This mosaic image shows an extreme close-up of round, blueberry-shaped formations in the martian soil near a part of the rock outcrop at Meridiani Planum called Stone Mountain. Scientists are studying these curious formations for clues about the area's past environmental conditions. The image, one of the highest resolution images ever taken by the microscopic imager, an instrument located on the Mars Exploration Rover Opportunity's instrument deployment device or "arm." http://photojournal.jpl.nasa.gov/catalog/PIA05273

In this photograph, a tethered Axel robot — part of the four-wheeled DuAxel rover — navigates a steep slope during a field test in the Mojave Desert. The tether, which connects to the rover's other half, serves as a climbing rope of sorts while also providing power and a means of communication. This flexibility was built with crater walls, pits, scarps, vents, and other extreme terrain in mind. That's because on Earth, some of the best locations to study geology can be found in rocky outcrops and cliff faces, where many layers of the past are neatly exposed. They're hard enough to reach here, let alone on the Moon, Mars, and other celestial bodies. The DuAxel project is a technology demonstration being developed by roboticists at NASA's Jet Propulsion Laboratory in Southern California to see how this unconventional rover might fill a niche in planetary exploration. https://photojournal.jpl.nasa.gov/catalog/PIA24110

This microscopic imager mosaic of the rock called "Diamond Jenness" was snapped on sol 177 before NASA's Mars Exploration Rover Opportunity ground into the surface with its rock abrasion tool, or "Rat." Opportunity has bored nearly a dozen holes into the inner walls of "Endurance Crater." On sols 177 and 178 (July 23 and July 24, 2004), the rover worked double-duty on Diamond Jenness. Surface debris and the bumpy shape of the rock resulted in a shallow and irregular hole, only about 2 millimeters (0.08 inch) deep. The final depth was not enough to remove all the bumps and leave a neat hole with a smooth floor. This extremely shallow depression was then examined by the rover's alpha particle X-ray spectrometer. On Sol 178, Opportunity's "robotic rodent" dined on Diamond Jenness once again, grinding almost an additional 5 millimeters (about 0.2 inch). The rover then applied its Moessbauer spectrometer to the deepened hole. This double dose of Diamond Jenness enabled the science team to examine the rock at varying layers. Results from those grindings are currently being analyzed. The image mosaic is about 6 centimeters (2.4 inches) across. http://photojournal.jpl.nasa.gov/catalog/PIA06748

An engineer prepares a small rover – part of NASA's CADRE (Cooperative Autonomous Distributed Robotic Exploration) technology demonstration that's headed to the Moon – for testing in a thermal vacuum chamber at the agency's Jet Propulsion Laboratory in Southern California in October 2023. Slated to arrive at the Moon in 2024 as part of NASA's CLPS (Commercial Lunar Payload Services) initiative, CADRE is designed to demonstrate that multiple robots can cooperate and explore together autonomously – without direct input from human mission controllers. A trio of the miniature solar-powered rovers, each about the size of a carry-on suitcase, will explore the Moon as a team, communicating via radio with each other and a base station aboard a lunar lander. By taking simultaneous measurements from multiple locations, CADRE will also demonstrate how multirobot missions can record data impossible for a single robot to achieve – a tantalizing prospect for future missions. The rover being tested is the first flight model to be completed. Thermal vacuum testing simulates the harsh environment the rovers will face on the journey to the Moon and on the lunar surface: All the air is pumped out of the chamber and the temperature is cycled to high and low extremes. https://photojournal.jpl.nasa.gov/catalog/PIA25669

AS15-85-11437 (31 July 1971) --- Astronaut David R. Scott, commander, with tongs and gnomon in hand, studies a boulder on the slope of Hadley Delta during the Apollo 15 lunar landing mission's first extravehicular activity (EVA). The Lunar Roving Vehicle (LRV), "Rover", is in the right foreground. The view is looking slightly south of west. "Bennett Hill" is at extreme right. Astronaut James B. Irwin, lunar module pilot, took this photograph. While astronauts Scott and Irwin descended together in the Lunar Module (LM) "Falcon" to explore the Hadley-Apennine area of the moon, astronaut Alfred M. Worden, command module pilot, remained with the Command and Service Modules (CSM) in lunar orbit.

