Here is a battle-grid for space combat, which I’ll call Configuration Radius-Alpha. Both white background and black background are available, and there is a flipped version, so you can print out two of each on 8 1/2″ x 11″ paper to assemble a large, circular battlefield. (This one is compatible with a map in the upcoming Starter Set.)
If you have Photoshop or other image-editing programs, you can use the black background image with the ‘Screen’ blend mode to overlay the grid onto an image. With some effort you can create a full-colour battlemap such as the one below (image borrowed from the end-credits of Star Trek Into Darkness). Click on the link to obtain a 4-page PDF that you can assemble into a mega battle-grid.
For those who have access to a colour printer that is capable of tabloid-length, here is a 2-page PDF version.
There will be other zone types available in the future.
