The collapse features in this images are related to lava tubes that likely originated at Elysium volcanic complex

The collapse features in this image captured by NASA Mars Odyssey are located in the volcanic flows south of Alba Mons.

The collapse valleys in this portion of the floor of Bernard Crater were likely caused by the formation of Memnonia Fossae, a system of tectonic graben, that passes through the region. This image was captured by NASA Mars Odyssey.

The depressions in this image from NASA Mars Odyssey likely formed due to both volcanic and tectonic forces. Tectonic forces likely account for some of the depressions, while collapse into lava tubes and lava flow erosion account for the remainder.

Several sites of cliff collapse on comet 67P/Churyumov-Gerasimenko were identified during Rosetta's mission. The yellow arrows mark the fractures where the detachment occurred. The collapsed sections are about 50 feet (15 meters) long for the left-hand section, and 30 feet (9 meters) for the right-hand section. Additional images taken from greater distances suggest the collapse occurred between May and December 2015. The images were taken by Rosetta's OSIRIS camera on Dec. 2, 2014 (left), and March 12, 2016 (right), with resolutions of 1.6 feet (0.5 meters) per pixel and 1 foot (0.3 meters) per pixel, respectively. http://photojournal.jpl.nasa.gov/catalog/PIA21564

This image shows a set of coalesced collapse pits in western Valles Marineris as seen by NASA Mars Reconnaissance Orbiter. Fine layers are exposed in the walls of the pits, and in some places those layers are displaced by faults.

This image from NASA's Mars Reconnaissance Orbiter (MRO) shows the eastern rim of a small 3.5-kilometer crater which appears to have collapsed into a much larger crater (about 14-kilometers wide). The larger crater has a large ice flow around its central peak, and is non-circular, with large blocks further suggesting structural collapse of the terrain due to what are called periglacial processes. Understanding the composition of this small crater may inform us of the ice content of the surrounding terrain. The map is projected here at a scale of 50 centimeters (19.7 inches) per pixel. [The original image scale is 50.8 centimeters (20 inches) per pixel (with 2 x 2 binning); objects on the order of 152 centimeters (59.8 inches) across are resolved.] North is up. https://photojournal.jpl.nasa.gov/catalog/PIA22116

North of Ganges Chasma lies Orson Welles Crater, whose floor contains broken up blocks we call chaotic terrain and which is the source for the major outflow channel Shalbatana Vallis. Between Orson Welles and Ganges Chasma is a region where materials subsided and collapsed over underground cavities that had once held aquifers. This image shows an elongated collapse pit. There is evidence that the pit was once filled with water as the groundwater erupted to the surface. A closer view shows fine sedimentary layers exposed by erosion. https://photojournal.jpl.nasa.gov/catalog/PIA25082

Do you see a dome or a pit? Sometimes it is hard to tell! In this case, the answer is that we're looking at a pit, if the title didn't already give it away. Levity aside, we can tell this is a pit because we know what direction the sunlight is coming from and which side should be in shadow. This pit has formed on the south polar layered deposits. Why did it collapse? That is the real question to be answered. https://photojournal.jpl.nasa.gov/catalog/PIA24614

This image from an animation shows a gigantic star exploding in a "core collapse" supernova. As atoms fuse inside the star, eventually the star can't support its own weight anymore. Gravity makes the star collapse on itself. Core collapse supernovae are called type Ib, Ic, or II depending on the chemical elements present. Stellar explosions forge and distribute materials that make up the world in which we live, and also hold clues to how fast the universe is expanding. By understanding supernovae, scientists can unlock mysteries that are key to what we are made of and the fate of our universe. But to get the full picture, scientists must observe supernovae from a variety of perspectives, especially in the first moments of the explosion. That's really difficult -- there's no telling when or where a supernova might happen next. An animation is available at https://photojournal.jpl.nasa.gov/catalog/PIA22350

These lava flows and collapse features are part of Ascraeus Mons

STS049-71-042 (8 May 1992) --- This photograph, taken from the Earth-orbiting Space Shuttle Endeavour, shows a collapsed thunderstorm in the southwestern Pacific Ocean. The clouds were pushed from this circular area of the ocean's surface by relatively cool air that spread downward and outward from a dying thunderstorm. Around the edges of the downdrafted air, new, though smaller, storms are developing. The photo was taken on May 8, 1992, between Borneo and the Philippine island of Mindoro. Two coral atolls can be seen near the center of the photograph. The crew members used a handheld Hasselblad camera, 250-mm lens, color film to expose the image.

On July 17, 2016, one of the largest ice avalanches ever recorded tumbled down a Tibetan mountain, killing 9 people. The cause of the collapse is still unclear. On September 22, a second glacier, 1.9 miles (3 kilometers) farther south, collapsed. Geologists investigating the July collapse warned about the possibility of a second collapse, which did occur. The image covers an area of 7.8 by 10.2 miles (12.6 by 16.4 kilometers), was acquired October 4, 2017, and is located at 334 degrees north, 82.3 degrees east. http://photojournal.jpl.nasa.gov/catalog/PIA21069

This image shows a collapse feature on the southeastern flank of the volcano. The circular/scalloped margin of the collapse is typical for ceiling collapse into a lava tube. However, the potential lava tube is perpendicular to the surface flows. The linear nature and relationship to the surface flows likely indicate that a preexisting tectonic graben occurred here and hosted lava flows that may have become lava tube flows. So in this case, the collapse feature formed by a combination of tectonic and volcanic processes. The Odyssey spacecraft has spent over 15 years in orbit around Mars, circling the planet more than 69000 times. It holds the record for longest working spacecraft at Mars. THEMIS, the IR/VIS camera system, has collected data for the entire mission and provides images covering all seasons and lighting conditions. Over the years many features of interest have received repeated imaging, building up a suite of images covering the entire feature. From the deepest chasma to the tallest volcano, individual dunes inside craters and dune fields that encircle the north pole, channels carved by water and lava, and a variety of other feature, THEMIS has imaged them all. For the next several months the image of the day will focus on the Tharsis volcanoes, the various chasmata of Valles Marineris, and the major dunes fields. We hope you enjoy these images!

This prototype of a collapsible Mars lander base is part of SHIELD (Simplified High Impact Energy Landing Device), a project aimed at developing spacecraft that would intentionally crash land on the Red Planet, using an accordion-like, collapsible base that acts like the crumple zone of a car to absorb the energy of a hard impact. The design could drastically reduce the cost of landing on Mars by simplifying the harrowing entry, descent, and landing process and expanding options for possible landing sites. Developed at NASA's Jet Propulsion Laboratory in Southern California, the prototype was attached to a drop tower on Aug. 12, 2022, at JPL. https://photojournal.jpl.nasa.gov/catalog/PIA25420
