Delta-v (also known as "change in velocity"), symbolized as and pronounced /dɛltə viː/, 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.

Kerbal Space Program 2 planned to build on the sandbox features of its predecessor, Kerbal Space Program, by adding elements such as new propulsion methods (e.g. the Orion drive), habitation modules for building on-surface, orbital and planetary colonies, a multiplayer mode, as well as interstellar travel [81] [82] throughout the course of its ...
Kerbal Space Program 2 is a space flight simulation video game developed by Intercept Games and published by Private Division. It is the sequel to 2015's Kerbal Space Program and was released on early access on February 24, 2023, for Windows .
While they require one more engine burn than a Hohmann transfer and generally require a greater travel time, some bi-elliptic transfers require a lower amount of total delta-v than a Hohmann transfer when the ratio of final to initial semi-major axis is 11.94 or greater, depending on the intermediate semi-major axis chosen. [2]
In some cases, it can require less total delta-v to raise the satellite into a higher orbit, change the orbit plane at the higher apogee, and then lower the satellite to its original altitude. [ 1 ] For the most efficient example mentioned above, targeting an inclination at apoapsis also changes the argument of periapsis .
Their one-way delta-v budgets from LEO range upwards from 3.8 km/s (12,000 ft/s), which is less than 2/3 of the delta-v needed to reach the Moon's surface. [10] But NEOs with low delta-v budgets have long synodic periods, and the intervals between times of closest approach to the Earth (and thus most efficient missions) can be decades long. [11 ...
