A water tank is lifted into place at the A-3 Test Stand being built at NASA's John C. Stennis Space Center. Fourteen water, liquid oxygen (LOX) and isopropyl alcohol (IPA) tanks are being installed to support the chemical steam generators to be used on the A-3 Test Stand. The IPA and LOX tanks will provide fuel for the generators. The water will allow the generators to produce steam that will be used to reduce pressure inside the stand's test cell diffuser, enabling operators to simulate altitudes up to 100,000 feet. In that way, operators can perform the tests needed on rocket engines being built to carry humans back to the moon and possibly beyond. The A-3 Test Stand is set for completion and activation in 2011.

ISS014-E-18978 (5 April 2007) --- Astronaut Sunita L. Williams, Expedition 14 flight engineer, works with water tanks in the Progress 24 spacecraft docked to the International Space Station.

Kennedy Space Center’s Carolina Franco, Ph.D., weighs one of the water tanks, recently returned to the center after remaining on the International Space Station for the past five years, in the Florida spaceport’s Neil Armstrong Operations and Checkout Building on Nov. 13, 2019. Two tanks containing water were first sent to the orbiting laboratory in 2014 to study slosh, or the movement of water, in a zero-gravity environment to help engineers predict the movement of propellant in rocket tanks. Kennedy’s Air and Water Revitalization lab is studying the water tanks to determine if there is, or was, any microbial growth within them. The results will help NASA determine whether clean water can be stored in space for long-duration missions, an essential component to keeping astronauts safe and healthy as the agency prepares for missions to the Moon and beyond to Mars.

STS035-12-005 (2-10 Dec 1990) --- During STS-35, middeck stowage volume G and a contingency water container (CWC) were utilized to remedy a problem onboard Columbia, Orbiter Vehicle (OV) 102. A hose connecting OV-102's waste water system to the CWC was used in order to bypass a suspected clog in the line from the waste water tank to the exit nozzle. On flight day seven, Pilot Guy S. Gardner carried out an inflight maintenance (IFM) procedure by connecting a spare hose from the line to the container. The CWC is a rubber-lined duffle bag that holds about 95 pounds of water and is used in situations where water cannot be dumped overboard normally.

STS055-39-036 (26 April-6 May 1993) --- Astronaut Terence T. (Tom) Henricks, pilot, uses a spotlight and pen to point out a possible problem area on a waste water tank in the bilge area below Columbia's middeck. Astronaut Jerry L. Ross, payload commander, records the activity with a camera.

Stennis Space Center engineers are preparing to conduct water tests on an updated version of the scissors duct component of the J-2X engine. Measuring about 2 feet long and about 8 inches in diameter, the duct on the J-2X predecessor, the J-2, connected its fuel turbo pumps to the flight vehicle's upper stage run tanks. According to NASA's J-2X project manager at SSC, Gary Benton, the water tests should establish the limits of the duct's ability to withstand vibration.

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. In addition to the stand itself, related facilities were constructed during this time. Built to the northeast east was a newly constructed Pump House. Its function was to provide water to the stand to prevent melting damage during testing. The water was sprayed through small holes in the stand’s 1900 ton flame deflector at the rate of 320,000 gallons per minute. This photograph of the Pump House area was taken August 13, 1963. The massive round water storage tanks can be seen to the left of the Pump House.

Photo shows how the Space Launch Sysetm (SLS) rocket liquid oxygen tank failed during a structural qualification test at NASA’s Marshall Space Flight Center in Huntsville, Alabama. The photos show both the water flowing from the tank as it ruptured and the resultant tear left in the tank when it buckled during the test. Engineers pushed the liquid oxygen structural test article to the limits on purpose. The tank is a test article that is identical to tanks that are part of the SLS core stage that will produce 2 million pounds of thrust to help launch the rocket on the Artemis missions to the Moon. During the test, hydraulic cylinders were then calibrated and positioned along the tank to apply millions of pounds of crippling force from all sides while engineers measured and recorded the effects of the launch and flight forces. For the test, water used to simulate the liquid oxygen flows out of the tank after it ruptures. The structural test campaign was conducted on the rocket to ensure the SLS rocket’s structure can endure the rigors of launch and safely send astronauts to the Moon on the Artemis missions.

