HiRISE: Raindrops of sand in Copernicus Crater
Raindrops of sand in Copernicus Crater. The dark features here look like raindrops, but are actually sand dunes rich in the mineral olivine. These types of dunes are rare on Earth as olivine rapidly weathers to clays in a wet … Continue reading

HiRISE: Stairway to Danielson
Stairway to Danielson. Previous images showed possible recurring slope lineae here in Danielson Crater. Additional images are needed to confirm their existence, but it’s the stair-stepped layers that also capture our attention for their stark beauty. HiRISE Picture of the … Continue reading

HiRISE: Two flows
Two flows. The objective of this observation is to examine two flows near the base of a mound. There seem to be a number of flows like these in the region. Reull Vallis is believed to have formed when running … Continue reading
HiRISE: A beveled circular feature
A beveled circular feature. This very interesting, beveled and flat circular surface is surrounded by craters. It is itself a pedestal crater or could it be a small ancient volcano? High resolution can afford us a closer look at the … Continue reading

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

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
