Radishes growing in space: NASA shares time-lapse video covering 27 days in 7 seconds

NASA has shared a beautiful time-lapse video covering 27 days in just 7 seconds of how the radishes grew in the Advanced Plant Habitat (APH) aboard the International Space Station (ISS).
NASA also said that astronaut Kate Rubins harvested the radish plants on November 30, 2020 aboard the ISS.

Rubins collected and wrapped each of the 20 radish plants in foil and placed them in cold storage to preserve them for the return trip to Earth in 2021 on SpaceX’s 22nd Commercial Resupply Services mission.

Plant Habitat-02 (PH-02) is the plant experiment in which NASA for the first time has grown radishes on the ISS. Radishes were chosen for this experiment because they are ready to harvest in 27 days and are well understood by the scientists.

“Radishes are a different kind of crop compared to leafy greens that astronauts previously grew on the space station, or dwarf wheat which was the first crop grown in the APH,” said Nicole Dufour, NASA APH program manager at Kennedy Space Center. “Growing a range of crops helps us determine which plants thrive in microgravity and offer the best variety and nutritional balance for astronauts on long-duration missions.”

The study was led by a professor at the University of Louisiana at Lafayette, Karl Hasenstein, who has carried out plant experiments with NASA since 1995.

“Radishes provide great research possibilities by virtue of their sensitive bulb formation,” Hasenstein said. “We can grow 20 plants in the APH, analyze CO2 effects, and mineral acquisition and distribution.”

Dufour said this historic harvest does not mean the experiment is over.

“The APH has two science carriers, so shortly after the first harvest, the second carrier will be used to repeat the experiment by planting another set of radish seeds,” she said. “Replicating the plant experiment increases the sample size and improves scientific accuracy.”
