HiRISE: Tooting Crater ejecta
In this picture we can see a huge tongue-like form, which looks a like a mudflow with boulders on its surface. This “tongue” is only a small part of a larger deposit that completely surrounds Tooting Crater (not visible in … Continue reading

HiRISE: Holden Crater impact ejecta
Holden Crater impact ejecta. Because Holden is such a massive crater (about 140-km in diameter), its ejecta certainly covers a wide area. This image focuses on a small portion of it, where we can see some diverse compositions. HiRISE Picture … Continue reading

THEMIS: Big impacts and little in Terra Cimmeria
THEMIS Image of the Day, March 13, 2019. This VIS image contains three craters. There is a quarter of the largest crater in the top half of the image, half of a smaller crater at the very top, and the … Continue reading

HiRISE: Colorful impact ejecta in Ladon Valles
This image covers the western portion of a well-preserved (recent) impact crater in Ladon Basin. Ladon is filled by diverse materials including chemically-altered sediments and unaltered lava, so the impact event ejected and deposited a wide range of elements. This … Continue reading

HiRISE: Ejecta margin near Ares Vallis
Ejecta margin near Ares Vallis. The objective of this observation is to examine the margin of a crater’s ejecta. The ejecta on this side looks different than on the opposite side. Ares Vallis is an outflow channel, likely carved by … Continue reading

HiRISE: Weathered ejecta and pitted material associated with Kontum Crater
Weathered ejecta and pitted material associated with Kontum Crater. Weathered, eroded, and scoured ejecta of Kontum Crater could expose ponded, pitted, and underlying material, as well as interesting contrasts. This image is right outside Kontum Crater on the eastern side. … Continue reading

HiRISE: Mars and the amazing Technicolor ejecta blanket
A close-up image shows the exposed bedrock of an ejecta blanket of an unnamed crater in the Mare Serpentis region of Mars. Ejecta, when exposed, are truly an eye-opening feature, as they reveal the sometimes exotic subsurface, and materials created … Continue reading

Impact-heated rock led to relatively recent water-carved valleys on Mars
New research shows that water from melted snow and ice likely carved valley networks around Lyot crater on Mars. Present-day Mars is a frozen desert, colder and more arid than Antarctica, and scientists are fairly sure it’s been that way … Continue reading
