Artemis II is going so well that we’re left to talk about frozen urine

I don't understand why some efficiency expert hasn't combined both appliances. Just be careful with the plumbing.

On a more serious note... why not put astronauts on a low residue (no poop) diet? 10 days isn't that long.
Go ahead and try it: The resulting gastro issues are (to be careful in phrasing) Challenging.

They did, but they could only produce something not entirely dissimilar to Dutch lager. Still, at least the solid waste is good for fattening up space weevils.

One can get away with “roughing it” when using the bathroom during trips to the Moon. Going to Mars, requiring months in space, is a different matter. If the toilet breaks on the way to Mars, there is a non-zero chance the crew is dying. So it’s great to try out these systems now, on Orion. This really is the purpose of this test flight, to make sure life support systems work for the crew, to identify problems, and to implement fixes in the future.
But I've been assured that the Moon is not a useful stepping stone to Mars!

Things like this are exactly what a shakedown cruise is all about. Identify problem areas and let the engineers get them fixed for the next flight.

I vaguely recall a similar problem on perhaps a Gemini or Apollo mission, and a photo of a yellow tinted icicle sticking out from the dump tube on the side of the capsule.

That's just it. It's not a shakedown cruise, they went full fat around the moon. They're doing LEO testing after this, so lets hope a frozen toilet is the biggest thing on this test flight.

ya if nasa wasn't so strapped for funding they would have launched a full duration mission around the earth like we did with apollo 9

IIRC, there were toilet-related problems on STS with frozen urine dumps attached to the outside of the vehicle.

The term "shakedown cruise" doesn't necessarily mean that operations are limited in scope or duration. It's a nautical term, but it fits the Artemis 2 mission quite well.

Here's a snippet from Wikipedia about shakedown cruises.

"The USS Triton, a nuclear-powered radar picket submarine, was the first vessel to execute a submerged circumnavigation of Earth while on its shakedown cruise in early 1960. Triton is the only U.S. Navy ship to receive a Presidential Unit Citation for its shakedown cruise."

It’s not that NASA didn’t spend enough, it’s that they let their contractors under deliver. If the contractors had spent less time and money on “development” some of those unused resources could have been spent on said additional (safer) testing in Earth orbit.

Maybe they should have more than one toilet for the trip to Mars...
Yes, I recently heard about for the navy that you need three ships to have one operational at all times, (one spare and one being worked on in addition to the one in use), so doing something similar with toilets would be prudent.
