A re-entry corridor describes a region of Earth's surface where re-entry could occur given the current uncertainty window. It's better understood as a probability smear along the ground track than a target.
A re-entry corridor describes a region of Earth's surface where re-entry could occur given the current uncertainty window. It's better understood as a probability smear along the ground track than a target.
As re-entry approaches, fresh measurements progressively constrain the prediction.
The geometry of LEO means ground tracks spend most time over water — and re-entry timing is random within the uncertainty window.
A wide corridor is a sign of honest physics: the atmosphere is variable, object attitude is unknown, and timing cannot be pinpointed. Narrow corridors only emerge in the final hours.
