Interest in the Moon has been revived Recently, and Japan is looking to join in the fun. Researchers and engineers from Kyoto University and the Kajima Corporation has published its joint proposal for a three-pronged approach to sustainability human life on the moon and beyond.

The future of space exploration will likely include longer stays in low-gravity environments, either in orbit or on the surface of another planet. the problem is, meLong stays in space can wreak havoc on our physiology; recent research shows that astronauts can suffer a decade of bone loss during months in space, with their bones never returning to normal. Fortunately, researchers at Kyoto University and the Kajima Corporation are looking to devise a possible solution.

The proposal announced in a Press release last week, it looks like something ripped straight from the pages of a science fiction novel. The plan consists of three distinct elements, the first of which, He called the glass,” aims to bring simulated gravity to the Moon and Mars through centrifugal force.


Gravity on the Moon and Mars it is about 16.5% and 37.9% of that of Earth, respectively. Lunar Glass and Mars Glass could bridge that gap; they are massive spinning cones that will use centrifugal force to simulate the effects of Earth’s gravity. These spinning cones will have an approximate radius of 328 feet (100 meters) and a height of 1,312 feet (400 meters), and will complete one rotation every 20 seconds, creating a 1g experience for those inside (1g being gravity). on earth). The researchers are targeting the second half of the 21st century for the construction of Lunar Glass, which seems unreasonably optimistic given the apparent technological expertise required to pull it off.

The second element of the plan is the “core biome complex” to “relocate a reduced ecosystem in space,” according to a Google-translated version of the press release. The core biome complex would exist within Moon Glass/Mars Glass structure and is where human explorers would live, according to the proposal. TThe final element of the proposal is the “Hexagon Space Track”, or Hexatrack, a high-speed transportation infrastructure that could connect Earth, Mars and the Moon. Hexatrack will require at least three different stations, one on Mars’ moon Phobos, one in Earth orbit, and one around the Moon (probably the one planned). Moon Gate).

The trip back to the Moon is getting closer while the interest in settling down Mars is growing. A major obstacle standing in the way of long-term permanence in these bodies is gravity. The Kyoto University and Kajima Corporation proposal is exciting and promising, but not something we should expect anytime soon.
