Trade & Diplomacy (if applicable)

Manage trade and Sponsors in Surviving Mars. Understand the Earth-Mars supply chain and Sponsor interactions for your colony's long-term viability.

While Surviving Mars doesn't feature traditional diplomacy with other factions or competing colonies in the base game, it does offer robust avenues for trade and resource management through the Earth-Mars supply chain and interactions with various Sponsors. Understanding these mechanics is crucial for long-term colony viability and expansion.

Earth-Mars Resource Exchange

Your primary "trade" partner is Earth itself, managed through your chosen Sponsor. This exchange is vital for acquiring advanced resources, specialized components, and even new colonists that cannot yet be produced on Mars.

Importing Resources

To import resources, you'll utilize the Rocket system. Follow these steps:

1. Access the Rocket Menu: Click on any active Rocket, or select the Rocket icon from the top-left UI panel (usually next to your resource counts).
2. Select "Load Cargo": This opens the cargo manifest for the selected Rocket.
3. Choose Resources: On the left side of the cargo screen, you'll see a list of available resources for import. These include:
   • Advanced Resources: Machine Parts, Electronics, Polymers. These are critical for constructing advanced buildings and vehicles.
   • Specialized Goods: Food (if your colony is struggling), Rare Metals (for early game funding), various building materials like Concrete or Metals (for emergencies).
   • Colonists: You can request specific types of colonists (e.g., Scientists, Engineers, Geologists) or general colonists.
4. Confirm Order: Specify the quantity of each resource or colonist type. Be mindful of the Rocket's cargo capacity and the cost in Funding.
5. Launch Rocket: Once loaded, click the "Launch" button. The Rocket will travel to Earth, acquire the goods, and return to Mars, landing at an available Rocket Pad.

Strategy Tip: Prioritize importing Machine Parts, Electronics, and Polymers early on, as these are prerequisites for many mid-to-late game structures and technologies. Only import basic resources like Concrete or Metals in emergencies, as they are easily produced on Mars.

Exporting Resources (Funding Generation)

The primary method of generating Funding (your colony's currency) is by exporting Rare Metals back to Earth. This is a cornerstone of a healthy Martian economy.

1. Mine Rare Metals: Construct Rare Metal Extractors over Rare Metal deposits. These require colonists to operate.
2. Store Rare Metals: Ensure you have sufficient storage, such as Universal Depots or Storage Tanks, for the extracted Rare Metals.
3. Load Rocket for Export: Select an empty Rocket or a Rocket that has just delivered imports. Access its cargo menu.
4. Select "Export Cargo": On the right side of the cargo screen, you'll see your colony's stored resources. Select Rare Metals.
5. Specify Quantity: Choose how many Rare Metals you wish to export. The UI will display the Funding you will receive.
6. Launch Rocket: Click "Launch." The Rocket will depart for Earth, selling the Rare Metals and returning with your earned Funding.

Strategy Tip: Automate Rare Metal exports by setting a minimum threshold on your Rockets. In the Rocket's cargo menu, you can set an "Export if above X" value for Rare Metals. This ensures a steady income stream without constant manual intervention. Aim to always have at least one Rocket dedicated to a continuous export loop once your Rare Metal production is stable.

Sponsor Interactions

Your chosen Sponsor dictates your starting Funding, initial resources, and provides various unique bonuses and challenges. While not direct diplomacy, understanding your Sponsor's traits is key to optimizing your trade strategy.

• International Mars Mission: Often provides balanced bonuses and a good starting point for general resource management.
• SpaceY: Focuses on rocketry and faster transport, making import/export more efficient. Ideal for a trade-heavy strategy.
• Europe: Generally provides more advanced technology and research bonuses, which can indirectly improve resource production efficiency.
• USA: Offers high starting Funding, allowing for more initial imports and a faster build-up.

Strategy Tip: Review your Sponsor's unique perks at the start of each game. Some Sponsors might offer reduced import costs for certain goods or increased export profits, which should influence your early game resource priorities.

Research & Breakthroughs Affecting Trade

Several technologies and Breakthroughs can significantly impact your trade efficiency:

• Advanced Martian Alloys (Engineering): Reduces the cost of importing Machine Parts.
• Automated Refineries (Engineering): Improves the production of advanced resources, reducing reliance on imports.
• Space Elevator (Wonder): A late-game Wonder that completely bypasses Rockets for resource transfer, offering instant, high-volume import/export at a reduced cost. This is the ultimate trade upgrade.
• Various Breakthroughs: Keep an eye out for random Breakthroughs that might offer bonuses to resource production, reduce import costs, or increase export profits. For example, "Self-Sufficient Drones" can reduce maintenance costs, freeing up Funding for imports.

Strategy Tip: Prioritize research that enhances your ability to produce advanced resources locally (e.g., Machine Parts, Electronics, Polymers) to reduce your dependency on expensive imports. Once your internal production is robust, focus on maximizing Rare Metal exports to maintain a healthy Funding reserve.
