Specific angular momentum. In celestial mechanics, the specific relative angular momentum (often denoted or ) of a body is the angular momentum of that body divided by its mass. [1] In the case of two orbiting bodies it is the vector product of their relative position and relative linear momentum, divided by the mass of the body in question.Introduction. Aerospace engineering students soon begin to ask when they can start to solve actual problems relevant to aircraft, rockets, or spacecraft. Of course, it is natural to ask such questions, even early on in an engineering education.

Alternatively, you can choose a background at the start of the game that comes with it already unlocked, such as Explorer and Professor . Strictly speaking, the minimum ∆v is zero: from a ballistic capture trajectory, marginally stable lunar orbits at about 20,000 km altitude can be reached for zero or nearly-zero ∆v cost; an orbiter can then descend to a lower orbit at leisure using low-thrust high-efficiency ion engines.More generally, low energy transfers allow a tradeoff between travel time and insertion ∆v.The curriculum is designed to emphasize the disciplines of aerodynamics, aerospace systems, astrodynamics and space applications, autonomy and control, propulsion, and structures and materials.
