Usage of Manned and Unmanned

While manned and unmanned are still commonly used in news sources to describe spaceflights, 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.
