The last time the International Space Station got a new toilet was back in the early 1990s, so it’s due for this $23 million titanium upgrade. The last one didn’t consider the physical differences in how men and women go to the bathroom. It’s not as easy to just go when you’re in orbit—kind of like when you try to make dinner right after you move. Nothing’s in the right box and doing the most straightforward thing takes forever. Or like camping. But in this case, the stakes if you mess up are much higher. “Cleaning up a mess is a big deal,” said Melissa McKinley, the Space Center project manager for the toilet payload, “We don’t want any misses or escapes.” She’s discreetly referring to what can happen when you go to the bathroom without gravity.
