Moonquakes: Understanding the Moon’s Tectonic Forces Could Protect Future Astronauts

Space agencies and companies looking to set up lunar outposts should build far away from seismic activity.

As humanity looks to the moon for science and economic opportunity in the coming years, understanding potential dangers lurking on the lunar surface could become increasingly important.

Ridges on the moon that signify moonquakes are the subject of a recent research paper, which delves into tectonic activity across the lunar maria, a vast network of dark plains that arose from ancient volcanic activity.

A team of researchers analyzed lunar formations called small mare ridges to create a global moon map, which is the first of its kind. The paper was originally published Dec. 24 in the Planetary Science Journal.

Cole Nypaver, a postdoctoral fellow at the National Air and Space Museum’s Center for Earth and Planetary Studies and one of the paper’s authors, told CNET that the ridges that were identified were formed by faults in the lunar subsurface, which are associated with moonquakes. 

«While those moonquakes are potentially hazardous for long-term lunar exploration missions or permanent outposts, they also present fantastic opportunities to learn more about the interior of the moon and how the moon formed,» Nypaver said.

The moon is shrinking 

Another of the paper’s authors is a scientist named Tom Watters. Back in 2010, Watters discovered that the moon is slowly shrinking because its core is cooling.

The moon’s contraction causes disturbances on its surface. The crust gets compressed and forces material up along faults, which creates ridges, similar to how mountains form on Earth. 

The most common of these ridges are called lobate scarps. They form on the lunar highlands, which are the bright spots we see when we look at the moon. But the small mare ridges only form in the lunar maria, which are the dark areas of the moon that contrast with the highlands.

This research is the first time scientists have documented the ridges throughout the lunar maria. In doing so, we now have a more complete understanding of the moon’s thermal and seismic history, which could give us a better idea of any potential moonquakes in the future. 

«Our results represent the most globally complete understanding of recent lunar tectonism to date,» Nypaver said. «The presence of these additional tectonic features in the lunar maria suggests that the moon may have experienced more global contraction in the recent past than previously thought.»

Moon missions

Humans setting up permanent footholds on the lunar surface have moved from science fiction to real plans for the near future. NASA’s Artemis II mission is set to launch in March at the earliest. And while this mission will only send astronauts to orbit the moon, future Artemis missions plan to land people on the lunar surface and build permanent infrastructure there.

University of Maryland professor Nicholas Schmerr helped NASA develop the Lunar Environment Monitoring Station for Artemis 3, which the crew of the third Artemis mission, currently scheduled for 2028, will deliver to the moon’s surface.

Schmerr said to CNET that this instrument will detect seismic activity in the lunar south polar region. 

«We’ll get a whole new picture of lunar seismic activity both on the South Pole and lunar farside,» Schmerr said. 

LEMS-A3 is a station designed to be self-sustaining, and Schmerr will act as the instrument’s deputy principal investigator for the mission. The LEMS-A3 will assess «tectonics-related seismicity of the region and any hazard the moonquakes (or, for that matter, impacts) could pose to future longer-lived infrastructure,» Schmerr said. 

Setting up shop

NASA isn’t the only one that’s looking to sustain long-term lunar operations. A company called Interlune also wants to set up mining operations on the moon to excavate helium-3, a valuable isotope that could be used for clean energy and quantum computers.

Elon Musk has been talking about building a moon base to launch AI satellites into orbit.

Getting up to speed on the areas of the moon that are more likely to experience moonquakes could influence where space agencies and private companies decide to build outposts in the future.

«There are several upcoming missions to the moon that will carry dedicated seismometers in hopes of detecting a moonquake from a small mare ridge or an asteroid impact on the moon,» Nypaver said. «By identifying a new population of tectonic features in the lunar maria, our work provides additional targets for those missions that seek to use moonquakes to better understand our closest celestial neighbor.»

Google races to put Gemini at the center of Android before Apple’s AI reboot

Google is using its latest Android rollout to position Gemini as the AI layer across phones, Chrome, laptops and cars.

