On 27 February 2026, NASA announced an update to the Artemis programme architecture and the addition of an extra mission in 2027. The agency said the plan includes standardising the configuration of the SLS rocket and the Orion spacecraft for upcoming flights. NASA said Artemis III is scheduled for 2027 and will include testing of systems and procedures in low Earth orbit ahead of a lunar landing under Artemis IV in 2028.
NASA indicated that Artemis III is to include rendezvous and docking manoeuvres with one or two commercial landers being developed by SpaceX and Blue Origin. The agency announced integrated tests of systems including life support, communications and propulsion using the combined vehicles. NASA also said it plans to test xEVA spacesuits as part of the updated Artemis III mission. NASA said detailed objectives for the revised Artemis III will be presented later following reviews with industry partners.
NASA said that on 25 February 2026 the SLS rocket and Orion for Artemis II were rolled back from the launch pad to the Vehicle Assembly Building to address a helium flow issue to the upper stage and to carry out additional technical work. NASA said the updated plan aims for at least one lunar landing in each subsequent year after the first landing under the new mission sequence.
