The development of industrial applications involving ``low-temperature'' plasmas is in a phase of rapid expansion. Recently added to continuing development in areas where plasmas have been used for many years, such as integrated circuit fabrication, are new applications such as plasma medicine and plasma agriculture which have tremendous potential for societal benefit. The attraction of plasmas for these applications derives from the role of the free electrons present in all plasmas, regardless of application. A critical, unique quality of plasmas is the capability of non-equilibrium chemistry. What this means in practice is the plasma contains a very hot electron population while the gas and substrate remain at or near room temperature. Collisions between energetic electrons and molecules in the gas phase lead to chemical reactions that would require a high temperature reactor in the absence of the plasma.  While much has been accomplished to date, this proposal is a response to calls for tools enabling ``predictive design'' of plasma processes. In particular, we seek to develop the untapped potential of the plasma glow as a diagnostic to probe the characteristics of the plasma. MENTION community demand - plasma 2020, low temperature plasma report, etc.  Low cost, easy to implement. SHARE CODE  Low pressure plasmas generated in pure oxygen have technological significance in a number of materials processing applications. Such processes rely on the interaction of neutral radicals, O$^+$ and O$_2^+$ with substrate surfaces exposed to the plasma. In many applications, achievement of process goals is sensitive to the relative fluxes of the different gas phase species to the substrate surface. Production of ion and neutral radical species occurs primarily through gas phase reactions involving collisions with energetic electrons, so that production {\it rates} are sensitive functions of electron density and electron temperature.  Rocket club -- The Rocket Club at Madison West High School is an extracurricular activity in which West High students engage in rocket competitions, local public outreach events and fundraising to support the club's activities. The club, founded in 2003, regularly participates in national competitions, including the Team America Rocket Challenge and the NASA Student Launch program program,  and has won numerous awards. The club maintains a traveling exhibit for outreach events. Creating paper rockets and launching them with the  club's pneumatic launcher is popular among
