Walter (Wally) M. Schirra in Visual Docking Simulator From A.W. Vogeley, "Piloted Space-Flight Simulation at Langley Research Center," Paper presented at the American Society of Mechanical Engineers 1966 Winter Meeting, New York, NY, November 27-December 1, 1966. "This facility was [later known as the Visual-Optical Simulator. It presents to the pilot an out-the-window view of his target in correct 6 degrees of freedom motion. The scene is obtained by a television camera pick-up viewing a small-scale gimbaled model of the target. "For docking studies, the docking target picture was projected onto the surface of a 20-foot-diameter sphere and the pilot could, effectively, maneuver into contract. this facility was used in a comparison study with the Rendezvous Docking Simulator - one of the few comparison experiments in which conditions were carefully controlled and a reasonable sample of pilots used. All pilots preferred the more realistic RDS visual scene. The pilots generally liked the RDS angular motion cues although some objected to the false gravity cues that these motions introduced. Training time was shorter on the RDS, but final performance on both simulators was essentially equal. " "For station-keeping studies, since close approach is not required, the target was presented to the pilot through a virtual-image system which projects his view to infinity, providing a more realistic effect. In addition to the target, the system also projects a star and horizon background. "

CAPE CANAVERAL, Fla. – At Astrotech in Titusville, Fla., workers prepare forward fifth segment simulator of the Ares I-X for cork application. Ares I-X is the test vehicle for the Ares I, which is part of the Constellation Program to return men to the moon and beyond. Ares I is the essential core of a safe, reliable, cost-effective space transportation system that eventually will carry crewed missions back to the moon, on to Mars and out into the solar system. Ares I may also use its 25-ton payload capacity to deliver resources and supplies to the International Space Station, or to "park" payloads in orbit for retrieval by other spacecraft bound for the moon or other destinations. The Ares I-X is targeted for launch in July 2009. Photo credit: NASA/Tim Jacobs

NASA Researchers view a demonstration of the moon dust simulator in the 8- by 6-Foot Supersonic Wind Tunnel facility at the National Aeronautics and Space Administration (NASA) Lewis Research Center. The researchers were studying the effect of the lunar lander’s retrorockets on the loose dust on the lunar surface. There was some concern that the retrorockets would kick up so much dust that the crew would lose the ability to see. They also did not know how the dust’s behavior would be affected by the space atmosphere. This small vacuum tank was built for very preliminary investigations into this matter. The pipe entering the top of the tank supplied the airflow to the lander model, which was affixed to the pipe. The researchers altered the vacuum levels and speed of the airflow.

An Engineer maps out the position of rocks during VIPER testing at The NASA Glenn Research Center. A test version of the VIPER rover continues to show how well it moves through a simulated lunar surface in our SLOPE lab. This is a critical step toward ensuring the rover is ready for its 2023 mission to find water ice at the Moon’s South pole.

These photos show how teams at NASA’s Marshall Space Flight Center in Huntsville, Alabama, are using the Flat Floor Facility (Building 4619) to understand the lunar lighting environment in preparation for the Artemis III crewed lunar landing mission, slated for 2027. The Flat Floor Facility is an air-bearing floor, providing full-scale simulation capabilities for lunar surface systems by simulating zero gravity in two dimensions. Wearing low-fidelity materials, test engineers can understand how the extreme lighting of the Moon’s South Pole could affect surface operations during Artemis III. High-intensity lights are positioned at a low angle to replicate the strong shadows that are cast across the lunar South Pole by the Sun. Data and analysis from testing at NASA Marshall are improving models Artemis astronauts will use in preparation for lander and surface operations on the Moon during Artemis III. Testing in the facility is also helping cross-agency teams evaluate various tools astronauts may use. NASA Marshall manages the Human Landing System (HLS) Program.

Move crews at NASA’s Michoud Assembly Facility in New Orleans guide the Inter-Stage Simulator (ISS) to the Michoud deep water port on Monday, Sept. 19 in preparation for transportation by barge to the agency’s Stennis Space Center near Bay St. Louis, Mississippi. Once it arrives at Stennis, the simulator will be lifted into the B2 Test Stand, where it holds the Exploration Upper Stage (EUS) in place and acts as a thrust takeout. ISS protects the lower portion of the EUS from environmental elements during its Green Run tests. The term “green” refers to the new hardware, and “run” refers to operation all the components together for the first time. During tanking and launch for its future mission, the lower portion is shrouded in a flight interstage. EUS is part of the SLS Block 1B configuration. The more powerful configuration of the SLS rocket will provide in-space propulsion to send astronauts in NASA’s Orion spacecraft and 40% more cargo mass on a precise trajectory to the Moon. Through the Artemis missions, NASA will land the first woman and the first person of color on the Moon to pave the way for a sustainable presence on the Moon and future missions beyond.