Two full-scale development model rovers that are part of NASA's CADRE (Cooperative Autonomous Distributed Robotic Exploration) technology demonstration drive in the Mars Yard at the agency's Jet Propulsion Laboratory in Southern California in August 2023. The project is designed to show that a group of robotic spacecraft can work together as a team to accomplish tasks and record data autonomously – without explicit commands from mission controllers on Earth. The rovers being tested here are similar in size and appearance to the flight models – still being built at the time of this image – that will travel to the Moon. Equipped with flight software and autonomy capabilities, these development models were used for drive tests outside the clean room. In this image, one rover is fitted with a stand-in for solar panels, while the other rover is not. A series of Mars Yard tests with the development models confirmed CADRE hardware and software can work together to accomplish key goals for the project. The rovers drove together in formation. Faced with unexpected obstacles in the way, they adjusted their plans as a group by sharing updated maps and replanning coordinated paths. And when one rover was low on battery charge, the whole team paused so they could later continue together. Several drives were performed at night under large flood lamps so the rovers could experience extreme shadows and lighting that approximate what they'll encounter during the lunar daytime. https://photojournal.jpl.nasa.gov/catalog/PIA26168

Engineers and technicians at NASA’s Kennedy Space Center in Florida prepare to install the radiator for the Mass Spectrometer Observing Lunar Operations (MSolo) instrument inside the Space Station Processing Facility on Sept. 25, 2020. MSolo will help analyze the chemical makeup of landing sites on the Moon, as well as study water on the lunar surface. The radiator will help keep the instrument’s temperature stable in the extreme heat and cold it will encounter. MSolo instruments are scheduled to launch on multiple robotic missions as part of NASA’s Commercial Lunar Payload Services (CLPS), with the first of these missions exploring Lacus Mortis, a large crater on the near side of the Moon, beginning in 2021. MSolo also will be one of three instruments on the agency’s water-hunting Volatiles Investigating Polar Exploration Rover, VIPER, scheduled to launch to the Moon’s South Pole in late 2023.

The descent stage holding NASA's Perseverance rover can be seen falling through the Martian atmosphere, its parachute trailing behind, in this image taken on Feb. 18, 2021, by the High Resolution Imaging Experiment (HiRISE) camera aboard the Mars Reconnaissance Orbiter. The ancient river delta, which is the target of the Perseverance mission, can be seen entering Jezero Crater from the left. HiRISE was approximately 435 miles (700 kilometers) from Perseverance and traveling at about 6750 mile per hour (3 kilometers per second) at the time the image was taken. The extreme distance and high speeds of the two spacecraft were challenging conditions that required precise timing and for Mars Reconnaissance Orbiter to both pitch upward and roll hard to the left so that Perseverance was viewable by HiRISE at just the right moment. https://photojournal.jpl.nasa.gov/catalog/PIA24270

An electrical cable can be seen snaking its way along insulation material in this image of the interior of the Mars 2020 spacecraft at it cruises through interplanetary space to the Red Planet. The cable and insulation are tied to the inside of the spacecraft's heat shield, which will protect the spacecraft from the extreme temperatures generated by friction as it enters the Martian atmosphere on Feb 18, 2021. The light source is the Sun, which likely entered through a vent hole in the Multi-Mission Radioisotope Thermoelectric Generator (MMRTG) door. The picture was assembled from three images taken at different times by the Perseverance rover's rear left Hazcam during a systems check on Oct. 19, 2020. The colored pixels seen in the image are due to digital noise from the camera. https://photojournal.jpl.nasa.gov/catalog/PIA24233

