  • Why Do We Grow Plants in Space? We Asked a NASA Expert

    Why Do We Grow Plants in Space? We Asked a NASA Expert

    Plants are more than just greenery, they’re key to helping astronauts survive and thrive off Earth. They provide food and oxygen, recycle water and waste, and even offer psychological benefits.

    But the positives don’t stop there. Growing plants in the International Space Station also helps scientists develop new technologies for agriculture in extreme environments, a skill that could benefit future explorers on the Moon and Mars but also agriculture right here on Earth, especially in places where growing food is a challenge.

    A NASA scientist explains why space farming is so important for both space exploration and life on our own planet. Learn more about growing plants in space: https://www.nasa.gov/exploration-research-and-technology/growing-plants-in-space/

    Electrical experiments with plants that count and communicate | Greg Gage

    Neuroscientist Greg Gage takes sophisticated equipment used to study the brain out of graduate-level labs and brings them to middle- and high-school classrooms (and, sometimes, to the TED stage.) Prepare to be amazed as he hooks up the Mimosa pudica, a plant whose leaves close when touched, and the Venus flytrap to an EKG to show us how plants use electrical signals to convey information, prompt movement and even count.

    Plants in space

    Growing plants for food was a significant step in the history of mankind. Growing plants for food in space and on other planets will be necessary for exploration of our Universe.

    Javier Medina from the Spanish research council CSIC explains the attraction of plants for human exploration to supply oxygen and food.

    He introduces current and future experiments on the International Space Station into plants and explains the logic of these greenhouses in space.

    Sometimes, gardening and planting seeds can be very boring. This can especially be the case if you are a young scientist that loves action and excitement! Thankfully, there are gardening methods that can offer a bit more kick than just digging holes and planting. Introducing Seed Balls, the method of gardening that allows you to throw to sow!
