CAPE CANAVERAL, Fla. -- At NASA's Kennedy Space Center in Florida is the control room of the Launch Equipment Test Facility (LETF). The LETF recently underwent a $35 million comprehensive upgrade that lasted four years. The LETF was established in the 1970s to support the qualification of the Space Shuttle Program’s umbilical and T-0 mechanisms. Throughout the years, it has supported the development of systems for shuttle and the International Space Station, Delta and Atlas rockets, and various research and development programs. The LETF has unique capabilities to evolve into a versatile test and development area that supports a wide spectrum of programs. For information on NASA's future plans, visit www.nasa.gov.

CAPE KENNEDY, Fla. -- Inside the control room at the Launch Equipment Test Facility, or LETF, at NASA’s Kennedy Space Center in Florida, Lockheed Martin engineers monitor the pyrotechnic bolt test on the Orion ground test vehicle at the LETF. Lockheed Martin performed tests over a series of days on the explosive bolts that separate Orion from the launch abort system. Data was collected on the effect of shock waves on Orion during the explosive bolt separation. Orion is the exploration spacecraft designed to carry crews to space beyond low Earth orbit. It will provide emergency abort capability, sustain the crew during the space travel and provide safe re-entry from deep space return velocities. The first unpiloted test flight of the Orion is scheduled to launch in 2014 atop a Delta IV rocket and in 2017 on a Space Launch System rocket. For more information, visit http://www.nasa.gov/orion.

A view of one of the large test structures located at the Launch Equipment Test Facility (LETF) on Oct. 19, 2020, at NASA’s Kennedy Space Center in Florida. The LETF is a unique set of structures, equipment and tools built to test full-scale umbilicals and release mechanisms for the space shuttle. The facility also was used to test the umbilicals and other mechanisms for the mobile launcher. The mobile launcher will carry the Space Launch System and Orion spacecraft to Launch Pad 39B for Artemis I, a mission that will test the rocket and spacecraft as an integrated system ahead of crewed flights to the Moon. NASA will land the first woman and the next man on the Moon in 2024.

The first umbilical – one of many swing arms that will provide power, communications, and propellants to a larger configuration of NASA’s Space Launch System (SLS) rocket – for the agency’s mobile launcher 2 (ML2) arrives at the Launch Equipment Test Facility (LETF) at NASA’s Kennedy Space Center in Florida on Oct. 28, 2021. The umbilical will go through rounds of testing at the LETF to verify it functions properly before getting installed on the ML2 tower. This particular umbilical will provide propellants, environmental control systems, and a variety of purge gasses to the rocket’s Exploration Upper Stage. ML2 will be used to launch SLS Block 1B and Block 2 configurations to the Moon, starting with the Artemis IV mission, allowing NASA to send astronauts and heavy cargo to the lunar surface.

CAPE CANAVERAL, Fla. -- At NASA's Kennedy Space Center in Florida, training takes place atop a mast climber that is attached to launch simulation towers outside the Launch Equipment Test Facility. The training includes attaching carrier plates, water and air systems, and electricity to the climber to simulate working in Kennedy's Vehicle Assembly Building (VAB). Mast climbers can be substituted for fixed service structures currently inside the VAB to provide access to any type of launch vehicle. Since 1977, the facility has supported NASA’s Launch Services, shuttle, International Space Station, and Constellation programs, as well as commercial providers. Last year, the facility underwent a major upgrade to support even more programs, projects and customers. It houses a 6,000-square-foot high bay, cable fabrication and molding shop, pneumatics shop, machine and weld shop and full-scale control room. Outside, the facility features a water flow test loop, vehicle motion simulator and a cryogenic system. Photo credit: NASA/Jim Grossmann

CAPE CANAVERAL, Fla. -- At NASA’s Kennedy Space Center in Florida, Lockheed Martin crews begin uncovering the Orion ground test vehicle in the Launch Equipment Test Facility, or LETF. The GTA was moved from the Operations and Checkout Facility to the LETF for a series of pyrotechnic bolt tests. The GTA is being used for path finding operations in the O&C, including simulated manufacturing and assembly procedures. Launching atop NASA's heavy-lift Space Launch System SLS, which also is under development, the Orion Multi-Purpose Crew Vehicle MPCV will serve as the exploration vehicle that will carry astronaut crews beyond low Earth orbit. It also will provide emergency abort capabilities, sustain the crew during space travel and provide safe re-entry from deep space return velocities. For more information, visit www.nasa.gov/orion.

CAPE CANAVERAL, Fla. -- Inside the Launch Equipment Test Facility at NASA’s Kennedy Space in Florida, a second firing of the escape hold down post has occurred during a pyrotechnic bolt test on the Orion ground test vehicle. Lockheed Martin performed tests over a series of days on the explosive bolts that separate Orion from the launch abort system. Data was collected on the effect of shock waves on Orion during the explosive bolt separation. Orion is the exploration spacecraft designed to carry crews to space beyond low Earth orbit. It will provide emergency abort capability, sustain the crew during the space travel and provide safe re-entry from deep space return velocities. The first unpiloted test flight of the Orion is scheduled to launch in 2014 atop a Delta IV rocket and in 2017 on a Space Launch System rocket. For more information, visit http://www.nasa.gov/orion.

A crane lifts the first Tail Service Mast Umbilical (TSMU) up for placement on a test stand at the Launch Equipment Test Facility at NASA’s Kennedy Space Center in Florida. Two TSMUs will provide liquid propellants and power to the Space Launch System (SLS) rocket’s core stage engine. Both TSMUs will connect to the zero-level deck on the mobile launcher, providing fuel and electricity to the SLS rocket before it launches on Exploration Mission 1. The TSMU will undergo testing and validation at the LETF to verify it is functioning properly. The center’s Engineering Directorate and the Ground Systems Development and Operations Program are overseeing processing and testing of the umbilicals.
