SpaceX launch delayed due to astronaut 'minor medical issue'

A SpaceX launch has been delayed because of a ‘minor medical issue' involving one of the four astronauts

CAPE CANAVERAL, Fla. -- A medical issue has sidelined one of four astronauts assigned to SpaceX’s upcoming flight to the International Space Station and delayed the launch, officials said Monday.

NASA said the launch is now off until Saturday night at the earliest. Liftoff had been scheduled for this past Sunday, but bad weather offshore bumped it to Wednesday. It's the first time in decades that a U.S. flight has been delayed by a crew member's health.

Officials would not say which astronaut is affected. They described it as a “minor medical issue” and said it is unrelated to COVID-19. The one German and three U.S. astronauts — who range in age from 34 to 61 — have been quarantined for two weeks as usual before a spaceflight.

Once on their way, Raja Chari, Tom Marshburn, Kayla Barron and the European Space Agency's Matthias Maurer will move into the space station for six months, replacing four astronauts who have been living up there since April. NASA prefers launching the new crew before bringing back the old one so they can have a face-to-face handover, but is considering “all options” in light of the latest delay.
