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. For more information, contact NASA Marshall’s Office of Communications at 256-544-0034.

CAPE CANAVERAL, Fla. – At NASA’s Kennedy Space Center in Florida, modifications continue to Firing Room 3 in the Launch Control Center, or LCC. Wiring and conduits below the floor have been upgraded. The legacy flooring leading to and inside a viewing room has been removed and the area is being prepared for new flooring to be installed. Firing Rooms inside the LCC are being upgraded by the Ground System Development and Operations Program at Kennedy to support the processing and launch of multiple types of rockets and spacecraft, whether they are government or commercial models.

The floor of this crater in Arabia Terra has been filled with material that is now being eroded away

STS078-432-009 (20 June-7 July 1996) --- Among the inflight maintenance (IFM) chores that were handled by the crew members during their almost 17 days in space aboard the space shuttle Columbia was one that involved going into the bay beneath the floor of the Life and Microgravity Spacelab (LMS-1) Science Module. Astronaut Terence T. (Tom) Henricks, mission commander, shines a tiny flashlight onto some cables related to LMS-1 supported computer systems. As in the case of the other IFM chores, Henricks' efforts were successful. He was joined by four other NASA astronauts and two international payload specialists for the space shuttle duration record-setting mission.

Today's VIS image shows a portion of the floor of an unnamed crater in Arabia Terra. Like several other craters on Mars, including the nearby Henry Crater, this crater contains a large mound of material that filled a large part of the crater floor. This mound has been subsequently eroded by the wind. These materials were brought into the crater sometime after the impact that formed the crater.

Today's VIS image shows part of an unnamed crater located in Noachis Terra. Unlike most Martian craters, this one has a very rugged floor. Most craters have flat floors, having been filled with materials such as sand blown into the crater, layered deposits from short term lakes, and volcanic materials from nearby flows. The morphology of the crater floor indicates that this is a relatively young crater, with the original floor created during the impact event.

This VIS image crosses an unnamed crater in Terra Sabaea. The entire crater floor is covered by materials of unknown origin. Those materials are be eroded and appear to be forming chaos. The channel feature may be related to fluid activity, where the underlying material is losing water and the surface is collapsing – rather than the flow of a river over the surface.

West of NASA Curiosity landing site, this image from NASA Mars Reconnaissance Orbiter spacecraft along the northwestern floor of Gale Crater is between Aeolis Mons informally called Mt. Sharp and the crater rim.

The impact crater observed in this NASA Mars Odyssey image taken in Terra Cimmeria suggests sediments have filled the crater due to the flat and smooth nature of the floor compared to rougher surfaces at higher elevations.

This image from NASA Mars Reconnaissance Rover shows a degraded impact crater in the southern highlands. Part of the crater rim is visible at the top and bottom of the image, with the boulder-covered crater floor in the center.

The central peak and fractured floor of Compton crater as imaged by the LROC Narrow Angle Camera onboard NASA Lunar Reconnaissance Orbiter at dusk, image width is ~1720 meters.

Taken by one of the Mars Student Imaging Project MSIP teams, these are the unusual floor deposits in Spallanzani Crater. The wind may have affected the surface of the layered deposit. Small dunes have formed near the southern margin

This crater on Mars, observed by NASA Mars Reconnaissance Orbiter, was named after Dr. Gerald A. Soffen February 7, 1926 - November 22, 2000, and this image covers a small portion of the crater floor. http://photojournal.jpl.nasa.gov/catalog/PIA14453

This NASA Mars Odyssey image shows a remarkable array of dunes on the floor of a large impact crater named Baldet. Many of the dunes in this region are isolated features with large, sand-free interdune surfaces between the individual dunes.

This image, from NASA Mariner 10 spacecraft which launched in 1974, shows several scarps, which appear to be confined to crater floors. The scarp in the crater at the upper left of the image has been diverted by the central peaks.

This image shows some bright layered deposits exposed within a linear trough along the floor of the Ladon Basin as seen by NASA Mars Reconnaissance Orbiter.

This image shows the floor of Suzhi Crater, an approximately 25-kilometer diameter impact crater located northeast of Hellas Planitia. The crater floor is mostly covered by dark-toned deposits; however some patches of the underlying light-toned bedrock are now exposed, like in this Context Camera image. This enhanced-color infrared image shows a close up of the exposed bedrock on the floor of the crater. Here we can see the lighter-toned bedrock partially covered up by darker-toned bedrock and a few wind-blown bedforms. The lighter-toned bedrock appears to lie over yet another type of bedrock in our image, which appears to be yellowish and heavily fractured. What complex tale of Martian geologic and climate history might these rocks tell us if we were able to sample them in person? Perhaps, one day we'll know.
