High school students in computer graphics courses at Mountainland Applied Technology College are helping a NASA mission to Mars. “I’m excited but a little nervous,” said Shaun Watson, 17, a Provo High School senior. “It’s going to be so big and everyone’s going to be relying on us.” Students in two MATC multimedia courses will serve as one of 54 Mars Exploration Student Data Teams, assisting NASA as two rovers launched last summer land on the red planet in January and begin exploring.
