The Generic Spacecraft is an evolving prototype real-time simulation of a spacecraft that can orbit the Earth and land on the Moon, and eventually Mars. This simulation, which serves as a test bed for modeling space vehicle dynamics, propulsion, control systems, guidance, and displays, is the Langley Standard Realtime Simulation in C++ (LaSRS++) framework.

PlanetaryBalloon is a windows-like balloon-design software package. By including the effects of circular lobes with load tapes, skin mass, and hoop stress in the lobed bulges, a more accurate balloon shape of practical construction can be determined along with the room temperature cut pattern for the gore shape.
