ATI's Space Radiation & It's Effects On Space Systems & Astronauts course


Share |

Summary:

Technical Training Short On Site Course Quote

This course is designed for technical and management personnel who wish to gain an understanding of the fundamentals and the effects of space radiation on space systems and astronauts. The radiation environment imposes strict design requirements on many space systems and is the primary limitation to human exploration outside of the Earthís magnetosphere. The course specifically addresses issues of relevance and concern for participants who expect to plan, design, build, integrate, test, launch, operate or manage spacecraft and spacecraft subsystems for robotic or crewed missions. The primary goal is to assist attendees in attainment of their professional potential by providing them with a basic understanding of the interaction of radiation with non- biological and biological materials, the radiation environment, and the tools available to simulate and evaluate the effects of radiation on materials, circuits, and humans.

Instructor:

    Dr. Vincent L. Pisacane was the Robert A. Heinlein Professor of Aerospace Engineering at the United States Naval Academy where he taught courses in space exploration and its physiological effects, space communications, astrodynamics, space environment, space communication, space power systems, and the design of spacecraft and space instruments. He was previously at the Johns Hopkins University Applied Physics Laboratory where he was the Head of the Space Department, Director of the Institute for Advanced Science and Technology in Medicine, and Assistant Director for Research and Exploratory Development. He concurrently held a joint academic appointment in biomedical engineering at the Johns Hopkins School of Medicine. He has been the principal investigator on several NASA funded grants on space radiation, orbital debris, and the human thermoregulatory system. He is a fellow of the AIAA. He currently teaches graduate courses in space systems engineering at the Johns Hopkins University. In addition he has taught short courses on these topics. He has authored over a hundred papers on space systems and bioastronautics.
