The concrete foundation placed Dec. 18 (foreground) for Stennis Space Center's future A-3 Test Stand has almost completely cured by early January, according to Bo Clarke, NASA's contracting officer technical representative for the foundation contract. By late December, construction on foundations for many of the test stand's support structures - diffuser, liquid oxygen, isopropyl alcohol and water tanks and gaseous nitrogen bottle battery - had begun with the installation of (background) `mud slabs.' The slabs provide a working surface for the reinforcing steel and foundation forms.

The final structural steel beam, bearing flags and the names of project workers, is hoisted and fastened into place atop the A-3 Test Stand.

The rotating service structure on Launch Pad 39A has moved for the first time in more than a year due to maintenance and upgrades on the pad. Some of the work included sandblasting the structure to remove rust and repainting. In addition, the RSS was jacked up and a new upper-bearing race assembly installed where the RSS pivots against the fixed service structure and a half-inch steel plate added. Pad 39A is being made ready for its first launch in four years, the upcoming STS-117 on March 15.

In the early morning of Dec. 18, 2024, a crane looms over the 112-foot-wide (34-meter-wide) steel framework for Deep Space Station 23 (DSS-23) reflector dish, which will soon be lowered into position on the antenna's base structure. Located at the Deep Space Network's Goldstone Space Communications Complex near Barstow, California, DSS-23 is a multi-frequency beam waveguide antenna that will boost the DSN's capacity and enhance NASA's deep space communications capabilities for decades to come. In the background are, from left to right, the beam waveguide antennas DSS-25 and DSS-26, and the decommissioned 85-foot (26-meter) Apollo antenna. https://photojournal.jpl.nasa.gov/catalog/PIA26456

A multi-frequency beam waveguide antenna, DSS-23 will boost the DSN's capacity and enhance NASA's deep space communications capabilities for decades to come. Once online in 2026, DSS-23 will be the fifth of six new beam waveguide antennas to be added to the network, following DSS-53, which was added at the DSN's Madrid complex in 2022. After the reflector skeleton was bolted into place, engineers placed what's called a quadripod into the center of the structure. A four-legged support structure weighing 16 ½ tons, the quadripod is fitted with a curved subreflector that will direct radio frequency signals from deep space that bounce off the main reflector into the antenna's pedestal where the antenna's receivers are housed. Next steps: to fit panels onto the steel skeleton of the parabolic reflector to create a curved surface to collect radio frequency signals. The DSN allows missions to track, send commands to, and receive scientific data from faraway spacecraft. It is managed by NASA's Jet Propulsion Laboratory in Southern California for the agency's Space Communications and Navigation (SCaN) program, which is located at NASA Headquarters within the Space Operations Mission Directorate. https://photojournal.jpl.nasa.gov/catalog/PIA26454

A structural steel section is lifted into place atop the B-2 Test Stand at NASA’s Stennis Space Center as part of modification work to prepare for testing the core stage of NASA’s new Space Launch System. The section is part of the Main Propulsion Test Article (MPTA) framework, which will support the SLS core stage for testing. The existing framework was installed on the stand in the late 1970s to test the shuttle MPTA. However, that framework had to be repositioned and modified to accommodate the larger SLS stage. About 1 million pounds of structural steel has been added, extending the framework about 100 feet higher and providing a new look to the Stennis skyline. Stennis will test the actual flight core stage for the first uncrewed SLS mission, Exploration Mission-1.

CAPE CANAVERAL, Fla. -- At NASA's Kennedy Space Center in Florida, the rotating service structure (RSS) on Launch Pad 39B is being dismantled. Sand, reinforcing steel and large wooden mats were put down under the RSS to protect the structure's concrete from falling debris during deconstruction. Starting in 2009, the structure at the pad was no longer needed for NASA's Space Shuttle Program, so it is being restructured for future use. The new design will feature a "clean pad" for rockets to come with their own launcher, making it more versatile for a number of vehicles. The new lightning protection system, consisting of three lightning towers and a wire catenary system will remain. Photo credit: NASA/Jim Grossmann

CAPE CANAVERAL, Fla. -- The interior of NASA's new mobile launcher, or ML, support structure is outfitted with solid steel flooring, lights, air conditioning, electrical boxes and sprinkler piping at NASA's Kennedy Space Center in Florida. The 355-foot-tall structure will support NASA's future human spaceflight program. The base of the launcher is lighter than space shuttle mobile launcher platforms so the crawler-transporter can pick up the heavier load of the tower and a taller rocket. The next step will be to add ground support equipment, such as umbilicals and access arms, for future rocket launches. For information on NASA's future plans, visit www.nasa.gov.

