What to know about 'Plasma gun' technology could transform space laundry and sanitation for future missions

Researchers at the University of Alabama in Huntsville, in collaboration with NASA, are developing a plasma-based 'laundry gun' to sanitize fabrics and equipment for long-duration space missions. The technology uses cold plasma to destroy bacteria without the need for water or traditional chemicals, though it is currently in the prototype stage.

Claim 6: “The electrons in particular collide with other gas molecules such as H2O and O2 to create reactive oxygen species such as O3 and OH.”
VERIFIED
The evidence confirms the general mechanism of plasma chemistry where electrons collide with gas molecules to create reactive species; while the specific O3 and OH mention is a standard chemical result of plasma interacting with O2 and H2O, it is supported by the general physics of the process described in the evidence.
