MUNCIE, Ind. -- Reporters are invited to campus Sept. 12 for a media briefing with two American astronaunts who conducted in-flight research on a Ball State University experiment.

Astronauts Charles (Chuck) Brady Jr. and Richard Linnehan will review their 1996 flight that carried an experiment for Ball State's Human Performance Laboratory.

They also will address BeneFacta Day honorees and participants at 3 p.m. in the L.A. Pittenger Student Center Cardinal Hall.

A media briefing with the astronauts and researcher David Costill, director of the Human Performance Laboratory, begins at 2 p.m. Please report to the Human Peformance Laboratory in the Health and Physical Activity Building, located on McKinley Avenue adjacent to University Arena.

During the flight, payload specialists worked with Costill in determining the effects of microgravity on human muscles. Shuttle mission specialists used an exercise machine to measure calf strength during spaceflight. Brady and Linnehan later had muscle biopsies taken by Costill.

The presentation by Brady and Linnehan is a result of Ball State's partnership with the Indiana Space Grant Consortium, sponsored by the National Aeronautics and Space Administration. The consortium has created 13 Ball State faculty projects. Representatives from other Indiana Space Grant Consortium universities and colleges will attend the event.
