About Deep Field
Master Real Orbital Physics
Take command of a space program built on authentic aerospace principles, where every mission is governed by Newtonian motion, Keplerian orbits, and patched-conics transfers between celestial bodies. Plan gravity assists, insertion burns, and return windows with precision as your trajectories evolve in real time. A detailed thermal simulation and practical fuel management system turn every maneuver into a meaningful tradeoff between efficiency, safety, and mission success.
Design Spacecraft With Purpose
Build mission-ready vehicles from the ground up and tune each craft for the job ahead, from launch stacks to deep-space transfer ships and assault crafts. Balance thermal limits, thrust-to-weight ratio, and specific impulse (ISP) to create designs that can survive travel and combat under hostile conditions. Choose engines, tanks, radiators, and structural layouts that support your mission profile, then iterate as failures and discoveries push your engineering further.
Coordinate a Team Across the Solar Frontier
Join a team, coordinate launches, and combine engineering, navigation, and logistics to capture moons and planets across a living star system. Manage shared resources, production pipelines, and mission priorities as multiple expeditions compete for time, fuel, and funding. Expand your reach through careful planning and teamwork, turning isolated missions into a sustained, cooperative campaign of exploration and planetary capture.
