  • The white line and shaded area show day and night around the globe
  • The blue line shows the orbital path prior to reentry, and each tick mark is a five-minute interval
  • The yellow line is the predicted future path with tick marks at five-minute intervals
  • The text label and satellite icon indicate where the rocket body ultimately reentered
  • The circle around the reentry point is the vicinity in which the reentry could be seen

This plot shows the history of predictions over time. The dots are predicted reentry date and time, and the vertical bars represent the nominal error of the estimated reentry. The prediction is currently holding steady for Saturday night (US time), and the error bars are shrinking. Credit: The Aerospace Corporation
