Having a discussion today on some odor control challenges with the Orion toilet. No febreeze, glade, or candles allowed.
If you want to recreate that used spacecraft smell, take a couple dirty diapers, some microwave food wrappers, a used airsickness bag, & a few sweaty towels, put them in an old school metal trash can and let it bake in the summer sun for 10 days. Then open the kid & breathe deep
Pity the first ground crew member to open that hatch. Flight crew can be desensitized to it a bit as the stank gradually increases through the mission.
Our toilet and trash bags are designed with odor control features but breakthrough will occur after some amount of time.
The unsung heroes of the space program are the certified sniffers at White Sands who get to verify the odor control features work correctly.
