Tiny Orange Beads Found By Apollo Astronauts Reveal Moon's Volcanic Past

22 juin 2025 à 16:34
"When Apollo astronauts stumbled across shimmering orange beads on the moon, they had no idea they were gazing at ancient relics of violent volcanic activity," writes ScienceDaily. These glass spheres, tiny yet mesmerizing, formed billions of years ago during fiery eruptions that launched molten droplets skyward, instantly freezing in space. Now, using advanced instruments that didn't exist in the 1970s, scientists have examined the beads in unprecedented detail. The result is a remarkable window into the moon's dynamic geological history, revealing how eruption styles evolved and how lunar conditions once mirrored explosive events we see on Earth today... Analyses of orange and black lunar beads have shown that the style of volcanic eruptions changed over time. "It's like reading the journal of an ancient lunar volcanologist," said Ryan Ogliore [an associate professor of physics at Missouri's Washington University, which has a large repository of lunar samples that were returned to Earth]. "The beads are tiny, pristine capsules of the lunar interior..." says Ogliore. "We've had these samples for 50 years, but we now have the technology to fully understand them..." "The very existence of these beads tells us the moon had explosive eruptions, something like the fire fountains you can see in Hawaii today."

Japan-based Ispace confirmed its Resilience lander likely crashed during its second failed attempt at a lunar landing, after a sensor malfunction prevented proper deceleration. Despite the setback, the company remains committed to future missions, with funding secured for a third attempt using a new lander, Apex 1.0, scheduled for 2027. "Until then, Ispace has its work cut out for it," reports CNN. "[Ispace CEO and founder Takeshi Hakamada] said during the news briefing he will need to work to regain the trust of investors, and the company will need to deeply investigate what went wrong on the Resilience mission to ensure similar issues don't plague Apex 1.0." The company has ambitious "plans to eventually build a city on the lunar surface that would house a thousand people and welcome thousands more for tourist visits," notes ABC News. "If ispace is going to establish a colony on the moon, it will need to identify an ample supply of ice or water, which it will convert into fuel for a future lunar fueling station. The ability to produce fuel on the moon will enable the company to transport people back and forth between the Earth and the moon."
