French astronaut Thomas Pesquet shared a video showing five green peppers that were successfully grown and cultivated aboard the International Space Station as part of NASA’s Plant Habitat-04 investigation.

"Finally harvesting the peppers after watching them grow for so many months. It’s nice to have some locally grown produce, however …" Pesquet wrote alongside his video, finishing his tweet with the pepper emoji and four fire emojis, suggesting that the locally grown peppers were on the spicy side.

The peppers took roughly four months to grow and researchers spent several years selecting the perfect pepper variety, eventually settling on the hatch chile pepper, hailing from southern New Mexico.

Nasa Astronaut Megan McArthur also tweeted about the space harvest, saying she had made her "best tacos yet".

"Growing colorful vegetables in space can have long-term benefits for physical and psychological health," Matt Romeyn, principal investigator for NASA’s Plant Habitat-04 investigation said.

"We are discovering that growing plants and vegetables with colors and smells helps to improve astronauts’ well-being," Romeyn went on.

LaShelle Spencer, PH-04’s project science team lead says nutritious and tasty foods will be essential to sending people to Mars and back.

"The food astronauts eat needs to be as good as the rest of their equipment. To successfully send people to Mars and bring them back to Earth, we will not only require the most nutritious foods, but the best tasting ones as well."
