NASA’s Space Launch System (SLS) rocket with the Orion spacecraft aboard is seen atop the mobile launcher at Launch 39B at NASA’s Kennedy Space Center in Florida. Artemis I mission is the first integrated test of the agency’s deep space exploration systems: the Space Launch System rocket, Orion spacecraft, and supporting ground systems. The mission is the first in a series of increasingly complex missions to the Moon. Launch of the uncrewed flight test is targeted for no earlier than Aug. 29 at 8:33 a.m. ET. With Artemis missions, NASA will land the first woman and first person of color on the Moon, using innovative technologies to explore more of the lunar surface than ever before.

NASA Administrator Bill Nelson (second from right) meets with members of the “red crew” after the launch of Artemis I at NASA’s Kennedy Space Center in Florida on Nov. 16, 2022. Members of the red crew include Jacobs/TOSC ERC employees Billy Cairns, cryogenic engineering technician (left); Chad Garrett (second from left), safety engineer; and Trent Annis (right), cryogenic engineering technician. The team of technicians are part of the personnel specially trained to conduct operations at the launch pad during cryogenic loading operations at the launch pad. Prior to the launch of Artemis I, the red crew entered the zero deck, or base, of the mobile launcher and tightened several bolts to troubleshoot a valve used to replenish the core stage with liquid hydrogen which showed a leak with readings above limits. NASA has historically sent teams to the pad to conduct inspections during active launch operations as needed. Artemis I launch successfully at 1:47 a.m. EST on Nov. 16, from Kennedy’s Launch Pad 39B.

These images and videos show team members moving the first core stage that will help launch the first crewed flight of NASA’s SLS (Space Launch System) rocket for the agency’s Artemis II mission. The move marked the first time a fully assembled Moon rocket stage for a crewed mission has rolled out from NASA’s Michoud Assembly Facility in New Orleans since the Apollo Program, The core stage was moved onto the agency’s Pegasus barge, where it will be ferried to NASA’s Kennedy Space Center in Florida. The core stage for the SLS mega rocket is the largest stage NASA has ever produced. At 212 feet tall, the stage consists of five major elements, including two huge propellant tanks that collectively hold more than 733,000 gallons of super chilled liquid propellant to feed four RS-25 engines at its base. During launch and flight, the stage will operate for just over eight minutes, producing more than 2 million pounds of thrust to help send a crew of four astronauts inside NASA’s Orion spacecraft onward to the Moon. NASA is working to land the first woman, first person of color, and its first international partner astronaut on the Moon under Artemis. SLS is part of NASA’s backbone for deep space exploration, along with the Orion spacecraft and Gateway in orbit around the Moon and commercial human landing systems, next-generation space, next-generational spacesuits, and rovers on the lunar surface. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single launch.

These images and videos show Reid Wiseman and Jeremy Hansen, members of the Artemis II crew, viewing the core stage of NASA’s SLS (Space Launch System) rocket at NASA’s Michoud Assembly Facility on Tuesday, July 16, 2024. The Artemis II astronauts met with team members at Michoud and the crew of NASA’s Pegasus barge prior to their departure to deliver the core stage to the Space Coast. NASA astronaut and pilot of the Artemis II mission Victor Glover met the crew July 15. Wiseman and Hansen visited the barge July 16, shortly before the flight hardware was loaded onto it.

These photos show how technicians at NASA’s Marshall Space Flight Center in Huntsville, Alabama, have applied the thermal protection system material to the launch vehicle stage adapter (LVSA) of NASA’s SLS (Space Launch System) rocket for Artemis III, which will land astronauts on the Moon to advance long-term lunar exploration and scientific discovery and inspire the Artemis Generation. The LVSA is a cone-shaped element that connects the mega rocket’s core stage to its interim cryogenic propulsion stage (ICPS), partially enclosing it and protecting its avionics and electrical systems from the extreme pressures, sounds, and temperatures during launch and flight. Teams at Marshall began applying the thermal protection system material in the spring of 2023. Unlike other parts of the SLS rocket, the thermal protection system material for the LVSA is applied entirely by hand using a spray gun. During application, the technicians use a thin measuring rod to gauge the proper thickness. Once the thermal protection system has cured, certain areas are sanded down to meet parameters. The entire process takes several months. The LVSA is fully manufactured at Marshall by NASA, lead contractor Teledyne Brown Engineering, and the Jacobs Space Group’s ESSCA contract. The LVSA for Artemis III is the last of its kind as future SLS rockets will transition to its next, more powerful Block 1B configuration beginning with Artemis IV.

The Space Launch System (SLS) program heralds the arrival of the SLS core stage with a symbolic “passing of the baton” to NASA’s Exploration Ground Systems (EGS) on April 28, 2021, at the agency’s Kennedy Space Center in Florida, marking the transition into final preparations for flight. Journeying from NASA’s Stennis Space Center in Mississippi aboard the Pegasus barge, the core stage arrived at the Florida spaceport on April 27. It is the final piece of Artemis hardware to arrive at Kennedy and will be offloaded and moved to the Vehicle Assembly Building, where it will be prepared for integration atop the mobile launcher with the completed stack of solid rocket boosters ahead of the Artemis I launch. The first in a series of increasingly complex missions, Artemis I will test SLS and Orion as an integrated system prior to crewed flights to the Moon.

These images show NASA employees attending an event August 14, 2025, at Marshall Space Flight Center in Huntsville, Alabama, to view the Orion stage adapter for Artemis II before it is transported to NASA’s Kennedy Space Center in Florida. Manufactured entirely at NASA Marshall, the adapter plays a crucial role in connecting the SLS (Space Launch System) rocket’s interim cryogenic propulsion stage to the Orion spacecraft. This adapter is the final piece of SLS hardware to be delivered to Kennedy Space Center in preparation for the Artemis II mission.
