NASA plans to transport the SLS rocket from the Artemis II mission back to the launch pad on March 20, maintaining the schedule for the crewed flight in April. The agency completed necessary work in the vehicle assembly building at Centro Espacial Kennedy, at Flórida, after identifying and replacing a flight termination system wiring harness in the rocket’s core stage. Essa stage represents the second movement of the vehicle to Launch Complex-39B since January, when the first test trip took place. The launch remains scheduled for the beginning of April, with the first opportunity on April 1st, with no impact on the main calendar.
The operation involves the crawler transporter, which will move the complete stack of the SLS and the Orion spacecraft over approximately 6.4 kilometers at a speed of approximately 1.6 km/h. The process should last up to 12 hours, depending on local weather conditions. NASA’s Equipes monitor all systems to ensure integrity en route.
Final preparations in the assembly building
Technicians completed closing activities and checks after correcting the wiring harness. The repair was completed faster than initially anticipated. Isso made it possible to evaluate the possibility of bringing forward the displacement, but the date of March 20 was maintained to ensure all checks.
Component replacement occurred without additional complications. Engenheiros confirmed the functionality of the flight termination system. Teams continue with final inspections before moving.

The SLS and Orion will be transported vertically on the mobile launcher. The route follows the route established at the launch complex. NASA will broadcast the event live for public viewing.
Weather conditions at Flórida will be continuously evaluated. Qualquer adjustment will occur based on local forecasts. The objective is to position the vehicle for final tests before launch.
Mission context Artemis II
Artemis II will be the first manned flight of the Artemis program, sending four astronauts on a trajectory around Lua. The mission lasts about ten days and tests life support systems in a deep space environment. The crew includes NASA astronauts Reid Wiseman (commander), Victor Glover (pilot), Christina Koch (mission specialist), and the Agência Espacial Canadense Jeremy Hansen astronaut.
The flight represents the return of humans to lunar space after more than 50 years. The Orion spacecraft will perform translunar injection maneuvers and use the Lua’s gravity for a free return path. Sistemas of communication, navigation and radiation protection will be validated during the journey.
Previous tests and adjustments made
Problems identified in wet suit trials led to the vehicle’s return to the assembly building in February. An issue with the helium flow in the upper stage was resolved during the period in the VAB. Esses adjustments ensure reliability for manned flight.
The first rollout took place in January, followed by tests on the platform. The second move prepares the SLS for final countdown operations. Equipes perform integrated checks between rocket, spacecraft and ground infrastructure.
Next steps towards launch
Upon arrival at the platform, NASA will conduct additional integration and fueling tests. The flight readiness review confirmed progress toward the launch window. Additional Oportunidades exist in April if adjustments are necessary.
The Artemis program advances with a focus on sustainable missions to Lua. The Artemis II lays foundations for subsequent manned landings and long-term exploration.
