The Guidance, Navigation, and Control Lead basically is in charge of all of the components to make sure the spacecraft is pointed where the scientists want it to be pointed.

Mathematical modelers use mathematics to create models that demonstrate complex processes or solve problems. Many mathematical modelers use their skills to create and animate 3D representations of their processes with the assistance of software technology. 

In this NASA-JPL lesson, students create a model of a volcano, produce and record lava flows, and interpret geologic history through volcano formation and excavation. 

Students model Earth's tectonic plate movement and explore the relationship between these movements and different types of volcanoes.
