Everyone dreams about what living on some
distant celestial body would be like. The human race has only ever stepped foot
on our moon, though, and it’s not a habitable environment. However, NASA is
looking to change that, starting with growing plants on the lunar surface.
While we’re not even remotely close to having
sci-fi domed habitable zones on anything but Earth, growing plants is a
vital step toward sustainability in a new environment. Aside from the obvious
life support that vegetation would provide — air, food, and water — it would
also provide another integral aspect to a habitable lunar environment. Plants
react to aspects of a harsh environment similarly to humans, as their genetic
material can be damaged by radiation. A relatively safe way to test long-term
lunar exposure is to send some plants up there and monitor their health. NASA
likens this to being like sending a canary into a coal mine. Rather than making the
trip and dropping the plants off itself, NASA plans to use commercial
spaceflight as the vehicle by which the plants will be sent up to the moon.
Obviously, the plants can’t be embedded into
the lunar surface then left alone, so NASA is constructing a small, lightweight
(a little over two pounds), self-sustaining habitat for the vegetation. The
habitat will be delivered to the moon via the Moon Express, a lunar lander
that’s part of the Google Lunar X Prize, a competition to create a robotic
spacecraft that can fly to and land on the moon.
In order to study the quality of the plant
growth and movement, the habitat will take images and beam them back home.
If NASA doesn’t run into any unexpected bumps,
its long-term plans include attempting to grow a more diverse crop of plants,
longer growth periods, and reproduction experiments. The longer the
experiments, the more we’ll learn about the long-term effects of a lunar
environment on Earth plants. Growing turnips on the moon in a man-made pod
won’t directly lead to Luna Park, but its an important step toward a
long-term stay on the lunar surface.
