Astronauts on the ISS Pick a Second Peck of Chili Peppers


Astronauts on board the Worldwide House Station (ISS) have harvested a second batch of chili peppers grown on the station, bringing to an finish one of the vital complicated experiments in rising vegetation in house thus far.

Though some edible vegetation have been grown on the ISS earlier than, like leafy greens and radishes, the experiment with chili peppers was more difficult than the earlier experiments as a result of the chilies are flowering crops and grew for a complete of 137 days, in comparison with the one or two months most earlier vegetation had been grown for.

The chilies had been grown within the ISS’s Superior Planet Habitat as a part of an experiment known as Plant Habitat-04. “PH-04 pushed the state-of-the-art in house crop manufacturing considerably,” mentioned Matt Romeyn, principal investigator for PH-04 from NASA’s Kennedy House Middle in Florida. “With this experiment, we took a subject cultivar of a Hatch chile pepper from New Mexico, dwarfed it to suit contained in the plant habitat, and found out find out how to productively develop the primary typically acknowledged fruiting crop in house – all in a span of a few years.”

The primary batch of chili peppers was harvested on October 29 and was became tasty tacos for the crew. One of many huge benefits of rising chilies is that their spicy taste is interesting to astronauts, who typically request condiments like sizzling sauce to make their meals extra fascinating.

“The extent of pleasure across the first harvest and the house tacos was unprecedented for us,” Romeyn mentioned. “All indications are among the fruit had been on the spicier aspect, which isn’t surprising, given the unknown impact microgravity might have on the capsaicin ranges of peppers.”

In addition to the bodily well being advantages of contemporary greens, tending to crops after which harvesting and consuming them may be psychologically useful for the astronauts as nicely.

“The largest profit that I’ve seen personally is the impression rising vegetation has on the crew,” mentioned Nicole Dufour, PH-04’s venture supervisor. “They’re so engaged when they’re interacting with the vegetation, particularly when it’s a crop plant just like the peppers. We found the crew had been taking the door shade off day-after-day to examine on the vegetation and have a look at the peppers. That’s not one thing we requested them to do – they only needed to as a result of they loved it a lot.”
