HiRISE: Layers in Danielson Crater
This image shows sedimentary rock and sand within Danielson Crater, an impact crater 67 kilometers in diameter, located in the southwest Arabia Terra region of Mars. The rock was formed millions or billions of years ago when loose sediments settled … Continue reading

MARCI weather report, August 26-27, 2019
Weather patterns were fairly typical last week for this time of Mars year. In the north, local-scale dust storms were spotted along seasonal north polar cap edge. Diffuse water-ice clouds associated with the aphelion cloud-belt continued to be more dominant … Continue reading

HiRISE: Frost highlights in springtime
This image of a crater rim strikingly shows what appear to be bright white flows coming from gullies in the crater wall. However, HiRISE has been watching these gullies for some time (going all the way back to our first … Continue reading

MARCI weather report, August 19-25, 2019
Afternoon weather conditions were again very seasonal this past week. Local dust storms were observed along the seasonal receding north polar cap edge and at southern low-to-mid latitudes. The developing aphelion cloud belt continued to be prominent at equatorial latitudes. … Continue reading

HiRISE: Bedrock riddles of Nili Fossae
This image of the Nili Fossae region, to the west of the great Isidis basin, shows layered bedrock with many impact craters. Nili Fossae is one of the most mineralogically important sites on Mars. Remote observations by the infrared spectrometer … Continue reading

HiRISE: Avalanche season
Every spring the sun shines on the side of the stack of layers at the North Pole of Mars known as the north polar layered deposits. The warmth destabilizes the ice and blocks break loose. When they reach the bottom … Continue reading

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
