NASA's Lunar South Pole Landing Plan Draws Astronaut Pushback 2026

NASA's plan to land astronauts at the lunar south pole is facing unexpected criticism from within its own ranks. Victor Glover, the pilot of the upcoming Artemis II mission, has publicly questioned whether the south pole is the safest choice for the first crewed landing of the Artemis program, arguing that the lunar equator would be a better option.

Glover's comments, made this summer, come as NASA prepares for Artemis III, a mission designed to test docking maneuvers with lunar vehicles from Blue Origin and SpaceX. The actual landing is scheduled for Artemis IV in 2028, but the debate over where to touch down is already heating up.

Why NASA Wants the Lunar South Pole

The lunar south pole has been a top target for NASA because of its potential water ice deposits. Permanently shadowed craters near the pole are believed to hold frozen water that could be used for drinking, oxygen, and rocket fuel. This resource could be key to establishing a sustainable presence on the Moon.

However, Glover's concerns highlight a trade-off between scientific potential and operational safety. The south pole's extreme lighting conditions and challenging orbital mechanics could complicate the first landing attempt.

Glover's Two Main Concerns

Light and Power

At the lunar equator, day and night are more evenly distributed, with each lasting about two weeks. This predictable cycle makes it easier to plan solar power generation. At the south pole, the Sun stays low on the horizon, leaving many areas in near-constant shadow.

If a lander sets down in one of these shadowed regions, it would receive less solar energy to power its systems. That could limit mission duration and increase reliance on batteries or other power sources.

Orbital Mechanics

The Orion capsule will rendezvous with the lander in lunar orbit. Astronauts will transfer to the lander, which then separates and descends to the surface. The orbital path and timing of this maneuver are more complex at the south pole due to the Moon's rotation and the need for precise alignment.

Glover suggests that landing near the equator would simplify these operations and reduce risk for the first crewed landing.

What This Means for Artemis IV

Artemis IV is still years away, but decisions made now will shape the mission's architecture. NASA has not indicated any plans to change the landing site, but Glover's remarks could spark further discussion within the agency and among its partners.

The debate also underscores the challenges of balancing exploration goals with astronaut safety. As the first crewed landing since Apollo 17 in 1972, Artemis IV will be closely watched. The background to this story is set out in NASA's Lunar Caves: PRISM Missions to Scout Astronaut Shelters. A related thread runs through NASA Creates Emeritus Astronaut Title as Retirements Rise. Earlier coverage in Artemis II Crew Earns Top US Space Medal for Lunar Mission shows how the argument developed.

• Artemis II is a crewed flyby of the Moon, currently planned for 2024.
• Artemis III will test docking with commercial landers from Blue Origin and SpaceX.
• Artemis IV is the first planned landing, targeted for 2028.
• The lunar south pole offers water ice but has challenging lighting and orbital conditions.
• Astronaut Victor Glover advocates for an equatorial landing to reduce risk.

What to Watch Next

NASA will continue to refine its Artemis plans as the missions progress. The agency has not yet responded publicly to Glover's comments, but the discussion is likely to continue as Artemis II approaches.

The same theme surfaces in NASA Sends Three Fully Autonomous Robots to the Moon, which takes a different angle.

For now, the lunar south pole remains the official target for Artemis IV. Whether that changes will depend on how NASA weighs the risks and benefits in the coming years.
