These could be incredibly valuable to future astronauts hoping to settle on the moon, acting as a convenient shelter for a lunar base.

The cave is accessible through a pit in the well-studied Mare Tranquillitatis (Sea of Tranquility). This is a large basin made mostly of basalt. Neil Armstrong and Buzz Aldrin touched down in this region on July 20 1969.

While Mare Tranquillitatis isn’t likely to be the first place humans try to settle on the moon, the existence of one cave makes the existence of others very likely, so scientists now expect there to be others in locations more suitable for human settlement.

A new study provides evidence that Mars contains a large ocean deep beneath its surface.

The finding is based on data collected by the InSight Lander, a robotic explorer operated by the American space agency NASA. InSight, which landed in 2018, was designed to capture data from within the planet’s interior. The lander ended its operations on Mars in late 2022.

For the current study, researchers used seismic data collected by InSight. The team examined the data to study Martian quake activity. Seismic activity on Mars happens in the form of “marsquakes.” NASA says InSight had recorded more than 1,300 marsquakes.

A new theory suggests time travel might be possible without creating paradoxes.

TL;DR:

A physics student from the University of Queensland, Germain Tobar, has developed a groundbreaking theory that could make time travel possible without creating paradoxes. Tobar’s calculations suggest that space-time can adjust itself to avoid inconsistencies, meaning that even if a time traveler were to change the past, the universe would correct itself to prevent any disruptions to the timeline. This theory offers a new perspective on time loops and free will, aligning with Einstein’s predictions. While the math is sound, actual time travel remains a distant possibility.

Following NASA ’s DART mission, which successfully tested asteroid deflection techniques by colliding with the moonlet Dimorphos, extensive research has revealed insights into the geological features and evolutionary history of the Didymos asteroid system.

Studies have characterized the surface and interior of these celestial bodies, examined their formation processes, and assessed their response to impacts. These findings not only provide a clearer understanding of binary asteroid systems but also enhance planetary defense strategies.

In the months that followed NASA’s Double Asteroid Redirection Test (DART) mission, which sent a spacecraft to intentionally collide with an asteroid moonlet, the science team verified that kinetic impact was a viable deflection technique, proving one effective method of preventing future asteroid strikes on Earth.

WASHINGTON — U.S. Space Command’s top general voiced support for the U.S. Army’s efforts to expand its space expertise, pushing back against criticism that such initiatives encroach on Space Force territory. Gen. Stephen Whiting, commander of U.S.

Right off the bat, one of the biggest improvements is the weight of the 4,680 shell itself – down to 49g from the 70g weight of a gen 1 cell. Tesla has essentially optimized the shell, making it thinner, and reducing its internal complexity. They do this by welding the tabless electrode to the cell cap.

That weight reduction is significant – at the battery pack level, the Cybertruck has 1,344 cells – which means that it reduces 28.2kg or 62.1lb of the overall pack weight. But rather than leaving that space empty, Tesla has instead filled that weight with more battery material. Calculated, that’s about a 10% increase in overall pack energy density.

The Limiting Factor intends to release another video looking at the energy density of the Cybercell and the detailed specs of the 4,680 cell. We’ll be on the lookout for both of those videos in the coming weeks as they could reveal additional information on Tesla’s 4,680 Gen 2 cells. We’re interested in how the Cybercell shapes up in comparison to the previous 4,680 cells – which were pulled from production after the 4680 Model Y.
