HiRISE (NASA)
HiRISE is a high resolution camera onboard the Mars Reconnaissance Orbiter (NASA). We take images of the surface of Mars. Based out of UArizona in Tucson.

Noachian Bedrock Diversity
In an adjacent image we acquired in 2008, there was terrific color and texture diversity, so this observation was acquired to extend coverage. There are clays mixed with unaltered mafics in this area as well. “Noachian” refers to the early geologic period after Mars formed, 3 to 4 billion years ago.

HiRISE 3D: Terracing Inside and Outside a Degraded Crater Rim
This image shows multiple bands on the inside and outside of a crater rim that may be terraces. Are they paired topographically?

HiRISE 3D: A Buffet of Secondary Craters
This observation is part of a study that aims to characterize how secondary crater shape depends on distance from source craters and hence impact velocity.

HiRISE 3D: A Possible Fresh, Small Crater in Arcadia Planitia
With this anaglyph, we can look for rocks, textures and excavated stratigraphy.

The people have spoken!
It seems we will keep our sternly-worded memo on file and just post our 3D pics without further ado.
Thanks, everyone!
It seems our lazy, good-for-nothing social media guy hasn't posted any 3D pics in several days. Should we:
HiPOD: Colorful Impact
Our enhanced image reveals colors ranging from red to green to blue. These are infra-red shifted colors (infrared-red-blue) so it’s different than what we would see with our eyes.
HiPOD: Seasonal Flows in the Central Mountains of Hale Crater
The recurring slope lineae (RSL) in Hale have an unusually “reddish” color compared to most RSL, perhaps due to oxidized iron compounds, like rust. Since HiRISE color is shifted to infra-red wavelengths, they are actually especially bright the near-infrared just beyond the range of human vision.
HiPOD: Layering in Spallanzani Crater
In this image, we can see quite a spectacular layering pattern inside an impact crater called Spallanzani. Seeing layering is always exciting to geologists because it implies that the region has experienced multiple climatic conditions or geologic processes through time.
HiRISE 3D: Dunes in 3D
These dunes are also visible in MOC images.

HiPOD: Yardangs in Arsinoes Chaos
The slightly curving, sublinear bright terrain is composed of yardangs. Yardangs are portions of rock that have been sand blasted into long, skinny ridges by saltating (or bouncing) sand particles blowing in the wind.
HiPOD: A Polar Smile
This image represents one of many monitoring sites at the South Pole residual cap (SPRC). Images are taken throughout the Martian year to document changes in carbon dioxide ice coverage.
This image shows a popular spot where one of the features resembles a smiley face that is approximately 500 meters across. If you smile at Mars, sometimes it smiles back.

HiRISE 3D: Crater Ejecta Crosscut by Channels in Aeolis Dorsa
One of our goals is to seek confirmation of multiple episodes of flow: are the channels filled by fluvial materials, debris flows, or something else?

HiPOD: Valleys in Deltoton Sinus
The objective of this observation is to examine valleys on the wall of an old crater. These valleys are wide, and then they get narrow and become very steep. There may have been waterfalls here. The scene can be found in Context Camera data. The name means “bay of the triangle” and its location makes triangle with Iapygia and Oenotria.

HiRISE 3D: Ridges on the Floor of Shalbatana Vallis
These curved ridges are real, and they’re spectacular!

HiPOD: In an Unnamed Crater
Also available in Context Camera data, we acquired this observation to examine gullies in a small, southern mid-latitude crater. Images like this one will help us increase our inventory of Martian gullies. This scene is located in Terra Sirenum, in the Southern Hemisphere of Mars.

HiRISE 3D: Layered Late-Stage Fan in Gale Crater
Our rationale is to search for boulders for comparison to Gediz Vallis ridge currently adjacent to the Curiosity rover.

HiPOD: This is Not Hadrian’s Wall
This observation shows us a spectacular long-running ridge located to the north of Vernal Crater. These ridges may be large, mineralized fracture zones. This image was requested to investigate further and take a look at the structure within the ridge, especially with a digital terrain model to help. (Black and white cutout is less than 5 km across; enhanced color is less than 1 km across.)

HiRISE 3D: At the North Pole
This observation was requested to re-image for potentially active tectonic activity that we can compare to a previous image in 2008.
