In 2013, CSPP initiated a diverse research effort involving theory, spaceflight-data analysis, and ground-based experiments aimed at increasing our understanding of the plasma physics of the solar wind and Earth's magnetosphere and ionosphere. Research highlights include the development of novel spacecraft-data analysis techniques that examine the nature and characteristics of plasma waves and fluctuations at very small scale sizes, the development and analysis of computer simulations of these types of waves in the solar-wind plasma, advancing the theoretical understanding of magnetic-field-line reconnection in plasmas, and the application of reconnection theories to the interaction of the solar wind with Earth's magnetosphere. Related research highlights for the ionosphere were the development of techniques to exploit ionospheric radar, optical, and magnetic-field measurements to remotely monitor the rate of magnetic-field-line reconnection between
the solar wind and Earth's magnetosphere and the optical observation of the airglow from energetic electrons precipitating from the magnetosphere into the upper atmosphere triggered by the turn-on of a powerful military ground-based VLF transmitter. In 2013, the 7 members of CSPP published 28 papers in refereed journals: 13 papers as primary authors and 15 papers as contributing authors
In September 2013, CSPP hosted a week-long, SSI-sponsored, international workshop entitled "10th Cambridge Workshop on Magnetic Reconnection" (http://www.spacescience.org/icwm/). The workshop, organized by Dr. Joachim Birn, was held at the historic Hotel La Fonda in Santa Fe, NM. The Cambridge Workshop series originated in 2004 as a month-long workshop in Cambridge, England. Because of the success of this event, participants decided to continue collaboration through annual weeklong workshops, alternating between Europe and the United States. The focus of the Santa Fe workshop was three-fold: recent progress in reconnection physics, outstanding questions, and future research.

The study of extrasolar planets and planetary systems is one of the fastest growing and most exciting fields within astronomy and astrophysics. Recognizing the importance and timelines of the field, SSI inaugurated the Center for Extrasolar Planetary Systems (CEPS) in 2012 as part of the Institute's long-term strategic plan. The mission of this center is to carry out scientific research that will increase our understanding of the characteristics of extrasolar planets and the diverse systems in which they are found
Because the field is by nature multidisciplinary, CEPS brings together astronomers, physicists, atmospheric scientists, and planetary scientists to provide a forum for the exchange of ideas and expertise. Current research focus areas for CEPS include studies of the physical properties of planet-hosting stars, the chemistry and physics of exoplanet atmospheres, the influence of the host star on the planet and/or system characteristics, the formation and evolution of planetary systems, and the signatures of planetary formation as reflected in debris disks.
In 2014, the twelve CEPS members published more than 70 refereed scientific articles, including papers on asteroseismology and related analyses of the physical properties of Kepler stars, observational and theoretical characterization of protoplanetary disks, theoretical investigations of chemical processes affecting exoplanet atmospheric composition, and strategic planning for extrasolar planetary system observations with future missions such as the James Webb Telescope and PLATO 2.0. In 2014, CEPS also created a web site (http://ceps.spacescience.org/home-page.html), accessible through SSI's main page, to highlight research being done by center members and to provide an interface with the public and other researchers in the exoplanet field. Throughout 2014, individual CEPS members have interpreted data from space-based and ground-based telescopes, performed theoretical modeling calculations, written journal articles, presented conference talks, and submitted proposals to NASA, NSF, and various other funding agencies, including observatories. Such activities will continue in the coming years as CEPS members seek to further our understanding of the amazing diversity of planetary systems beyond our solar neighborhood.

The SSI Center for Mars Science continues to serve as a focal point for SSI researchers involved in Mars studies. The center has periodic "Journal Club" telecons where center researchers share aspects of their work. The center is also involved in outreach activities. Center director Dr. Bill Farrand and fellow SSI researcher Dr. Mike Wolff will be participating in the Denver Museum of Nature and Science "Space Day" celebration on May 31 in 2015. Dr. Farrand will also be presenting Mars science research results to the general public by being a member of a space science panel at the Denver Comic Con in late May 2015.
Center for Polarimetric Remote Sensing
CPRS Chair, Dr. Gorden Videen, Silver Spring, MD Office

Intensity and linear-polarization response from power-law size distributions of
agglomerated debris particles having different refractive indices.
The study of the polarized nature of light provides critical insights into numerous physical phenomena, including: planetary surfaces, cosmic dust, interstellar magnetic fields, planetary atmospheres, star and planet formation, and active galactic nuclei, to name just a few. The detection and measurement of polarized light are highly specialized areas of astronomical observations and instrumentation development. SSI’s Center for Polarimetric Remote Sensing (CPRS) will bring together scientists who are interested in using polarization as a remote-sensing tool in understanding their individual research areas, capitalizing on a number of senior researchers at SSI with extensive experience in the field. The CPRS will also focus on education and public engagement activities that expose students and the general public to the nature of polarized light, and its utility in science and technology.
Center for Data Science

The Center for Data Science (CDS) is an initiative to bring together domain experts in space sciences and highly skilled corporate talents sharing a common interest in Data Science and Machine Learning. Data Science and Machine Learning have profound impacts on the way scientific problems are conceived, conceptualized, and addressed today. Currently, they exist as possibilities that are gradually being inducted into the Space Sciences to augment their analytical and predictive performances. As an organization of scientists, CDS envisions to inspire the scientific community to utilize key insights on emerging technologies, transforming this possibility into reality. The societal impact of Data Science has grown considerably due to recent advances in the field, further enhanced by GPUs, big data tools and cloud computing. The Center will seek innovative collaborations with the private sector in the field, facilitating sophisticated algorithms and computational platforms. CDS will focus on arranging workshops and webinars on statistical tools, algorithms and libraries to benchmark them for their applications in the space sciences. Since "crunching big data" calls for advanced computing facilities, making GPUs and Cloud computing more accessible and affordable are among our priorities. Further, the Center will work towards broadening the range of available funding sources for space science research and advocating the inclusion of data science in academic curricula.
