BLiSS, developed at NASA's Kennedy facility, processes human waste and wastewater using high-tech reactors and processors.
It produces a nutrient-rich effluent containing plant-essential nutrients.

By enriching lunar and Martian regolith simulants with nutrients such as sulfur and calcium, BLiSS could help future space travelers grow their own food far from Earth.
That means longer missions (and maybe even living on the Moon or Mars) could actually be possible someday.
