Missing Planets?

MC Version: 1.6.4
Forge Version: 9.11.1.965 MCP v8.11 FML v6.4.45.1 337
Mod Version: 4-Space Others-1.6.4-0.2.3-024
Description: Crash on Launch

I have only the following files in the mods folder:

4-Space Others-1.6.4-0.2.3-024.zip
Mattparks Core-1.6.4-0.2.3-024.zip
MicdoodleCore-1.6.4-2.0.12.1020.jar
Galacticraft-1.6.4-2.0.12.1020.jar
Galacticraft-Planets-1.6.4-2.0.12.1020.jar

Minecraft crashes shortly after launch complaining that it can't find Jupiter. I took a look in the 4-Space mod files and there only seems to be moons in the zip, no planets.
We can't have Callisto without Jupiter!

I'm sorry if I'm making an obvious mistake. I did try to follow the directions on the downloads page, am I missing a file?

Thank you,
Maize
