Google-backed satellites for wildfire detection launch as smoke chokes US, Canada

17 July 2026 at 19:50

As smoke from hundreds of burning wildfires spread across Canada and the United States, the first three operational satellites in the Google-backed FireSat program successfully launched into orbit. The satellites will begin providing wildfire detection capable of spotting even small fires in the United States, Australia, and Europe before the end of the year.

The launch of the microsatellites aboard a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California on July 7, 2026 marks a transition to “initial operational capability” for the FireSat constellation managed by the nonprofit Earth Fire Alliance. After a three-month testing period, the three satellites will begin actively providing data to fire agencies while covering every fire-prone region on Earth at least twice per day.

FireSat represents the first satellite constellation purpose-built for detecting wildfires, including spotting smaller fires that other satellites may miss. The satellites were designed by California-based satellite manufacturer Muon Space and have received over $15 million from Google to support initial deployment. Other notable financial supporters include the Bezos Earth Fund that committed $26 million.

Fear of humanoid robots spurs human workers to strike at Hyundai auto factory

16 July 2026 at 20:09

Thousands of unionized Hyundai auto workers began walking off the job early after negotiations with the South Korean automaker broke down over plans to deploy humanoid robots—the most significant pushback from organized labor so far over the latest wave of robotic automation.

The partial strike at Hyundai’s automotive production complex in the city of Ulsan in South Korea represents “the car industry’s first factory stoppage addressing humanoid robots,” according to The Wall Street Journal. Workers have already ended their day and night shifts two hours early at the world’s largest automotive plant from July 13 through July 15, and plan to start staging four-hour strikes from July 20 to 22 after 15 rounds of negotiations failed to reach an agreement, The Korea Times reported.

Union pushback began as soon as Hyundai Motor Group unveiled the latest version of the Atlas humanoid robot, a two-legged robot that stands at more than 6 feet tall and can lift more than 100 pounds, at the start of this year. Atlas is made by Boston Dynamics, the US robotics company that is about to become a wholly owned subsidiary of Hyundai.

Move over, GPS: Navigation satellites in low-Earth orbit are making a comeback

16 July 2026 at 11:00

New navigation satellites in low-Earth orbit could provide 100 times stronger signal strength compared to GPS and other global navigation satellite systems operating from higher orbital altitudes—enabling greater location accuracy within dense cities, under thick foliage, and even inside buildings. Such signals would also likely prove more resilient to interference at a time when commercial flights, maritime shipping, and even various smartphone apps face increasingly widespread disruption from GPS jamming.

That vision may start to take shape when the first six production satellites of California-based Xona Space Systems are scheduled to launch in October 2026, with early service starting in 2027. Once the full constellation of 258 Pulsar satellites has been launched in the following years, Xona claims that customers will be able to accurately pinpoint their locations anywhere on Earth to within several centimeters.

“That added power means that we can get into that indoor environment that GPS can't get to today,” Adrien Perkins, co-founder and VP of engineering at Xona Space Systems, told Ars. “Our higher power allows you to get into those jamming environments a lot further than you would with GPS by itself.”

US military sent explosive drone boats into combat for the first time

14 July 2026 at 18:00

For the first time in its history, the US military sent explosive-laden drone boats into combat by attacking an Iranian midget submarine and naval port. The unprecedented use of such kamikaze sea drones by the United States comes nearly a decade after Iranian and Houthi forces first demonstrated such weapons.

The US military shared a video showing three “one-way attack surface drones” exploding after approaching an Iranian midget submarine and ship maintenance facility at Iran’s Bandar Abbas Naval Base on the night of July 12. US Central Command, the US military combat command responsible for Middle East operations, described the strikes in a social media post as the “first time American forces have employed sea drones in combat operations.”

The US drone boats were able to “make a low-speed, uncontested approach” to their targets before exploding, according to USNI News, a news service from the nonprofit US Naval Institute. USNI News also identified one of the targets as an Iranian Ghadir-class midget submarine that was out of the water while being suspended from a gantry.

Ukrainian drone strikes forced Russia to stop shipping in vital sea corridor

13 July 2026 at 20:41

Ukrainian drone strikes have forced Russia to completely halt shipping in the Sea of Azov in less than a week, showing once again how a country without traditional naval power can still effectively blockade maritime corridors.

Ukraine’s Unmanned Systems Forces have flown one-way attack drones to target and strike more than 100 Russian tankers and other ships in total, along with posting video evidence showing such drone strikes occurring every night between July 6 and July 14. The campaign has forced Russia to completely shut down the shipping route that flows from Russia’s Don River into the Sea of Azov, and to halt all Kerch Strait shipping transits from the Sea of Azov into the Black Sea, according to Reuters reporting.

The shutdown of such maritime lanes has further isolated the Russian-occupied Crimean Peninsula by cutting off seaborne delivery of fuel in particular. Crimea had already been experiencing severe fuel rationing and power outages as Ukraine stepped up its mid- and long-range drone strike campaign on Russian energy infrastructure and supply lines, leaving behind damaged oil refineries with billowing black smoke and burned-out trucks littering highways.

