S69-60354 (29 Nov. 1969) --- A scientist's gloved hand holds one of the numerous rock samples brought back to Earth from the Apollo 12 lunar landing mission. The rocks are under thorough examination in the Manned Spacecraft Center's (MSC) Lunar Receiving Laboratory (LRL). This sample is a highly shattered basaltic rock with a thin black-glass coating on five of its six sides. Glass fills fractures and cements the rock together. The rock appears to have been shattered and thrown out by a meteorite impact explosion and coated with molten rock material before the rock fell to the surface.

CAPE CANAVERAL, Fla. – Samples of Earth rocks and real meteorites are featured in an interactive display at the new Great Balls of Fire exhibit at NASA’s Kennedy Space Center Visitor Complex in Florida. The grand opening featured remarks by former NASA astronaut Tom Jones, and Therrin Protze, chief operating officer at Delaware North Parks and Resorts at the visitor complex. Great Balls of Fire shares the story of the origins of our solar system, asteroids and comets and their possible impacts and risks. The 1,500-square-foot exhibit, located in the East Gallery of the IMAX theatre at the visitor complex, features several interactive displays, real meteorites and replica asteroid models. The exhibit is a production of The Space Science Institute's National Center for Interactive Learning. It is a traveling exhibition that also receives funding from NASA and the National Science Foundation. Photo credit: NASA/Daniel Casper

The calibration target for SHERLOC (Scanning Habitable Environments with Raman & Luminescence for Organics & Chemicals) an instrument on the end of the Perseverance Mars rover's 7-foot-long (3-meter-long) robotic arm, includes a geocaching target, spacesuit materials, and a slice of a Martian meteorite. Scientists rely on calibration targets to fine-tune instrument settings using materials with known properties. The bottom row of this target features spacesuit materials that scientists will observe to see how they react over time to the irradiated Martian atmosphere. The first sample at left is polycarbonate for use in a helmet visor; inscribed with the address of the fictional detective Sherlock Holmes, it doubles as a geochache for the public. Other materials in the bottom row, from left: Vectran; Ortho-Fabric; Teflon; coated Teflon. Top row, from left: aluminum gallium nitride on sapphire; a quartz diffuser; a slice of Martian meteorite; a maze for testing laser intensity; a separate aluminum gallium nitride on sapphire with different properties. https://photojournal.jpl.nasa.gov/catalog/PIA24261

This HiRISE image shows a flat plain with various low, lumpy mounds. Some of them have distinct colors and tones unlike the surrounding plains, suggesting that they are made up of a different type of material. While the origin of these mounds is not certain, one idea that seems to fit best is that they are deposits left after eruptions of wet sediments onto the surface. This can happen when thick deposits of wet sand and mud are shaken, say from a meteorite impact, and the ground briefly loses its strength, allowing dirty water to be expelled from the deposit. On Earth, this process of "liquefaction" can happen during earthquakes. If this hypothesis is correct, it means that these mounds provide samples of a potentially habitable environment that we would otherwise need massive drills to reach. https://photojournal.jpl.nasa.gov/catalog/PIA25087

This image from NASA's Mars Reconnaissance Orbiter shows one of millions of small (10s of meters in diameter) craters and their ejecta material that dot the Elysium Planitia region of Mars. The small craters were likely formed when high-speed blocks of rock were thrown out by a much larger impact (about 10-kilometers in diameter) and fell back to the ground. Some of these blocks may actually escape Mars, which is how we get samples in the form of meteorites that fall to Earth. Other ejected blocks have insufficient velocity, or the wrong trajectory, to escape the Red Planet. As such, when one of these high-speed blocks impacts the surface, it makes what is called a "secondary" crater. These secondaries can form dense "chains" or "rays," which are radial to the crater that formed them. https://photojournal.jpl.nasa.gov/catalog/PIA21769

S73-15171 (4 Jan. 1973) --- These orange glass spheres and fragments are the finest particles ever brought back from the moon. Ranging in size from 20 to 45 microns (about 1/1000 of an inch) the particles are magnified 160 times in this photomicrograph made in the Lunar Receiving Laboratory at the Manned Spacecraft Center. The orange soil was brought back from the Taurus-Littrow landing site by the Apollo 17 crewmen. Scientist-astronaut Harrison H. "Jack" Schmitt discovered the orange soil at Shorty Crater during the second Apollo 17 extravehicular activity (EVA). This lunar material is being studied and analyzed by scientists in the LRL. The orange particles in this photomicrograph, which are intermixed with black and black-speckled grains, are about the same size as the particles that compose silt on Earth. Chemical analysis of the orange soil material has shown the sample to be similar to some of the samples brought back from the Apollo 11 (Sea of Tranquility) site several hundred miles to the southwest. Like those samples, it is rich in titanium (8%) and iron oxide (22%). But unlike the Apollo 11 samples, the orange soil is unexplainably rich in zinc ? an anomaly that has scientists in a quandary. This Apollo 17 sample is not high in volatile elements, nor do the minerals contain substantial amounts of water. These would have provided strong evidence of volcanic activity. On the other hand, the lack of agglutinates (rocks made up of a variety of minerals cemented together) indicates that the orange glass is probably not the product of meteorite impact -- strengthening the argument that the glass was produced by volcanic activity.

