Can Solar Wind Make Water on the Moon? A NASA Experiment Shows Maybe

3 months 2 weeks ago
"Future moon astronauts may find water more accessible than previously thought," writes Space.com, citing a new NASA-led experiment: Because the moon lacks a magnetic field like Earth's, the barren lunar surface is constantly bombarded by energetic particles from the sun... Li Hsia Yeo, a planetary scientist at NASA's Goddard Space Flight Center in Maryland, led a lab experiment observing the effects of simulated solar wind on two samples of loose regolith brought to Earth by the Apollo 17 mission... To mimic conditions on the moon, the researchers built a custom apparatus that included a vacuum chamber, where the samples were placed, and a tiny particle accelerator, which the scientists used to bombard the samples with hydrogen ions for several days. "The exciting thing here is that with only lunar soil and a basic ingredient from the sun — which is always spitting out hydrogen — there's a possibility of creating water," Yeo said in a statement. "That's incredible to think about." Supporting this idea, observations from previous moon missions have revealed an abundance of hydrogen gas in the moon's tenuous atmosphere. Scientists suspect that solar-wind-driven heating facilitates the combination of hydrogen atoms on the surface into hydrogen gas, which then escapes into space. This process also has a surprising upside, the new study suggests. Leftover oxygen atoms are free to bond with new hydrogen atoms formed by repeated bombardment of the solar wind, prepping the moon for more water formation on a renewable basis. The findings could help assess how sustainable water on the moon is, as the sought-after resource is crucial for both life support and as propellant for rockets. The team's study was published in March in the journal JGR Planets . NASA created a fascinating animation showing how water is released from the Moon during meteor showers. (In 2016 scientists discovered that when speck of comet debris vaporize on impact, they create shock waves in the lunar soil which can sometimes breach the dry upper layer, releasing water molecules from the hydrated layer below...)

'Read the Manual': Misconfigured Google Analytics Led to a Data Breach Affecting 4.7M

Slashdot reader itwbennett writes: Personal health information on 4.7 million Blue Shield California subscribers was unintentionally shared between Google Analytics and Google Ads between April 2021 and January 2025 due to a misconfiguration error. Security consultant and SANS Institute instructor Brandon Evans points to two lessons to take from this debacle: Read the documentation of any third party service you sign up for, to understand the security and privacy controls;Know what data is being collected from your organization, and what you don't want shared. "If there is a concern by the organization that Google Ads would use this information, they should really consider whether or not they should be using a platform like Google Analytics in the first place," Evans says in the article. "Because from a technical perspective, there is nothing stopping Google from sharing the information across its platform... "Google definitely gives you a great bunch of controls, but technically speaking, that data is within the walls of that organization, and it's impossible to know from the outside how that data is being used."
