The research project "Environmental response and space utilization of moss plants in space (Space Moss)" by Associate Professor Tomomichi Fujita of Hokkaido University was adopted as a research project using the Japanese Experiment Module "Kibo" of the International Space Station.In the future, we plan to consider a concrete plan with the aim of implementing it within two years.

 Building an ecosystem in outer space and becoming self-sufficient has become an important issue for humankind to advance into outer space.Currently, the water, food, and air necessary for astronauts who stay at the space station for a long time to live are supplied by launching a supply machine from the ground.If this can be covered by an ecosystem starting from plants, the cost of space development can be kept significantly low.It can also be expected to have the effect of relieving the stress of astronauts.However, outer space is a harsh environment even with plants.For example, plants on the ground grow directly above, because they have the property of growing against gravity.From the research so far, it is known that weightlessness extends in any direction.Until now, the response of angiosperms to the space environment has been actively investigated, but in this research, we are investigating how moss grows in space.

 The reasons for using moss are that it grows in a harsh environment even on the ground and that it does not take up space.In addition, in terms of investigating plants that have not been investigated so far, we can expect to obtain clues to clarify the response to the space environment that is common to all plants.The findings obtained in this research will be useful for the development of plants suitable for material production in space, together with the findings obtained in experiments using angiosperms so far.

 If we can cover everything that humans need to live in a small space station, we will be able to stay for a long time without replenishment or move to space.Or the dream of moving to the moon or Mars will come true.

Hokkaido University

Strong cooperation with industry and regions "Practical science unique to Hokkaido University" leads the world

The origin of Hokkaido University dates back to Sapporo Agricultural College, which was established in 1876.Throughout its long history, we have cultivated the basic principles of "frontier spirit," "cultivating internationality," "education for all," and "emphasis on practical studies."Based on this philosophy, he has a high level of academic background that is internationally accepted, and has accurate judgment and a leader […].
