A major breakthrough in science as NASA astronauts successfully grow radishes onboard a microgravity chamber in the International Space Station (ISS).
In late November, astronaut Kate Rubins onboard the ISS shared images of the 20 radish plants she had grown in the ISS’ Advanced Plant Habitat.
The radish harvest was part of NASA’s plant experiment, Plant Habitat-02 (PH-02) that seeks to understand how plants grow in microgravity conditions.
Radishes were chosen since they are fairly well understood by scientists and achieve maturity in just 27 days. Radishes are also edible and nutritious, with this batch ready for harvest any day now. Samples will be sent back to Earth for study.
Because plants no longer have gravity to root them in the soil, the seeds are grown in ‘pillows’ that help evenly distribute fertilizer and water to the roots.
