Key Questions & Expert Answers (Updated: 2026-03-09)
Where exactly will Artemis III land?
NASA has selected a high-elevation plateau on Malapert Massif, located approximately 122 kilometers from the exact geographic Lunar South Pole. This peak rises nearly 5,000 meters above its surrounding terrain, providing unparalleled access to both sunlight and ancient lunar geology.
Why was this specific site chosen right now?
The decision came down to ultra-precise radar altimetry data processed over the last six months. Malapert Massif satisfied three uncompromisable constraints: a surface slope of less than 8 degrees (required by the SpaceX Starship Human Landing System to avoid tipping), over 60% continuous sunlight during the 6.5-day surface mission, and direct line-of-sight to Earth's Deep Space Network.
Is the September 2026 launch date still on track?
Yes. With the landing site formally locked in today, the mission profile is officially "frozen." This allows trajectory engineers to finalize the orbital insertion burns and enables the crew to begin spacewalk rehearsals in Houston on physical mock-ups identical to the Malapert topography.
What will the astronauts do at the Malapert landing site?
Equipped with Axiom Extravehicular Mobility Units (AxEMU), the crew will conduct up to four moonwalks. Their primary objective is a 1.5-kilometer traverse from the sunlit landing pad into the edge of a nearby Permanently Shadowed Region (PSR) to extract primordial water ice core samples.
The March 2026 Announcement: History in the Making
After nearly four years of intense debate, high-resolution topographical scanning, and rigorous engineering reviews, the wait is over. On March 9, 2026, NASA's Planetary Science Division, in tight coordination with SpaceX and Axiom Space, declared Malapert Massif as the official, finalized destination for the Artemis III mission.
The selection marks a pivotal transition in the Artemis program. For years, the scientific community operated with a list of 13 potential south polar regions. While having options was necessary during the development of the SpaceX Starship Human Landing System (HLS) and the Axiom spacesuits, the time to commit had arrived. Launching in exactly six months requires a locked-in orbital trajectory, finalized fuel load calculations, and precisely timed communication relay windows.
"You cannot train for thirteen different mountains," noted a senior NASA flight director during the press briefing. "Today, we give our crew their mountain. Malapert Massif is where humans will take their next first steps on another world."
The Geography of Malapert Massif
Malapert Massif is an ancient, towering structure dating back to the pre-Nectarian period of lunar history—over 4 billion years ago. Located on the Earth-facing side of the moon, just adjacent to the South Pole, it is a relic of the massive impact that created the South Pole-Aitken Basin.
The finalized landing ellipse is situated on a relatively flat plateau near the massif's summit. This specific micro-region was chosen for its distinct juxtaposition of extremes. The peak itself is bathed in sunlight for a large portion of the lunar year, creating a relatively benign thermal environment for the lander's solar arrays. Yet, just a few kilometers away, the terrain dips steeply into craters that have not seen sunlight in billions of years.
These Permanently Shadowed Regions (PSRs) function as cosmic deep freezes. Scientists expect to find water ice, volatile organic compounds, and potentially clues to the early solar system trapped within the regolith here. The Malapert site offers the safest, shortest walking distance for astronauts from a sunlit "safe zone" to the edge of an ice-rich PSR.
Engineering the Descent: Starship HLS and Axiom Constraints
The finalization of the Artemis III lunar landing site wasn't driven solely by scientific desire; it was heavily dictated by cold, hard engineering constraints. The architecture of Artemis III relies on two highly specific pieces of commercial hardware: the SpaceX Starship HLS and the Axiom AxEMU spacesuit.
The Starship HLS Factor: Unlike the Apollo Lunar Module, which was squat and lightweight, the Starship HLS is a massive silo, towering 50 meters above the lunar surface. Landing a vehicle with such a high center of gravity requires an exceptionally flat surface. LRO (Lunar Reconnaissance Orbiter) stereoscopic imaging confirmed that the Malapert plateau contains an area of roughly 100 square meters where the surface slope does not exceed 6 degrees. Anything steeper, and the autonomous landing software would abort the descent.
