CS1 LH2 Move into Area 47

Build-up of a new liquid hydrogen (LH2) storage tank is in progress on Oct. 1, 2019, at Launch Complex 39B at NASA's Kennedy Space Center in Florida. The new tank will hold 1.25 million gallons of usable LH2 to support future launches from the pad, including Artemis missions to the Moon and on to Mars.

Seen here is a newly constructed liquid hydrogen (LH2) storage tank at Launch Pad 39B at NASA’s Kennedy Space Center in Florida on Oct. 1, 2021. With construction now complete, teams will focus on painting the tank next. The storage tank, capable of holding 1.25 million gallons of LH2, will be used to support future Artemis missions to the Moon and, eventually, Mars. Through Artemis, NASA will land the first woman and first person of color on the Moon, paving the way for a long-term presence in lunar orbit.

A new liquid hydrogen separator tank arrives at NASA's Kennedy Space Center in Florida. The tank will be lifted and rotated for delivery to Launch Pad 39B. The new separator/storage tank will be added to the pad's existing hydrogen vent system to assure gaseous hydrogen is delivered downstream to the flare stack. The 60,000 gallon tank was built by INOXCVA, in Baytown, Texas, a subcontractor of Precision Mechanical Inc. in Cocoa Florida. The new tank will support all future launches from the pad.

Teams move the core stage liquid hydrogen tank for the Artemis III mission to a priming cell near the Vertical Assembly Building at NASA’s Michoud Assembly Facility in New Orleans Nov. 21. Technichians will sand down and prepare the suface of the tank before coating it in a primer. Primer is applied to the barrel section of the tank by an automated robotic tool, whereas the forward and aft domes are primed manually. Once priming is complete, technicians with NASA and Boeing, the SLS core stage prime contractor, will apply a foam-based thermal protection system, which protects the propellant tank from the extreme temperatures it will face during launch and flight while also regulating the super-chilled propellant within it. 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.

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

CAPE CANAVERAL, Fla. – At Launch Pad 39B at NASA’s Kennedy Space Center in Florida, the liquid oxygen, or LOX, and liquid hydrogen, or LH2, tanks that supported space shuttle launches for 30 years have been sandblasted, repaired and repainted. The two tanks, designed to store super-cooled LOX and LH2, were refurbished to prepare them to support the launch of NASA’s Space Launch System and other launch vehicles. The Ground Systems Development and Operations, or GSDO, Program office at Kennedy is leading the center’s transformation to safely handle a variety of rockets and spacecraft.

KENNEDY SPACE CENTER, FLA. -- A small ruler shows the relative size of the bent LH2 recirculation line in Space Shuttle Discovery's engine compartment. Underneath the line is material draped to protect other components. The 12-inch-long dent was discovered during routine aft compartment inspections Tuesday, Dec. 7. The LH2 line recirculates hydrogen from the Shuttle main engines back to the external tank during prelaunch engine conditioning. The line is being replaced and managers expect the replacement work to take about 3 days, followed by system retests and final aft compartment close-outs. Preliminary assessments reflect a launch date of Space Shuttle Discovery on mission STS-103 no earlier than Dec. 16. STS-103 is the third servicing mission for the Hubble Space Telescope

The line recirculates hydrogen from the Shuttle main engines back to the external tank during prelaunch engine conditioning. Workers noted a dent in the line during routine aft compartment inspections Tuesday, Dec. 7. The dent measures 12 inches long and about ½-inch deep. Managers expect the replacement work to take about 3 days, followed by system retests and final aft compartment close-outs.

The liquid hydrogen tank that will be part of the Space Launch System rocket’s core stage is being prepared for the Artemis III mission at NASA’s Michoud Assembly Facility in New Orleans. Eventually, the tank will be connected to the engine section that will house the four RS-25 engines. Once the aft simulator is attached, the LH2 tank undergoes non-destructive evaluation, which will test weld strength and ensure the tank is structurally sound. The SLS core stage is made up of five unique elements: the forward skirt, liquid oxygen tank, intertank, liquid hydrogen tank, and the engine section. The tank holds 537,000 gallons of liquid hydrogen cooled to minus 432 degrees Fahrenheit and sits between the core stage’s intertank and engine section. The liquid hydrogen hardware, along with the liquid oxygen tank, will provide propellant to the four RS-25 engines at the bottom of the core stage to produce more than two million pounds of thrust to help launch the Artemis III mission to the Moon. Together with its four RS-25 engines, the rocket’s massive 212-foot-tall core stage — the largest stage NASA has ever built — and its twin solid rocket boosters will produce 8.8 million pounds of thrust to send NASA’s Orion spacecraft, astronauts and supplies beyond Earth’s orbit to the Moon.

KENNEDY SPACE CENTER, FLA. -- Columbia's engine no. 2 is about to be pulled from the orbiter. After small cracks were discovered on the LH2 Main Propulsion System (MPS) flow liners in two other orbiters, program managers decided to move forward with inspections on Columbia before clearing it for flight on STS-107. The heat shields were removed, and after removing the three main engines, inspections of the flow liners will follow. The July 19 launch of Columbia on STS-107 has been delayed a few weeks

At Cape Canaveral Air Force skid strip, the Centaur upper stage is placed aboard a transporter after arriving aboard a Russian cargo plane, the Antenov 124. The Centaur will be coupled with an Atlas IIA to launch the latest Tracking and Data Relay Satellite (TDRS) June 29 from Cape Canaveral Air Force Station. The Centaur, manufactured and operated by Lockheed Martin, is 3.05 m (10 ft) in diameter and 10.0 m (33-ft) long. It uses liquid hydrogen (LH2) and liquid oxygen (LO2) propellants