Google is using its latest Android rollout to make Gemini less of a chatbot and more of an operating layer across the phone, browser, car and laptop, just weeks before Apple is expected to show its own Gemini-powered Apple Intelligence reboot at WWDC.
Ahead of its Google I/O developer conference next week, the company previewed a number of Android updates, including AI-powered app automation, a smarter version of Chrome on Android, new tools for creators, a redesigned Android Auto experience, and a sweeping set of new security features.
Alphabet is counting on Gemini to help Google compete directly with OpenAI and Anthropic in the market for artificial intelligence models and services, while also serving as the AI backbone across its expansive portfolio of products, including Android. Meanwhile, Gemini is powering part of Apple’s new AI strategy, giving Google a role in the iPhone maker’s reset even as it races to prove its own version of personal AI on the phone is further along.
Sameer Samat, who oversees Google’s Android ecosystem, told CNBC that Google is rebuilding parts of Android around Gemini Intelligence to help users complete everyday tasks more easily.
“We’re transitioning from an operating system to an intelligence system,” he said.
As part of Tuesday’s announcements. Google said Gemini Intelligence will be able to move across apps, understand what’s on the screen and complete tasks that would normally require a user to jump between multiple services. That means Android is moving beyond the traditional assistant model, where users ask a question and get an answer, and acting more like an agent.
For instance, Google says Gemini can pull relevant information from Gmail, build shopping carts and book reservations. Samat gave the example of asking Gemini to look at the guest list for a barbecue, build a menu, add ingredients to an Instacart list and return for approval before checkout.
A big concern surrounding agentic AI involves software taking action on a user’s behalf without permissions. Samat said Gemini will come back to the user before completing a transaction, adding, “the human is always in the loop.”
Four months after announcing its Gemini deal with Google, Apple is under pressure to show a more capable version of Apple Intelligence, which has been a relative laggard on the market. Apple has long framed privacy, hardware integration and control of the user experience as its advantages.
Google’s Android push is designed to show it can bring AI deeper into the device experience while still giving users control over what Gemini can see, where it can act and when it needs confirmation.
The app automation features will roll out in waves, starting with the latest Samsung Galaxy and Google Pixel phones this summer, before expanding across more Android devices, including watches, cars, glasses and laptops later this year.
The company is also redesigning Android Auto around Gemini, turning the car into another major surface for its assistant. Android Auto is in more than 250 million cars, and Google says the new release includes its biggest maps update in a decade and Gemini-powered help with tasks like ordering dinner while driving.
Alphabet’s AI strategy has been embraced by Wall Street, which has pushed the company’s stock price up more than 140% in the past year, compared to Apple’s roughly 40% gain. Investors now want to see how Gemini can become more central to the products people use every day.

Waymo recalls 3,800 robotaxis after glitch allowed some vehicles to ‘drive into standing water’

Waymo issued a voluntary recall of about 3,800 of its robotaxis to fix software issues that could allow them to drive into flooded roadways.

Waymo is recalling about 3,800 robotaxis in the U.S. to fix software issues that could allow them to “drive onto a flooded roadway,” according to a letter on the National Highway Traffic Safety Administration’s website.
The voluntary recall is for Waymo vehicles that use the company’s fifth and sixth generation automated driving systems (or ADS), the U.S. auto safety regulator said in the letter posted Tuesday.
Waymo autonomous vehicles in Austin, Texas, were seen on camera driving onto a flooded street and stalling, requiring other drivers to navigate around them. It’s the latest example of a safety-related issue for the Alphabet-owned AV unit that’s rapidly bolstering its fleet of vehicles and entering new U.S. markets.
Waymo has drawn criticism for its vehicles failing to yield to school buses in Austin, and for the performance of its vehicles during widespread power outages in San Francisco in December, when robotaxis halted in traffic, causing gridlock.
The company said in a statement on Tuesday that it’s “identified an area of improvement regarding untraversable flooded lanes specific to higher-speed roadways,” and opted to file a “voluntary software recall” with the NHTSA.
“Waymo provides over half a million trips every week in some of the most challenging driving environments across the U.S., and safety is our primary priority,” the company said.
Waymo added that it’s working on “additional software safeguards” and has put “mitigations” in place, limiting where its robotaxis operate during extreme weather, so that they avoid “areas where flash flooding might occur” in periods of intense rain.

Qualcomm tumbles 13% as semiconductor stocks retreat from historic AI-fueled surge

Semiconductor equities reversed sharply after a broad AI-driven advance, with Qualcomm suffering its worst day since 2020 amid inflation concerns and rising oil prices.

Semiconductor stocks fell sharply on Tuesday, reversing course after an extensive rally that had expanded the artificial intelligence investment theme well past Nvidia and driven the industry to unprecedented levels.

Qualcomm plunged 13% and was on track for its steepest single-day decline since 2020. Intel shed 8%, while On Semiconductor and Skyworks Solutions each lost more than 6%. The iShares Semiconductor ETF, which benchmarks the overall sector, fell 5%.

The sell-off came after a key gauge of consumer prices came in above forecasts, and as conflict in Iran pushed crude oil higher—prompting investors to shift away from riskier assets.

The preceding advance had widened the AI opportunity set beyond longtime industry leader Nvidia, which for much of the past several years had largely carried the market to new peaks on its own.

Explosive appetite for central processing units, along with the graphics processing units that power large language models, has sent chipmakers to all-time highs.

Market participants are wagering that the shift from AI model training to autonomous agents will lift demand for additional AI hardware. Among the beneficiaries are memory chip producers, which are raising prices as supply remains tight.

Micron Technology slid 6%, and Sandisk cratered 8%. Sandisk’s stock has surged more than six times over since January.
