In part II, we looked at the need for gravity aboard manned spacecraft, and how we might go about achieving artificial gravity in deep space. In this part, we’ll discuss different propulsion systems that might be used on future spacecraft to cross vast distances in reasonable periods of time.
In part I, we examined the size and design elements of future manned spacecraft. Now we will look at the need for gravity aboard manned spacecraft, and how we might go about achieving artificial gravity in deep space.
