HiRISE: Hellas Planitia ridge network
A ridge network in Hellas Planitia. The objective of this observation is to examine a ridge network that seems to be forming from an upper layer of material. There are many exposures of ridges in this location, and this spot … Continue reading

HiRISE: Into the dune database
Into the dune database. Dunes are particularly suited to comprehensive planetary studies because they are abundant over a wide range of elevations and terrain types. Observations like this one are used to aid in classification and volume estimates of dunes … Continue reading

HiRISE: Narrow troughs
Narrow troughs. What exactly are the nature of these thin, narrow troughs? They might may be part of a system of dikes that came from the same magma source that fed the whole area in Thaumasia Planum, just south of … Continue reading

HiRISE: Wonderful world of Arabia Terra
The wonderful world of Arabia Terra. It’s one of our favorite regions, not the least because of the incredible layered sedimentary rock but also for the composition of the bedrock. Arabia Terra might be one of the oldest regions on … Continue reading

MARCI weather report, August 12-18, 2019
Afternoon weather conditions were very seasonal this past week. Local dust storms were observed along the seasonal receding north polar cap edge (north of Acidalia) and at southern low-latitudes (Margaritifer and Solis) and mid-latitudes (from Aonia to Cimmeria). Condensate clouds … Continue reading

HiRISE: Southeast Hale Crater ejecta
Southeast Hale Crater ejecta. This image can help us determine whether there are one or multiple ejecta lobes in this region. Hale Crater is often imaged by HiRISE for the presence of recurring slope lineae, or flows that may or … Continue reading

MARCI weather report, August 5-11, 2019
During the past week on Mars, transient dust storms were observed along the edge of the south polar hood in Sirenum and Aonia. While in the northern hemisphere, storms developed along the seasonal cap edge, with one arcuate-shaped storm propagating … Continue reading

HiRISE: Sedimentary infill
Interaction. This crater and many of those surrounding it are filled with layered sedimentary material. There are various theories for the origin of this layered fill, and this image will help to constrain the relationship of the fill to the … Continue reading

HiRISE: Before Jezero
Before Jezero. Before Jezero Crater was selected as the landing site for the Mars 2020 mission, this area in Gusev Crater was in the running. The terrain here is very different from nearby Columbia Hills (location of the Spirit rover), … Continue reading
