Makel Engineering and the Ohio State University propose to develop a harsh environment tolerant gas sensor array for atmospheric analysis in future Venus missions. The proposed instrument will be very compact, require low power, and ruggedly packaged to be compatible with balloon a payload for atmospheric composition analysis. The goal is to provide information on local SOx (or total sulfur compounds if a reactive filter is used), CO, O2, NOx, H2 and/or water vapor concentrations in order to complement other measurement systems that were targeted in the 2009 Venus Flagship Mission Study such as a GC-MS, nephelometer, or camera/optical detector
