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
THEMIS: Northern Arabia Terra channel
THEMIS Image of the Day, August 8, 2019. The margin between Arabia Terra and the surrounding lowlands is dissected by numerous named and unnamed channels. Today’s VIS image shows part of an unnamed channel in the region. The channel floor … Continue reading

HiRISE: A fresh crater in periglacial terrain
A fresh crater in periglacial terrain. This appears to be a relatively fresh crater in what is called periglacial terrain. Could any changes in the surface be related to ice? (Periglacial refers to an area adjacent to a glacier or … Continue reading

HiRISE: Mounds in depressions in Deuteronilus Mensae
Mounds in depressions in Deuteronilus Mensae. The objective of this observation is to determine the nature of round mounds in depressions. The depressions may be part of the ribbed upper plains unit. Some of the edges of the depressions are … Continue reading

HiRISE: Quite smoooooth
Quite smoooooth. Here in Deuteronilus Mensae, there is a smooth geologic unit overlying plains material. There are also slightly convex-up edges, polygonal patterns on the surface, and softened craters. HiRISE Picture of the Day archive. [More at links]
THEMIS: Northern Terra Sabaea in false color
THEMIS Image of the Day, March 25, 2019. This false-color VIS image shows part of northern Terra Sabaea. Blue tones in false-color images usually indicate basaltic sand. The THEMIS VIS camera contains 5 filters. The data from different filters can … Continue reading

THEMIS: Bumpy hills of Arianes Colles
THEMIS Image of the Day, March 18, 2019. Today’s VIS image shows part of Ariadnes Colles. The term colles means hills or knobs. The hills appear brighter than the surrounding lowlands, likely due to relatively less dust cover. Ariadnes Colles … Continue reading

HiRISE: The slow charm of brain terrain
You are staring at one of the unsolved mysteries on Mars. This surface texture of interconnected ridges and troughs, referred to as “brain terrain” is found throughout the mid-latitude regions of Mars. (This image is in Protonilus Mensae.) This bizarrely … Continue reading

THEMIS: Acidalia Colles in false color
THEMIS Image of the Day, March 4, 2019. This VIS image shows part of Acidalia Colles. The term colles means hill. Dark blue tones in this band configuration typically identify basaltic sands. This “blue” material is found on the plains, … Continue reading

THEMIS: Protonilus Mensae in false color
THEMIS Image of the Day, February 28, 2019. The hills in this false-color VIS image are part of Protonilus Mensae. These hills, located between the relative highlands of Terra Sabaea and the lowlands of Vastitas Borealis, most likely formed by … Continue reading
