Classroom Activity: Mapping Alien Worlds

A multi-layered surface is visible, composed of legos. The different colors relate to different surface elevations.

In this activity, students analyze simulated radar data to map surface elevations on a grid. Next, they determine what kind of surface feature is displayed by the data. Students then build a physical model representing their data.

Two engineers in full white body coveralls and masks are shown in the center of the image lifting a silver box up from a cart, revealing Europa Clipper’s surface dust analyzer instrument underneath. The engineers and the instrument are seen in a cleanroom. The instrument is surrounded by a semi-transparent protective plastic that is in the shape of the box that was covering it. The gold colored instrument is about the size of a drum.
