Space Adventure is a zone added in the Space Update on March 9, 2018. It requires 500,000 blocks mined to unlock. Alternatively, you can buy access for 275 with the Space Pass.
In this zone, ores appear more frequently than in the main world, and are slightly more valuable. Rather than normal Stone, layers are made up of Space Stone. The quest giver is Spaceman Steve.
Based on a Mars-like planet, Space Adventure has three distinguishing visual elements: space suits, a giant Spacecraft, and alien-like flora. The shop has the appearance of a warehouse, and the sell area is the same but with a medium-sized crate. The path is very dull and only has a few tiny cubic lights, mostly in the corners.