This picture of the rim of Eos Chasma in Valles Marineris shows active erosion of the Martian surface. Layered bedrock is exposed in a steep cliff on a spur of the canyon rim. Dark layers in this cliff are made up of large boulders up to 4 meters in diameter. The boulders are lined up along specific horizons, presumably individual lava flows, and are perched to descend down into the canyon upon the slightest disturbance. How long will the boulders remain poised to fall, and what will push them over the edge? Just as on Earth, the main factors that contribute to dry mass wasting erosion on Mars are frost heaving and thermal expansion and contraction due to changes in temperature. The temperature changes on Mars are extreme compared to Earth, because of the lack of humidity in the Martian atmosphere and the eccentricity of the Martian orbit. Each daily temperature cycle and each seasonal change from summer to winter produces a cycle of expansion and contraction that pushes the boulders gradually closer to the brink. Inevitably, the boulders fall from their precarious positions and plunge into the canyons below. Most simply slide down slope and collect just below the source layers. A few are launched along downward trajectories, travelling long distances before they settle on the slopes below. These trundling boulders left behind conspicuous tracks, up to a kilometer long. The tracks resemble dashed lines or perforations, indicating that the boulders bounced as they trundled down the slopes. The visibility of the boulder tracks suggests that this process may have taken place recently. The active Martian winds quickly erased the tracks of the rover Opportunity, for example. However, the gouges produced by trundling boulders probably go much deeper than the shallow compression of soil by the wheels of a relatively lightweight rover. The boulder tracks might persist for a much longer time span than the rover tracks for this reason. Nevertheless, the tracks of the boulders suggest that erosion of the rim of Eos Chasma is a process that continues today. http://photojournal.jpl.nasa.gov/catalog/PIA21203

This illustration depicts the exterior of a sample tube being carried aboard the Mars 2020 Perseverance rover. About the size and shape of a standard lab test tube, the 43 sample tubes headed to Mars must be lightweight, hardy enough to survive the demands of the round trip, and so clean that future scientists will be confident that what they are analyzing is 100% Mars, without Earthly contaminants. Exterior Ball Lock: Placed on opposite sides of the tube, the two ball locks help secure the sample tube as it progresses through the many stages of sample collection and storage. Serial Number: Helps with identification of the tubes and their contents. Titanium Nitride Coating: Gold in color, this extremely hard ceramic coating is used as a specialized surface treatment that resists contamination. Alumina Coating: The reflective coating provides thermal protection and acts as a sponge to prevent potential contaminants from getting inside the sample tube. Bare Titanium: The portion of tube near the open end contains no coating to eliminate the possibility that the coating could delaminate from this portion of the tube during the insertion of a hermetic seal. Bearing Race: An asymmetrical flange at the open end of the tube, it assists in the process of shearing (breaking) off samples at the completion of the coring portion of sample collection. https://photojournal.jpl.nasa.gov/catalog/PIA24306

An engineer in the clean room at Lockheed Martin Space in Littleton, Colorado, affixes a dime-size chip onto the lander deck of NASA's InSight spacecraft. This second microchip, contains 1.6 million names submitted by the public to ride along with InSight to Mars. The chip was installed on Jan. 23, 2018. This joins another microchip that was previously installed that included 800,000 names for a grand total of 2.4 million names going to Mars as early as May 5, 2018. Engineers at NASA's Jet Propulsion Laboratory, Pasadena, California, put the names onto this tiny 0.3 square inches (8 millimeter-square) silicon wafer microchip using an electron beam to write extremely tiny letters with lines smaller than one one-thousandth the width of a human hair. The dime-size chip is affixed to the InSight lander deck and will remain on Mars forever. Normally used to make high-precision nanometer-scale devices, this technique was also used to write millions of names that were transported on NASA Mars rovers and Orion's first test flight. InSight is the first Mars mission dedicated to study the deep interior of Mars. Its findings will advance understanding of the early history of all rocky planets, including Earth. https://photojournal.jpl.nasa.gov/catalog/PIA22236

