NASA has overhauled its Artemis program, postponing the first human moon landing until the Artemis IV mission in early 2028. The changes, announced by Administrator Jared Isaacman on February 27, 2026, aim to increase launch frequency and reduce risks after repeated delays with the Space Launch System rocket. An additional test flight, now Artemis III, will focus on low-Earth orbit rendezvous with commercial lunar landers.
On February 27, 2026, NASA Administrator Jared Isaacman held a press conference to outline significant revisions to the Artemis program, driven by ongoing delays and safety concerns. The Space Launch System (SLS) rocket has faced multiple setbacks, including a hydrogen and helium fuel leak during its first wet dress rehearsal for Artemis II, followed by helium flow issues in the second test that required further repairs. As a result, Artemis II, a crewed lunar flyby mission, is now scheduled no earlier than April 1, 2026.
Previously, Artemis III was set to achieve the first human moon landing since 1972, but NASA has shifted that goal to Artemis IV in early 2028. The revised Artemis III, targeted for mid-2027, will launch into low-Earth orbit for tests, including rendezvous with commercial lunar landers from SpaceX (Starship) and/or Blue Origin (Blue Moon), and evaluations of a new spacesuit from Axiom Space. These adjustments address warnings from NASA's Aerospace Safety Advisory Panel that the original plan posed excessive risks due to the large gap between Artemis II and a direct lunar landing.
Isaacman emphasized the need for a higher launch cadence, stating, "Launching a rocket as complex as the SLS every three years is not a path to success." He advocated standardizing the SLS configuration, canceling the Exploration Upper Stage and Block 1B upgrade, and aiming for missions every 10 months to build skills and reliability, similar to the Apollo program's preparatory flights. A senior NASA official noted that past programs like Mercury, Gemini, and Apollo maintained launches every three months on average.
The changes have support from key partners. Boeing's Defense, Space & Security president and CEO, Steve Parker, said, "As NASA lays out an accelerated launch schedule, our workforce and supply chain are prepared to meet the increased production needs." Congress and commercial partners have been briefed and are aligned with the plan, amid concerns over competition from China's space program. NASA intends to continue using SLS until commercial alternatives emerge, potentially by Artemis V in late 2028 or 2029 if delays occur.
