Civilian Uses of Surveillance Satellites

Dee W. Pack, Remote Sensing Department, leads research on the civil and scientific applications of DSP satellites. Pack joined Aerospace in 1989 and has since worked in several different fields of applied and basic remote sensing research, including recent work in support of the USGS and NRO Hazard Support System. His academic degrees are in physical chemistry. He received a B.S. from the University of Virginia, a Ph.D. from Princeton University, and worked as a postdoctoral researcher at Stanford University prior to joining Aerospace. Dee.W.Pack@aero.org. Carl J. Rice directs the Remote Sensing Department, which supports a number of DOD and NASA programs. Rice joined Aerospace in 1969. His fields of specialization include remote sensing of infrared emissions from the Earth, the atmosphere, and various other phenomena, and in situ measurements of the upper atmosphere and ionosphere and precipitating energetic particles. He received an A.B. in physics from the University of Utah and a Ph.D. in physics from the California Institute of Technology. Carl.J.Rice@aero.org. Barbara J. Tressel, Space Systems Evaluation Department, is responsible for the development and operations of ARC, one of the corporation's research centers. Tressel holds a B.S. in electrical and computer engineering from the University of California, Santa Barbara, and an M.S. in electrical engineering from the University of Southern California. Barbara.J.Tressel@aero.org. Carolyn Lee-Wagner, Space Systems Evaluation Department, is currently responsible for software design and development for several space system architecture planning tools, as well as for ARC. Lee-Wagner joined the corporation in 1983. She holds a B.S. in mathematics from the University of Toledo. Carolyn.J.Lee-Wagner@aero.org. Edgar M. Oshika is a senior engineer in the Space Based Surveillance Division and has been at Aerospace since 1980. He previously directed the integration of space and ground communications for SBIRS and DSP. While at the Charles Stark Draper Laboratory, Oshika wrote the Lunar Module Backup autopilot software used in the Apollo 13 mission. He received a B.S. in mechanical engineering from Wayne State University and an M.S. in information and control engineering from the University of Michigan. Edgar.M.Oshika@aero.org.

Atomic Clocks Meet Laser Cooling

Walter F. Buell is a member of the technical staff in the Photonics Technology Department, where his research activities include laser-pumped and laser-cooled atomic clocks and optical signal processing. Before joining Aerospace in 1997, Buell spent a year as visiting scientist at the Max Planck Institute for Quantum Optics in Munich and performed post-doctoral research in laser cooling of atoms at the State University of New York at Stony Brook. He has written more than 20 papers in atomic, molecular, and optical physics. He received a B.S. in physics from the University of Rochester, and M.A. and Ph.D. degrees in physics from the University of Texas at Austin. Walter.F.Buell@aero.org. Bernardo Jaduszliwer is principal director of the Electronics Technology Center. He has been involved in atomic clocks and their applications in space systems such as GPS and Milstar since joining Aerospace in 1985. He also lectures in physics at the University of Southern California. He came to Aerospace from New York University, where he was a faculty member of the physics department. Jaduszliwer graduated from the University of Buenos Aires as a Licenciado en Ciencias Fisicas. He received M.Sc. and Ph.D. degrees in physics from the University of Toronto.

Lasers Simulate Space Radiation Effects

Steven C. Moss manages the Lidar, Optical Propagation, and Spectroscopy Section of the Photonics Technology Department. He also studies radiation effects on microelectronic devices, microelectronic materials, and ultrafast phenomena, and develops lasers and optical systems. Moss received a B.S. in physics and mathematics from Arkansas A&M College in 1970, an M.S. in physics from Purdue University in 1972, and a Ph.D. in physics from North Texas State University in 1981. Moss was a National Research Council postdoctoral research associate at the Naval Research Laboratory prior to joining Aerospace in 1984. Steven.C.Moss@aero.org. Susan J. Humphrey is working on the development of a facility for testing the susceptibility of microelectronic devices to radiation effects using short pulsed X-rays. She has extensive experience with lasers and optical spectroscopy. Humphrey received a B.S. in chemistry from Juniata College in 1991, a Ph.D. in physical chemistry from the University of Pittsburgh in 1996, and did post-doctorate work at the University of California, Santa Barbara, before joining Aerospace in 1997. Susan.J.Humphrey@aero.org. Stephen D. LaLumondiere has extensive experience with lasers, optics, and electro-optics, as well as digital and analog microelectronics. His current work includes pulsed laser testing of microelectronics for single event effects, testing of radiation-tolerant CCDs, and detection of chemical and biological materials. LaLumondiere received an A.S. in laser and electro-optics technology from Vincennes University in 1987, when he joined Aerospace. Stephen.LaLumondiere@aero.org.

New Hazards for a New Age

William H. Ailor received a Ph.D. in Aerospace Engineering from Purdue University. He joined The Aerospace Corporation in 1974 and spent the last 15 years conducting analyses on spacecraft reentry and reentry breakup. Ailor received a NASA Group Achievement Award in 1992 for his work in helping to understand the reentry breakup characteristics of the Space Shuttle External Tank. In 1997 he was appointed director of the newly formed Center for Orbital and Reentry Debris Studies. Ailor has appeared on NBC Nightly News, CBS Evening News, ABC News, CNN, as well as the Discovery Channel as an expert on the November 1998 Leonid meteoroid storm's possible effects on satellites, topics related to space debris and reentry breakup.
