Before you start coding the game itself, you’ll need to build the environment where the game will take place and begin to create rules for how that environment will operate.
In the top left corner, you’ll see the Data icon. Selecting this opens a menu that will allow you to add various map layers that NASA scientists have created over decades of Mars exploration by robotic spacecraft.
You’ll notice you can search by all layers, or you can select Product Type and filter by category. For example, try searching for the Perseverance Mars rover’s landing site. Select it to see some background information about the mission. Click the Add button at the bottom to add a map marker where the rover successfully landed.
