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.

[2] [3] [4] The Fortune 500 company delivers a range of engineering services, manufactures industrial automation equipment, climate control systems, and precision measurement instruments, and provides software engineering solutions [buzzword] for ...
The accompanying diagram is a general model which shows functional manufacturing levels using computerised control. Referring to the diagram; Level 0 contains the field devices such as flow and temperature sensors, and final control elements, such as control valves
In 1945, Rockwell Manufacturing Company acquired Delta Machinery and renamed it the Delta Power Tool Division of Rockwell Manufacturing Company and continued to manufacture in Milwaukee. In 1966, Rockwell invented the world's first power miter saw. In 1981, Rockwell's power tool group was acquired by Pentair and re-branded Delta Machinery.
The quicker a high delta-v manoeuvre can be executed, the higher the efficiency of this manoeuvre, and the less propellant is required. This reduction in the propellant required can be directly translated to an increase in the bus and payload mass (at design stage), enabling better science return on these missions.
Delta-v in feet per second, and fuel requirements for a typical Apollo Lunar Landing mission. In astrodynamics and aerospace, a delta-v budget is an estimate of the total change in velocity (delta-v) required for a space mission. It is calculated as the sum of the delta-v required to perform each propulsive maneuver needed during

The cost of space transport is directly related to the delta-v, or change in velocity required to move from the mining sites to the manufacturing plants. Bringing material to Earth orbit from bodies such as Near-Earth asteroids , Phobos , Deimos or the lunar surface requires far less delta-v than launching from Earth itself, despite the greater ...
