Adang has a Ph.D. in atmospheric sciences/remote sensing from the University of Arizona (thomas.c.adang@aero.org).

James G. Gee, Principal Director, Development Planning and Projects, leads support to the Air Force's Space and Missile Systems Center Developmental Planning Directorate that includes concept development, technology integration, utility and alternative analyses, and development of future systems such as 3rd Generation IR, reusable boosters, conventional strike missile, and ORS. He joined Aerospace in 1980. He provides corporate memory for Cold War-era survivability efforts and has particular expertise in weapons effects, hardening, active countermeasures, and attack reporting. Gee is the creator of the "satellite at the sensor" concept for satellite attack reporting and anomaly resolution. He has a Ph.D. in chemistry from the University of California, Santa Barbara (james.g.gee@aero.org).

Open Architectures and Standards for Agile Space

Douglas A. Harris, Senior Project Engineer, Operationally Responsive Space, supports enterprise architecture development and leads the ORS open architecture standards activities. Harris has been with Aerospace for five years supporting various Tactical Exploitation of National Capabilities (TENCAP) programs with the National Reconnaissance Office. Prior to Aerospace, he served as an Air Force Acquisition Officer for 21 years. He has an M.S. in systems management and has Project Management Professional (PMP) certification (douglas.a.harris@aero.org).

Agile Space Launch

Steven C. Weis, Project Engineer, Space Innovation Directorate, provides space vehicle to launch vehicle integration support to multiple Air Force Space and Missile Systems Center Space Development and Test Wing and Operationally Responsive Space Office missions. Prior to joining Aerospace in 1999, he served as the Air Force chief launch vehicle engineer for the Pegasus XL, Minotaur I, and Taurus small launch vehicles. Weis has an M.S. in aerospace engineering from the University of Colorado, Boulder (steven.c.weis@aero.org).

Lisa A. Berenberg, Systems Director, Satellites Acquisition and Integration, is responsible for providing technical leadership, systems engineering, and mission assurance for R&D missions within the Air Force Space and Missile Systems Center Space Development and Test Wing. She joined Aerospace in 1997 and has since supported ten space vehicle missions. She has coauthored several articles on the development and use of the EELV Secondary Payload Adapter designed for the Atlas V and Delta IV. Berenberg has a B.S. in aerospace engineering from the Georgia Institute of Technology and an M.B.A. from the University of New Mexico (lisa.a.berenberg@aero.org).

A Flexible Satellite Command and Control Framework

Thomas J. Sullivan, Senior Engineering Specialist, Ground Systems Department, joined Aerospace in 2005 after serving in the Air Force, where he managed ground systems engineering and development in the commercial sector. Sullivan currently serves as the technical director of the Aerospace Ground Systems Laboratory in Chantilly, Virginia, supporting the National Reconnaissance Office, the Air Force Space and Missile Systems Center, and the Operationally Responsive Space Office in the application of information technologies to space ground systems. He has a master's of engineering in space operations from the University of Colorado, Boulder (thomas.j.jsullivan@aero.org).

Donald G. Sather is Principal Director of the Chief Engineer's Office in the Launch and Satellite Control Division. He joined Aerospace in 1985 and has worked for numerous programs in the areas of satellite and ground system design, test, and operations. He has a B.S. in engineering from UCLA (donald.sather@aero.org).

Ronald G. Nishinaga is Principal Director of the Air Force Satellite Control Network Directorate. He joined Aerospace in 1970 and has supported numerous space and ground command, control, and communications system programs. His organization received the Aerospace Program Recognition Award in 1994 for work on the Consolidated Space Operations Center. He has a Ph.D. in space systems engineering from UCLA (ronald.g.nishinaga@aero.org).

Developing a Responsive Ground System Enterprise

Rico J. Espindola, Project Engineer, Space Innovation Directorate, serves as the mission operations representative within the ORS Office, providing satellite operations experience and technical support. He assists the ORS Office in accomplishing tasks to develop end-to-end ORS enablers required to meet the nation's strategic need for highly responsive space capabilities. Espindola has a B.S. in physics from New Mexico Tech (ricardo.j.espindola@aero.org).

Gayla F. Walden, Systems Director, Flight Operations and Ground Systems Engineering, is responsible for providing technical leadership, systems engineering and mission assurance for ground system development, and readiness and flight software analysis and monitoring within the Air Force Space and Missile Systems Center. She joined Aerospace in 1987 and has since supported a wide variety of system engineering activities including the Airborne Laser Program. Walden has a B.A. in computer science from the University of Texas, Austin, and an M.S. in electrical engineering from the University of Southern California (gayla.f.walden@aero.org).

Building Miniature Spacecraft at The Aerospace Corporation

David. A. Hinkley, Project Leader, Mechanics Research Office, joined Aerospace in 1987 and has designed several portable laboratory testbeds, including LIDAR Trailer One and the portable OPO laser system. He was the mechanical designer for the first two Aerospace Corporation picosatellite missions and systems engineer for the remaining missions. He has a B.S. in mechanical engineering from the University of California, San Diego, and an M.S. in manufacturing engineering (with an emphasis in robotics) from UCLA (david.a.hinkley@aero.org).

Siegfried W. Janson, Senior Scientist, Mechanics Research Office, is the co-editor of Small Satellites: Past, Present, and Future (The Aerospace Press/AIAA, 2009). Since joining Aerospace in 1987, he has played a key role in creating and then shaping and directing the United Kingdom Foreign Comparative Test program for the evaluation of British ion engines for eventual use on U.S. satellites. His technical expertise includes micropropulsion and microtechnologies for future space systems.
