In the 2015 sci-fi movie The Martian, Matt Damon stars as an astronaut who survives on a weight loss program of potatoes cultivated in human feces whereas marooned on the Red Planet.
Now a New York firm that makes carbon-negative aviation gasoline is taking the menu for interplanetary delicacies in a really completely different route. Its innovation has put it within the finals of a NASA-sponsored contest to encourage improvement of next-generation applied sciences for assembly the food wants of astronauts.
Closely held Air Company of Brooklyn has pioneered a approach of recycling carbon dioxide exhaled by astronauts in flight to develop yeast-based vitamins for protein shakes designed to nourish crews on long-duration deep-space missions.

“It’s definitely more nutritious than Tang,” mentioned firm co-founder and Chief Technology Officer Stafford Sheehan, referring to the powdered beverage popularized in 1962 by John Glenn when he grew to become the primary American to orbit Earth.
Sheehan, who has a doctorate in bodily chemistry from Yale University, mentioned he initially developed his carbon-conversion expertise as a method of manufacturing high-purity alcohols for jet gasoline, fragrance and vodka.
The NASA-sponsored Deep Space Food Challenge prompted Sheehan to modify his invention as a approach of manufacturing edible proteins, carbohydrates and fat from the identical system.
Tastes like…Seitan
The ensuing single-cell protein drink entered in NASA’s contest has the consistency of a whey protein shake, Sheehan mentioned. Sheehan in contrast its taste with that of seitan, a tofu-like food made out of wheat gluten that originated in East Asian delicacies and has been adopted by vegetarians as a meat substitute.
“And you get that sweet-tasting, almost malted flavor to it,” Sheehan mentioned in an interview.
Apart from protein drinks, the identical course of can be utilized to create extra carbohydrate-heavy substitutes for breads, pastas and tortillas. For the sake of culinary selection, Sheehan mentioned he sees his smoothie being supplemented on missions by different sustainably produced comestibles.
The firm’s patented AIRMADE expertise was certainly one of eight winners introduced by NASA this month within the second section of its food competitors, alongside with $750,000 in prize cash. A ultimate spherical of the competitors is coming up.
Other winners included: a bioregenerative system from a Florida lab to elevate recent greens, mushrooms and even insect larvae to be used as micronutrients; a synthetic photosynthesis course of developed in California to create plant- and fungal-based elements; and a gas-fermentation expertise from Finland to produce single-celled proteins.

Up to $1.5 million in prize cash will likely be divvied up among the many eventual ultimate winners of the competition.
While few if any are seemingly to earn a spot within the Michelin Guide for wonderful eating, they signify a giant leap ahead from Tang and the freeze-dried snacks consumed by astronauts within the earliest days of space journey.
The new food-growing schemes are additionally extra appetizing, and promise to be much more nutritious, than Matt Damon’s fictional poop-fertilized potatoes in The Martian.
“That was taking an idea to an extreme for a Hollywood movie,” mentioned Ralph Fritsche, space crop production supervisor at NASA’s Kennedy Space Center in Florida, including that human waste alone “is not the complete nutrient source that plants need to grow and thrive.”
Keeping astronauts properly nourished for prolonged durations inside the restricted, zero-gravity confines of space automobiles in low-Earth orbit lengthy has posed a problem for NASA. For the previous 20 years, crews aboard the International Space Station have lived on a weight loss program principally of packaged meals with some recent produce delivered on common re-supply missions.
ISS groups even have experimented with rising a lot of greens in orbit, together with lettuce, cabbage, kale and chile peppers, in accordance to NASA.

But the crucial for self-contained, low-waste food production requiring minimal sources has turn out to be extra pronounced as NASA units its sights on returning astronauts to the moon and eventual human exploration of Mars and past.
Advances in space-based food production even have direct purposes for feeding Earth’s ever-growing inhabitants in an period when local weather change is making food extra scarce and tougher to produce, Fritsche mentioned.
“Controlled environment agriculture, the first modules we deploy on the moon, will have some similarity to the vertical farms that we’ll have here on Earth,” Fritsche mentioned.
Sheehan’s system begins by taking carbon dioxide gasoline scrubbed from the air breathed by astronauts and mixing it with hydrogen gasoline extracted from water by electrolysis. The ensuing alcohol-and-water combination is then fed right into a small amount of yeast to develop a renewable provide of single-celled proteins and different vitamins.
In essence, Sheehan mentioned, the carbon dioxide and hydrogen kind an alcohol feedstock for the yeast, “and the yeast is the food for the humans.”
“We’re not re-inventing products,” Sheehan mentioned, “we’re just making them in a more sustainable way.”
