Japan is researching an artificial gravity facility for the Moon and Mars

Forward-looking: Nations around the world are increasingly thinking about our future in space, and not just jaunts to the Moon and back. Long-term colonies on the lunar surface and Mars are very well within reach but astronauts will need to contend with gravity – or a lack of it – before it becomes viable.

While many would welcome the opportunity to experience the reduced gravitational effects of an environment like the Moon or Mars, research has shown that it can have a negative impact on things like bone strength. We also don't know what sort of impact gravity would play on giving birth in space, or how a child raised in a low gravity environment would handle coming to Earth.

The Moon's gravitational force is about 16.6 percent that of Earth's; on Mars, it's closer to 38 percent of what you experience here on Earth.

To account for the differences, researchers and engineers from Kyoto University and Kajima Construction Co. have proposed an artificial gravity system to support humanity's space life. The residential facility would generate gravity using centrifugal forces.

The cylindrical architecture will measure 100 meters wide and up to 400 meters tall (328 feet wide and 1,312 feet wide). It'll complete a full rotation once every 20 seconds and generate 1G of gravity where the radius is the largest, which is equivalent to what is experienced on Earth.

The team is also thinking about creating core biomes and is even considering a high-speed, interplanetary transportation system that would allow passengers to move between Earth, the Moon and Mars.

Researchers still have plenty of time to hammer out the details and work on funding considering they don't expect colonization efforts to become a reality until the latter half of the 21st century.

"Japan is researching an artificial gravy facility for the Moon and Mars" sounds delicious!

I wonder if anyone has addressed the possibilities of addressing these negative factors through a medical approach? It would appear that using the Krisper (sp?) means of gene manipulation, they could introduce DNA changes that would make the body more tolerable, even resistant to those negative effects and from recent advances in medical science, it could be ready to go much sooner and much less expensive than the Japanese approach, plus it would not require special facilities at each base .....

This is what I'm talking about--transhumanism.

Oh yeah, this is just what we need, trans-GMO people floating in space. Because it's so easy to experiment on human DNA and get the exact modification effects you want without anything negative happening... oh wait.

I don't see the point of the parabolic cone shape. A simple conic shape would be simpler and have more consistent "gravity" locally. If you had an apex, you would feel Moon/Mars gravity only and be spinning at 20 times a second. I think the water would all collect at the big end too. Maybe they want to be able to "walk" out the apex at Moon/Mars gravity? While the idea has merit, the presentation is too artsy and physically impractical.

Of course, no one ever went (back?) to the moon and they're already into a gravity facility... Who pays those "researchers" for projects that are in such a distant/hypothetical future that they wouldn't see nor capitalize on the fruits of their research ?

At least the CG and the concept don't seem that high level and can have been done by beginners.

"Long-term colonies on the lunar surface and Mars are very well within reach"

Wishful thinking...Not for another 100 + years... IF the colonists won't kill each other by then...!
