Gas Inlet Sensor for Measuring Dust Particle Size Distribution and Concentration, Phase I

Metadata Updated: November 12, 2020

In-Situ Resource Utilization (ISRU) involves collecting and converting local resources into products that can be used to reduce mission mass, cost, and/or risk of human exploration. ISRU products that provide significant mission benefits with minimal infrastructure required are propellants, fuel cell reactants, and life support consumables. Production of mission consumables from in-situ Mars resources is enabling and critical for human exploration of the Mars surface and for minimizing the number and size of landers and the crew ascent vehicle.To understand both the dust concentration before filtration as well as the effectiveness of dust filtration techniques used in ISRU operations, NASA is interested in a dust sensor to measure 0.1 to 5 micron sized dust particles in the Mars atmosphere acquired for processing. 

Southwest Sciences proposes to design, build, and demonstrate a novel non-intrusive optical particle measurement technology for measuring these particles under the NASA defined operating conditions. This in-line particle concentration/size monitor is based on a variant of laser intensity attenuation.  The method is compact, low power, can be multiplexed to increase throughput and/or dynamic range, uses no consumable, and is independent of carrier gas, gas temperature and gas pressure.
