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.

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 crane lifts the Core State Inter-tank Umbilical (CSITU) for NASA's Space Launch System (SLS) at the Launch Equipment Test Facility at the agency's Kennedy Space Center in Florida. The CSITU will be attached to the "C" tower of the Vehicle Motion Simulator 2 test fixture. The umbilical will undergo a series of tests to confirm it is functioning properly and ready to support the SLS rocket for launch. The CSITU is a swing arm umbilical that will connect to the SLS core stage inter-tank. The umbilical's main function is to vent gaseous hydrogen from the core stage. The arm also provides conditioned air, pressurized gases, and power and data connection to the core stage. The center’s Engineering Directorate and the Ground Systems Development and Operations Program are overseeing processing and testing of the umbilicals.

The OSMU was attached to Vehicle Motion Simulator 1 for a series of simulated launch tests to validate it for installation on the mobile launcher. The test team gathered with a special banner during an event to mark the end of testing. The mobile launcher tower will be equipped with a number of lines, called umbilicals that will connect to the Space Launch System rocket and Orion spacecraft for Exploration Mission-1 (EM-1). The OSMU will be located high on the mobile launcher tower and, prior to launch, will transfer liquid coolant for the electronics and air for the Environmental Control System to the Orion service module that houses these critical systems to support the spacecraft. Kennedy's Engineering Directorate is providing support to the Ground Systems Development and Operations Program for testing of the OSMU. EM-1 is scheduled to launch in 2018.

CAPE CANAVERAL, Fla. -- At NASA's Kennedy Space Center in Florida, testing of the Tilt-Up Umbilical Arm (TUUA) prototype's Environmental Control System Quick Disconnect takes place in the Launch Equipment Test Facility's 6,000-square-foot high bay. The prototype is used to demonstrate the safe disconnect and retraction of ground umbilical plates and associated hardware of a launch vehicle's upper stage and service module. The Environmental Control System consists of regulated air, which would be used to purge an inner tank and crew module. Since 1977, the facility has supported NASA’s Launch Services, shuttle, International Space Station, and Constellation programs, as well as commercial providers. The facility recently underwent a major upgrade to support even more programs, projects and customers. It houses a 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, 600-ton test fixture, launch simulation towers and a cryogenic system. Photo credit: NASA/Jack Pfaller

Crews test temporary contingency access platforms on the mobile launcher simulator tower on Wednesday, Oct. 29, 2025, at the Launch Equipment Test Facility at NASA’s Kennedy Space Center in Florida. The platforms will allow engineers to access the vehicle’s flight termination system on the rocket and the mobile launcher while at the pad rather than rolling back to the Vehicle Assembly Building to retest them. For Artemis II, four astronauts will venture around the Moon in early 2026, the first crewed mission on NASA’s path to establishing a long-term presence for science and exploration through Artemis.

CAPE KENNEDY, Fla. -- Inside the Launch Equipment Test Facility at NASA’s Kennedy Space in Florida, the Orion ground test vehicle has been transferred to a test stand and prepared for a pyrotechnic bolt test. 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.
