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: Flow, moving
Flow, moving. The objective of this observation is to examine a flow that goes through a crater in Nilosyrtis Mensae. It was probably larger in the past and has since been reduced in volume. HiRISE Picture of the Day archive. … Continue reading

HiRISE: Floor and north rim of Dokka Crater
Floor and north rim of Dokka Crater. Dokka Crater is 52-kilometers in diameter and located in the north polar region of Mars. Its interior is presumably a remnant of a former polar cap with larger extension, so it could provide … Continue reading

Do ice-squeezed aquifers cause marsquakes?
As the Mars InSight lander begins listening to the interior of Mars, some scientists are already proposing that some marsquakes could be signals of groundwater beneath the frozen surface of the Red Planet. The idea, proposed by Michael Manga, a … Continue reading

THEMIS: South polar layers
THEMIS Image of the Day, June 14, 2019. This VIS image shows part of the south polar cap. The numerous layers that comprise the polar cap are readily visible. The cap was built up over millions of years of deposition … Continue reading

HiRISE: Still life with an impact crater
Still life with an impact crater. Ice fill within a crater in the north polar layered deposits (NPLD) may be a site where accumulation could be observed, helping to settle a long-term problem in Mars polar science: are the NPLD … 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
