HiRISE: A sneak peek into Saheki’s secret layers
Saheki Crater is large, about 84 kilometers across, and located in the Southern highlands of Mars, to the north of Hellas Planitia. It’s filled with beautiful alluvial fans that formed when water (likely melting snow) carried fine material, such as … Continue reading

Karun Valles & its braided alluvial fan
Planetary Geomorphology Image of the Month, September 29, 2016: Solmaz Adeli (DLR, Institute of Planetary Research, Berlin). The Amazonian period on Mars, meaning roughly the last 3 Ga, is globally believed to have been cold and hyperarid [e.g., Marchant and … Continue reading

HiRISE: Alluvial fan stratigraphy in Saheki Crater
Alluvial fans are gently-sloping wedges of sediments deposited by flowing water. Some of the best-preserved alluvial fans on Mars are in Saheki Crater, an area that we’ve imaged many times previously. This observation covers two impact craters that expose the … Continue reading

Curiosity: Locating RMI’s ‘distant deposits’
Sol 1264, February 25, 2016. The red boxes on two Navcam images outline the locations of two recent RMI mosaics seen here. Taken at long range by the rover’s Remote Micro-Imager, the mosaics show deposits far away to the north … Continue reading

Curiosity: Looking at distant deposits
Sol 1263, February 24, 2016. The ChemCam’s Remote Micro-Imager shot two long-range, multi-frame views showing features of the terrain at the foot of Gale Crater’s rim. One series of images centers almost due north (above, toward 355°), the other northwest … Continue reading

HiRISE: A possible alluvial fan
This image shows the northern rim of a crater in Deuteronilus. At the northern end, we see the crater rim and ridges inside and below that rim. A channel set is entering from the west and passing through a notch … Continue reading

Curiosity update: CHIMRA diagnostics
Sol 1237-38, January 27, 2016, update from USGS scientist Ken Herkenhoff: The cause of the CHIMRA anomaly is still being investigated, so no arm motion was planned today while diagnostic testing continues. Because only remote science observations are allowed, it … Continue reading
