Seen here is a close-up view of the Orion stage adapter (OSA) structural test article atop the Space Launch System (SLS) rocket inside the Vehicle Assembly Building (VAB) at NASA’s Kennedy Space Center in Florida on Aug. 12, 2021. The test article, representing the mass and weight of the actual flight hardware, is being used for various tests inside the VAB ahead of OSA stacking operations. The first in an increasingly complex set of missions, Artemis I will test SLS and the Orion spacecraft as an integrated system prior to crewed flights to the Moon. Through Artemis, NASA will send the first woman and the first person of color to the lunar surface, as well as establish a sustainable presence on and around the Moon.

Inside NASA’s iconic Vehicle Assembly Building at Kennedy Space Center in Florida, teams from Exploration Ground Systems and contractor Jacobs mate the Orion Stage Adapter (OSA) to the Interim Cryogenic Propulsion Stage (ICPS) on top of the Space Launch System (SLS) on Oct. 9, 2021. The addition of the OSA marks the last piece of SLS rocket hardware to be added before crews soon add the Orion spacecraft and its launch abort system on top of the OSA. The ring-shaped OSA is filled with 10 shoebox-sized CubeSats that will deploy when the ICPS separates from Orion on its way to the Moon during Artemis I, which will be the first integrated flight test of the SLS and Orion spacecraft. In later missions, NASA will land the first woman and the first person of color on the surface of the Moon, paving the way for a long-term lunar presence and serving as a steppingstone on the way to Mars.

Despite their small size, they enable science and technology experiments that may enhance our understanding of the deep space environment, expand our knowledge of the Moon, and demonstrate new technologies that could be used on future missions.

The LunIR undergoes inspection prior to being loaded in the Space Launch System (SLS) rocket’s Orion stage adapter for the Artemis I mission on July 14 at NASA’s Kennedy Space Center in Florida. During lunar orbit, the satellite will use an infrared sensor to map the Moon’s surface and search for potential landing sites and critical resources for future missions to Mars and beyond.

Teams prepare the Lunar IceCube before its installation in the Space Launch System rocket Orion stage adapter at NASA’s Kennedy Space Center in Florida. This small satellite will be deployed from the rocket and will orbit the Moon for six months and search for water and ice with an infrared spectrometer.

Technicians at NASA’s Kennedy Space Center in Florida complete routine inspections the Artemis II Orion stage adapter on Wednesday, Aug. 20, 2025, to the spaceport’s Multi-Payload Processing Facility to undergo CubeSat integration following its arrival from the agency’s Marshall Flight Center in Huntsville, Alabama. NASA Marshall built the Orion stage adapter which connects to the SLS (Space Launch System) rocket’s interim cryogenic propulsion stage to the Orion spacecraft and protects Orion from flammable gases generated during launch. The Artemis II test flight will take four astronauts around the Moon and return them back home in early 2026.

Fueling and servicing checks on the Orion spacecraft for the Artemis I mission are completed inside Kennedy Space Center’s Multi-Payload Processing Facility on July 8, 2021. The capsule will be transported to the Florida spaceport’s Launch Abort System Facility, where teams with Exploration Ground Systems and contractor Jacobs will work to add parts of the launch abort system onto the spacecraft. Launching later this year, Artemis I will be a test of the Orion spacecraft and SLS rocket as an integrated system ahead of crewed flights to the Moon.

Small satellites, called CubeSats, are shown secured inside NASA’s Orion stage adapter at NASA’s Kennedy Space Center in Florida on Aug. 5, 2021. Technicians from Exploration Ground Systems and Jacobs teams are working with developers of the shoebox-sized secondary payloads as they undergo final processing. The ring-shaped stage adapter will be connected to the Space Launch System’s Interim Cryogenic Propulsion Stage, and the Orion spacecraft will be secured on top. The CubeSats will conduct a variety of science experiments and technology demonstrations that will expand our knowledge of the lunar surface during the Artemis I mission.

Tests are underway in High Bay 3 inside the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida on Aug. 13, 2021, using the Orion stage adapter structural test article and the Mass Simulator for Orion. Stacked atop the Space Launch System (SLS) rocket, these test articles represent the mass and weight of the actual Orion stage adapter and Orion spacecraft. Launching in 2021, Artemis I will be an uncrewed test of the Orion spacecraft and SLS rocket as an integrated system ahead of crewed flights to the Moon. Under Artemis, NASA aims to land the first woman and first person of color on the Moon and establish sustainable lunar exploration.
