deltavtotal
Delta-v, often written as Δv, is a fundamental concept in orbital mechanics and astronautics. It represents the change in velocity required to achieve a specific orbital maneuver. Think of it as the "effort" or "cost" in terms of velocity change needed to move from one orbit to another, or to change the trajectory of a spacecraft.
This change in velocity is a crucial metric for mission planners because it directly relates to the
Different maneuvers have different delta-v requirements. For instance, escaping Earth's gravity requires a significant delta-v. Changing
The total delta-v for a mission, often denoted as delta-v total or Δv_total, is the sum of
