Well, the map editor alpha is out. It's really buggy and needs a LOT of polishing but it's a really cool preview of what Version 2 is going to be like. If you want to download it and take a look, you can go to www.astrobattle.com/download/astromap.exe and see what you think.
WARNING- if you find that it isn't working, it's probably your graphics card. It has to be able to support Open GL 1.3. If it's not working, it may be that your graphics card is not up to par, or that you don't have the most current drivers installed.
I'll leave a few screenshots up in case people can't get the editor working. Here are the official ones as well as a couple of my own.
The two official screenshots are can be found here:
