A highly detailed matrix governs the go/no-go decision for a launch. If key metrics are not attained—or specific incidents occur during the countdown sequence—the mission aborts. As Hurley recounted in a tweet, “On my first flight STS-127 on Shuttle Endeavor, we scrubbed 5 times over the course of a month for technical and weather challenges. All launch commit criteria is developed way ahead of any attempt. This makes the correct scrub/launch decision easier in the heat of the moment.” Behnken also recalled his experience: “Scrubs are a part of conducting spaceflight safely and successfully. During my last mission to @Space_Station weather caught us too!” During the crew’s travel in orbit to ISS, they revealed that they had named their capsule Endeavor.
