In astrodynamics or celestial mechanics, a hyperbolic trajectory or hyperbolic orbit is the trajectory of any object around a central body with more than enough speed to escape the central object's gravitational pull. The name derives from the fact that according to Newtonian theory such an orbit has the shape of a hyperbola.In more technical terms this can be expressed by the condition that ...

Delta-v (more known as "change in velocity"), symbolized as and pronounced delta-vee, as used in spacecraft flight dynamics, is a measure of the impulse per unit of spacecraft mass that is needed to perform a maneuver such as launching from or landing on a planet or moon, or an in-space orbital maneuver.It is a scalar that has the units of speed.As used in this context, it is not the same as ...

So if you want improved jump distance, you'll have to invest in Astrodynamics itself. This is just something the game communicates poorly and I discovered this just by testing over and over. So unfortunately there is no quick fix to jump ...Introduction. All flight vehicles require a propulsion system to sustain flight, the only exception being a glider or a sailplane. The term propulsion means creating a force to propel some system forward. For example, a propulsion system for an aircraft, which is called an air-breathing propulsion system, consists of a mechanical power source ...The Tianwen-1 Mars entry vehicle successfully landed on the surface of Mars in southern Utopia Planitia on May 15, 2021, at 7:18 (UTC+8).
