Susan K. LaVoie is the Co-Investigator and Institutional PI for the Imaging Node. LaVoie provides oversight of Imaging Node tasks carried out at JPL, sets the technical direction for the Imaging Node and provide management of those activities, assists the PI in negotiation of project requirements and funding; participates in the PDS Management Council, and works with the PI and with Imaging Node staff to define project objectives, schedules and budgets for Imaging Node activities. LaVoie has extensive management experience in the development and operations of large complex systems to support planetary mission instrument data processing and archive. LaVoie has been involved in the Imaging Node since the PDS pilot program—first as Test-Bed Manager, now as Co-I and Sub-Node Manager. In 2002, LaVoie held the role of PDS-Distribution System Development Manager. She has been the PI and Co-I on several data restoration and data access projects, served as the image processing and mission interface lead for several missions, and is currently Assistant Manager of the Instruments Software and Science Data Systems Section at JPL.

Scott Akins, software engineer, primarily works on database and web interface development. He has 16 years of experience in software development and is working on the Unified Planetary Coordinates (UPC) database, web presentation and processing cluster to generate statistics for the UPC database from EDR images.

Rafael Alanis, data engineer and geologist, is the Mission Interface lead for the PDS Imaging Node at JPL, responsible for coordination of archiving activities during all phases of the mission. Currently, he supports instrument teams on Mars Science Laboratory (MSL), Mars Reconnaissance Orbiter (MRO), Mars Exploration Rovers (MER), Lunar Reconnaissance Orbiter (LRO), and India's Chandrayaan-1, Moon Mineralogy Mapper (M3). Alanis is also actively involved in PDS data standards development, capture and safing of instrument calibration data, and data restoration.

Janet Barrett, software engineer (along with Kris Becker), shares responsibility for providing Imaging Node software. Barrett has 16 years of experience in software development and image processing, with expertise in image file-format translation and display tools, and database design and management. Barrett develops ISIS software to translate and ingest PDS data.

Kris Becker, software engineer (along with Janet Barrett), shares responsibility for providing Imaging Node software. Becker has 18 years of experience in computer programming and system design. Becker develops software for interfacing with the OODT environment and for creating an image product database for the uniform coordinate system.

Karen Boggs is the PDS Imaging Node site manager assisting with PDS Imaging Node web development at JPL and responsible for all updates. In addition, Karen is webmaster for NASA's Photojournal and is responsible for the population of high resolution images from all JPL missions to both the Photojournal and JPL's Space Images iPhone app, working closely with JPL Media Relations for timely press releases to the public.



Dr. Philip Christensen is a Regents Professor in the Department of Geological Sciences at Arizona State University (ASU). In addition to his active research program on surface processes on Mars, Phil is Principal Investigator for the Mars Global Surveyor Thermal Emission Spectrometer (TES) and Mars Surveyor 2001 Orbiter Thermal Emission Imaging System (THEMIS) instruments, and Co-Investigator on the Mars Exploration Rovers (Athena), providing the Mini-TES instrument. Christensen is an expert in the analysis, acquisition, and processing of planetary image data for the Earth and other terrestrial planets.

Ernest Bowman-Cisneros is a systems and software engineer at the School of Earth and Space Exploration at Arizona State University (ASU). Ernest is the Manager of the Lunar Reconnaissance Orbiter Cameras (LROC) Science Operations Center at ASU, and he also is the Node Lead for the LROC PDS Sub-Node.



John Diehl is a member of the Instrument Operations System Engineering group at JPL. His work with the Imaging Node primarily involves the acceptance of archive volumes from the Cassini ISS and VIMS instruments for the PDS Atlas.




Patricia Garcia, computer scientist and senior data engineer, has provided Mission Interface and Data Standards Development support for the USGS Sub-Node since 1995. Patty has led or participated in national workgroups on PDS standards. Garcia's primary duties for the PDS focus on coordinating data archive activities with mission instrument teams for MRO HiRISE, Odyssey THEMIS, LCROSS Cameras and Messenger MDIS. Patty has primary responsibility for compiling the Imaging Node monthly and quarterly reports. She is also currently working on Apollo Metric and Apollo Rock Sample restoration archives.

Dr. Paul Geissler, planetary scientist, is the science advisor to the Imaging Node. Geissler has been active in mission planning and data analysis for the Galileo and Cassini missions and has experience in multi-spectral, multi-temporal and multi-phase angle imaging of outer Solar System satellites. Geissler provides input to the Imaging Node regarding the specific science requirements for research on icy satellite surfaces and atmospheres, and supports the Imaging Node interface to the Rings Node on data for the Outer Planet Satellites.

Rod Heyd is a systems and database specialist at the HiRISE Operations Center, Lunar and Planetary Laboratory (LPL) of the University of Arizona in Tucson. Rod is the primary interface of the HiRISE Data Node with the Imaging Node.

Chris Isbell, cartographer, is the Technical Manager of the USGS Sub-Node facility. Isbell is Assistant Team Chief Scientist (Acting) for Technical Operations in Astrogeology, and he has provided the Imaging Node with software and catalog development, data processing, and data archive design since 1994. Isbell is supervisor and manager for the Astrogeology Data Dissemination and Publications Group. He has substantial expertise in data restoration and data publishing and provides support for cartographic and research projects. He led the design and production of the Galileo/NIMS EDR data products and the archive processing and production of the Clementine UVVIS Digital Image Model products. In addition, Isbell installed initial versions of the International Astronomical Union's gazetteer of planetary nomenclature on the Node's search and retrieval catalog.

Dr. Alfred McEwen is a Professor in the Department of Planetary Sciences at the University of Arizona in Tucson, where he leads a group of about 30 students, researchers, computer scientists, and staff members working on several planetary spacecraft experiments and research projects. His research interests are geologic processes on planets and satellites, including pyroclastic and flood volcanism on Earth and Mars; active volcanism and other processes on Io; impact cratering on the Moon, Mars, and outer planet satellites; and fluvial and other processes on Mars and Titan. Alfred's participation in spacecraft exploration includes imaging experiments on Voyager, Galileo, Clementine, Mars Global Surveyor, Mars Odyssey, Mars Reconnaissance Orbiter (MRO), Cassini, and Lunar Reconnaissance Orbiter. On MRO he is the Principal Investigator of the High Resolution Imaging Science Experiment (HiRISE), the most powerful telescope to ever visit another planet. HiRISE has been returning a flood of new Mars images since November 2006.
