The mod adds a few cool stuff, first off, a space suit made of cloth, a space rocket, the moon and other stuff too. Saddly so far the mod only has the moon, soon however, it will have the entire solar system. Only Glowstone works to light the moon up, you cant use torches or redstone lamps (the lever will pop off). To get to the moon, make a portal out of iron blocks and light it with the space rocket item, after that you can set off into space and explore the solar system! It also has an unbreathable atmosphere and all items that dont work without air, torches ect. will be destroyed and pop off! To survive, you will need a space suit, this is made by the recipie in the images above, this will let you breethe in the moons atmosphere, aswell as under water!
