Experiment: AO015

Experiment Title: Free-Flyer Biostack Experiment

Original Principal Investigator(s): Reitz, Dr. Gunther - Invest. Role: Present, Bucker, Horst - Invest. Role: Original,

Experiment Description:

Studies on the biological effectiveness of HZE particles (particles of high atomic number Z and high energy) and stars are necessary to confirm ground-based work, as well as to assess the biological effects of HZE particles not currently available from accelerators on Earth. Spaceflight experiments are required to analyze and evaluate the biological effects of the different species of HZE particles prevalent in space. In comparison with the Apollo lunar mission, the dosimetric data calculated for a 6-month flight of LDEF yields an increase in total dose of approximately 360 percent, in HZE particle fluence of approximately 200 percent, and in stars of even 2700 percent. Thus LDEF offers a unique opportunity to gather information on the effects of stars on biological matter.
