NASA has begun rolling back its Artemis II Moon rocket from Launch Complex 39B at Kennedy Space Center to address technical issues, marking a significant step in the mission’s preparation timeline. The Space Launch System rocket and Orion spacecraft are scheduled to start the slow journey to the Vehicle Assembly Building at around 7:30 p.m. IST on February 25. The 6.4-kilometre transport aboard NASA’s crawler-transporter is expected to take up to 12 hours as teams monitor wind and temperature conditions to ensure safe movement
The rollback follows the detection of a helium flow issue during earlier operations, prompting engineers to conduct repairs in a controlled environment. NASA had originally targeted a March 6 launch, but officials now indicate the mission will likely shift to April 2026.
Artemis II represents NASA’s first crewed mission under the Artemis program and will send four astronauts on a lunar flyby, laying the groundwork for future Moon landings. The SLS rocket is currently the most powerful launch vehicle developed by NASA, designed to carry heavy payloads beyond Earth orbit.
Inside the Vehicle Assembly Building, technicians will install work platforms around the affected section to address the helium system. Engineers will also replace batteries in the flight termination system, a critical safety mechanism that can destroy the rocket if it deviates from its path. Additional upper-stage batteries will be replaced as part of routine mission assurance and retesting.
Space industry analysts note that rollbacks are common in complex human spaceflight programs. Experts say identifying technical issues early reduces long-term risk and helps protect crew safety. The Artemis program’s emphasis on reliability reflects lessons learned from previous lunar and deep-space missions, where minor system anomalies could lead to major delays if not addressed promptly.
The Artemis II delay highlights the complexity of next-generation space missions and the growing collaboration between government agencies and private aerospace companies. The mission is closely watched by commercial partners, satellite providers, and international space agencies, as its success could accelerate lunar infrastructure, deep-space research, and future commercial opportunities.
A timeline shift may affect downstream Artemis missions, but it reinforces NASA’s safety-first approach, which remains central to human spaceflight.
While the rollback may push Artemis II’s launch window, the move underscores NASA’s commitment to system reliability before sending astronauts around the Moon. As repairs begin and retesting progresses, the mission remains a crucial milestone in humanity’s return to lunar exploration.
