carbon dioxide.〔〔(Going to the Red Planet )〕 Scientists will record the efficiency of the O2 production rate, and the resulting oxygen and carbon monoxide will be vented out after measurements are done. To achieve this objective, the MOXIE instrument has a goal of producing 22 g of oxygen (O2) per hour with >99.6% purity during 50 sols (Martian days).〔〔 High purity is crucial as future astronauts will breathe it. NASA officials stated that if MOXIE worked efficiently, they would land a 100 times larger MOXIE-based instrument on Mars, along with a radioisotope thermoelectric generator. Over the course of some years the generator would power the system, which would produce up to two kilograms of oxygen per hour, and fill an oxygen reservoir that could be used when astronauts arrive sometime in the 2030s.〔 The stored oxygen could be used for life support, and can also be used as rocket propellant oxidizer to power their return trip to Earth.〔(Living off the Land in the Final Frontier ). NASA, October 31, 2014.〕 The carbon monoxide (CO), a byproduct of the reaction, may also be collected and used directly as propellant〔G. Landis and D. Linne, "A Mars Rocket Vehicle With In-situ Propellant Production", ''AIAA Journal of Spacecraft and Rockets, Vol. 38,'' No. 5, Sept.-Oct. 2001, pp. 730-735〕 or converted to methane (CH4) for use as propellant.〔〔(Ceramic Oxygen Generator for Carbon Dioxide Electrolysis Systems )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Mars Oxygen ISRU Experiment」の詳細全文を読む スポンサード リンク
