// ORBITAL LOGISTICS AND PROPULSION TERM
Delta-V
A measure of the change in velocity required to perform an orbital maneuver, like changing altitude or direction. It's essentially the 'fuel budget' for space missions.
TECHNICAL DEFINITION
Delta-V (Δv) quantifies the total change in velocity a spacecraft needs to execute orbital maneuvers, such as orbit insertion, rendezvous, or plane changes, directly correlating with propellant consumption.
BACKGROUND
Buckley Space Force Base is a United States Space Force base in Aurora, Colorado named after United States Army Air Service First Lieutenant John Harold Buckley. The base is run by Space Base Delta 2, with major units including the U.S. Space Force's Space Delta 4, the Colorado Air National Guard's 140th Wing, the Denver Naval Operations Support Center, and the National Reconnaissance Office's Aerospace Data Facility-Colorado.
