Space Mysteries  Chris Egbert  Jon Pruett

If you were in space… Would this really happen?

The Idea  Hollywood films have always incorporated science in their productions. However, the question that always seems to arise is, how accurate are these scientific features?  The clip shown, from the movie “Mission to Mars” depicts a body that is instantly frozen in space. Using knowledge acquired in Heat Transfer class, our group will demonstrate the accuracy of the scene.  Hollywood films have always incorporated science in their productions.
