To prepare astronauts for these demanding environments, NASA uses advanced simulation tools to create highly realistic landing scenarios. One of the technologies is GenesisLunar, developed by Diamond Visionics, LLC. This software generates dynamic, real-time visuals of the Moon’s surface, complete with accurate lighting, shadows, and even the subtle glow of Earthshine. For Mars training, similar visualization models allow astronauts to experience the red planet’s rugged landscapes and dusty atmosphere before ever leaving Earth.
Unlike traditional simulations that rely on static, prebuilt terrain models, GenesisLunar creates environments on-the-fly from raw imagery and elevation data. This means astronauts can practice landings on precise mission target zones, such as the Moon’s south pole – home to shadowed craters that may contain water ice – or Mars’ Jezero Crater, where future explorers will follow in the robotic footsteps of the Perseverance rover.
Why Simulation Matters
In spaceflight, there are no second chances. Every maneuver must be rehearsed, tested, and refined to minimize risk. High-fidelity simulations allow astronauts to experience the disorientation of dust clouds, the challenge of uneven terrain, and the need to make split-second adjustments under pressure. They also allow mission planners to evaluate landing technologies, refine procedures, and ensure that when astronauts take manual control, they are ready for anything.
