OVERVIEW:

The purpose of this workshop is to bring together the community of planetary scientists, spacecraft engineers, and mission designers and planners whose expertise, experience, and interests are in the area of entry probe trajectory and attitude determination, and the aerodynamics and measurement of the aerodynamical (aerothermodynamical) properties of planetary entry vehicles. The workshop will comprise presentations, posters, and discussions on the use of entry probe accelerometry and other techniques to reconstruct the entry and descent trajectory of entry probes. Issues to be addressed include methods, technologies, and algorithms currently employed, techniques and results from the rich history of entry probe science such as PAET, Venera/Vega, Pioneer Venus, Viking, Galileo, and Mars Pathfinder, upcoming missions such as Huygens, Netlander, and Beagle 2, and new and novel instrumentation and methodologies.

GOAL:

(1) To provide an important historical perspective on previous probe entry and descent trajectory reconstructions; and to develop the context within which current and future entry and descent trajectory analyses can be placed;

(2) To review the current state of the art, the instrumentation, methodologies, and algorithms currently in use, from conception to error recovery;

(3) To involve young scientists and engineers and promote continued development in the field of entry probe trajectory analysis, and to foster international collaboration in the field;

(4) Serve as a platform to initiate discussions of innovative methodologies and techniques for future entry probe missions.

TOPICS:

Topics appropriate for this workshop include Methods developed for entry and trajectory reconstructions for previous planetary entry probe missions, including Earth; Analysis techniques, limitations, and results. Instrumentation contributing to entry/descent trajectory analysis including (but not limited to) accelerometry, Pressure and Temperature measurements, radar altimeters, imaging, Doppler tracking, Probe Relay Link, etc. Entry and descent trajectory analysis planned for current and planned entry probe missions to Venus, Mars, Earth, and the outer planets and Titan. Entry and descent trajectory analysis on future missions Novel Techniques, algorithms, and instrumentation for probe entry and descent trajectory reconstructions Important
