In March 2019, Vice President Mike Pence instructed NASA to do something rarely seen in space projects: move up a schedule. Speaking at a meeting of the National Space Council, Pence noted that NASA's plans for returning humans to the moon called for a landing in 2028. “That's just not good enough. We're better than that,” he said. Instead, he announced that the new goal was to land humans on the moon by 2024.

登月的三种方式：NASA 将很快缩小载人登月的可能策略

2019 年 3 月，副总统迈克·彭斯指示 NASA 做一些太空项目中很少见的事情：提前计划。彭斯在国家航天委员会的一次会议上发表讲话时指出，美国宇航局将人类送回月球的计划要求在 2028 年登陆。“这还不够好。我们比那更好，”他说。相反，他宣布新目标是到 2024 年让人类登上月球。
