[i]About two days prior to return, NASA and SpaceX teams will select primary and alternate splashdown target locations from the seven possible sites, with additional decision milestones about where Crew Dragon will splashdown taking place prior to the astronauts boarding the spacecraft, during free flight and before Crew Dragon performs a deorbit burn. Teams will evaluate the forecasted weather conditions at the primary and alternate splashdown sites at each milestone to determine if the sites are "GO" or "NO-GO" for splashdown and recovery. [b]Return Decision Milestones[/b] [list][*][b]Pre-Departure (1 to 2 days prior to approximate departure)[/b] SpaceX and NASA will jointly make the decision to depart 48 hours prior to splashdown based on the status of the primary and alternate splashdown sites. [*][b]6 hours before undocking[/b] NASA and SpaceX make a decision on primary splashdown target. [*][b]2.5 hours before undocking[/b] SpaceX will monitor changes to conditions until 2.5 hours prior to the scheduled undocking, when a determination to proceed with departure will be made. If conditions are marginal and exceed the accepted criteria, a joint recommendation by SpaceX and NASA will be made whether to proceed with undocking. [*][b]Undocking[/b] NASA and SpaceX will make the final decision to proceed after the astronauts are ready inside Crew Dragon just before undocking. [*][b]Free Flight[/b] Crew Dragon will proceed with departure phasing burns as planned even if conditions are marginal or NO-GO at any upcoming supported landing site and exceed the accepted criteria. Given the splashdown site may be 24 hours or more away and weather can change, Crew Dragon will always proceed with departure phase burns to preserve the supported splashdown opportunity. [*][b]Wave-off[/b] If conditions remain NO-GO at the supported splashdown site, SpaceX and NASA will jointly make a decision to "wave-off." In a wave-off scenario, Crew Dragon will remain in orbit for the next landing attempt 24-48 hours later. [*][b]5 hours before Deorbit (6 hours before Splashdown)[/b] If conditions at the splashdown site are marginal and exceed the accepted criteria, SpaceX and NASA will jointly make a decision about whether to proceed with deorbit. [*][b]Crew Dragon Claw Separation (1 hour, 20 minutes before Splashdown)[/b] SpaceX will monitor changes to conditions through the decision to proceed with the deorbit burn (30 minutes before claw separation prep), when a final determination to proceed with deorbit will be made. The claw is located on Crew Dragon's trunk, connecting thermal control, power, and avionics system components located on the trunk to the capsule.[/list][/i]
