| The Ripples of the Dunes
This observation overlaps with another image we acquired in 2009. In Mars Year 30 (approximately February 2010 to January 2012) six images were taken here to monitor gully formation. We want to learn how the ripples have moved since then. Have they erased the newly-formed gullies? Are we seeing a competition between wind, ice, and water here? |
| Layers in a Crater Wall in Bahram Vallis
The objective of this observation is to examine layers in a crater wall. There is a light-toned layer on top of a darker layer, and the boundary between them is quite sharp. Bharam Vallis drains from the higher elevations of Lunae Planum towards the Chryse Planitia basin. | 
| Wide Gullies in Terra Cimmeria
Also visible in Context Camera images, the objective of this observation is to examine a group of gullies that are quite wide, but have short channels, on the eastern side of an impact crater. Terra Cimmeria, in the heavily cratered Southern Highlands of Mars, is a region of interest because of Eridania, paleolake that existed during the early part of Mars’ past, when liquid water was abundant in the area. | 
| A Fluvial Valley in Arabia Terra
This observation features a fluvial channel and a possible palaeolake basin, the extent of which has been calculated based on outlet valley elevation. Further work requires high resolution observations to investigate possible small scale features including desiccation cracks and fine sedimentary layering. | 
| The Jewel in the Crater
This observation was requested to monitor frost deposition, evolution, and sublimation activity of this beautiful dune field at the bottom of an impact crater. This image will be used for detailed surface measurements, along with data from a requested ride-along by the Context Camera. Our picture overlaps with a previous one acquired in 2021. |
