Magnetic Device Design and Evaluation Capabilities at JPL

This viewgraph presentation describes the magnetic device design and evaluation capabilities at the Center for Space Microelectronics Technology at the Jet Propulsion Laboratory. The capabilities start with supercomputers for design and simulation. Circuits can be examined via electrical flow and microscopic examination. These capabilities are useful for developing new devices, particularly for space applications.

Short-Period Seismometer Development at JPL

Determining the structure of the interior of Mars has been a high priority for every Mars exploration strategy developed in the past 20 years, and is one of the primary goals of the InterMarsnet mission. Seismology is by far the most effective and detailed tool for investigating the radial and lateral distribution of density and elastic properties within a planet. Whereas long-period signals contain information from surface waves and normal modes from relatively large events, as well as the tidal response of the planet, the ability to record the high-frequency portion of the seismic spectrum (0.05 > f > 50 Hz) is essential for using the body waves of small to moderate events for probing the interior and analyzing the source characteristics of martian quakes.

JPL Rover Technology Program

NASA has embarked on a new mission concept for its planetary program. This new mission concept calls for smaller, lower mass, cheaper systems. The Mars Pathfinder micro rover mission scheduled for launch in 1996 embodies this new mission concept.

Space Telerobotics and Rover Research at JPL

The goal of our program is to develop, integrate and demonstrate the science and technology of remote telerobotics leading to increases in operational capability, safety, cost effectiveness and probability of success of NASA missions. To that end, the program fosters the development of innovative system concepts for on-orbit servicing and planetary surface missions which use telerobotic systems as an important central component. These concepts are carried forward into develoments which are used to evaluate and demonstrate technology in realistic flight and ground experiments.
