Science|NASA’s Latest Breakthrough: ‘Best Space Tacos Yet’
For the archetypal time, astronauts connected the International Space Station cultivated chiles, adding immoderate zing to their tacos.

One tiny measurement for man, 1 elephantine leap for carne asada.
Astronauts aboard the International Space Station person successfully grown and harvested chiles successful space, and this week they enjoyed their spoils for the archetypal time. Megan McArthur, an American astronaut grinning receptor to ear, said connected Twitter that she added the peppers to fajita beef, rehydrated tomatoes and artichokes to make the “best abstraction tacos yet.”
Friday Feasting! After the harvest, we got to sensation reddish and greenish chile. Then we filled retired surveys (got to person the data! 😁). Finally, I made my champion abstraction tacos yet: fajita beef, rehydrated tomatoes & artichokes, and HATCH CHILE! https://t.co/pzvS5A6z5u pic.twitter.com/fJ8yLZuhZS— Megan McArthur (@Astro_Megan) October 29, 2021
Delicious tacos are ever thing to celebrate. But successful this case, they are adjacent much meaningful.
Astronauts devour mostly packaged foods, overmuch of it freeze-dried to trim its size and volume, with immoderate caller nutrient occasionally delivered to the presumption connected regular proviso missions. But a longer travel to Mars, which could instrumentality up to 3 years, would marque receiving caller groceries impossible, and transportation logistics would beryllium hard adjacent connected a shorter travel to the moon.
So increasing nutrient crops successful abstraction is seen arsenic a important situation to overcome, allowing astronauts to supplement their diets. Last year, NASA announced that lettuce grown successful space was harmless to devour and arsenic nutritious arsenic that grown connected Earth. But chiles person been much hard to grow; NASA described the experimentation arsenic “one of the astir analyzable to day connected presumption due to the fact that of the agelong germination and increasing times.”
There are additional benefits to increasing chiles. Astronauts who don’t similar the sensation of their nutrient whitethorn devour less, perchance starring to wellness issues. Adding immoderate spice could improve morale and trim fatigue with the constricted culinary options available.
Because fluids travel to the caput successful a weightless environment, galore astronauts go congested and crave spicy foods. Some person brought on blistery sauce.
NASA researchers spent 2 years seeking retired the cleanable capsicum to grow, evaluating much than 2 twelve options. They settled connected the Hatch chile from Hatch, N.M., which has a standing of 2,000 to 4,000 Scoville Heat Units, astir the level of Tabasco sauce. (Much similar sparkling vino produced extracurricular Champagne, France, the peppers grown connected the abstraction presumption are not technically Hatch peppers, since they were grown extracurricular the Hatch Valley.)
Though astronauts person been increasing plants successful abstraction for decades, cultivating edible nutrient without the benefits of gravity and earthy airy has been difficult. Veggie, a enclosure that has been utilized to turn lettuce and different plants connected the abstraction presumption since 2014, nurtures the plants successful a porous ceramic clay alternatively of ungraded and uses wicks to usher h2o to the roots.
A NASA squad planted 48 capsicum seeds connected Earth with a fertilizer specifically designed for peppers and sent them to the abstraction presumption connected a SpaceX cargo resupply mission. In July, astronauts began watering them and pollinating immoderate of the flowers; a fewer of the plants developed fruit, which was harvested for the tacos and volition beryllium again successful November, NASA said.
