• 🚀 Build functional rockets and launch pads
• 🌕 Travel to The Moon, Mars, Venus, Mercury, and more
• 🏠 Construct space stations and planetary bases
• 🌬️ Manage oxygen, pressure, and temperature for survival
• 🔧 Tech progression including machines, fuel production, and solar power
• 🪨 Unique planetary ores and exclusive crafting materials
• 👽 Encounter custom biomes, structures, and mobs

• Mine basic resources and craft early machines:
  • Compressor
  • Fuel Refinery
  • NASA Workbench
• Build your first rocket using the NASA Workbench
• Craft an Oxygen Suit and gear — space is deadly without it
• Set up a launch pad, fuel the rocket, and prepare for takeoff
• Use the rocket GUI to select your destination and launch

Each planet has unique conditions, resources, and building challenges:

• 🌑 Moon – Low gravity, meteoric iron, basic base-building
• 🔴 Mars – Redstone, ice caves, Martian soil
• 🟡 Venus – Extreme heat, acid rain, sulfur gas
• 🟠 Mercury – High radiation, solar ore
• 🛰️ Space Stations – Build orbiting bases with solar power

More planets and moons may be added via optional mod extensions or future updates.

• You must wear a full space suit with oxygen gear and tanks
• Use Oxygen Loaders and Distributors to make breathable areas
• Some planets require thermal padding or gas protection
• Solar panels work better the closer you are to the sun

If you launch unprepared, you will suffocate or burn to death almost immediately.

• Each planet offers exclusive ores for advanced machines
• Automate fuel production with oil extractors and refineries
• Build solar farms or nuclear generators for clean energy
• Create fully self-sufficient off-world colonies

• Bring building materials, food, and extra oxygen tanks before launching
• Test rocket placement on flat ground — pad space matters
• You can return to Earth using the same rocket
• Keep an eye on fuel level, or you’ll be stranded
