Passadena, California – This audio diary is part of the Powerful Signals Radio Series. The Mars Reconnaissance Orbiter will bring back more information than all the previous Mars missions put together. In our first audio diary, we follow Tracy Drain, a systems engineer for the orbiter project, on the journey to launch...and the white knuckle wait to see if the project will reach orbit and be successful. We learn not only what Tracy does, but also a little about who she is, and how her personal and professional worlds come together. Claes Adreasson, Producer.
