NEW: Artemis II Commander Reid Wiseman reveals some of the issues the crew had with the spacecraft's toilet during their historic spaceflight:"You know, when you go to the bathroom, at the end of doing that, you flush the toilet? The toilet flushed just fine. But then when the liquid went out the bottom of the toilet, it got clogged up in our vent line.""For those great engineers that made that toilet, I don't want them hanging their head low. They should hang it very high."
