What do these do? Add it to the wiki!

If I remember correctly, they don't really do anything at the moment. They are experimental and not functional yet.

:( if I could make a suggestion, make the rocket able to carry turtles, then let it work with galacticraft. THAT would be cool. But the turtles would have to be upgraded, and you can visit each tier of GC only if your turtle is that tier

Yeah, these are currently WIP. While your turtle idea sounds neat, that is currently impossible with the way the CC API works. It is also a bit unnecessary considering you could just carry turtles in your inventory.

ya, but what if you wanted to journey there with a probe first?

So you want a GC expansion that allows for probes... This is a computercraft addon.

Are the satellites still experimental? I only ask as there are no upgrades for them listed. Also how do I access the programs for antenna usage?

Yes, satellites are still experimental so there are no programs for them yet. But to get the other programs for the antenna, type "cd ppp", then "cd antenna" and if you type in "dir" you should see all the mounted programs.
