John C. Stennis Space Center, America's largest rocket engine test complex, and one of the country's leading consumers of liquid hydrogen, was the location Feb. 27 for a fuel stop of three Mercedes B-Class F-CELL vehicles. The B-Class F-CELL is an electric vehicle, which is powered by electricity produced on board the vehicle from hydrogen gas. The only emission by this unique vehicle is pure water vapor. Due to the limited number of existing hydrogen locations, Stennis Space Center provided a logical choice for a refueling location as the vehicle made its way across the United States as part of a worldwide tour.

Technicians use an overhead crane to lower NASA Juno spacecraft onto a fueling stand where the spacecraft will be loaded with the propellant necessary for its mission to Jupiter.

jsc2024e021222 (3/21/2024) --- Solid Fuel Ignition and Extinction (SoFIE) insert supports the Growth and Extinction Limit (GEL) investigation test image taken in the Combustion Integrated Rack (CIR). This image was taken just prior to flame extinction while the green LED was flashing on. The LED allows the fuel surface to be seen during the burn, so that several important parameters can be evaluated, such as how far the flame is from the fuel and how much the fuel is heating up. The igniter wire appears in the camera view, but it is in the foreground and not near the flame. In the background on the left, an unburned acrylic sphere waits for its turn to be tested on another day.

The fuel tank assembly of the Saturn V S-IC (first) stage is readied to be mated to the liquid oxygen tank at the Marshall Space Flight Center. The fuel tank carried kerosene as its fuel. The S-IC stage utilized five F-1 engines that used kerosene and liquid oxygen as propellant. Each engine provided 1,500,000 pounds of thrust. This stage lifted the entire vehicle and Apollo spacecraft from the launch pad.

The components of the Saturn V booster (S-IC stage) fuel tank are shown in this photograph. The liquid oxygen tank bulkhead on the left and both halves of the fuel tank were in the Marshall Space Flight Center (MSFC) Manufacturing Engineering Laboratory, building 4707. These components were used at MSFC in structural testing to prove that they could withstand the forces to which they were subjected in flight. Each S-IC stage has two tanks, one for kerosene and one for liquid oxygen, made from such components as these. Thirty-three feet in diameter, they hold a total of 4,400,000 pounds of fuel. Although this tankage was assembled at MSFC, the elements were made by the Boeing Company at Wichita and the Michoud Operations at New Orleans.

An Astro Camp counselor and her campers perform a science experiment to learn what types of `fuel' will best propel their 'rockets.' Stennis Space Center's popular series of day camps have campers design, build and test model rockets based on the principles that would be used to build different types of rockets suitable for a mission to the moon or Mars. They learn details like how far they would travel, how long it would take, what supplies they would need and how to survive in that environment.
![A researcher at the National Advisory Committee for Aeronautics (NACA) Aircraft Engine Research Laboratory studies the fuel ignition process. Improved fuels and lubrication was an area of particular emphasis at the laboratory during World War II. The military sought to use existing types of piston engines in order to get large numbers of aircraft into the air as quickly as possible. To accomplish its goals, however, the military needed to increase the performance of these engines without having to wait for new models or extensive redesigns. The Aircraft Engine Research Laboratory was called on to lead this effort. The use of superchargers successfully enhanced engine performance, but the resulting heat increased engine knock [fuel detonation] and structural wear.

CAPE CANAVERAL, Fla. – Inside Orbiter Processing Facility-2 at NASA's Kennedy Space Center in Florida, a crane hoists one of space shuttle Endeavour's three fuel cells out of the vehicle's payload bay. All three of Endeavour's fuel cells were removed and will be drained of fluids. The hydrogen and oxygen dewars which feed reactants to the fuel cells remain in Endeavour's midbody and will be purged with inert gases and vented down. The work is part of the Space Shuttle Program's transition and retirement processing of shuttle Endeavour, which is being prepared for public display at the California Science Center in Los Angeles. Its ferry flight to California is targeted for mid-September. Endeavour was the last space shuttle added to NASA's orbiter fleet. Over the course of its 19-year career, Endeavour spent 299 days in space during 25 missions. For more information, visit http://www.nasa.gov/shuttle. Photo credit: NASA/Glenn Benson

Engineers at Marshall Space Flight Center (MSFC) in Huntsville, Alabama, are working with industry partners to develop a new generation of more cost-efficient space vehicles. Lightweight fuel tanks and components under development will be the critical elements in tomorrow's reusable launch vehicles and will tremendously curb the costs of getting to space. In this photo, Tom DeLay, a materials processes engineer for MSFC, uses a new graphite epoxy technology to create lightweight cryogenic fuel lines for futuristic reusable launch vehicles. He is wrapping a water-soluble mandrel, or mold, with a graphite fabric coated with an epoxy resin. Once wrapped, the pipe will be vacuum-bagged and autoclave-cured. The disposable mold will be removed to reveal a thin-walled fuel line. In addition to being much lighter and stronger than metal, this material won't expand or contract as much in the extreme temperatures encountered by launch vehicles.

Its ferry flight to California is targeted for mid-September. Endeavour was the last space shuttle added to NASA's orbiter fleet. Over the course of its 19-year career, Endeavour spent 299 days in space during 25 missions. For more information, visit http://www.nasa.gov/shuttle. Photo credit: NASA/Glenn Benson

Marshall Space Flight Center successfully conducted hydrostatic testing on the Saturn V S-IC (first) stage fuel tank. The first stage was powered by five F-1 engines, that used liquid oxygen and kerosene as its propellant.

Image taken during a ground based investigation of a methane-fueled laminar flame surrounded by co-flowing air. The flame was enclosed in a chamber, and the pressure reduced. As the pressure decreased, the velocity of the flow increased, causing the flame to change from a stabilized condition to near blow-out or extinction.

A truck containing the Robotic Refueling Mission-3 (RRM3) payload departs the Fuel Transfer Building near the Payload Hazardous Servicing Facility for transport to the SpaceX facility on Oct. 30, 2018, at NASA's Kennedy Space Center in Florida. The payload will be carried to the International Space Station on SpaceX's 16th Commercial Resupply Services mission. RRM3 demonstrates the transfer of xenon gas and liquid methane in microgravity, and advances technologies for storing and manipulating these cryogenic fuels robotically. RRM3 also supports development of technology for the Restore-L mission, a robotic spacecraft equipped to service satellites in-orbit.

CAPE CANAVERAL, Fla. -- Inside Orbiter Processing Facility-1 at NASA’s Kennedy Space Center in Florida, technicians monitor the progress as space shuttle Discovery’s fuel cells are drained of all fluids. After all of the coolant is removed, the fuel cells will be returned to their previous location within Discovery’s mid-body. The hydrogen and oxygen dewars which feed reactants to the fuel cells remain in Discovery’s mid-body and have been purged with inert gases and vented down. The work is part of the Space Shuttle Program’s transition and retirement processing of shuttle Discovery. Discovery is being prepared for display at the Smithsonian’s National Air and Space Museum, Steven F. Udvar-Hazy Center in Chantilly, Va. For more information, visit http://www.nasa.gov/shuttle.
