This image shows teams at NASA’s Michoud Assembly Facility in New Orleans lifting a forward skirt out of its vertical assembly center on Jan. 31, 2025. The forward skirt, which will be used on the core stage for the agency’s SLS (Space Launch System) rocket for its Artemis IV mission, houses flight computers, cameras, and avionics. While inside the vertical assembly center, technicians attached the forward skirt’s forward and aft rings, which serve as attachments points to the launch vehicle stage adapter and the liquid oxygen tank, respectively. The forward skirt 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 more than 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.

This image shows the forward skirt that will be used on the core stage of NASA’s Space Launch System rocket for Artemis II, the first crewed mission of NASA’s Artemis program, at NASA’s Michoud Assembly Facility. 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 forward skirt houses flight computers, cameras, and avionics systems. The hardware is located at the top of the 212-foot-tall core stage and connects the upper part of the rocket to the core stage. Soon, technicians will ready the forward skirt for the first of three core stage assembly mates called the forward join. The forward join consists of three main parts -- the forward skirt, liquid oxygen tank, and intertank – to create the top, or forward part, of the core stage. 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 and, ultimately, Mars. Offering more payload mass, volume capability and energy to speed missions through space, the SLS rocket, along with NASA’s Gateway in lunar orbit, the human landing system, and Orion spacecraft, is part of NASA’s backbone for deep space exploration and the Artemis lunar program. No other rocket is capable of carrying astronauts in Orion around the Moon in a single mission. Image credit: NASA/Michael DeMocker

When fully stacked, the forward skirt is located at the top of the core stage and connects the stage to the upper part of the rocket. 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 produce 8.8 million pounds of thrust to send NASA’s Orion spacecraft, astronauts and supplies beyond Earth’s orbit to the Moon and, ultimately, Mars. Offering more payload mass, volume capability and energy to speed missions through space, the SLS rocket, along with NASA’s Gateway in lunar orbit, the Human Landing System, and Orion spacecraft, is part of NASA’s backbone for deep space exploration and the Artemis lunar program. No other rocket is capable of carrying astronauts in Orion around the Moon in a single mission.

CAPE CANAVERAL, Fla. – In the Assembly and Refurbishment Facility at NASA's Kennedy Space Center in Florida, technicians keep watch as a crane lowers the Ares I-X forward skirt toward the forward skirt extension for mating. The forward skirt is the initial piece of first-stage hardware in preparation for the August 2009 test flight of NASA's next-generation spacecraft and launch vehicle system. Built entirely of armored steel, the 14,000-pound segment is seven feet tall and 12-1/4 feet wide. Photo credit: NASA/Tim Jacobs

Teams at NASA’s Michoud Assembly Facility in New Orleans move the forward skirt, which will be used on the SLS (Space Launch System) rocket’s core stage for the agency’s Artemis IV mission, into the vertical assembly center on Dec. 2. Inside the tooling, the forward skirt receives its forward and aft rings through a circumferential friction-stir welding process. Seven rings are used in the production of the core stage. They provide stiffening for the dome structures on the propellant tanks and, as on the forward skirt, serve as attachment points for the major components to form the SLS core stage. The forward skirt 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 more than 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.

A NASA engineer signs the banner inside a support building at the Launch Equipment Test Facility at Kennedy Space Center in Florida. Testing of the Core Stage Forward Skirt Umbilical (CSFSU) for NASA's Space Launch System is complete and the umbilical has been transported to the mobile launcher area. The umbilical will be prepared for installation on the tower of the mobile launcher. The CSFSU will be mated to the core stage forward skirt to provide commodities to the SLS rocket, and then disconnect and swing away before launch. Its main purpose is to provide conditioned air and gaseous nitrogen to the SLS Core Stage Forward Skirt. The center’s Engineering Directorate and the Ground Systems Development and Operations Program are overseeing processing and testing of the umbilicals.

Cranes and rigging are being used to lift up the Core Stage Forward Skirt Umbilical (CSFSU) for installation on the mobile launcher tower at NASA's Kennedy Space Center in Florida. The mobile launcher tower will be equipped with a number of lines, called umbilicals that will connect to the Space Launch System (SLS) rocket and Orion spacecraft for Exploration Mission-1 (EM-1). The CSFSU will be located at about the 180-foot level on the tower, above the liquid oxygen tank.

Inside the Booster Fabrication Facility (BFF) at NASA’s Kennedy Space Center in Florida, members of the news media view a forward skirt that will be used on a solid rocket booster for NASA’s Space Launch System (SLS) rocket. Orbital ATK is a contractor for NASA’s Marshall Space Flight Center in Alabama, and operates the BFF to prepare aft booster segments and hardware for the SLS solid rocket boosters. Rick Serfozo, Orbital ATK Florida site director, talks to the media. The SLS rocket and Orion spacecraft will launch on Exploration Mission-1 in 2018. The Ground Systems Development and Operations Program is preparing the infrastructure to process and launch spacecraft for deep-space missions and the journey to Mars.
