... Together – Spacecraft Structure We’ve covered almost all the main subsystems that together form a spacecraft. Now we discuss the elements of the spacecraft that hold everything together – the structural components. The spacecraft structure provides the mechanical support to all the subsystems within the spacecraft (and the ...

... stars periodically. Because of the long durations, the spacecraft is assumed to be massive to house many people for many generations. The spacecraft is initially accelerated up to speed at great expense ... propulsion is assumed to be available for course corrections. The spacecraft, as it nears a star, follows a hyperbolic trajectory. The spacecraft returns by using gravity to "swing" around each of three ...

... propulsion system takes advantage of Coulomb spacecraft charging, saving on fuel consumed from the conventional electric/ion thrusters on-board the spacecraft. This would reduce the spacecraft mass, launch cost and enhance the life of the mission. The other advantages of the system are reduced payload contamination and improved spacecraft positioning. The ...
