LPI Senior Staff Scientist Paul Schenk has created a new online exhibit that illustrates his work using topography to investigate icy ocean worlds of our solar system. The best tool for mapping the topography of icy moons and planets is stereo imaging, which Dr. Schenk uses to derive measurements of planetary surface elevations. These measurements help us understand how the surfaces have evolved over time and have led to discoveries such as the large kilometer-deep depressions (or “dimples”) on Enceladus. The exhibit Using Topography to Investigate Icy Ocean Worlds can be found on the LPI website in the online research gallery.
