THEMIS: Near the river

Near the river (THEMIS_IOTD_20190301)THEMIS Image of the Day, March 1, 2019. This false color image contains several channel features. Towards the top of the image are several stream-lined islands, created by liquid flow eroding preexisting rock. The islands have a tear-drop shape, with the pointy end down stream from the rounded end.

In this case the fluid flowed from the bottom right of the frame towards the upper left. Just below the center of the image is a larger, deeper channel. All these channel features merge into Ares Vallis, a huge outflow channel that empties into Chryse Planitia.

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.
