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.

HiRISE 3D: Cliffs and Patterned Ground near Hellas Basin
There is basketball-like patterned ground here that also surrounds the steep, rocky cliffs.

HiPOD: An Inlet Valley to Jezero Crater
Our science goal is to study the fluvial bedforms in this inlet valley located to the west of Jezero. With stereo and a digital terrain model, we can obtain information about cross-sections in the topography.

HiRISE 3D: A Tyrrhena Terra Crater with Altered Minerals
Not much by way of an image rationale, but the bedrock and dark dunes in this 3D image are worth staring at for a while.

HiPOD: Crater on a Wrinkle Ridge
This observation can inform us about the impact cratering process here along this wrinkle ridge, as well as see if there are any flow ejecta on the side of the crater wall. We can also take a look at the topography of the wrinkle ridge and its direction and shape.

HiRISE 3D: Would You Land Here?
While it might look tempting, our 3D images of areas within potential landing ellipses can help us determine where safe places are for future missions.

HiPOD: Steep Southern Slopes
Slopes in southern Coprates Chasma, to be exact. We have very little existing imagery along this portion of Coprates’s south wall. This observation will fill in the gaps and get unique coverage as we also look for colorful slopes of mafic materials.

The Search For “Brain Coral” On Mars: It’s not just dried up lakes and river valleys that suggest the action of liquid water on the Martian surface, say planetary geologists.

HiRISE 3D: Streamlined Features in Olympica Fossae
Always a scenic target in a dusty region with few other good targets.

HiPOD: The Joy of Frost
We have imaged this area many times before, and like those previous observations, we want to monitor these very active polar pit gullies for frost and fresh deposits.

HIPOD: Wrinkles in Rock
The bedrock in this region of Arabia Terra has been worn away by the wind, revealing their internal structure and geologic history.
The wavy lines are individual layers of sand and dust, originally laid down as the bedrock was forming. These patterns indicate that the bedrock formed as layers of sand and dust lost their confrontation with the relentless Martian wind in a desert-like environment.

HiPOD: The Case of the Martian Boulder Piles
What organized these boulders into neatly-spaced piles? In the Arctic back on Earth, rocks can be organized by a process called “frost heave.” With frost heave, repeatedly freezing and thawing of the ground can bring rocks to the surface and organize them into piles, stripes, or even circles.
HiPOD: A Volcano of Mud or Lava?
This image shows a hill with a central crater. Such features have been interpreted as both mud volcanoes (really a sedimentary structure) and as actual volcanoes (the erupting lava kind). They occur on the floor of Valles Marineris below a closed topographic contour that could have held a lake, and the compaction of wet sediments may have created mud volcanoes.

HiPOD: Bedrock Exposed in the Rim of Hale Crater
Hale Crater is a large impact crater (more than 100 kilometers) with a suite of interesting features such as active gullies, active recurring slope lineae, and extensive icy ejecta flows. There are also exposed diverse (colorful) bedrock units.
Note: North is down, so that the slope is down to the bottom of the cutout and illumination from the upper right.

New Map Reveals Secrets of Io, the Solar System’s Most Volcanic Moon
The best-yet map of active volcanoes on Jupiter’s moon Io hints at a hidden magma ocean—and more
HiClip mini 4K: Ab antiquo
This observation was acquired to look at contact between light-toned deposits and chaos mounds. This is a non-narrated clip with ambient sound.
HiPOD: Rising above It in Amazonis Planitia
This image shows a bright, rectangular-looking landform surrounded by a dark floor. How did this feature get here if it looks so different than its surroundings?
The feature resembles a plateau. Dark streaks mark steep slopes on its sides while the top appears flat. The slope streaks are not all the same age, as we see a variation in colors from faint to dark.
HiPOD: A Fan with Inverted Channels
This image shows inverted channels within a fan whose origin could be either fluvial (produced by the action of a stream) or alluvial (created by sedimentary deposits).
If the fan is alluvial, then it formed on dry land. If the fan is fluvial, then it could have formed in water, like a delta.

HiPOD: Gullies in Ius Chasma
Pristine gullies are common on steep slopes in the middle latitudes of Mars, where they are shaped by the action of carbon dioxide frost. There are also pristine gullies in equatorial Valles Marineris where little carbon dioxide frost is deposited.
Atomic Oxygen Detected on Venus
New data provide direct evidence for the existence of atomic oxygen in Venus's upper atmosphere, enabling new science on our sister planet.