At its founding, the Marshall Space Flight Center (MSFC) inherited the Army’s Jupiter and Redstone test stands, but much larger facilities were needed for the giant stages of the Saturn V. From 1960 to 1964, the existing stands were remodeled and a sizable new test area was developed. The new comprehensive test complex for propulsion and structural dynamics was unique within the nation and the free world, and they remain so today because they were constructed with foresight to meet the future as well as on going needs. Construction of the S-IC Static test stand complex began in 1961 in the west test area of MSFC, and was completed in 1964. The S-IC static test stand was designed to develop and test the 138-ft long and 33-ft diameter Saturn V S-IC first stage, or booster stage, weighing in at 280,000 pounds. Required to hold down the brute force of a 7,500,000-pound thrust produced by 5 F-1 engines, the S-IC static test stand was designed and constructed with the strength of hundreds of tons of steel and 12,000,000 pounds of cement, planted down to bedrock 40 feet below ground level. The foundation walls, constructed with concrete and steel, are 4 feet thick. The base structure consists of four towers with 40-foot-thick walls extending upward 144 feet above ground level. The structure was topped by a crane with a 135-foot boom. With the boom in the upright position, the stand was given an overall height of 405 feet, placing it among the highest structures in Alabama at the time. This photo, taken September 15, 1961, shows the installation of the reinforcing steel prior to the pouring of the concrete foundation walls.

Construction of the A-3 Test Stand at Stennis Space Center continued June 8 with installation of a 35,000-gallon liquid oxygen tank atop the steel structure. The stand is being built to test next-generation rocket engines that will carry humans into deep space once more. The LOX tank and a liquid hydrogen tank to be installed atop the stand later will provide propellants for testing the engines. The A-3 Test Stand is scheduled for completion and activation in 2013.

Stennis Space Center employees marked another construction milestone July 25 with installation of the 85,000-gallon liquid hydrogen tank atop the A-3 Test Stand. The 300-foot-tall stand is being built to test next-generation rocket engines that could carry humans into deep space once more. The liquid hydrogen tank and a 35,000-gallon liquid oxygen tank installed atop the steel structure earlier in June will provide fuel propellants for testing the engines.

CAPE CANAVERAL, Fla. -- A steel door, similar to a bank vault door, leads to the blast-resistant "rubber room" beneath Launch Pad 39B at NASA's Kennedy Space Center. The room is a steel dome floating on rubber isolators and was used as an escape route during the Apollo Program in case of an emergency. It has since been abandoned by astronauts, but throughout the years nature found its way inside, including raccoons, snakes, birds and even a bobcat and opossum. Starting in 2009, the structure above the room on the pad was no longer needed for NASA's Space Shuttle Program, so it is being restructured for future use.

An entranced youngster watches a demonstration of the enhanced resilience of undercooled metal alloys as compared to conventional alloys. Steel bearings are dropped onto plates made of steel, titanium alloy, and zirconium liquid metal alloy, so-called because its molecular structure is amorphous and not crystalline. The bearing on the liquid metal plate bounces for a minute or more longer than on the other plates. Experiments aboard the Space Shuttle helped scientists refine their understanding of the physical properties of certain metal alloys when undercooled (i.e., kept liquid below their normal solidification temperature). This new knowledge then allowed scientists to modify a terrestrial production method so they can now make limited quantities marketed under the Liquid Metal trademark. The exhibit was a part of the NASA outreach activity at AirVenture 2000 sponsored by the Experimental Aircraft Association in Oshkosh, WI.

jsc2023e010178 (4/7/2022) --- This image taken by a scanning electron microscope shows one of the ESA-Biofilms sample plates from its first launch to the International Space Station. The sample plate in this image is made of stainless steel, which is the reference surface in the experiment since it has no antimicrobial properties. This surface also has a 3 µm laser structure engraved to the surface as control. In contrast to the copper surface, there are many Staphylococcus capitis cells attached to the steel surface that are actively dividing and starting to from components of a biofilm matrix. The ESA-Biofilms investigation studies bacterial biofilm formation and antimicrobial properties of different metal surfaces under spaceflight conditions in altered gravity.