Artists used paintbrushes and airbrushes to recreate the lunar surface on each of the four models comprising the LOLA simulator. Project LOLA or Lunar Orbit and Landing Approach was a simulator built at Langley to study problems related to landing on the lunar surface. It was a complex project that cost nearly $2 million dollars. James Hansen wrote: "This simulator was designed to provide a pilot with a detailed visual encounter with the lunar surface; the machine consisted primarily of a cockpit, a closed-circuit TV system, and four large murals or scale models representing portions of the lunar surface as seen from various altitudes. The pilot in the cockpit moved along a track past these murals which would accustom him to the visual cues for controlling a spacecraft in the vicinity of the moon. Unfortunately, such a simulation--although great fun and quite aesthetic--was not helpful because flight in lunar orbit posed no special problems other than the rendezvous with the LEM, which the device did not simulate. Not long after the end of Apollo, the expensive machine was dismantled." (p. 379) Ellis J. White further described LOLA in his paper "Discussion of Three Typical Langley Research Center Simulation Programs," "Model 1 is a 20-foot-diameter sphere mounted on a rotating base and is scaled 1 in. = 9 miles. Models 2,3, and 4 are approximately 15x40 feet scaled sections of model 1. Model 4 is a scaled-up section of the Crater Alphonsus and the scale is 1 in. = 200 feet. All models are in full relief except the sphere." -- Published in James R.

This image is a simulation of how NASA's Europa Clipper will understand which areas of the Jovian moon Europa are warm and active by studying the moon's thermal emissions. Scientists based this image on a model of data from NASA's Galileo mission and data from an instrument on NASA's Cassini mission that studied warm regions of Saturn's moon Enceladus where jets of water ice and organic chemicals spray out from vents in the icy surface. Europa Clipper's Europa Thermal Emission Imaging System, or E-THEMIS, will take both daytime and nighttime observations of Europa. The light pink vertical stripes simulate the warm vents seen on the surface of Enceladus, if they were viewed on Europa in the night. If Europa has warm spots like Enceladus, E-THEMIS is expected to detect such areas on Europa, even from a distance. Europa Clipper will get as close as 16 miles (25 kilometers) from the moon's surface, resulting in observations at much higher resolution. Europa Clipper's three main science objectives are to determine the thickness of the moon's icy shell and its interactions with the ocean below, to investigate its composition, and to characterize its geology. The mission's detailed exploration of Europa will help scientists better understand the astrobiological potential for habitable worlds beyond our planet. https://photojournal.jpl.nasa.gov/catalog/PIA26105

This collage of NASA Cassini spacecraft images and computer simulations shows how long, sinuous features from Enceladus can be modeled by tracing the trajectories of tiny, icy grains ejected from the moon south polar geysers.

After starting the descent, the second cart is readied on model 2 and, at the proper time, when superposition occurs, the pilot s scene is switched from model 1 to model 2. then cart 1 is moved to and readied on model 3. The procedure continues until an altitude of 150 feet is obtained. The cabin of the LM vehicle has four windows which represent a 45 degree field of view. The projection screens in front of each window represent 65 degrees which allows limited head motion before the edges of the display can be seen. The lunar scene is presented to the pilot by rear projection on the screens with four Schmidt television projectors. The attitude orientation of the vehicle is represented by changing the lunar scene through the portholes determined by the scan pattern of four orthicons. The stars are front projected onto the upper three screens with a four-axis starfield generation (starball) mounted over the cabin and there is a separate starball for the low window. -- Published in James R.

The liquid hydrogen tank that will be part of the Space Launch System rocket’s core stage is being prepared for the Artemis III mission at NASA’s Michoud Assembly Facility in New Orleans. Eventually, the tank will be connected to the engine section that will house the four RS-25 engines. The engine section is still being outfitted, so for this test crews attached an engine section aft simulator during proof testing on January 27, 2022. Once the aft simulator is attached, the LH2 tank undergoes non-destructive evaluation, which will test weld strength and ensure the tank is structurally sound. The SLS core stage is made up of five unique elements: the forward skirt, liquid oxygen tank, intertank, liquid hydrogen tank, and the engine section. The tank holds 537,000 gallons of liquid hydrogen cooled to minus 432 degrees Fahrenheit and sits between the core stage’s intertank and engine section. The liquid hydrogen hardware, along with the liquid oxygen tank, will provide propellant to the four RS-25 engines at the bottom of the core stage to produce more than two million pounds of thrust to help launch the Artemis III mission to the Moon. Together with its four RS-25 engines, the rocket’s massive 212-foot-tall core stage — the largest stage NASA has ever built — and its twin solid rocket boosters will produce 8.8 million pounds of thrust to send NASA’s Orion spacecraft, astronauts and supplies beyond Earth’s orbit to the Moon.

