This dual-platform approach leverages the strengths of both tools for detailed visualization and practical simulation.

Stand-alone, which is better for this purpose?

The better choice between Blender and Unity 3D for displaying lunar terrain, adding 3D assets, and planning lunar exploratory missions depends on your specific goals. Here's a breakdown to help you decide:

Blender

Blender excels at high-quality 3D modeling, rendering, and visualization but lacks robust real-time interactivity.

Strengths:

Realistic Rendering:
- Ideal for photorealistic still images or animations of lunar terrain and mission scenarios.
Precise Asset Creation:
- Powerful tools for creating and refining detailed 3D models of rovers, landers, and the lunar surface.
Non-Interactive Visualizations:
- Great for presentations, concept art, or pre-rendered mission planning visualizations.
Cost and Accessibility:
- Free, open-source, and supported by a vast community with many tutorials.

Weaknesses:

Lack of Interactivity:
- Cannot natively support real-time exploration or user-driven simulations.
Physics Simulations:
- Limited to non-real-time animation; not suitable for dynamic simulations like rover movement.

When to Choose Blender:

You need high-quality renders for presentations, research papers, or mission briefs.
The focus is on asset design and pre-rendered visualization, not interactivity.

Unity 3D

Unity is the go-to platform for real-time simulations and interactive applications.

Strengths:

Real-Time Interactivity:
- Users can explore the lunar terrain, test mission scenarios, and interact with assets dynamically.
Physics Simulation:
- Built-in physics engine for simulating rover movement, low gravity, and terrain interaction.
Mission Planning Tools:
- Allows integration of waypoints, navigation systems, and telemetry data overlays.
Extensibility:
- Scripted behaviors and AI for autonomous entities.
- Potential to scale to VR/AR for immersive mission planning.
Deployment Options:
- Applications can be exported for various platforms (PC, mobile, VR).

Weaknesses:

Steeper Learning Curve:
- Requires knowledge of scripting (C#) for customizations.
Asset Creation Dependence:
- While you can create terrains and models, it's less robust for detailed asset design compared to Blender.
Licensing for Advanced Features:
- Free version works well, but advanced tools may require a paid license.

When to Choose Unity 3D:

You need a real-time, interactive framework for mission planning or simulations.
The focus is on building tools for exploration, navigation, or immersive experiences.

Stand-Alone Recommendation:

If you prioritize visualization and design: Go with Blender.
If you prioritize interactivity and simulation: Choose Unity 3D.

For lunar exploratory missions, where real-time simulation and interaction are key, Unity 3D is the better stand-alone choice. It offers the flexibility to simulate realistic physics, integrate dynamic mission elements, and create user-driven scenarios, making it more suitable for exploratory mission planning.

Seems like I might design static environments in Blender and import that to Unity 3D for interactive simulations

You're absolutely correct! Designing static environments in Blender and then importing them into Unity 3D for interactive simulations combines the strengths of both platforms and is a common workflow in 3D design and simulation. Here's how this workflow would look:

1. Design Static Environments in Blender

Blender is ideal for crafting detailed, realistic lunar terrain and assets:

Steps:

Create the Lunar Terrain:
- Use NASA heightmap data to sculpt accurate lunar surfaces.
- Add realistic textures, such as regolith and crater details, using procedural materials or image-based textures.
- Apply displacement modifiers to bring out surface details.
Design Mission Assets:
- Create detailed 3D models of rovers, habitats, and landers.
- Rig any assets (like robotic arms or wheels) that require animation or interaction.
Optimize for Export:
- Reduce polygon count if needed to make assets game-engine friendly.
- Apply texture baking to simplify material setups.
- Export assets in Unity-compatible formats (e.g., FBX, OBJ, or GLTF).

2. Import Blender Assets into Unity 3D

Once the environment and assets are ready, you can bring them into Unity for interactivity:

Steps:

Import Assets:
- Drag-and-drop FBX/OBJ files into Unity's project window.
- Verify that the materials and textures are correctly applied (Unity may require some tweaking).
Set Up Terrain:
- Place the imported lunar terrain in the Unity scene.
- Use Unity's Terrain system if additional modifications (like dynamic craters or hazards) are needed.
Integrate Mission Assets:
- Position rovers, landers, and other mission-critical items in the scene.
- Add Unity components like Rigidbody and Colliders for physical interactions.

3. Add Interactivity in Unity

This is where Unity shines, allowing you to bring the scene to life:

Steps:

Physics and Movement:
- Add scripts in C# for rover controls (e.g., WASD or joystick input).
- Simulate low-gravity physics by adjusting Rigidbody mass and drag settings.
Mission Planning and Visualization:
- Add UI elements to display telemetry, objectives, and navigation markers.
- Use LineRenderer to visualize paths for rovers or astronauts.
AI and Automation:
- Implement AI for autonomous navigation or obstacle avoidance using Unity’s NavMesh system.
Real-Time Adjustments:
- Test interactions like rover movement on the terrain or sample collection.
- Add triggers for events (e.g., reaching a waypoint or detecting an obstacle).

4. Iterate and Refine

Adjust the environment in Blender as needed based on Unity testing feedback (e.g., improve terrain resolution or fix asset proportions).
Reimport updated assets into Unity, leveraging its prefab system for quick updates.

Why This Workflow Works Well

Blender Strengths:
- Provides advanced modeling and rendering tools for creating visually stunning environments and assets.
Unity Strengths:
- Excels at real-time interactivity, physics simulation, and multi-platform deployment.
Flexibility:
- Blender's high-quality static designs become the foundation for Unity's interactive and dynamic simulations.

Potential Use Cases for This Workflow

Lunar Mission Training Simulations:
- Teach astronauts or operators how to navigate or interact with equipment on the lunar surface.
Educational Tools:
- Provide students with an interactive lunar sandbox to explore and learn.
Mission Prototyping:
- Simulate mission scenarios to test rover designs or plan exploration routes.

By leveraging Blender for static designs and Unity for interactivity, you create a powerful pipeline that is efficient and versatile.
