Key Questions & Expert Answers (Updated: 2026-03-11)

What is the exact location of the new Artemis III landing site?

NASA has selected Malapert Massif (near the Lunar South Pole). It is a prominent, ancient mountain formation located roughly 122 degrees east and 85 degrees south. This site was chosen from an original list of 13 candidates due to its favorable illumination and relatively flat ridges.

Why did NASA wait until March 2026 to make the final announcement?

Landing a massive vehicle like the SpaceX Starship Human Landing System (HLS) requires hyper-specific lighting conditions and orbital alignments. By finalizing the decision six months prior to the September 2026 launch window, orbital dynamicists at NASA were able to lock in precise launch trajectories based on exact Earth-Moon-Sun geometry for Q3/Q4 2026.

Is the September 2026 launch date firmly locked?

While spaceflight is always subject to weather and last-minute technical delays, NASA Administrator Bill Nelson confirmed this morning that all major hardware—including the SLS Block 1 rocket, Orion spacecraft, and Axiom spacesuits—are in their final integration phases. The September 2026 window is considered highly viable.

1. The Final Countdown Begins

After years of analysis, debates, and shifting timelines, humanity’s return to the lunar surface has a definitive destination. In a highly anticipated press briefing from NASA Headquarters on March 11, 2026, the agency confirmed that the Artemis III mission will touch down at Malapert Massif. This announcement ends months of speculation and firmly sets the stage for the first crewed lunar landing since Apollo 17 in 1972.

Unlike the equatorial plains visited by the Apollo missions, the Artemis program targets the lunar South Pole—a region marked by extreme terrain, harsh lighting, but immeasurable scientific value. The decision comes exactly six months ahead of the targeted September 2026 launch, allowing flight controllers and the Artemis III crew to finalize their simulator training using high-resolution topological maps of the Malapert massif region.

2. Why Malapert Massif? The Science and Engineering

The journey to selecting Malapert Massif began in 2022 when NASA identified 13 candidate regions. Whittling that list down required balancing complex engineering constraints against maximum scientific yield.

The Illumination Advantage

At the lunar South Pole, the Sun hovers just above the horizon, creating impossibly long shadows and deep craters that have not seen sunlight in billions of years. Malapert Massif is a towering geological feature, meaning its peak receives near-continuous sunlight during the targeted landing window. This is critical for two reasons:

  • Thermal Regulation: The extreme cold of shaded lunar regions poses severe threats to spacecraft systems. Solar illumination helps maintain operational temperatures.
  • Power Generation: Although the Starship HLS utilizes significant internal battery reserves, surface operations require sustained solar power.

Direct-to-Earth Communication

Because the Moon is tidally locked, not all regions of the South Pole have a direct line of sight to Earth. Malapert Massif’s elevation and orientation provide uninterrupted radio-frequency communication with the Deep Space Network (DSN), a strict safety requirement for the first Artemis surface expedition.

Proximity to Permanently Shadowed Regions (PSRs)

The primary scientific objective of Artemis III is to sample lunar water ice. The landing zone on Malapert Massif is situated safely on a sunlit plateau but is within walking distance—roughly a 2-kilometer traverse—of permanently shadowed craters. Here, astronauts will deploy tools to extract cryogenic samples that could hold the key to sustaining long-term human presence on the Moon.

3. Hardware Readiness: Starship HLS and Axiom Spacesuits

Landing at the South Pole isn't just a geographic challenge; it is fundamentally an engineering one. The announcements today were paired with critical updates regarding the mission's hardware.

The SpaceX Starship HLS

SpaceX’s Starship Human Landing System is vastly larger than the Apollo Lunar Module. Landing a 50-meter-tall spacecraft on uneven terrain requires a site with a specific slope tolerance. High-resolution telemetry from the Lunar Reconnaissance Orbiter (LRO) confirmed a 100-meter radius "bullseye" on Malapert Massif with less than a 5-degree slope, well within Starship's landing leg tolerances.

Axiom Extravehicular Mobility Unit (AxEMU)

Axiom Space representatives confirmed today that the AxEMU suits have completed their final thermal vacuum chamber testing. Because the South Pole features extreme temperature gradients (stepping from a sunlit ridge at 130°F into a shadowed crater plunging to -300°F), the suits require advanced thermal management systems unparalleled in the history of spaceflight.

4. Geopolitical Context: The Lunar South Pole Race

The urgency of the March 2026 announcement is underscored by the broader geopolitical space race. China’s Chang'e lunar exploration program has been making rapid advancements, with its International Lunar Research Station (ILRS) initiative heavily targeting the lunar South Pole.

By formally claiming and charting the landing coordinates for Malapert Massif, NASA is enforcing the principles of the Artemis Accords. The Accords emphasize transparent exploration and the establishment of "safety zones" around active lunar operations. Setting down the Artemis III footprint first establishes a crucial precedent for international space law and resource utilization.

5. Frequently Asked Questions (FAQ)

When is the Artemis III mission launching?

As of the March 2026 update, Artemis III is scheduled for a launch window opening in September 2026. This reflects the revised timeline announced by NASA in early 2024 to allow for further hardware testing.

Who are the astronauts flying on Artemis III?

While the Artemis II crew (Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen) has been established for the orbital mission, NASA is expected to formally announce the Artemis III surface crew in the coming weeks following this site selection. It will include the first woman and first person of color to walk on the Moon.

What makes the Lunar South Pole so difficult to land on?

The terrain is highly rugged, heavily cratered, and shadowed. The low angle of the Sun creates long, deep shadows that can confuse optical landing sensors, making autonomous hazard avoidance incredibly difficult compared to the flat equatorial plains of the Apollo missions.

What is the backup landing site?

NASA has selected the Connecting Ridge as the official backup site. If launch delays alter the orbital alignment and lighting conditions for Malapert Massif, Connecting Ridge offers the next best combination of safety, communication, and scientific value.

How long will the astronauts stay on the lunar surface?

The Artemis III surface mission is scheduled to last approximately 6.5 days. During this time, the two astronauts on the surface will conduct up to four spacewalks (EVAs) while the other two remain in lunar orbit aboard the Orion spacecraft.

6. Future Outlook: Beyond Artemis III

The selection of Malapert Massif is merely the first anchor point in a much broader architecture. Data gathered from the Artemis III landing will directly inform the placement of the future Artemis Base Camp.

Looking ahead to Artemis IV (currently slated for 2028), the focus will shift to delivering modules to the Lunar Gateway space station and conducting longer-duration surface stays. For now, however, all eyes are locked on September 2026. The coordinates are set, the hardware is moving to the pad, and the countdown to a new era of lunar exploration has officially begun.
