CosmoLaunch System

CosmoLaunchSystem is a hybrid game about running a space agency: combining budget and contract management with rocket building and physics-based 2D flight. You are the agency director. You accept contracts, invest in research laboratories, design launch vehicles in the VAB, and deliver client payloads—ranging from early suborbital flights to LEO, GEO, and narrative-driven space telescope missions, as well as CubeSat systems that allow you to launch various scientific instruments into orbit for your clients. Who You AreSpace agency director.

You don’t just fly—you decide what to build, when to launch, and how much to risk your reputation and budget. Bad weather, untested designs, and mid-flight failures can destroy a client's payload. Good decisions unlock lucrative contracts and milestone steps in exploration. Build Like an EngineerIn the modular VAB editor, you assemble rockets from parts: liquid engines, SRB boosters, fairings, RCS thrusters, fins, command pods, and payloads. See real-time mass, thrust, TWR, Delta-V, and Center of Mass. Save proven designs, upgrade your hangar, and roll out vehicles to the pad.

Tuck delicate payloads inside aerodynamic fairings, and mount scientific instruments directly onto the rocket body. Fly and Reach OrbitControl throttle and pitch in a realistic atmosphere—complete with drag, Max Q, and the risk of structural failure from pilot error. For stable orbit missions, a pitch guidance radar helps with recommended ascent profiles to reach the target orbit, but the final outcome is up to you.…