This image from NASA Mars Reconnaissance Orbiter shows a region of Acidalia Planitia which is covered by dense fields of boulders up to several meters high. In "The Martian" by Andy Weir (watch for the movie in late 2015), stranded astronaut Mark Watney spends most of his time at the "Ares 3" site in southern Acidalia Planitia. The book describes Acidalia as flat and easy to drive over; he even drives to the Pathfinder landing site and back. This region of Mars is actually far more diverse, interesting, and hazardous to drive over than depicted in the novel. These two images (this observation and ESP_019783_2115) are close to the Ares 3 landing site as shown in a map at the front of the novel, and shows many mounds, perhaps ancient volcanoes resulting from lava-water interaction or eruption of muddy sediments. Much of Acidalia Planitia is covered by dense fields of boulders up to several meters high that would be difficult to drive around. There are also fissures associated with giant polygons, with steep rocky slopes that would be impassable. There are elongated fields of dense secondary craters where the surface is extremely rough at scales near the size of the rover. When our hero travels into Arabia Terra it is described as much rockier than Acidalia, but the the opposite is generally true: much of Arabia is dust mantled and smooth at the scale of a rover. People commonly assume that smooth at large scales (kilometers) means smooth at small scales ( meters to tens of meters). Often on Mars, the exact opposite is seen: large flat low areas are more wind-scoured, removing fine materials and leaving rocks and eroded bedrock. http://photojournal.jpl.nasa.gov/catalog/PIA19306

These photos show how technicians at NASA’s Marshall Space Flight Center in Huntsville, Alabama, have applied the thermal protection system material to the launch vehicle stage adapter (LVSA) of NASA’s SLS (Space Launch System) rocket for Artemis III, which will land astronauts on the Moon to advance long-term lunar exploration and scientific discovery and inspire the Artemis Generation. The LVSA is a cone-shaped element that connects the mega rocket’s core stage to its interim cryogenic propulsion stage (ICPS), partially enclosing it and protecting its avionics and electrical systems from the extreme pressures, sounds, and temperatures during launch and flight. Teams at Marshall began applying the thermal protection system material in the spring of 2023. Unlike other parts of the SLS rocket, the thermal protection system material for the LVSA is applied entirely by hand using a spray gun. During application, the technicians use a thin measuring rod to gauge the proper thickness. Once the thermal protection system has cured, certain areas are sanded down to meet parameters. The entire process takes several months. The LVSA is fully manufactured at Marshall by NASA, lead contractor Teledyne Brown Engineering, and the Jacobs Space Group’s ESSCA contract. The LVSA for Artemis III is the last of its kind as future SLS rockets will transition to its next, more powerful Block 1B configuration beginning with Artemis IV. NASA is working to land the first woman and first person of color on the Moon under Artemis. SLS is part of NASA’s backbone for deep space exploration, along with the Orion spacecraft, advanced spacesuits and rovers, the Gateway in orbit around the Moon, and commercial human landing systems. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single mission.

Unlike other parts of the SLS rocket, the thermal protection system material for the LVSA is applied entirely by hand using a spray gun. During application, the technicians use a thin measuring rod to gauge the proper thickness. Once the thermal protection system has cured, certain areas are sanded down to meet parameters. The entire process takes several months. The LVSA is fully manufactured at Marshall by NASA, lead contractor Teledyne Brown Engineering, and the Jacobs Space Group’s ESSCA contract. The LVSA for Artemis III is the last of its kind as future SLS rockets will transition to its next, more powerful Block 1B configuration beginning with Artemis IV. NASA is working to land the first woman and first person of color on the Moon under Artemis. SLS is part of NASA’s backbone for deep space exploration, along with the Orion spacecraft, advanced spacesuits and rovers, the Gateway in orbit around the Moon, and commercial human landing systems. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single mission.

These photos show how technicians at NASA’s Marshall Space Flight Center in Huntsville, Alabama, have applied the thermal protection system material to the launch vehicle stage adapter (LVSA) of NASA’s SLS (Space Launch System) rocket for Artemis III, which will land astronauts on the Moon to advance long-term lunar exploration and scientific discovery and inspire the Artemis Generation.
