Usage of Manned and Unmanned

While manned and unmanned are still commonly used in news sources to describe spaceflights with and without human crews, respectively, NASA has since the early 21st century used and prescribed non-gender-specific terms, preferring such descriptors as human, piloted, and crewed for the former, and unpiloted and uncrewed for the latter.
