Nasa has revealed new details about how long astronauts will live and work on the Moon during its first crewed lunar landing in over five decades, marking a major step forward in the agency’s Artemis programme.
The mission, known as Artemis IV, will see four astronauts travel to lunar orbit, with two of them descending to the Moon’s south polar region, an area of intense scientific interest due to the presence of water ice deposits.
The mission will be humanity’s first return to the lunar surface since Apollo 17 in 1972.
WHAT IS THE ARTEMIS-IV MISSION?
According to Nasa’s updated architecture, Artemis IV will last approximately 21 days from launch to return. During this time, the two astronauts assigned to the surface mission will be living and conducting experiments on the Moon.
Artemis-IV mission is a significant upgrade over the Apollo missions, where astronauts typically spent just a few days on the lunar surface.
The announcement builds on recent changes to the Artemis roadmap. The agency confirmed that it is standardising configurations for the Space Launch System (SLS) rocket to improve efficiency and reliability across missions.
Nasa has also added an additional mission to the schedule in 2027 and plans to conduct at least one crewed lunar landing every year thereafter.
Under this revised plan, Artemis III, now targeted for 2027, will not immediately attempt a lunar landing. Instead, it will focus on testing integrated systems and operational capabilities in Earth orbit, ensuring all components function seamlessly before committing astronauts to the surface during Artemis IV.
Nasa officials say this phased approach is designed to reduce risks while enabling more sustainable and frequent missions in the long term.
Looking beyond Artemis V, the agency announced that it plans to rely on commercially procured and reusable hardware increasingly.
HOW LONG WILL ASTRONAUTS LIVE ON THE MOON?
Once the two astronauts on Artemis-IV land on the surface of the Moon, they will spend about a week exploring the rugged lunar terrain.
The extended surface stay of nearly a week signals Nasa’s transition from short exploratory visits to longer, more productive missions, laying the groundwork for a permanent human foothold beyond Earth.
This shift aims to lower costs and increase mission cadence, with an initial goal of conducting crewed lunar landings every six months. As technologies mature, Nasa expects this frequency to rise further.
In parallel, Nasa is rethinking its long-term lunar infrastructure strategy. The agency plans to pause development of the Gateway space station in its current form and instead prioritise systems that directly support sustained human presence on the Moon.
This includes habitats, power systems and surface mobility solutions that can enable astronauts to live and work on the lunar surface for extended durations.
