Bigbee is a 21 kilometer-diameter impact crater located on the northern rim of Holden crater in southern Margaritifer Terra, a region on Mars that is well known for its long record of water-rich activity as seen by NASA's Mars Reconnaissance Orbiter.
Taken in late southern spring and when Mars is near perihelion (closest distance to the Sun), this image from NASA's Mars Reconnaissance Orbiter shows the effects of dry ice sublimation on a longitudinal dune in the far Southern hemisphere.
NASA's Curiosity Mars rover can be seen at the 'Pahrump Hills' area of Gale Crater in this view from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter.
The dark fans in this image are made up of small particles from the surface deposited on top of the seasonal layer of ice; carbon dioxide ice still covers much of the surface at this high latitude site observed by NASA's Mars Reconnaissance Orbiter.
This image from NASA's Mars Reconnaissance Orbiter shows two small craters (called 'tangential craters'), just touching on their rims, in the much larger Ptolmaeus Crater, which is located in the Martian Southern hemisphere.
The pits visible in this image from NASA's Mars Reconnaissance Orbiter aren't impact craters. The material they are embedded into is ejecta (stuff thrown out of an impact crater when it forms) from a large crater called Hale not seen in this image.
In this observation from NASA's Mars Reconnaissance Orbiter made for a study of ancient craters, we see the craters filled with smooth material that has subsequently degraded into scallops. These formations might be possibly due to ground ice sublimation.
The terrain in this observation from NASA's Mars Reconnaissance Orbiter looks like an ancient uplifted crustal block. The area is riddled with faults (big cracks that allow rocks to slide) and ridges that look like uncovered magma dikes.
NASA's Mars Reconnaissance Orbiter observes the southeast rim of Hale Crater, about 150 kilometers (90 miles) in diameter and located in the mid-southern latitudes just north of the massive Argyre basin.
NASA's Mars Reconnaissance Orbiter observes a group of small gullies along a rock layer on the south wall of Liu Hsin Crater. At the foot of the gullies 'fans' of granular sediment have been deposited downhill from the gully formation.
This image from NASA's Mars Mars Reconnaissance Orbiter shows a triple impact crater in Elysium Planitia near Tartarus Montes, which probably formed when a binary-or even triple-asteroid struck the surface.
A configuration interpreted as the United Kingdom's Beagle 2 Lander, with solar panels at least partially deployed, is indicated in this composite of two images from NASA's Mars Reconnaissance Orbiter.
This annotated image, taken in 2014, shows where features seen in an observation by NASA's Mars Reconnaissance Orbiter have been interpreted as hardware from the Dec. 25, 2003, arrival at Mars of the United Kingdom's Beagle 2 Lander.
There are many knob formations is the southeastern Acidalia region of Mars. All show a hilltop crest except one which has a summit crater that resembles a cone volcano in this image captured by NASA's Mars Reconnaissance Orbiter.
This channelized area is near the source region of the huge outflow channel, Ares Vallis. It was at the distal end or 'long-ways down-river-area' where the Pathfinder/Sojourner mission landed on 4 July 1997.
Visible in this observation from NASA's Mars Reconnaissance Orbiter is a section of Cerberus Fossae, which are comprised of a series of rifts present located in Elysium Planitia just north the Martian equator.
