Chile pepper plants growing in the Advanced Plant Habitat (APH) aboard the International Space Station recently bore fruit. The peppers developed from flowers that bloomed over the past few weeks. Studies of fruit development in microgravity are limited, but overcoming the challenges of growing fruit in microgravity is important to NASA for long-duration missions during which crew members will need good sources of Vitamin C to supplement their diets.

A view of radishes growing in the Advanced Plant Habitat (APH) ground unit inside the Space Station Processing Facility at NASA’s Kennedy Space Center in Florida on Dec. 14, 2020. The radishes are a ground control crop for the Plant Habitat-02 (PH-02) experiment. The experiment also involves growing two similar radish crops inside the International Space Station’s APH. NASA astronaut Kate Rubins harvested the first crop on Nov. 30, and the second harvest aboard the orbiting laboratory is planned for Dec. 30. Once samples return to Earth, researchers will compare those grown in space to the radishes grown here on Earth to better understand how microgravity affects plant growth.

A researcher from NASA’s Kennedy Space Center in Florida prepares pepper seeds for planting inside science carriers on April 8, 2021, inside the Space Life Sciences Lab for the Plant Habitat-04 (PH-04) experiment. The seeds will fly to the International Space Station on SpaceX’s 22nd Commercial Resupply Services (CRS-22) mission. When the experiment starts, astronauts will grow the pepper seeds in the Advanced Plant Habitat (APH) growth chamber, which will monitor the experiment with more than 180 sensors. The astronauts will observe plant growth for about four months and conduct two harvests to study whether microgravity affects growth, flavor, or texture. Since peppers take longer to germinate, grow, and develop than previous crops grown in space, the PH-04 experiment also will test the durability and reliability of the various systems within the APH.
