SimpleRockets 2 requires 2GB of RAM.
SimpleRockets 2 is a fully 3D space sim that lets you build rockets, airplanes, rovers, or anything you can imagine and explore highly detailed 3D planets. Easily share crafts and saved games with the community. Included are 17 different challenges to put your creations to the test.
Build crafts by snapping parts together. Choose from the pre-built engines, such as the Mage, which is a powerful kerosene-fueled engine. Or choose the very weak, but highly efficient Ion Engine. Or you can dig deeper into the complexity of rocket science and design your own rocket engines. Choose from the eight available engine types, seven nozzles, and six fuel types. From there you can change engine size, nozzle length, throat radius, and more.
Use interstages to split your craft into multiple stages and piece together modular fairings to protect your precious cargo. Launch multiple crafts into orbit. You can dock with your existing crafts to build space stations, moon bases, refueling stations, etc.
Resize and reshape fuel tanks, wings, cargo bays, fairings, and nose cones with easy-to-use tools that help you create exactly what you want. Resize solar panels, wheels, pistons, shocks, etc to fit your needs. Paint your craft custom colors and tweak their reflectiveness, emissiveness, and texture styles.
Orbits are realistically simulated and support time-warp so you don't have to wait several months to reach another planet. The Map View makes it easy to see your orbits and plan future burns, which you can use to set up future encounters with other planets or satellites.
The flight model dynamically updates drag and lift characteristics of your craft as it changes. Re-entry effects kick in when you're screaming through an atmosphere at hypersonic speeds. Be careful, because the excessive heat can cause those aforementioned rapid unplanned disassemblies.
