Artemis III slips three months, threatening 2028 moon landing

NASA's Artemis III is about three months behind schedule and could launch in summer 2027, administrator Jared Isaacman said. If the delay persists, the agency may get only one chance to land astronauts on the moon in 2028 instead of two.

• Artemis III could launch in summer 2027, the "best-case scenario"
• Crew will rehearse docking Orion with SpaceX and Blue Origin landers in Earth orbit
• Continued delays could leave just one 2028 landing attempt
• NASA is working directly with suppliers over delayed valves and rocket steering parts