CAPE CANAVERAL, Fla. -- At NASA's Kennedy Space Center in Florida, cleanup of Launch Pad 39B is in progress beside the pad's flame trench. The trench is 450 feet long, 58 feet wide and 42 feet deep with an inner inverted V-shaped steel flame deflector. Sand, reinforcing steel and large wooden mats were placed over the pad's concrete surfaces during deconstruction to protect them from falling debris. In the distance is the 525-foot-tall Vehicle Assembly Building. In 2009, the structure at the pad was no longer needed for NASA's Space Shuttle Program, so it is being restructured for future use. The new design will feature a "clean pad" for rockets to come with their own launcher, making it more versatile for a number of rockets and spacecraft. The lightning protection system, consisting of three lightning towers and a wire catenary system, will remain. For information on NASA's future plans, visit http://www.nasa.gov/exploration.

Aerial view of the 8- by 6-Foot Supersonic Wind Tunnel in its original configuration at the National Advisory Committee for Aeronautics (NACA) Lewis Flight Propulsion Laboratory. The 8- by 6 was the laboratory’s first large supersonic wind tunnel. It was also the NACA’s most powerful supersonic tunnel, and its first facility capable of running an engine at supersonic speeds. The 8- by 6-foot tunnel has been used to study inlets and exit nozzles, fuel injectors, flameholders, exit nozzles, and controls on ramjet and turbojet propulsion systems. The 8- by 6 was originally an open-throat and non-return tunnel. This meant that the supersonic air flow was blown through the test section and out the other end into the atmosphere. In this photograph, the three drive motors in the structure at the left supplied power to the seven-stage axial-flow compressor in the light-colored structure. The air flow passed through flexible walls which were bent to create the desired speed. The test article was located in the 8- by 6-foot stainless steel test section located inside the steel pressure chamber at the center of this photograph. The tunnel dimensions were then gradually increased to slow the air flow before it exited into the atmosphere. The large two-story building in front of the tunnel was used as office space for the researchers.

Northward view of the Flight Research Building's steel framework in August 1941 as it neared completion at the National Advisory Committee for Aeronautics (NACA) Aircraft Engine Research Laboratory. The 272- by 150-foot hangar had a 90-foot clearance at its highest point. The hangar was the first structure built and was needed as a shelter for the growing staff, who occupied a nearby Farm House at this point. In January 1941 the Cleveland-area R.P. Carbone Construction Company was selected to build the hangar. Over the ensuing months, however, the NACA management became frustrated by the slow progress on the project. Although Carbone was contracted to complete the entire hangar by August, it was September before even the structural steel frame, seen in this photograph, was in place. Officials estimated the roof and siding were four months behind schedule. This was a serious concern because the lab’s research, support and administrative staff members would soon begin arriving. By mid-September the transite walls began enclosing the skeleton. In October work began on the temporary offices inside. The building was completed in mid-December just in time for the staff arriving from Langley.

CAPE CANAVERAL, Fla. – At Launch Pad 39A at NASA's Kennedy Space Center, workers on a platform spray a heat-resistant concrete called Fondue Fyre into steel grid structures, welded to the wall of the flame trench. Fondue Fyre was developed during NASA's Apollo lunar program. Damage to the trench occurred during the May 31 launch of Discovery on the STS-124 mission. A 75- by 20-foot section of the east wall was destroyed and debris scattered as far as the pad perimeter fence. Repairs are expected to be completed before the targeted Oct. 8 launch of Atlantis on the NASA Hubble Space Telescope servicing mission. Photo credit: NASA/Jack Pfaller
