Dr. Joseph P. Martin, Chief Scientist

Dr. Martin joins us after a distinguished career at LMA. A Lockheed Martin Astronautics (previously Martin Marietta) scientist for 39 years has developed space science instrumentation for many space and planetary programs. He retired from LMA April 2000.

He managed a U of Arizona Planetary Instrument Definition and Development (PIDDP) program developing a thermal and evolved gas analyzer for mars landers. He managed a PIDDP imaging Fourier transform interferometer development with U Wisc. He led the initial development of the Imager for Mars Pathfinder (IMP) with the U AZ. He managed the proposal to develop the full science payload for the Mars Polar Pathfinder Discovery proposal for a north polar lander and subsurface science mission teamed with UCLA and JPL. He has supported the instrument payload for the NASA/ARC Hummingbird Discovery mission proposals for a comet rendezvous and touchdown sampling mission. He manged the proposal to MIT which resulted in LMA development of the the Advanced X-ray CCD Imaging Spectrometer (ACIS) on the Chandra X-ray astronomy mission. He also managed the proposal to the University of Arizona which resulted in LMA development of the Descent Imager Spectral Radiometer (DISR) which is on its way to descend into the atmosphere of the Saturn moon, Titan, on the Cassini/Huygens probe.

Dr. Martin led the LMA program to put together an integrated computer and power system for miniaturization and simplification of space science payloads. This included development of a power distribution module and input/ouput module in Lockheed Martin's High Density Interconnect (HDI) ultraminiature mutichip module technology. It also included an FPGA based multichannel direct memory access (DMA) with capability of performing operating control functions and data collection functions for an entire payload as well as for spacecraft operational functions, allowing the single CPU to operate an entire spacecraft and payload. He also provided the leadership that led to a SBIR contract to Performance Software to develop the software for instrument development and automated flight software coding for the integrated computer and power sysem for a science payload called Central Instrumenty Controller (CIC).

Dr. Martin was PI for Lockheed Martin Advanced Instrument Technology IR&D program, with recent development of a miniature universal FPA driver module, a Focal Plane Array (FPA) test facility, blackbody in-situ calibrator, development of black surfaces, comet dust velocity analyzer, sensor electronic circuits, concept for XRD/XRF with CCDs, IR detector testing and modeling, Multiple Quantum Well LWIR array testing, InGaAs array tests, Z-plane focal plane array for a lightning mapper, scan mirror life test, beamsplitters and filters design, pointing mirror jitter control, logarithmic 12-bit A/D converter, imaging spectrometer modeling, passive radiative detector cooler, polarization minimization in near IR/visible scanning radiometer, pyrolysis oven for planetary analysis, planet sample collection drill.

Dr. Martin directed a geosynchronous lightning mapper development using Z-plane focal plane technology. He developed the axicon mirror & deployment for the very successful Galileo Jupiter Probe Nephelometer. He demonstrated a new approach to differential radiant flux measurements that was used on the Galileo Jupiter Net Flux Radiometer. He developed a unified chemical and soil analyzer for Mars using a mass spectrometer to sample trace gas evolution in 11 sealed test cells. He led the early Solar Wind Analyzer design for ISPM. He measured neutrons in space produced by cosmic ray collisions in the earth's atmosphere as a function of magnetic latitude. He developed technology for generating and propagating microwave ultrasonic waves in crystals at cryogenic temperatures.
