On Saturday, October 30, astronauts aboard the International Space Station tasted the first-ever chile peppers crop grown in space. Sharing pictures of the space-grown food, NASA astronaut Megan McArthur tweeted, “Finally, I made my best space tacos yet: fajita beef, rehydrated tomatoes, artichokes, and hatch chile!” The chile paper was grown in space as a part of Plant Habitat – 04, NASA’s series of experiments to grow food crops in space, a feat that can make long-duration space missions sustainable. The first picture shows a taco floating near McArthur’s mouth. In a closer look in the second picture, the fillings of the taco can be seen. Among the squishy tomatoes and other fillings, freshly cut green chile peppers stand out. In another picture, McArthur displays her space crop harvest — five chile peppers standing on a floor. The pictures mark the success of the chile pepper’s cultivation experiment, which according to the ISS Research, is “one of the most challenging station plant experiments to date.” After having their ‘space tacos’, astronauts filled out surveys to collect the data of the experiment, McArthur said in her tweet. The chile peppers remaining after astronauts have tasted them will be sent back to earth for further study.
