Josh Litofsky leads a Gateway lunar dust adhesion testing campaign at NASA’s Johnson Space Center in Houston. His team studies how lunar dust interacts with materials chosen for Gateway's construction. Here, Litofsky scoops lunar stimulant into a sample holder. Litofksy’s work seeks to validate the Gateway On-orbit Lunar Dust Modeling and Analysis Program (GOLDMAP), developed by Ronald Lee, also of Johnson Space Center. By considering factors such as the design and configuration of the space station, the materials used, and the unique conditions in lunar orbit, GOLDMAP helps predict how dust may move and settle on Gateway’s external surfaces.

This photograph was taken during the testing of the Lunar Roving Vehicle (LRV) at the Johnson Space Center. Developed by the MSFC, the LRV was the lightweight electric car designed to increase the range of mobility and productivity of astronauts on the lunar surface. It was used on the last three Apollo missions; Apollo 15, Apollo 16, and Apollo 17.

S75-23543 (April 1972) --- This Apollo 16 lunar sample (moon rock) was collected by astronaut John W. Young, commander of the mission, about 15 meters southwest of the landing site. This rock weighs 128 grams when returned to Earth. The sample is a polymict breccia. This rock, like all lunar highland breccias, is very old, about 3,900,000,000 years older than 99.99% of all Earth surface rocks, according to scientists. Scientific research is being conducted on the balance of this sample at NASA's Johnson Space Center and at other research centers in the United States and certain foreign nations under a continuing program of investigation involving lunar samples collected during the Apollo program.

Rob Morehead, lead propulsion engineer for Intuitive Machines in Houston, delivers the monthly Tech Talk on Oct. 24 at NASA’s Marshall Space Flight Center. Morehead presented Intuitive Machines’ Nova-C lunar lander, which will deliver payloads to the surface of the Moon for government and commercial customers, including NASA. Intuitive Machines was selected by the agency as one of the companies for NASA’s Commercial Lunar Payload Service program. Nova-C currently has five NASA payloads and two commercial payloads manifested for its first flight, slated to launch in 2021. It will reach the Moon six days after launch and operate on the lunar surface for 12 days. Morehead worked at NASA’s Johnson Space Center for 20 years before joining Intuitive Machines.

Dr. Gary Latham of the Lamont-Doherty Geological Observatory is the principal investigator for the Passive Seismic Experiment, a component of the Apollo Lunar Surface Experiments Package.

Technicians prepare the Mass Spectrometer Observing Lunar Operations (MSolo) for NASA’s Volatile Investigating Polar Exploration Rover (VIPER) mission for packing inside a laboratory in the Space Station Processing Facility at NASA’s Kennedy Space Center in Florida on Feb. 21, 2023. MSolo will be shipped to Johnson Space Center in Houston for integration into VIPER. MSolo is a commercial off-the-shelf mass spectrometer modified to work in space and it will help analyze the chemical makeup of landing sites on the Moon, as well as study water on the lunar surface. MSolo will be part of NASA’s first Commercial Lunar Payload Delivery Service (CLPS) mission where under the Artemis program, commercial deliveries will be used to perform science experiments, test technologies, and demonstrate capabilities to help NASA explore the Moon and prepare for human missions. VIPER is scheduled to be delivered to the Moon’s South Pole in late 2024 by Astrobotic’s Griffin lander as part of the CLPS initiative.

A boot that's part of a NASA lunar surface spacesuit prototype is readied for testing inside a thermal vacuum chamber called CITADEL at the agency's Jet Propulsion Laboratory in Southern California on Nov. 8, 2024. The thick aluminum plate at right stands in for the frigid surface of the lunar South Pole, where Artemis III astronauts will confront conditions more extreme than any previously experienced by humans. Built to prepare potential future robotic spacecraft for the frosty, low-pressure conditions on ocean worlds like Jupiter's frozen moon Europa, CITADEL (Cryogenic Ice Testing, Acquisition Development, and Excavation Laboratory) has also proven key to evaluating how astronaut gloves and boots hold up in extraordinary cold. It can reach temperatures as low as low as minus 370 degrees Fahrenheit (minus 223 degrees Celsius), approximating conditions in permanently shadowed regions that astronauts will explore. Figure A, showing the outer boot sole, was taken from inside CITADEL on Nov. 13, 2024. The boot is positioned in a load lock, one of four small drawer-like chambers through which test materials are inserted into the larger chamber. Initiated by the Extravehicular Activity and Human Surface Mobility Program at NASA's Johnson Space Center, the boot testing took place from October 2024 to January 2025. The boot is part of a NASA spacesuit called the Exploration Extravehicular Mobility Unit, or xEMU. Results haven't yet been fully analyzed. In addition to spotting vulnerabilities with existing suits, the experiments are intended to help NASA develop this unique test capability and prepare criteria for standardized, repeatable, and inexpensive test methods for the next-generation lunar suit being built by Axiom Space. https://photojournal.jpl.nasa.gov/catalog/PIA26592

Virtual Intelligent Planetary Exploration Rover, VIPER Mobility Platform Testing An engineering model of the Volatiles Investigating Polar Exploration Rover, or VIPER, is tested in the Simulated Lunar Operations Laboratory at NASA’s Glenn Research Center in Cleveland, Ohio. About the size of a golf cart, VIPER is a mobile robot that will roam around the Moon’s South Pole looking for water ice in the region and for the first time ever, actually sample the water ice at the same pole where the first woman and next man will land in 2024 under the Artemis program. The large, adjustable soil bin contains lunar simulant and allows engineers to mimic the Moon’s terrain. Engineers from NASA’s Johnson Space Center in Houston, where the rover was designed and built, joined the Glenn team to complete the tests. Test data will be used to evaluate the traction of the vehicle and wheels, determine the power requirements for a variety of maneuvers and compare methods of traversing steep slopes. Respirators are worn by researchers to protect against the airborne silica that is present during testing. VIPER is a collaboration within and beyond the agency. NASA's Ames Research Center in Silicon Valley is managing the project, leading the mission’s science, systems engineering, real-time rover surface operations and software. The rover’s instruments are provided by Ames, NASA’s Kennedy Space Center in Florida and commercial partner, Honeybee Robotics in California. The spacecraft, lander and launch vehicle that will deliver VIPER to the surface of the Moon will be provided through NASA’s Commercial Lunar Payload Services program, delivering science and technology payloads to and near the Moon.
