4th and 5th Grade Challenge Program students from Field-Stevenson and Grant-White became astronauts on a simulated NASA mission to Mars on November 16th.  Serving on both the Mission Control team and the Spacecraft team, students were in charge of running all aspects of the mission,  working hands-on with science experiments, and communicating with each other.  Before their voyage, students had to apply for their positions by completing an application about themselves.  There were various jobs that required specific skills to apply.  Based on their application, students were assigned to one of many teams: Probe, Medical, Communications, Life Support, Isolation and Life Support.  Each team had a role that was critical for the mission success.  Students had a great time and led a successful mission through their teamwork.
