Determining a launch window from anywhere within a specified area to avoid or minimize close approaches between a launch vehicle and orbiting space objects. A method and apparatus is disclosed for minimizing close approaches, or conjunctions between spacecraft being launched from anywhere within a specified area and other objects in space during the launch and early deployment phase of their lifetime, by defining a launch window, utilizing and identifying launch window blackout times to avoid close approaches of launch trajectories from anywhere within an area with remaining objects in space as noted in a space object catalog.
