After fifty years of pursuit across 1.5 light-years, Gravity approaches within three AU of Blue Space, having maintained a higher speed and outplayed it on fuel knowledge.

Gravity refuses Blue Space's partial surrender offer; at fifteen AU, Blue Space announces surrender and decelerates, so Gravity's crew wakes and prepares for combat.