In this Apollo 17 onboard photo, Lunar Module pilot Harrison H. Schmitt collects rock samples from a huge boulder near the Valley of Tourus-Littrow on the lunar surface. The seventh and last manned lunar landing and return to Earth mission, the Apollo 17, carrying a crew of three astronauts: Schmitt; Mission Commander Eugene A. Cernan; and Command Module pilot Ronald E. Evans, lifted off on December 7, 1972 from the Kennedy Space Flight Center (KSC). Scientific objectives of the Apollo 17 mission included geological surveying and sampling of materials and surface features in a preselected area of the Taurus-Littrow region, deploying and activating surface experiments, and conducting in-flight experiments and photographic tasks during lunar orbit and transearth coast (TEC). These objectives included: Deployed experiments such as the Apollo lunar surface experiment package (ALSEP) with a Heat Flow experiment, Lunar seismic profiling (LSP), Lunar surface gravimeter (LSG), Lunar atmospheric composition experiment (LACE) and Lunar ejecta and meteorites (LEAM). The mission also included Lunar Sampling and Lunar orbital experiments. Biomedical experiments included the Biostack II Experiment and the BIOCORE experiment. The mission marked the longest Apollo mission, 504 hours, and the longest lunar surface stay time, 75 hours, which allowed the astronauts to conduct an extensive geological investigation. They collected 257 pounds (117 kilograms) of lunar samples with the use of the Marshall Space Flight Center designed Lunar Roving Vehicle (LRV). The mission ended on December 19, 1972

Different kinds of carbon-based molecules called organic compounds were viewed within a rock target called "Garde" by SHERLOC, one of the instruments on the end of the robotic arm aboard NASA's Perseverance Mars rover. The rover used its drill to abrade, or grind away, a patch of rock so that SHERLOC (Scanning Habitable Environments with Raman & Luminescence for Organics & Chemicals) could analyze its interior. This data was taken on Sept. 18, 2021, the 207th Martian day, or sol, of the mission. Nonbiological, geological processes can form organics. The organics found in PIXL's data and their association with the rocks that they're embedded within bear a striking resemblance to nonbiological organics within Martian meteorites, suggesting that these organics were formed by geological processes. Therefore, these organics findings are not biosignatures (compounds that indicate the presence of a biological process). SHERLOC made the first detection of organics on the Martian surface since the Curiosity rover. It is also the first detection of organics on the Martian surface made through ultraviolet fluorescence spectroscopy (whereas the Curiosity rover utilized a different methodology known as mass spectrometry), and it is the first discovery of the spatial distribution of organics on the Martian surface. The organics were found to be simple aromatics present at low concentrations, which is similar to what was found by the Curiosity rover and within Martian meteorites. A key objective for Perseverance's mission on Mars is astrobiology, including the search for signs of ancient microbial life. The rover will characterize the planet's geology and past climate, pave the way for human exploration of the Red Planet, and be the first mission to collect and cache Martian rock and regolith (broken rock and dust). Subsequent NASA missions, in cooperation with ESA (European Space Agency), would send spacecraft to Mars to collect these sealed samples from the surface and return them to Earth for in-depth analysis. The Mars 2020 Perseverance mission is part of NASA's Moon to Mars exploration approach, which includes Artemis missions to the Moon that will help prepare for human exploration of the Red Planet. https://photojournal.jpl.nasa.gov/catalog/PIA25042

The annotation shows where spacesuit materials can be found attached to a calibration target for SHERLOC (Scanning Habitable Environments with Raman & Luminescence for Organics and Chemicals), one of the rover's instruments. At right is a close-up of the calibration target. Scientists rely on calibration targets to fine-tune instrument settings using materials with known properties. In the case of SHERLOC's calibration target, they are also studying how the five swatches of spacesuit materials arranged along the bottom row degrade in the Martian environment. Those materials, from left to right: a piece of polycarbonate visor used in spacesuit helmets; Vectran, a cut-resistant material used for the palms of astronaut gloves; a commonly used spacesuit material called Ortho-Fabric; and two kinds of Teflon, which has dust-repelling nonstick properties. Top row, left to right: two gallium nitride targets that glow different colors when illuminated with SHERLOC's laser; a slice of Martian meteorite named Sayh al Uhaymir 008 (SaH 008); a maze designed to focus SHERLOC's camera; and a diffuse transmission target that measures how SHERLOC's laser scatters light.
