A NASA drone photo offers a bird’s-eye view of the B-2 Test Stand at NASA’s Stennis Space Center with the first flight core stage for NASA’s new Space Launch System (SLS) installed for Green Run testing. The SLS core stage is undergoing a series of tests on its integrated systems prior to its use on the Artemis I mission. NASA is building SLS to return humans, including the first woman, to the Moon as part of the Artemis program and to prepare for eventual missions to Mars. The Green Run series at Stennis culminates with a hot fire of the core stage’s four RS-25 engines, just as during an actual launch.

Engineers and technicians drive crawler-transporter 2 along the crawlerway toward the Vehicle Assembly Building (VAB) at NASA’s Kennedy Space Center in Florida on June 1, 2022. The crawler will go inside the VAB, where it will slide under the Artemis I Space Launch System with the Orion spacecraft atop on the mobile launcher and carry it to Launch Complex 39B for a wet dress rehearsal test ahead of the Artemis I launch. Artemis I will be the first integrated 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.

A member of the Artemis launch team participates in the second wet dress rehearsal for the Artemis II mission on Thursday, Feb. 19, 2026, inside Firing Room 2 at the Rocco A. Petrone Launch Control Center at NASA’s Kennedy Space Center in Florida. The wet dress rehearsal allows the Artemis II launch team to run through operations to load propellant, conduct a full launch countdown, demonstrate the ability to recycle the countdown clock, and drain the tanks to practice timelines and procedures for launch. The Artemis II test flight will take Commander Reid Wiseman, Pilot Victor Glover, and Mission Specialist Christina Koch from NASA, and Mission Specialist Jeremy Hansen from the CSA (Canadian Space Agency), around the Moon and back to Earth from Launch Complex 39B at NASA Kennedy.

A flatbed truck with the shipping container carrying the heat shield for Orion’s Artemis 2 mission, NASA’s first crewed mission, moves into the Neil Armstrong Operations and Checkout Building high bay at the agency’s Kennedy Space Center in Florida on July 9, 2019. The heat shield, measuring roughly 16 feet in diameter, will protect astronauts upon re-entry on the second mission of Artemis. The heat shield arrived from Lockheed Martin’s manufacturing facility near Denver aboard NASA’s Super Guppy Aircraft. The heat shield is a base titanium truss structure. Over the next several months, technicians will apply Avcoat, an ablative material that will provide the thermal protection. Artemis 2 will confirm all of the spacecraft’s systems operate as designed in the actual environment of deep space with astronauts aboard.

A close-up view of the treads on crawler-transporter 2 (CT-2) as the behemoth vehicle moves along the crawlerway at NASA’s Kennedy Space Center in Florida on Jan. 22, 2021. Teams are working to ensure the crawlerway, the path the CT-2, mobile launcher, and Space Launch System rocket with Orion atop will take from the Vehicle Assembly Building to Launch Complex 39B, is strong enough to withstand the weight and provide stability for the Artemis I mission. CT-2 carrying mobile launcher platform 1, used during the shuttle program, was driven back and forth on the crawlerway with several cement blocks, each weighing about 40,000 pounds to strengthen the crawlerway for launch. Artemis I will be the first in a series of increasingly complex missions to the Moon. Under the Artemis program, NASA aims to land the first woman and the next man on the Moon in 2024 and establish sustainable lunar exploration by the end of the decade.
