This project is a 3D space rover simulator you run in a web browser, built with a JavaScript graphics library called Three.js. It drops you into a rocky, sunset-lit valley that you drive a rover around, similar to a small driving game rather than a real scientific tool. You can control the rover with the keyboard, using W, A, S, D or the arrow keys, or with an on-screen D-Pad button layout, which suggests it also works reasonably on a touchscreen or mobile device. Driving has acceleration and deceleration built in rather than instant starts and stops, so the rover has some weight and momentum to it. A distance sensor also checks how close the rover is to the nearest rock, and the simulator detects collisions so you cannot just drive through obstacles. While driving, an on-screen dashboard shows live telemetry: the rover's X and Z position, its current speed, and the distance reading from the nearest obstacle sensor. This information is laid out in glass-style panels tucked into the corners of the screen so the 3D view itself stays as large as possible. The camera follows the rover from a third-person view and stays locked onto it as you drive, but you can still drag with the mouse to rotate the view around the rover and scroll to zoom in or out, without losing the camera's lock on the vehicle. The code itself is small and split into three files: an HTML file for the page structure and heads-up display, a CSS file for the glass-panel styling and full-screen layout, and a JavaScript file that sets up the Three.js scene, the rover's physics, the camera, and the collision checks. There is no build step or server described, so it looks like a project meant to run directly in the browser once the files are loaded.
