Asteroid Harvester

Design and operate a growing fleet of rockets to mine resources from orbiting asteroids and bring them back to Earth. The game blends hands-on rocket construction with realistic orbital mechanics, inviting you to optimize every mission from build to return while balancing risk and reward.

Every asteroid carries its own physically accurate orbit—elliptical, parabolic, or hyperbolic—shaped by gravity and time. An automated orbit engine tracks positions and calculates viable launch windows, predicting intercept opportunities so you can plan precise maneuvers as the skies evolve around you.

• Build and customize rockets with a range of engines, propellants, guidance systems, and harvest gear. Choose light, fast scouts for early targets or sturdy haulers for heavy freight. Each component affects delta-v, burn time, docking compatibility, and how efficiently you can extract and store minerals on the way back to Earth.
• Attach harvest modules that convert asteroid material into cargo. From in-situ crushers and concentrators to compact refining units, tailor the processing chain to maximize yield, reduce mass, and streamline the journey home. The better your extraction line, the more profitable and reliable your missions become.
• Plan aerobraking, deceleration, and attitude control with precision thrusters to slow or steer asteroids, making close approaches safe or nudging a body toward a controlled Earth return. Mastering these maneuvers lets you harvest high-value targets without risking destabilization or uncontrolled reentry.
• Safety first: the system continuously evaluates trajectories to prevent a catastrophic asteroid impact with Earth. Mis-timed burns or overly aggressive pushes can threaten the planet, so you’ll rely on simulations, abort options, and layered returns to keep your operation sustainable and secure.

Goal and progression: build a scalable harvest network, maximize cargo yields, and establish steady resource shipments to Earth. Balance fleet size, fuel, and risk as asteroid orbits evolve, unlock new modules, and refine your strategies to turn space resources into earthbound prosperity.
