CAPE CANAVERAL, Fla.—NASA announced on Monday a rare, health-related delay in its SpaceX rocket launch of four astronauts to the International Space Station, the second postponement of the mission in a week, citing an unspecified medical issue with one of the crew.

NASA said the issue was “not a medical emergency and not related to COVID-19,” but the space agency declined to elaborate on the nature of the problem or say which astronaut was involved.
