Shape model and simulated surface features of Vesta

In the activity "Gravity Mapping: Measuring Mass Concentration," high school students use simulated, but realistic data that correlates with a shape model and simulated surface of Vesta. These data include the latitude and longitude coordinates of data points at which a change in the line-of-sight velocity of the spacecraft was determined by Doppler shifts.

By mapping and connecting data points having the same velocity, students can identify areas of relatively high and low mass concentrations. Gravity Measurement includes a Teacher Guide, Student Activity, Student Text, and PowerPoint.

Dawn gravity scientist, Dr. Sami Asmar, unpacks gravity's big ideas in his engaging interview.