Teams at NASA’s Michoud Assembly Facility in New Orleans successfully completed hydrostatic proof testing of the core stage liquid oxygen tank for the agency’s Artemis III mission. The non-destructive evaluation method tests the structural integrity of the tank’s welds by filling the tank with water, simulating the propellant used during launch. The hardware was then moved to an adjacent cell for internal cleaning. Next, the tank will be readied for primer and application of its thermal protection system. The propellant tank is one of five major elements that make up the 212-foot-tall rocket stage. The core stage, along with its four RS-25 engines, produce two million pounds of thrust to help launch NASA’s Orion spacecraft, astronauts, and supplies beyond Earth’s orbit and to the lunar surface for Artemis.

The core stage liquid hydrogen tank for the Artemis III mission completed proof testing, and technicians returned it to the main factory building at NASA’s Michoud Assembly Facility in New Orleans where it will undergo more outfitting. As part of proof testing, technicians apply a simple soap solution and check for leaks by observing any bubble formation on the welds. The technician removed the bubble solution with distilled water and then dried the area of application to prevent corrosion. To build the Space Launch System (SLS) rocket’s 130-foot core stage liquid hydrogen tank, engineers use robotic tools to weld five-barrel segments. This process results in a tank with around 1,900 feet, or more than six football fields, of welds that must be tested by hand. After the leak tests, the core stage lead, Boeing, pressurized the SLS tank to further ensure there were no leaks. After it passed proof testing, technicians moved the Artemis III liquid hydrogen tank to Michoud’s main factory. Soon, the technicians will prime and apply a foam-based thermal protection system that protects the tank during launch. Later, the tank will be joined with other parts of the core stage to form the entire 212-foot rocket stage with its four RS-25 engines that produce 2 million pounds of thrust to help launch the rocket. Artemis III will land the first astronauts on the lunar surface.

A liquid oxygen (LOX) tank is lifted into place at the A-3 Test Stand being built at NASA's John C. Stennis Space Center. Fourteen LOX, isopropyl alcohol (IPA) and water tanks are being installed to support the chemical steam generators to be used on the A-3 Test Stand. The IPA and LOX tanks will provide fuel for the generators. The water will allow the generators to produce steam that will be used to reduce pressure inside the stand's test cell diffuser, enabling operators to simulate altitudes up to 100,000 feet. In that way, operators can perform the tests needed on rocket engines being built to carry humans back to the moon and possibly beyond. The A-3 Test Stand is set for completion and activation in 2011.

The STS-95 Space Shuttle Discovery sits on the Mobile Launch Platform, still atop the crawler transporter, at Launch Pad 39B. To its left is the Fixed Service Structure that provides access to the orbiter and the Rotating Service Structure. To its right is the elevated water tank, with a capacity of 300,000 gallons. Part of the sound suppression water system, the tank stands 290 feet high on the northeast side of the pad. Water from the tank is released just before ignition of the orbiter's three main engines and twin solid rocket boosters. The entire system reduces the acoustical levels within the orbiter's payload bay to an acceptable 142 decibels. Beyond the orbiter is seen the Atlantic Ocean. While at the launch pad, the orbiter, external tank and solid rocket boosters will undergo final preparations for the launch, scheduled to lift off Oct. 29. The mission includes research payloads such as the Spartan solar-observing deployable spacecraft, the Hubble Space Telescope Orbital Systems Test Platform, the International Extreme Ultraviolet Hitchhiker, as well as the SPACEHAB single module with experiments on space flight and the aging process

The Saturn I (SA-3) flight lifted off from Kennedy Space Center launch Complex 34, November 16, 1962. The third launch of Saturn launch vehicles, developed at the Marshall Space Flight Center (MSFC) under the direction of Dr. Wernher von Braun, incorporated a Saturn I, Block I engine. The typical height of a Block I vehicle was approximately 163 feet. and had only one live stage. It consisted of eight tanks, each 70 inches in diameter, clustered around a central tank, 105 inches in diameter. Four of the external tanks were fuel tanks for the RP-1 (kerosene) fuel. The other four, spaced alternately with the fuel tanks, were liquid oxygen tanks as was the large center tank. All fuel tanks and liquid oxygen tanks drained at the same rates respectively. The thrust for the stage came from eight H-1 engines, each producing a thrust of 165,000 pounds, for a total thrust of over 1,300,000 pounds. The engines were arranged in a double pattern. Four engines, located inboard, were fixed in a square pattern around the stage axis and canted outward slightly, while the remaining four engines were located outboard in a larger square pattern offset 40 degrees from the inner pattern. Unlike the inner engines, each outer engine was gimbaled. That is, each could be swung through an arc. They were gimbaled as a means of steering the rocket, by letting the instrumentation of the rocket correct any deviations of its powered trajectory. The block I required engine gimabling as the only method of guiding and stabilizing the rocket through the lower atmosphere. The upper stages of the Block I rocket reflected the three-stage configuration of the Saturn I vehicle. During the SA-3 flight, the upper stage ejected 113,560 liters (30,000 gallons) of ballast water in the upper atmosphere for "Project Highwater" physics experiment. The water was released at an altitude of 65 miles, where within only 5 seconds, it expanded into a massive ice cloud 4.6 miles in diameter. Release of this vast quantity of water in a near-space environment marked the first purely scientific large-scale experiment.

