Artemis II: Space Toilet sorted out for now

 

The Artemis II space toilet, known as the Universal Waste Management System (UWMS), is a compact, titanium-based vacuum commode on the Orion capsule, designed for 10-day deep-space missions. 

It uses airflow to direct waste, separates urine (vented overboard) from feces (stored), and provides privacy behind a door. 

It recently overcame a fan malfunction early in the mission. 

It is understood that the toilet originally built by  Howard Wolowitz, for the space station, is now on the Artemis II moonshot. 

Wolowitz received his Master of Engineering degree from the Massachusetts Institute of Technology (MIT), which led him to become an aerospace engineer.

The Key Features and Functionality of the Space Toilet, otherwise known as Woloowitz. As the problem occurred, it is reported that a number of the team said "not another Wolowitz!!"

Not helped that Wolowiz had to design a smaller, more efficient version of the toilet used on the International Space Station (ISS).

The operation of the Wolowitz is a hose with a funnel that collects urine, while a seat collects solid waste; both use suction (vacuum) to manage waste in low gravity.

Perhaps for the better, the waste management system is unlike the ISS, which recycles urine into water; the Artemis II system vents urine overboard. While the fecal waste is stored in a container equipped with filters for odor and gas control.

Privacy & Structure: The toilet is located behind a folding door in the 330-cubic-foot capsule for crew privacy. 

The initial Issue: shortly after launch, the system experienced a jammed fan, which the crew fixed, ensuring continued operation. 

Wolowitz,  humiliated, insisted the flaw was caused by ignoring his warnings about a "heavy potato-based diet". 

There is only one toilet on the Artekis - so quite important that it works!! The contingency plan is it fails is would have the mission using "collapsible contingency urinals" and bags for waste collection.
