THEMIS: Bonestell Crater in false color

Bonestell Crater in false color (THEMIS_IOTD_20190419)THEMIS Image of the Day, April 19, 2019. Today’s false-color image shows part of Bonestell Crater. This is a relatively young crater located in Acidalia Planitia.

Dust blown into the crater and the downslope movement of fine materials from the rim are slowly modifying the crater features. This material is responsible for the sand dunes visible at the bottom of the image. Dark blue tones in this false color combination typically indicate basaltic materials.

The THEMIS VIS camera contains 5 filters. The data from different filters can be combined in multiple ways to create a false color image. These false color images may reveal subtle variations of the surface not easily identified in a single band image.
