Successful trial planting of soil crops in lunar soil Next step: Trial planting on the moon

Scientists began planting plants such as Thale cress in the lunar soil collected by Apollo 11 and other spacecraft in 1969 to study whether it was possible to grow terrestrial plants on the Moon’s surface to provide food and oxygen. Or not. The news is that all the seeds have germinated, but the lunar soil is “poor” and most plants are lethargic and dwarf compared to Earth’s crops.

Associated Press reported on the 11th that scientists conducted experiments and sowed seedsAstronautWhen the soil was brought back from the Moon, it was impossible to imagine that plants would take root and sprout on it.


A research team from the Institute of Food and Agricultural Sciences at the University of Florida found that every seed germinated, and team member Robert Farrell exclaimed with surprise and excitement, “Plants actually evolved from lunar soil, no joke!”

However, since lunar soil is rough and dry, after a week, the newly sprouted Arabidopsis thaliana struggled to grow. Compared to the same batch of seeds planted in Moon soil imaged Earth’s soil, growth was slow and small. and smaller.

The researchers published the test results on 12th in the journal Communications Biology.

Lunar soil is subject to cosmic radiation and the SunStormlonger time, less conducive to plant growth; The lunar calm sea surface soil brought back by astronauts like Armstrong has been on the lunar surface for 2 billion years before collection, and scientists say it is very unfavorable for plant growth.

At least finding that plants can be grown is a big step, said Simon Gilroy, a space plant biologist on the University of Wisconsin-Madison campus. “The next step is to attempt planting directly on the Moon.” this study.

Moon dust is filled with fine glass fragments caused by collisions with meteorites, and the clothes of the Apollo lunar landers and astronauts are covered in this clay dust. Improved “moon soils” can be excavated from the riverbed of volcanic lava flows, and planting environments can be corrected, such as adding plant nutrients or replacing natural light with artificial light.

The six Apollo astronauts brought back a total of 842 pounds (382 kilograms) of lunar rocks and soil; These precious lunar rocks and soil should not be shown to the outside world, NASA (NASA) At the beginning of last year, 12 grams were specially allocated to researchers from Buddha University, and the experimental planting of lunar soil began only in May last year. NASA said that the experiment is just starting because in a few years the space agency will send people again to the moon.
