Chinese rover discovers glass beads on Moon that may contain 330 billion tons of water
AS MUCH AS 330 billion tons of water could be embedded in the Moon’s surface, a new study from China suggests.Get more news about china glass beads,you can vist our website!
The estimate comes from the analysis of small glass beads — also known as impact glasses, spherules or microtektites — uncovered in lunar soil samples collected by Beijing’s Chang’e-5 mission in December 2020.
Each bead is approximately the width of one to several human hairs. There are billions, if not trillions, of such beads scattered across the lunar surface, the study’s researchers told AP News.
The beads form when meteorites of all sizes smash into the Moon at astronomical speeds. The impact heats silicate minerals to melting temperatures, creating the glass spherules.
Researchers say the glass beads are evenly distributed across the lunar surface. Under the right temperatures, they release water into the air, thereby acting as natural reservoirs that are refilled over time.
Extracting water would require mining the beads, heating them and then cooling the released water vapor, according to the researchers.
Future lunar explorations that involve human staffers may benefit from this as they can use the collected water for drinking or as rocket fuel.
“Water is the most sought-after commodity for enabling sustainable exploration of planetary surfaces,” Sen Hu, a planetary geologist at the Chinese Academy of Sciences and one of the study’s co-authors, told Reuters.
“Knowing how water is produced, stored and replenished near the lunar surface would be very useful for future explorers to extract and utilize it for exploration purposes.”
The study, titled “A solar wind-derived water reservoir on the Moon hosted by impact glass beads,” is published in the journal Nature Geoscience.
China discovers strange glass beads on moon that may contain billions of tons of water
Chinese researchers may have discovered billions of tons of water inside strange glass spheres buried on the moon, and they could be used as a future water source for moon bases, a new study suggests. Get more news about china glass beads,you can vist our website!
The tiny glass spherules, collected in lunar soil samples and brought to Earth by China's Chang'e-5 mission in December 2020, could be so abundant that they store up to 330 billion tons (300 billion metric tons) of water across the moon's surface, the new analysis, published March 28 in the journal Nature Geoscience(opens in new tab), shows.
The glass spherules, also known as impact glasses or microtektites, form when meteorites smash into the moon at tens to hundreds of thousands of miles per hour, blasting chunks of lunar crust above the moon's surface. Inside these plumes, silicate minerals heated to molten temperatures by the force of the impact combine to form tiny glass beads that are sprinkled like crumbs over the surrounding landscape.
The moon's soil contains oxygen, which means that the beads do too. When struck with ionized hydrogen atoms (protons) from solar wind, the oxygen in the molten spheres reacts to form water that is sucked inside the silicate capsules. Over time, some of the spheres become buried beneath lunar dust particles, known as regolith, and are trapped underground with the water still inside.
At the right temperatures, some of these beads release the water into the moon's atmosphere and onto its surface, acting as a reservoir that is slowly refilled over time, the researchers said. This could make these spheres an ideal source of water, as well as hydrogen and oxygen, for space agencies like NASA and the China National Space Administration (CNSA) that want to build bases on the moon. The CSNSA expects its moon base project to be completed as soon as 2029.
If we want to extract the water in impact glass beads for future lunar exploration, first we collect them, then boil them in an oven and cool the released water vapor. Finally, you will get some liquid water in a bottle," study co-author Sen Hu(opens in new tab), a planetary geologist at the Chinese Academy of Sciences' Institute of Geology and Geophysics, told Live Science in an email. "Another benefit is that impact glass beads are [common] in lunar soils, from equator to polar and from east to west, globally and evenly."
China's Chang'e 5 mission, named for a Chinese goddess of the moon, was the fifth in a series of missions that aim to lay the groundwork for future human landings on the moon's surface. The mission landed on the moon to scoop material from its surface before returning to Earth in December 2020.