The liquid hydrogen tank that will be part of the Space Launch System rocket’s core stage is being prepared for the Artemis III mission at NASA’s Michoud Assembly Facility in New Orleans. Eventually, the tank will be connected to the engine section that will house the four RS-25 engines. The engine section is still being outfitted, so for this test crews attached an engine section aft simulator during proof testing on January 27, 2022. Once the aft simulator is attached, the LH2 tank undergoes non-destructive evaluation, which will test weld strength and ensure the tank is structurally sound. The SLS core stage is made up of five unique elements: the forward skirt, liquid oxygen tank, intertank, liquid hydrogen tank, and the engine section.

In a laboratory simulating conditions on Jupiter's moon Europa at NASA's Jet Propulsion Laboratory in Pasadena, California, plain white table salt (sodium chloride) turned yellow (visible in a small well at the center of this photograph). The color is significant because scientists can now deduce that the yellow color previously observed on portions of the surface of Europa is actually sodium chloride. The JPL lab experiments matched temperature, pressure and electron radiation conditions at Europa's surface. https://photojournal.jpl.nasa.gov/catalog/PIA23273

CAPE CANAVERAL, Fla. -- The upper stage simulator segments are positioned across the floor of the Vehicle Assembly Building's high bay 4 at NASA's Kennedy Space Center in Florida. Four of the segments are already stacked. The upper stage simulator will be used in the test flight identified as Ares I-X in 2009. Ares I-X is the test vehicle for the Ares I, which is part of the Constellation Program to return men to the moon and beyond. Ares I is the essential core of a safe, reliable, cost-effective space transportation system that eventually will carry crewed missions back to the moon, on to Mars and out into the solar system. Ares I may also use its 25-ton payload capacity to deliver resources and supplies to the International Space Station, or to "park" payloads in orbit for retrieval by other spacecraft bound for the moon or other destinations. The upper stage simulator comprises 11 segments, each approximately 18 feet in diameter. The simulator segments will simulate the mass and the outer mold line and will be more than 100 feet of the total vehicle height of 327 feet. Photo credit: NASA/Jack Pfaller

In a clean room at NASA's Jet Propulsion Laboratory in Southern California in March 2024, engineers and technicians prepare the agency's Farside Seismic Suite (FSS) for testing. The cube-shaped payload contains two instruments that will gather NASA's first seismic data from the Moon in nearly 50 years and take the first-ever seismic measurements from the Moon's far side. FSS will operate continuously for at least 4½ months, working through the long, cold lunar nights. Here, engineers move FSS onto a fixture that will allow them to tilt the payload, simulating the pull of lunar gravity in the direction at which one of the instrument's two seismometers is sensitive to motion. (The Moon's gravity is about one-sixth of Earth's.) Called an ambient tilt test, this activity allows engineers to check the seismometers' performance. The two seismometers are packaged together with a large battery, a computer, and electronics inside a cube structure that's surrounded by several layers of insulation and suspended within an outer protective cube, which is in turn covered with a shiny insulating blanket. The suite's single solar panel can be seen right of center. Surrounding the instrument are (from left): Nik Schwarz, Vik Singh, Joanna Farias, and Bert Turney. https://photojournal.jpl.nasa.gov/catalog/PIA26298

These photos and videos show how NASA certified a new lander flight training course using helicopters in the mountains of northern Colorado. NASA is partnering with the Colorado Army National Guard at its High-Altitude Army National Guard Aviation Training Site near Gypsum, Colorado, to develop the foundational flight training course that will help astronauts practice flight and landing procedures for the Moon. The certification marks an important milestone in crew training for Artemis missions to the Moon, when astronauts will use a commercial human landing system to land on the lunar surface. During the two-week certification run in late August 2025, NASA astronauts Matthew Dominick and Mark Vande Hei participated in flight and landing training to help certify the course. The pair, along with trained instructor pilots with the Army National Guard, took turns flying a helicopter and navigating to landing zones. Artemis flight crew trainers, mission control leads, and lunar lander operational experts from NASA Johnson joined them on each helicopter flight to assess the instruction, training environment, and technical applications for crewed lunar missions.

Researchers at NASA’s Ames Research Center in California’s Silicon Valley complete a successful vibration test of the Neutron Spectrometer System or NSS, designed to sniff out water below the surface of the Moon, successfully sailed through a “shake” test to simulate the turbulent conditions of launch. . This is one of the final tests needed to prepare the instrument for a flight to the Moon aboard Astrobotic Technology’s Peregrine lander, as part of the agency’s Commercial Lunar Payload Services program. The vibration test simulates the forces the instrument will be subjected to during launch when the lander blasts off aboard a United Launch Alliance Vulcan Centaur rocket. The NSS will fly on the Volatiles Investigating Polar Exploration Rover, or VIPER.
