Space: The Final Fontier

This modpack utilizes Galacticraft Legacy to allow you to travel to many different planets in our solar system. You can craft different tiers of rockets using many new ores to blast off to new worlds or you can make a rover which you can ride in order to explore other planets with great speed. It also allows for you to make your own space station which you must craft using ores such as tin, copper, and aluminum which you can find underground. Also, you could use the quarry feature from Buildcraft which allows you to walk away and let the quarry mine out an entire area for you in a predetermined area. Lastly, you can build nice even bases using the Better Builder's wands mod. The Better Builder's wands mod allows you to build walls, ceiling and floors with many blocks at once, it allows you to build blocks at the same length of whatever wall/ceiling/floor that you are looking at.
