THEMIS: Crazy craters
THEMIS Image of the Day, June 19, 2019. Today’s VIS image shows two craters located on the margin of Syrtis Major Planum. The two large craters are not circular. The flatter sides are caused by the pressure wave generated by … Continue reading

THEMIS: Wind streaks on northern plains
THEMIS Image of the Day, April 12, 2019. Today’s false-color VIS image is located in the plains between Chryse and Acidalia Planitias. Dark blue tones in this false color combination are usually created by basaltic sands. There appears to be … Continue reading

Winds of Jezero Crater
[Editor’s note: From a paper by Mackenzie Day and Taylor Dorn recently published in Geophysical Research Letters.] Wind in Jezero crater, Mars • Modern winds in Jezero crater come from the east, but ancient winds came from the southwest • … Continue reading

HiRISE: Streaking on Mars
Streaking on Mars. Wind streaking, that is. Here’s the suggester’s rationale for acquiring this image: “There’s a field of two-tailed bright wind streaks here that are really neat. They seem unique to the area. It would be nice to get … Continue reading

THEMIS: High on the east flank of Pavonis Mons
THEMIS Image of the Day, October 11, 2018. This false-color VIS image shows the eastern flank of Pavonis Mons. The darker streaks are created by wind action, and the curving lines are faults produced when the volcano “relaxed” under the … Continue reading

THEMIS: Wind streaks in Terra Sirenum
THEMIS Image of the Day, August 28, 2018. This VIS image shows a small region in Terra Sirenum. The bright material forming “tails” behind the craters were created by surface winds funneled over and around the crater. The raised rims … Continue reading

THEMIS: Lava flows chopped by graben in Olympica Fossae
THEMIS Image of the Day, May 21, 2018. The linear channel in the bottom half of this VIS image is part of Olympica Fossae. Olympica Fossae is a complex channel form located on the Tharsis plains between Alba Mons and … Continue reading

HiRISE: Pettit Crater wind streak and intracrater dunes
Pettit Crater wind streak and intracrater dunes. Part of the rationale for this observation is to look for dune bedforms that may be related to thermal inertia and particle mobility. This crater was named after Edison Pettit, an American astronomer (1890–1962). … Continue reading

THEMIS: A peppering of small craters
THEMIS Image of the Day, April 4, 2018. This field of small dark craters is located in southern Elysium Planitia. The dark appearance against the surrounding lava flows suggests that the craters post-date the lava flows. The small “tails” near … Continue reading

THEMIS: Dunes and wrinkle ridge, Meroe Patera
THEMIS Image of the Day, October 26, 2017. This image shows part of the dune field near Meroe Patera. High resolution imaging by other spacecraft has revealed that the dunes in this region are moving. Winds are blowing the dunes … Continue reading
