Ad Astra Mod (1.20.4, 1.20.1) – Explore The Universe

Ever wished Minecraft had a full-blown space program? Ad Astra Mod turns that dream into reality by adding five explorable planets, tiered rockets, oxygen systems, and over 250 new building blocks — essentially transforming your survival world into an interplanetary sandbox. With over 4 million downloads on Modrinth since its 2022 release, it has quickly become one of the most popular space exploration mods in the community. Whether you want to brave the freezing surface of Mars or endure Mercury's scorching heat, Ad Astra gives you the machines, vehicles, and spacesuits to make it happen.

Key Features

• Five Explorable Planets — Travel to the Moon, Mars, Venus, Mercury, and Glacio across two solar systems. Each celestial body features its own unique terrain, atmosphere, and environmental hazards that demand different survival strategies.
• Tiered Rocket System & Rover — Build and upgrade through four rocket tiers to reach increasingly distant planets. Once you land, deploy a rover to navigate rough alien terrain without burning through your fuel supply.
• Full Technology Tree — Craft processing machines, generators, oxygen distribution systems, and fuel refineries. The tech progression feels natural — you start small and scale up as you prepare for deeper space missions.
• 250+ Building Blocks — Decorate your bases with planet-specific bricks, stones, and space station panels. Whether you are building a lunar outpost or an orbital hub, there is no shortage of aesthetic options.
