Here Is What NASA's Artemis III Mission Will Do

NASA’s Artemis III mission, set for launch in 2027, will focus on testing two lunar landers in Earth orbit rather than attempting a Moon landing. The mission will involve four astronauts aboard an Orion capsule launched by an SLS rocket, mirroring the Artemis II flight earlier this year. Blue Origin’s Blue Moon lander will be sent into orbit via a New Glenn rocket, docking with Orion for two days of tests, while SpaceX’s Starship will also dock with Orion for one day of evaluations without crew entry. The mission spans approximately two weeks, including multiple rocket launches and docking procedures, marking the most complex single mission in NASA’s history. Neither lander exists yet, and Starship has never flown into orbit, while Blue Origin’s New Glenn suffered a launchpad explosion in 2024, delaying its readiness. These risks underscore why Artemis III prioritizes testing over lunar landings, with Artemis IV targeting a 2028 Moon landing if all goes as planned. Originally intended as the first crewed Moon landing since 1972, Artemis III was redesigned in February 2024 to focus on orbital demonstrations. The mission’s success is critical for NASA’s long-term goal of establishing a lunar base, requiring astronauts to relearn landing procedures. Delays in lander development and launch vehicle readiness could push back future missions, but NASA insists on thorough testing before attempting lunar landings. The mission’s complexity involves three separate rocket systems—SLS, New Glenn, and Starship—each requiring coordination in orbit. Astronauts will practice docking and undocking with both landers but will not board Starship, ensuring safety while validating critical systems. If Artemis III succeeds, it will pave the way for Artemis IV’s lunar surface missions, though challenges remain in integrating untested hardware and meeting tight timelines.
