NACOGDOCHES, Texas -- A round 40-inch aluminum storage tank from space shuttle Columbia's Power Reactant and Storage Distribution System rests on the edge of Lake Nacogdoches in Texas. Lower lake water levels due to a local drought allowed the debris to become exposed. Columbia was destroyed during re-entry at the conclusion of the STS-107 mission in 2003. Approximately 38 to 40 percent of Columbia was recovered following the accident in a half-million-acre search area which extended from eastern Texas and to western Louisiana. This tank is one of 18 cryogenic liquid storage tanks that flew aboard Columbia. The tank is not hazardous to people or the environment and will be transported to NASA's Kennedy Space Center for storage inside the Vehicle Assembly Building with the rest of the recovered Columbia debris.

These photos show how teams at NASA’s Marshall Space Flight Center in Huntsville, Alabama, are testing an innovative approach to achieve zero boiloff storage of liquid hydrogen using two stages of active cooling, which could prevent the loss of valuable propellant during future long-duration spaceflight missions. Test teams installed the propellant tank in Test Stand 300 at NASA Marshall in early June, and the 90-day test campaign is scheduled to conclude in September. The tank is wrapped in a multi-layer insulation blanket that includes a thin aluminum heat shield fitted between layers. A second set of tubes, carrying helium at about minus 298 Fahrenheit, is integrated into the shield. This intermediate cooling layer intercepts and rejects incoming heat before it reaching the tank, easing the heat load on the tube-on-tank system. The Cryogenic Fluid Management Portfolio Project is a cross-agency team based at NASA Marshall and the agency’s Glenn Research Center in Cleveland. The cryogenic portfolio’s work is under NASA’s Technology Demonstration Missions Program, part of NASA’s Space Technology Mission Directorate, and is comprised of more than 20 individual technology development activities.

CAPE CANAVERAL, Fla. -- In the Launch Complex 39 area at NASA's Kennedy Space Center in Florida is a liquid hydrogen, or LH2, storage tank. This large ball-shaped, vacuum-jacketed tank is used to store cryogenic propellants for the space shuttle's orange external fuel tank. The LH2 tank is located at the northeast corner of Launch Pad 39A and stores 850,000 gallons of LH2 at a temperature of minus 423 degrees F. The shuttle's external tank is loaded with about 500,000 gallons of LH2 and liquid oxygen, or LOX, about six hours prior to launch in a process known as 'tanking.' Photo credit: NASA_Frankie Martin

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
These photos show how teams at NASA’s Marshall Space Flight Center in Huntsville, Alabama, are testing an innovative approach to achieve zero boiloff storage of liquid hydrogen using two stages of active cooling, which could prevent the loss of valuable propellant during future long-duration spaceflight missions. Test teams installed the propellant tank in Test Stand 300 at NASA Marshall in early June, and the 90-day test campaign is scheduled to conclude in September. The tank is wrapped in a multi-layer insulation blanket that includes a thin aluminum heat shield fitted between layers. A second set of tubes, carrying helium at about minus 298 Fahrenheit, is integrated into the shield. This intermediate cooling layer intercepts and rejects incoming heat before it reaching the tank, easing the heat load on the tube-on-tank system. The Cryogenic Fluid Management Portfolio Project is a cross-agency team based at NASA Marshall and the agency’s Glenn Research Center in Cleveland. The cryogenic portfolio’s work is under NASA’s Technology Demonstration Missions Program, part of NASA’s Space Technology Mission Directorate, and is comprised of more than 20 individual technology development activities.

The Tail Service Mast Umbilicals that will connect to NASA’s Space Launch System (SLS) rocket, containing fluid lines for liquid oxygen and liquid hydrogen propellant loading, are photographed on the mobile launcher at Launch Pad 39B on Nov. 8, 2019, at the agency’s Kennedy Space Center in Florida. NASA’s Exploration Ground Systems oversaw testing of the pad’s cryogenic systems – the infrastructure that will support the flow of liquid hydrogen and liquid oxygen from the storage tanks to the rocket – in preparation for the launch of SLS with the Orion spacecraft atop for the uncrewed Artemis I mission. Each of the liquid oxygen and liquid hydrogen tanks can hold more than 800,000 gallons of propellant. The liquid oxygen will require the use of pumps to push it from the tank to the rocket, while the lighter liquid hydrogen will make its way up to the pad using gaseous hydrogen to pressurize the sphere.
The control panel that will direct and control the flow of liquid oxygen and liquid oxygen, referred to as a skid, is photographed at Launch Pad 39B on Nov. 8, 2019, at NASA’s Kennedy Space Center in Florida.

CAPE CANAVERAL, Fla. – Inside the Space Station Processing Facility at NASA’s Kennedy Space Center in Florida, cold storage team members pack an International Space Station experiment cryogenic freezer called a Glacier unit, for transport to Space Launch Complex-40 at Cape Canaveral Air Force Station. The unit is for an experiment late-load demonstration test with the Space Exploration Technologies Corp. SpaceX Falcon 9 rocket and Dragon capsule. SpaceX is one of two companies under contract with NASA to take cargo to the International Space Station. NASA is working with SpaceX to combine its last two demonstration flights, and if approved, the Falcon 9 would launch the Dragon capsule to the orbiting laboratory for a docking within the next several months.

Technicians at work in the Materials Processing Laboratory’s Creep Facility at the National Aeronautics and Space Administration (NASA) Lewis Research Center. The technicians supported the engineers’ studies of refractory materials, metals, and advanced superalloys. The Materials Processing Laboratory contained laboratories and test areas equipped to prepare and develop these metals and materials. The ultra-high vacuum lab, seen in this photograph, contained creep and tensile test equipment. Creep testing is used to study a material’s ability to withstand long durations under constant pressure and temperatures. The equipment measured the strain over a long period of time. Tensile test equipment subjects the test material to strain until the material fails. The two tests were used to determine the strength and durability of different materials. The Materials Processing Laboratory also housed arc and electron beam melting furnaces, a hydraulic vertical extrusion press, compaction and forging equipment, and rolling mills and swagers. There were cryogenic and gas storage facilities and mechanical and oil diffusion vacuum pumps. The facility contained both instrumental and analytical chemistry laboratories for work on radioactive or toxic materials and the only shop to machine toxic materials in the Midwest.
Operation of the High Energy Rocket Engine Research Facility (B-1), left, and Nuclear Rocket Dynamics and Control Facility (B-3) at the National Aeronautics and Space Administration’s (NASA) Plum Brook Station in Sandusky, Ohio. The test stands were constructed in the early 1960s to test full-scale liquid hydrogen fuel systems in simulated altitude conditions. Over the next decade each stand was used for two major series of liquid hydrogen rocket tests: the Nuclear Engine for Rocket Vehicle Application (NERVA) and the Centaur second-stage rocket program. The different components of these rocket engines could be studied under flight conditions and adjusted without having to fire the engine. Once the preliminary studies were complete, the entire engine could be fired in larger facilities. The test stands were vertical towers with cryogenic fuel and steam ejector systems. B-1 was 135 feet tall, and B-3 was 210 feet tall. Each test stand had several levels, a test section, and ground floor shop areas. The test stands relied on an array of support buildings to conduct their tests, including a control building, steam exhaust system, and fuel storage and pumping facilities. A large steam-powered altitude exhaust system reduced the pressure at the exhaust nozzle exit of each test stand. This allowed B-1 and B-3 to test turbopump performance in conditions that matched the altitudes of space.
