NASA will launch an extensive “safety review” of operations and workplace culture at SpaceX and Boeing—two companies the space agency has commissioned to fly astronauts to the International Space Station (ISS).

According to The Washington Post, three officials with knowledge of the inquiry revealed that it had been announced due to the recent behavior of SpaceX’s founder Elon Musk, who smoked marijuana and drank whiskey on "The Joe Rogan Experience" podcast. While many might view his actions as relatively harmless, top NASA officials were reportedly unhappy with Musk.
