  • Japanese researchers have released plans to recreate Earth's level of gravity on the moon.
  • 2
  • The effort aims to support plans by the United States and other nations to establish long-term bases for humans on the moon.
  • 3
  • The low gravity on the moon would affect humans living there in important ways.
  • 4
  • The American space agency NASA notes that gravity on the surface of the moon is one-sixth the gravity we experience on Earth.
  • 5
  • Designers working on plans to recreate Earth's level of gravity, known as "1 g," on the moon are proposing the use of a centrifugal system.
  • 6
  • Centrifugal force is created by circular motion.
  • 7
  • A centrifuge machine turns very fast to force material in it away from a center or axis point, NASA explains.
  • 8
  • This planned system would create artificial gravity within an enclosed space on the moon's surface.
  • 9
  • The project is a partnership between researchers at Japan's Kyoto University and engineers at Japanese building company Kajima.
  • 10
  • The researchers said a centrifugal system could also work on Mars.
  • 11
  • The two organizations recently announced they will launch a joint study on developing the living environments.
  • 12
  • "Humanity is now moving from the era of 'staying' in space to the era of 'living' on the Moon and Mars,"
  • 13
  • said a statement issued by Kyoto University's SIC Human Spaceology Center.
  • 14
  • The researchers said they plan to "develop an infrastructure" to support human life on the moon and Mars.
  • 15
  • This would involve building "artificial gravity habitats" in both places.
  • 16
  • The huge, planned structures will be designed with living spaces, as well as small forests and waterfronts.
  • 17
  • The team is calling its moon project Lunar Glass. It says a simplified version of the structure could be built on the moon by 2050.
  • 18
  • Yosuke Yamashiki is the director of the SIC Human Spaceology Center.
  • 19
  • He told Japan's Asahi Shimbun newspaper, "There is no plan like this in other countries' space development plans."
  • 20
  • Yamashiki added that the plan "represents important technologies" that will permit humans to move to space for long periods.
  • 21
  • The American space agency NASA plans on returning humans to the moon as early as 2025 as part of its Artemis program.
  • 22
  • The program also calls for establishing a long-term base on the moon that could one day launch astronauts to Mars.
  • 23
  • Last year, China and Russia signed an agreement to set up an international lunar research station on the surface of the moon.
  • 24
  • And American billionaire and SpaceX chief Elon Musk has said he wants to launch humans to Mars on his company's rockets by 2030.
  • 25
  • The Japanese researchers say one of the main purposes of the artificial gravity environments is to permit people to stay on the moon or Mars without suffering bad physical effects.
  • 26
  • Several studies have shown that the human body can be harmed by the lack of gravity in space.
  • 27
  • The team said in a statement that an artificial gravity environment could make it possible for humans to give birth on places like the moon or Mars.
  • 28
  • In addition, children could develop and grow normally.
  • 29
  • The researchers note, however, that much study and testing will be needed to identify the true health benefits of artificial gravity in space.
  • 30
  • By living in such environments, "human beings will be able to have children without anxiety and maintain a physical condition that allows them to return to Earth at any time," the researchers said.
  • 31
  • Another part of the project involves plans to build a transportation system to travel between Earth, the moon and Mars.
  • 32
  • The so-called "Hexagon Space Track" would use the same artificial gravity technology as the proposed structures, the researchers said.
  • 33
  • The system would be designed to permit vehicles to stop at "stations" - built on satellites - orbiting the moon or Mars.
