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

2 weeks 5 days 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

2 weeks 5 days ago
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."

YouTube is Huge - and a Few Creators Are Getting Rich

2 weeks 5 days ago
"Google-owned YouTube's revenue last year was estimated to be $54.2 billion," reports the Los Angeles Times, "which would make it the second-largest media company behind Walt Disney Co., according to a recent report from research firm MoffettNathanson, which called YouTube 'the new king of all media.'" YouTube, run by Chief Executive Neal Mohan since 2023, accounted for 12% of U.S. TV viewing in March, more than other rival streaming platforms including Netflix and Tubi, according to Nielsen... More people are watching YouTube on TV sets rather than on smartphones and computer screens, consuming more than 1 billion hours on average of YouTube content on TV daily, the company said on its website. When YouTube first started its founders envisioned it as a dating site, according to the article, "where people would upload videos and score them. When that didn't work, the founders decided to open up the platform for all sorts of videos." And since this was 20 years ago, "Users drove traffic to YouTube by sharing videos on MySpace." But the article includes stories of people getting rich through YouTube's sharing of ad revenue: Patrick Starrr, who produces makeup tutorial videos, said he made his first $1 million through YouTube at the age of 25. He left his job at retailer MAC Cosmetics in Florida and moved to L.A... [Video creator Dhar Mann] started posting videos on YouTube in 2018 with no film background. Mann previously had a business that sold supplies to grow weed. Today, his company, Burbank-based Dhar Mann Studios, operates on 125,000 square feet of production space, employs roughly 200 people and works with 2,000 actors a year on family friendly programs that touch on how students and families deal with topics such as bullying, narcolepsy, chronic inflammatory bowel disease and hoarding. Mann made $45 million last year, according to Forbes estimates. The majority of his company's revenue comes through YouTube. He tells the Times "I don't think it's just the future of TV — it is TV, and the world is catching on." And then there's this... "My mom would always give me so much crap about it — she would say, 'Why do you want to do YouTube?'" said Chucky Appleby, now an executive at MrBeast. His reply: "Mom, you can make a living from this." MrBeast's holding company, Beast Industries, which employs more than 400 people, made $473 million in revenue last year, according to Business Insider. In the last 28 days, MrBeast content — which includes challenges and stunt videos — received 3.6 billion views on YouTube, Appleby said. Appleby, 28, said he's since bought a Jeep for his mom.
