[O08-P43] High Performance Martian Soil "Artemis program"
Keywords:Martian, soil
Abstract
With the recent development of the space industry, self-sufficiency of food will be
required in space. Therefore, our goal is to turn Martian "sediment" into nutritious "soil"
in which plants can grow. In order to efficiently transform "sediment" into "soil," we
focused on high-performance soil. This is a technology that can turn sediment into soil
through the appropriate use of microorganisms and organic matter. We developed our
own high-performance soil using Martian soil, and conducted a "colony count survey"
using agar culture to confirm whether the high-performance soil actually worked.
Background and Purpose of the Research
Now that the scale of the space industry is expanding, it is assumed that mankind will
develop the space industry, starting with the Artemis Project. Food is essential for
humans to operate in space, and an efficient way to acquire food is local procurement.
Therefore, we determined that there is a demand for sustainable plant cultivation on
Mars, and conducted this research with the objective of contributing to the space
industry in the future.
Methods
(1) Prepare basalt soil with and without alfalfa, and add microorganisms.
(2) After one week, take a little of each soil and soak it in water on a petri dish.
(3) Remove the liquid from the petri dish and apply it to the agar medium.
(4) Make five of each and see how the microbial colonies grow after one week
Result
As shown in the table, microorganisms grew more in the planter mixed with alfalfa
than in the planter without alfalfa. Conversely, planters without alfalfa have fewer
microorganisms, reading the environment as unsuitable for microbial activity.
("without alfalfa" is simulated regolith with microorganisms added).
Discussion and Conclusion
We have succeeded in visualizing the microbial activity of alfalfa and agar cultures,
and have obtained data on the microbial activity of alfalfa and agar cultures.
In conclusion of this study, based on scientific data, we prove that we have developed
a highly functional soil made of Martian sediment by measuring the number of colonies
in agar culture.
