Japanese Team Invents Moon Base With Artificial Gravity

Getting to the Moon isn’t impossible anymore, but humans have yet to establish a long-term living space on its surface. If we want to become an interplanetary species, however, Japanese researchers say we’ll probably need their newly designed Moon base with artificial gravity.

A team of Kyoto University experts and Kajima Corporation’s construction wizzes unveiled mockups of the conical, rotating structure at a conference last week, showcasing what looks like a glass utopia full of happy people, some of them even driving boats around the water-covered interior of the building.

“Recognizing that ‘1G is the identity of humankind,’ we propose an artificial gravity network,” the team wrote in a Google-translated press statement. “The day when human beings live in outer space, the moon, and Mars is imminent.”

Black Holes are often considered the greatest dangers to spaceships in science fiction, but they may turn out to be the perfect power source for future spaceships.

In order to get into space, we require either huge amounts of rocket fuel or dangerously powerful energy sources, making personal spacecraft a technology limited to science fiction. But by harnessing beamed power sources to run engines, we may be able to create a spaceplane cheap enough and safe enough that anyone could have one in the future.

SpaceX outfits Starship, Super Heavy with dozens of Raptor engines

New photos shared by SpaceX show that the company has nearly finished installing a total of 39 upgraded Raptor engines on a new Starship and its Super Heavy booster.

Those prototypes – known as Ship 24 and Booster 7 – could be tasked with supporting Starship’s first orbital launch attempt sometime later this year if both make it through upcoming test campaigns without major issues. Whether that’s a probable outcome is still uncertain but recent progress suggests that it won’t take long for the prospects of both prototypes to shift into clearer focus.

After several rounds of proof testing and two trips to and from SpaceX’s Starbase, Texas orbital launch site (OLS) in March, April, and May, Super Heavy Booster 7 (B7) made its third trip to the pad on June 23rd.

Cheating Reality

So many of hopes and dreams for colonizing space rely on faster than light travel, and yet the ability to move between stars in moment seems against the laws of reality… but perhaps we can break those rules.

FTL03: Alcubierre Warp Drives

In Episode 3 we look at the concept of warp drives, a theoretical type of spaceship propulsion that warps spacetime to allow faster than light travel. We discuss the basic concept and the scientific and technological hurdles to developing it, along with clearing up many of the myths about it.

Frozen Apollo 17 samples finally analysed after 50 years

View insights.


Scientists are finally getting a look at frozen lunar surface samples from the last time that humans walked on the Moon.

The samples were collected during the Apollo 17 mission, which returned to Earth in December 1972.

As NASA gears up for its Artemis program, which aims to return humans to the Moon by 2024, preserved samples from the later Apollo missions are being studied as part of the Apollo Next Generation Samples Analysis Program (ANGSA). Understanding how different storage techniques and the passage of time have affected lunar samples will inform how NASA will treat new samples collected during Artemis missions.
