Just hours after Musk’s space flight company, SpaceX, delayed the launch of a cargo capsule on Saturday morning, the billionaire launched something else: a needlessly bad tweet. At 2:17 am Eastern on Saturday, SpaceX announced on Twitter it had delayed the launch of its CRS-28 mission, which aims to carry supplies from Florida to the International Space Station, citing weather concerns and “vehicle preparations.” The new launch is set for Monday. A little over five hours later, the company’s founder and CEO weighed in on a controversy involving a transgender student using the girls’ locker room at a Vermont high school. In response to a tweet from Riley Gaines, a former collegiate swimmer who has advocated against allowing trans students to compete in women’s sports, Musk voiced support for a Vermont high school student who was reportedly disciplined after trying to prevent a fellow student, who is trans, from using the girls’ locker room.
