Read the explanation

This explainer traces the saved separation simulator assumptions, not a live mission report. The default separation speed is point four two meters per second. Straight-line motion for three hundred seconds gives one hundred twenty-six meters. At six hundred seconds it gives two hundred fifty-two. Both bars use two pixels per meter. The source multiplies speed by time and uses the Euclidean length of horizontal and vertical components, so changing alignment rotates the vector without changing this distance magnitude. The source declares clearance at one hundred twenty meters. It divides that distance by separation speed to estimate threshold time. At point four two meters per second the threshold is about two hundred eighty-five point seven one seconds; at point six it is two hundred seconds. Both bars use one point five pixels per second. This toy threshold does not include gravity, contact dynamics or trajectory uncertainty. Alignment offsets beyond ten degrees and speeds below point two independently flag a source hazard. The milestone buttons display mission-style clock labels, but the source clamps every selected time to at most twelve hundred simulation seconds. Both the fourteen-thirty button, whose metadata is eighteen hundred seconds, and the fifteen-fifty-three button, whose metadata is six thousand seven hundred eighty, therefore set twelve hundred. At the default speed both produce five hundred four meters. Both bars use one pixel per meter. The exact source clamp is preserved; clock labels are not an independent reconstruction of mission elapsed time.
