HiRISE: Channel system & patterned ground near Hellas
In this image, we explore the southwestern floor of a 50-kilometer diameter unnamed crater, about 100 kilometers northeast of Hellas Basin. The crater’s rim is breached (see Google context image below) on both the north and south by a valley … Continue reading

HiRISE: Searching for clinoforms in a possible delta
A delta is a pile of sediment dumped by a river where it enters a standing body of water. Evidence for deltas that formed billions of years ago on Mars has been mounting in recent years. One line of evidence … Continue reading

THEMIS: Channel and delta
THEMIS image of the Day, July 1, 2015. This VIS image shows two channels. The channel in the center of the image ends in a crater, where it has created a delta deposit. These unnamed craters and channels are located … Continue reading

HiRISE: Fill or mantling material in a crater
This observation targets some unknown fill or mantling material within valleys on a crater floor and within a central pit. High resolution imagery can help determine what this material may be (e.g., ice-rich fill, dust, or other mantling unit?) and … Continue reading

HiRISE: Sinuous ridge on Orson Welles bajada
Alluvial fans are piles of debris dumped by rivers when they emerge from the mountains and enter a mostly dry valley. A bajada (such as this example named after the famous American filmmaker) consists of a series of coalescing alluvial … Continue reading

HiRISE: Embayment in tectonized fluvial terrain
This highly tectonized terrain (meaning it possesses many faults) has its low-lying areas filled with some form of younger material. This particular fill is what geologists call “embayment.” This observation helps scientists unravel the relative timing of the emplacement of … Continue reading
