MICHAEL J. BLOOMFIELD is vice president and general manager of Oceaneering Space Systems at Oceaneering International, Inc. Prior to joining Oceaneering, he was vice president for Houston operations at Alliant Techsystems, Inc. (ATK). Mr. Bloomfield is a veteran astronaut of three space shuttle flights. Selected as a NASA astronaut in 1994, he served as pilot on STS-86 and STS-97 and as commander of STS-110. While at NASA he also held important management positions with the astronaut office, including chief instructor astronaut, chief of astronaut safety, and deputy director of flight crew operations. Additionally, Mr. Bloomfield was director of shuttle operations and chief of the shuttle branch. He also served as deputy director of the Flight Crew Operations Directorate before leaving NASA in 2007 to join ATK. Mr. Bloomfield received his B.S. in mechanical engineering from the U.S. Air Force Academy and his M.S. in engineering management from Old Dominion University. He served on the Committee on the Assessment of NASA’s Orbital Debris Programs.
JOHN T. EMMERT is a research physicist in the Geospace Science and Technology Branch within the Space Science Division at the Naval Research Laboratory. Dr. Emmert’s research focuses on the climate and dynamics of the thermosphere, using a variety of extensive geophysical databases and models. He recently developed a 40-year database of thermospheric densities derived from orbital tracking of 5,000 near-Earth space objects. He has employed this data set for continuing studies of long-term upper atmospheric climate change, for analysis of the thermospheric response to solar activity variations, and for validation of thermospheric densities inferred from far-ultraviolet remote sensing. He has also studied extensively the effect of geospace storms on global thermospheric dynamics and has developed a global empirical model of geomagnetic storm effects on thermospheric winds. Dr. Emmert received a B.S. in astronomy from the University of Arizona and a Ph.D. in physics from Utah State University.
YANPING GUO is a supervisor of the Mission Design Section in the Space Department of the Johns Hopkins University Applied Physics Laboratory, where she is also a member of the principal professional staff and started her career as a postdoctoral fellow. Dr. Guo has developed mission designs for several interplanetary missions and is the mission design lead of NASA’s New Horizons mission to Pluto and the Kuiper belt and is the mission design and navigation manager of NASA’s Solar Probe Plus mission. Dr. Guo was the mission design lead for several missions, including NASA’s decadal study of Uranus Orbiter/Probe mission, the Mercury Lander mission, the MERLIN Discovery mission proposal, the Mars Scout mission proposal “The Great Escape,” NASA’s Solar Sentinels mission study, and a proposed Aladdin mission to return samples from Mars’ moons Phobos and Deimos. Dr. Guo served on review panels for NASA’s MESSENGER and MAVEN missions. She was the lead for science planning and operation of NASA’s NEAR mission and the principal investigator of the Interplanetary Autonomous Navigation project. Asteroid 28513 was named “Guo” by the International Astronomical Union in 2004 in honor of her contribution to the exploration of the solar system. Dr. Guo is currently the chair of the AIAA Astrodynamics Technical Committee. Dr. Guo earned a Ph.D. in physics from the Catholic University of America.
TIMOTHY D. MACLAY is the founder and CEO of the consulting firm Celestial Insight, Inc., which offers services in the areas of flight dynamics, satellite operations, and space technology development. Dr. Maclay’s principal contract is for ongoing support to the low-Earth-orbit constellation owner/operator, Orbcomm, Inc. Previously, he led the systems engineering, flight dynamics, and network service assurance groups at Orbcomm, supporting the successful deployment of 41 satellites via six launch campaigns. His research interests include orbital debris modeling and space situational awareness and the development of nontraditional means of lowering the cost of access to space through the use of hosted payloads and commercially provided space data services. Dr. Maclay earned his Ph.D. in aerospace engineering sciences from the University of Colorado, Boulder. He served as the Orbital Debris Modeling Subcommittee chair on the NASA Engineering and Safety Center’s Micrometeoroid and Orbital Debris Risk Analysis for NASA’s Orion Program.
JAMES G. MILLER joined Omitron, Inc., as a senior aerospace engineer in February 2012. During the previous 25 years he was a principal engineer at the MITRE Corporation, working on missile defense and space surveillance,
