SpaceX fixes Crew Dragon toilet after Inspiration4 mishap
CNN
A problem with the Crew Dragon toilet was first identified during SpaceX's Inspiration4 mission in September, which carried four people on the first all-tourism mission to orbit, where they spent three days.
Jared Isaacman, the commander and financier of the "Inspiration4" mission, as it was called, told CNN Business last month that an alarm went off during the mission, alerting the crew to an unforeseen problem with the toilet's fan. He said he and his fellow passengers had to work with SpaceX controllers on the ground to troubleshoot.
