One of the hard parts of tracking launchers is knowing where to point. The trajectory is fixed, but the time is not. We slide the trajectory clock as close as we can, then tighten it up after acquisition. Then fresh, actual trajectory data comes and it's easy. Today GHY-6 nailed Orion, and we're working through the cubesats. So far so shiny. #artemis1 #goonhilly #spaceops
