Makel Engineering, Inc. (MEI) proposes to continue to development of a highly compact Multi-Parameter Astronaut Life Support Sensor (M-PALSS) for use in the portable life support system (PLSS) for the new Exploration Extravehicular Mobility Unit (xEMU).nbsp; M-PALSS will consist of an array of low power chemical microsensors for oxygen, carbon dioxide, water vapor, and pressure to monitor the major constituents in the gas stream circulated by the PLSS and/or exhaled from the astronaut in the rebreather loop. In Phase I, highly miniaturized chemical microsensors were packaged with electronics in a compact physical envelope and low power consumption.nbsp; Phase II will develop and test prototypes ready for PLSS integration and will coordinate designnbsp; and requirements with NASA, Collins Aerospace, and Axiom Space. Additional sensing capability for ammonia, carbon monoxide, and other chemical sensing gaps will be evaluated for integration.nbsp; In Phase II, two generation of prototypes will be developed and tested to mature the technology to TRL 6 by the end of the program.