At right of the pad is the 290-foot-tall water tower that holds 300,000 gallons of water, part of the sound suppression system during a launch. Discovery will be rolled back to the Vehicle Assembly Building. Once inside the VAB, Discovery will be demated from its External Tank and lifted into the transfer aisle. On or about June 7, Discovery will be lifted and attached to its new tank and Solid Rocket Boosters, which are already in the VAB. Only the 15th rollback in Space Shuttle Program history, the 4.2-mile journey allows additional modifications to be made to the External Tank prior to a safe Return to Flight. Discovery is expected to be rolled back to the launch pad in mid-June for Return to Flight mission STS-114. The launch window extends from July 13 to July 31.

CAPE CANAVERAL, Fla. - At NASA’s Kennedy Space Center in Florida, preparations are underway to sandblast and paint the 290-foot-high water tower at Launch Pad 39B. Scaffolding surrounds the tower and a special covering has been placed around the tank. The water towers at Launch Complex 39, which includes pad A and B, were part of the sound suppression system used during space shuttle launches. Water stored in the 300,000-gallon tank would be released just prior to main engine ignition and flow by gravity to special mobile launcher platform (MLP) outlets. Nine seconds after shuttle liftoff, the peak flow rate was 900,000 gallons per minute and helped to protect the orbiter and payloads from being damaged by acoustical energy reflected from the MLP during liftoff.

Also, the hydraulic portion of the valve actuators has been redesigned and simplified to reduce maintenance costs. The sound suppression water system is installed on the launch pads to protect the orbiter and its payloads from damage by acoustical energy reflected from the MLP during launch. The system includes an elevated water tank with a capacity of 300,000 gallons. The tank is 290 feet high and stands on the northeast side of the Pad. The water is released just before the ignition of the orbiter's three main engines and twin solid rocket boosters, and flows through parallel 7-foot-diameter pipes to the Pad area.

KENNEDY SPACE CENTER, FLA. -- For the fourth time in Space Shuttle Program history, 350,000 gallons of water are released on a Mobile Launcher Platform (MLP) at Launch Pad 39A during a water sound suppression test.

The barge's cargo is the external tank prepared for mission STS-118 by the Michoud Assembly Facility near New Orleans. Visible at right is one of the launch pads and the nearby water tower. The destination of the barge is the turn basin near the Vehicle Assembly Building where the tank will be offloaded and moved to the VAB. Photo credit: Dimitri Gerondidakis

KENNEDY SPACE CENTER, Fla. -- A long view of Launch Complex 39 is caught by the early morning sun. Left of center is Launch Pad 39A with Space Shuttle Discovery. At its left is the 300,000-gallon water tank that is part of the sound suppression system. Hoses from the tank can be seen coiling under the pad, next to the opening of the flame trench, part of the flame detector system. In the foreground is a retention pond; another is at right center. At far right, the ball-shaped structure is a 850,000-gallon storage tank for the cryogenic liquid oxygen, one of the propellants of the orbiter’s main engines. On the horizon can be seen the 525-foot tall Vehicle Assembly Building

Space Shuttle Discovery sits atop the Mobile Launch Platform on Launch Pad 39-B, with the Rotating Service Structure moved back, to await rollback decision. At the right is the 300,000-gallon water tank, part of the sound suppression water system used during launch. KSC managers developed a precautionary plan to roll back Discovery to the Vehicle Assembly Building in the event that Hurricane Georges threatens Central Florida. The decision was made in order to minimize risk and provide protection to the Space Shuttle, a national asset
