Japan begins exploration of places on the Moon and Mars for humans


Researchers from Kyoto University and construction company Kajima Corp. presented plans to construct housing complexes needed for human habitation on the Moon and Mars, as well as a transportation system reminiscent of a Galaxy Express.

“There is no such plan in other countries’ space development plans,” Yosuke Yamashiki, director of Kyoto University’s SIC Human Spaceology Center, said at a July 5 news conference at the university.

“Our plan represents important technologies that are critical to enabling humans to travel to space in the future.”

They announced that they will conduct a joint study to bring the plan to fruition.

However, the plan will not be possible until the 22nd century at the earliest.

Central to the plan is the construction of “artificial gravity housing complexes”.

The facilities will be able to generate the same gravity as on Earth, using the centrifugal force generated by rotational motion.

One such facility, called Lunar Glass, is to be built on the moon as part of the plan.

Another called Mars Glass is being built on Mars.

Gravity on the Moon and Mars are respectively one sixth and one third of Earth’s gravity.

The facilities will help reduce the health impacts on people on the Moon or Mars that could be caused by low gravity, according to the researchers.

They also plan to make room in the condominiums, complete with forests or waterfront promenades, mimicking those biodiversity on earth.

Though they expect the giant facilities to take about 100 years to build, they want to build a simplified version of it on the moon by 2050.

The plan also includes building a transportation system called the Hexagon Space Track System, reminiscent of a Galaxy Express, to travel between the Earth, Moon and Mars.

The system’s space train, the size of a Shinkansen, will also generate artificial gravity and travel like trains traveling on Earth, according to the researchers.

It will stop at “stations” being built on satellites orbiting the Earth, Moon or Mars.

Linear motors or rocket engines are used to launch it when it leaves the moon or Mars.

Each car of the train is separated at the stations and transported in hexagonal pods when traveling between planets to avoid exposure to cosmic rays.

“As the idea of ​​living in space becomes more realistic, we need to overcome the low-gravity problem that I intuitively became aware of as a child,” said Takuya Ono, associate project professor at the center and a senior researcher at Kajima, a large general contractor.

“We are committed to bringing the plan to fruition so that it will be of use to the people.”
