Artemis 3 Lunar Landing Site Coordinates: The Final Target for Humanity's Return

Key Questions & Expert Answers (Updated: 2026-03-05)

What are the exact coordinates for the Artemis 3 landing site?

NASA does not use a single point for lunar landings due to orbital mechanics and terrain hazards. Instead, they use a "landing ellipse." As of March 2026, the leading primary target is the Malapert Massif region, with the primary landing ellipse centered roughly at 85.99° S, 2.93° E. Secondary backup regions include the Peak Near Shackleton (approx. 89.78° S, 129.20° E).

Has NASA finalized the Artemis 3 landing date?

Following hardware evaluations of the SpaceX Starship Human Landing System (HLS) and Axiom Space's extravehicular mobility units, NASA is officially targeting a launch window in September 2026. The exact day relies on a complex algorithm of Earth-Moon alignment, determining which specific set of coordinates will be illuminated during the landing phase.

Why is the Lunar South Pole the target?

The coordinates chosen lie directly adjacent to Permanently Shadowed Regions (PSRs). Because the Sun hovers near the horizon at the lunar poles, deep craters never receive sunlight. These freezing traps hold billions of years of volatile compounds, notably water ice, which is the foundational resource for future lunar propellant manufacturing and life support.

Can the SpaceX Starship land on such rugged terrain?

Landing at the South Pole is notoriously difficult due to extreme craters and lighting illusions. The Starship HLS utilizes advanced Terrain Relative Navigation (TRN) to map the ground in real-time, allowing it to divert within a 100-meter accuracy radius to avoid boulders and slopes greater than 10 degrees at the target coordinates.

1. The Return to the Moon: Context for 2026

More than half a century after Apollo 17 departed the Taurus-Littrow valley, humanity is on the precipice of a return. But unlike the equatorial landing sites of the Apollo era, the Artemis 3 mission is venturing into the unknown: the Lunar South Pole. As of March 5, 2026, mission planners at NASA's Johnson Space Center have transitioned from long-term theoretical planning into locked-in mission simulations.

Selecting the exact Artemis 3 lunar landing site coordinates is arguably the most complex orbital puzzle NASA has ever solved. The agency originally announced 13 candidate regions in 2022. Fast forward to today, the constraints of the SpaceX Starship HLS (Human Landing System) fuel margins, Axiom spacesuit mobility data, and precise orbital lighting conditions have forced a down-selection to a highly concentrated set of coordinates.

2. The Final Candidates: Coordinate Breakdown

Because the launch window dynamically shifts the lighting at the lunar South Pole, NASA cannot pick just one coordinate. They must maintain a primary target and several backups. Below are the finalized regions and their approximate coordinate centers actively being simulated as of early 2026.

The Malapert Massif has emerged as the frontrunner. Located on the Earth-facing side of the Moon, it mitigates the need for a complex network of relay satellites. The exact landing ellipse is roughly a 2-kilometer zone where the Starship TRN (Terrain Relative Navigation) system will independently select the safest 20-meter patch of regolith.

3. Lighting Constraints and Orbital Mechanics

At the coordinates associated with the Artemis 3 mission, the Sun is never more than a few degrees above the horizon. This creates spectacular, elongated shadows that are both a blessing and a curse.

The Curse: Long shadows cast by crater rims can hide massive boulders or sheer drops. The optical navigation sensors on the Starship HLS have to be programmed to understand that a shadow does not necessarily mean a crater. Furthermore, the launch must be timed perfectly so that the chosen landing coordinates are bathed in sunlight for the entire 6.5-day duration of the surface mission. A sudden drop into a 14-day lunar night would be catastrophic for thermal management.

The Blessing: These exact grazing lighting conditions are what create the Permanently Shadowed Regions (PSRs). By landing on an illuminated ridge (like the Peak Near Shackleton at 89.78° S), astronauts have the solar power necessary to survive, while being just a short walk away from a pitch-black crater that hasn't seen sunlight in two billion years.

4. Geological Significance of the South Pole

Why obsess over these specific coordinates? The South Pole sits on the rim of the South Pole-Aitken (SPA) basin, one of the largest and oldest impact craters in the solar system. The rocks and regolith at coordinates like 85.99° S, 2.93° E contain excavated mantle material from deep within the Moon.

However, the crown jewel is water ice. Lunar Reconnaissance Orbiter (LRO) data confirms high hydrogen signatures in these regions. The Artemis 3 crew will use specialized tools to core into the regolith within the PSRs to extract ice. If this ice is abundant and accessible, it proves the viability of "In-Situ Resource Utilization" (ISRU)—meaning future missions can split the water into hydrogen and oxygen to fuel rockets for Mars.

5. Astronaut Traverse Planning and AxEMU Limitations

Landing at the correct coordinates is only half the battle. Once there, the astronauts must walk. As of March 2026, Axiom Space has finalized the capabilities of the AxEMU (Axiom Extravehicular Mobility Unit) spacesuits.

The traverse routes (where astronauts will walk) are strictly bound by the landing coordinates. Because the HLS elevator drops them onto the surface, they have a maximum safe walking radius of approximately 2 kilometers from the lander. At the Connecting Ridge (89.45° S), mission planners have already mapped out specific 1.5-kilometer round-trip paths that keep the astronauts within line-of-sight of the HLS communications relay while dipping into the edge of a shadowed crater.

These routes have been modeled down to the centimeter using the latest photogrammetry, ensuring astronauts don't accidentally wander into terrain steeper than 15 degrees, which could cause them to lose their footing in the 1/6th gravity environment.

6. Future Outlook: The Final Countdown

As we push through the spring of 2026, the focus has shifted entirely to launch readiness. The specific Artemis 3 lunar landing site coordinates will be permanently locked into the flight computers exactly 60 days before the September 2026 launch window opens.

In the coming months, expect NASA to announce the final orbital parameters for the Orion spacecraft's rendezvous with the Starship HLS in Near-Rectilinear Halo Orbit (NRHO). Humanity is returning to the Moon, and this time, we have the exact map to the water.