Axiom Spacesuit Thermal Limits: The AxEMU suits are marvels of modern engineering, boasting advanced joint mobility and life support. However, operating in the South Pole means transitioning from the blazing 120°C (250°F) sunlight of the peak down to the staggering -200°C (-330°F) cold of the shadowed craters. The route plotted at Malapert allows the astronauts to ease into these thermal gradients safely, remaining within the suit's heating and cooling capacities during their maximum 6-hour excursions.
Why Candidate Sites Like Shackleton Were Eliminated
To understand why Malapert Massif won, it is helpful to understand why the other prominent candidate regions—such as the Peak Near Shackleton, Faustini Rim, and de Gerlache—were ultimately passed over for the prime slot.
| Candidate Site | Primary Drawback that Led to Elimination | Current Status |
|---|---|---|
| Peak Near Shackleton | Terrain near the lip proved too rugged for the wide landing stance of the Starship HLS. High risk of landing pad damage. | Designated as Primary Backup |
| de Gerlache Rim | Earth line-of-sight is periodically interrupted by local topography, requiring an orbital relay satellite which Artemis III lacks. | Eliminated for Art III |
| Nobile Rim 1 & 2 | Insufficient continuous solar illumination during the specific 6.5-day window planned for late September 2026. | Reserved for Artemis IV/V |
| Malapert Massif | None. Meets all slope, comms, and lighting constraints perfectly. | Finalized Prime Site |
Shackleton Crater has long been the darling of the lunar scientific community due to its massive, deep shadow. However, the exact lip of Shackleton lacks a wide enough flat zone to provide a 99.9% safety margin for Starship. As a result, Shackleton has been downgraded to the backup site, to be used only if trajectory anomalies force a last-minute orbital deviation.
Future Outlook: The Road to September 2026
With the Artemis III lunar landing site finalized as of today, March 9, 2026, the mission shifts from planning into execution. Over the next six months, the cadence of operations will accelerate dramatically.
In Boca Chica, Texas, SpaceX is preparing for the final uncrewed Starship LEO (Low Earth Orbit) propellant transfer tests—a critical prerequisite before sending the HLS to lunar orbit. Meanwhile, at the Johnson Space Center in Houston, the rock yards have been bulldozed and reshaped. Using virtual reality headsets integrated with physical rocks, the Artemis III crew is now practicing the exact walking paths, rock sampling techniques, and tool deployments they will execute at Malapert Massif.
The finalization of this site is more than a technical milestone; it is a psychological one. Humanity finally has a specific address for its return to the Moon. When we look up at the lunar disk tonight, we no longer look at a general region. We can point our telescopes toward the southern edge, look at the towering shadow of Malapert Massif, and know that very soon, human footprints will disturb its ancient dust.
Frequently Asked Questions (FAQ)
When is Artemis III scheduled to land at the finalized site?
As of current schedules in March 2026, the Artemis III mission is targeted for a late September 2026 launch, with the landing occurring roughly a week after launch following orbital phasing.
Can we see Malapert Massif from Earth?
Yes, but it is challenging. Because it sits on the Earth-facing side near the southern limb, it is technically visible. However, due to its location at the edge of the visible lunar disk, it requires a good telescope and favorable lunar libration (the slight "wobble" of the Moon) to be seen clearly.
Why didn't they choose the Apollo landing sites at the equator?
The Apollo missions landed near the lunar equator because it was trajectory-efficient and well-lit. However, the equator is bone-dry. Artemis aims to establish a sustainable human presence, which requires local resources like water ice. Water ice only exists in the Permanently Shadowed Regions at the lunar poles.
Will there be a lunar rover on Artemis III?
No. Artemis III will be a walking-only mission. The Lunar Terrain Vehicle (LTV), an unpressurized rover, is currently slated to be delivered to the lunar surface in time for the Artemis V mission later in the decade.
What happens if the landing is aborted?
If the Starship HLS autonomous navigation detects boulders or extreme slopes at the Malapert Massif site during final descent, it has the thrust capability to abort, hover, and either divert to a secondary flat zone nearby or return to lunar orbit to rendezvous with the Orion spacecraft.
