One large (9ft long by 5ft diameter) and one small (2 ft long by 1 ft diameter) plasma chambers are used to study advanced plasma systems that would facilitate low cost in-space propulsion to further space exploration. Concepts presently being investigated include small scale micro-thrusters for small multi-spacecraft missions to very large high power systems for potential large spacecraft. Students participate in the development and optimization of prototypes using an array of plasma diagnostics and a fast data acquisition systems. For more information, contact Robert Winglee.
The Aeronomy and Optics Lab serves as an educational, training, research and development facility, as well as being the staging area for our field site experiments in Antarctica and New Zealand, where Global Climate Change studies in the Southern Hemisphere are in progress. The laboratory serves as the support arm for these far away experiments, as well as to provide new and improved optical instrumentation which will perform measurements with higher precision than previously attained, rugged instrumentation for unmanned sites, or to study atmospheric species which have not been used previously as tracers in our remote-sensing studies. In addition, design and fabrication of instrumentation which supports the main optical studies, such as an unmanned sunlight-insensitive cloud detector, have been carried out in the Aeronomy and Optics laboratory. As part of the support, the laboratory is where the Antarctic Research Associates receive their yearly training. The laboratory investigations provide a wide range of research possibilities for students. For more information, contact Gonzalo Hernandez or Michael McCarthy.
The Atmospheric Electrodynamics Lab in the Space Sciences Group is a space for electronics development and deployment, as well as for payload fabrication for suborbital flights. We have both fabrication benches, as well as operational network computers for the WWLLN lightning network in the Atmospheric Electrodynamics Lab. Additionally, we share a large Assembly Room with the other Space Science Labs for balloon and rocket payload buildup. Our lab has a conduit to the roof for VLF and GPS antenna deployment. We share a clean room for dust free flight instrument development. The Atmospheric Electrodynamics Lab is the home of the WWLLN: World Wide Lightning Location Network. We build the hardware, and process the incoming global data in this lab. Additionally, we have built electric field and optical transient detectors for dozens of stratopheric balloon and for several upper atmospheric rocket flights. These flight instruments led to the optical lightning detector now flying on the C/NOFS satellite. For more information, contact Robert Holzworth.

The room houses a complete library of the journals Tectonics and Journal of Structural Geology, theses and dissertations supervised or co-supervised by Prof. Darrel Cowan, and relevant texts and publications. Typically one or two graduate students use the workroom as an office, and the room also serves as a space for seminars and meetings of our reading group. For more information, contact Darrel Cowan.
