NASA engineers at the Marshall Space Flight Center in Huntsville are simulating the Moon’s unique lighting environment to better prepare for the Artemis III mission. Using the Flat Floor Facility—an 86‑ft‑by‑44‑ft air-bearing surface—they recreate the lunar South Pole’s extreme low-angle sunlight and deep shadows with high-intensity 12‑kW and 6‑kW lights, mock lunar terrain, and reflective fabric replicating lunar regolith.
This human-in-the-loop testing allows engineers and astronauts to experience firsthand how harsh contrasts impact visibility during critical tasks like lander inspection or accessing equipment. Shadows behind terrain can stretch meters—or even miles—creating striking visual challenges.
The Flat Floor’s frictionless surface enables teams to easily reposition mock-ups and evaluate tool usability from different angles. The collected data helps refine simulation models and testing protocols, ensuring mission success and astronaut safety during Artemis III surface operations.
Broader Context and Relevance
Why It Matters: Landing near the lunar South Pole presents unprecedented lighting hurdles. The constant sun skimming the horizon produces blinding glare and pitch-black shadows, making everyday tasks difficult for astronauts. These environmental simulations are vital for designing both spacecraft systems and training programs.
Artemis III Mission Snapshot: Scheduled no earlier than mid-2027, Artemis III aims to deliver astronauts to the lunar South Pole using SpaceX’s Starship HLS—marking the first crewed Moon landing since Apollo 17.
Advanced Prep Tools: Alongside lighting tests, NASA is also developing augmented reality and mixed reality tools—such as the DUST and ARGOS systems—to simulate terrain and gravity effects during lunar operations.
Summary
By simulating lunar lighting in a controlled Earth environment, NASA is tackling one of the Moon’s most deceptive challenges—extreme contrast and shifting shadows—long before Artemis III lands. Combined with advanced simulation tools and preparation, this work ensures astronauts and mission planners are ready to navigate the lunar South Pole’s stark light and dark cycles.