Increased drone surveillance of illegal July 4th fireworks led to $100K fine

10 July 2026 at 22:37

More cities and towns deployed drones to spot illegal fireworks during the Fourth of July celebrations commemorating America’s 250th anniversary—leading to a $100,000 fine in one instance and coming as part of a broader national trend of first responders turning to drone surveillance.

Police and fire departments have described using both increased drone surveillance and steep fines to deter people from shooting off illegal fireworks, with many departments publicizing their drone videos on social media and warning that their drones will be watching in the future. Incidents involving illegal fireworks have led to costly fires, injuries, and even multiple deaths each year, along with creating local air and noise pollution for residential neighborhoods.

This year, the $100,000 fine for illegal fireworks came from the Sacramento Fire Department in Northern California deploying its own drones for the first time on the Fourth of July, according to CBS News Sacramento. Sacramento Fire Captain Justin Sylvia described the fire department’s drones as being capable of recording scenes in high-resolution video to help investigators identify the house or closest location using Google Maps.

Humanoid robots controlled by surgeons did world-first operation on live pigs

9 July 2026 at 20:12

Humanoid robots have surgically removed the gallbladders from living animals in an unprecedented medical experiment—but not as autonomous machines capable of replacing human doctors. Instead, skilled human surgeons remotely controlled the robots’ movements in a new example of human-robot teamups.

The teleoperated humanoid robots completed two minimally invasive surgeries by removing gallbladders from live pigs during a preclinical trial that was published in the journal Nature. If this approach eventually proves clinically ready for human patients, surgeons could use such humanoid robots to remotely perform robotic-assisted surgical care in smaller hospitals and clinics that lack the resources to install specialized but expensive surgical robots.

“It's a fraction of the cost and it takes a fraction of the space in an operating room,” said Shanglei Liu, an assistant professor of surgery at the University of California San Diego School of Medicine, in an interview with UC San Diego Today. “So it’s easy to deploy, anywhere from rural areas, to the battlefield, and even to space.”

US seeks cheaper hunter-killer drones after Iran destroys $1B worth of Reapers

8 July 2026 at 17:44

The US military has lost dozens of Reaper drones collectively worth more than $1 billion while carrying out surveillance and attack missions over Iran. Now the Pentagon is seeking large numbers of cheaper drones that can perform such missions despite the expectation that many will be lost in combat.

In a call for industry pitches, the Defense Innovation Unit’s notice described the US military’s current reliance on drones and crewed aircraft, each costing more than $30 million, as being “unsustainable against adversaries utilizing layered defenses enabled by increasingly low-cost antiaircraft capabilities.” It envisions deploying more “cost-effective” drones to “overwhelm enemy air defenses even while experiencing numerous [drone] losses.”

That is, in practice, what Ukraine’s military has been demonstrating with its long- and mid-range strike campaign against Russian supply lines, oil refineries, and various energy or industrial targets within Russia or occupied Ukraine. The Ukrainian campaign has been overwhelming Russia’s overstretched air defense capabilities by launching hundreds of relatively inexpensive drones and missiles on a daily basis to attack targets far behind the frontlines, while continuing to damage or destroy Russia’s most sophisticated air defense systems.

How AI could enable autonomous robot workers in workplaces—and maybe homes

7 July 2026 at 11:00

In a world where self-driving robotaxis glide through major city streets without drivers behind the wheel and delivery drones autonomously fly through the skies to drop off orders at customers’ homes, the idea of general-purpose robots helping humans with various tasks in workplaces or even homes may not seem far-fetched.

But that future hinges on developing increasingly autonomous robots powered by modern artificial intelligence—an ambitious vision that has motivated many researchers to become startup founders while also attracting billions of dollars in investment.

“When I started maybe about 15 years ago, I led a project team that was focused on autonomy, but in that era, the goal of that team was to just get a robot to navigate from point A to point B,” said Matt Malchano, vice president of software at the robotics company Boston Dynamics based in Waltham, Massachusetts. “And now, when we think of autonomy, we think of this huge space of tasks and things that we can imagine a robot doing on its own.”

Data centers’ energy demand threatens Trump’s “Made in America” plan

7 July 2026 at 21:03

US manufacturers in many Rust Belt cities and towns are paying significantly higher electricity costs as growing energy demand from data centers strains the largest power grid operator in the United States. The resulting squeeze on profit margins for steelmakers and brick factories could further undermine President Donald Trump’s “Made in America” plan to revive US manufacturing, and it comes as Trump has simultaneously championed the tech companies behind the AI data center boom.

Factory electricity bills are generally rising faster than those for other business customers or residential customers, according to a Reuters analysis. It highlighted the example of the Belden Brick Company, a 141-year-old brick manufacturer in Ohio, whose electricity bills have soared from $1,600 to $12,000 per month due to a higher monthly capacity charge in the 13-state region served by the grid operator PJM Interconnection.

Meanwhile, the Steel Manufacturers Association warned that US steel companies concentrated in the Rust Belt region served by PJM Interconnection are paying tens of millions of dollars in higher power costs per year. Electricity accounts for 20 to 40 percent of the total production costs of making steel.

Kremlin suspected of flying drones over Europe using Russian shadow fleet

6 July 2026 at 20:52

Mysterious drone flights that disrupted major European airports and flew over NATO member military bases hosting US nuclear weapons may be the work of a coordinated Kremlin campaign launched from Russian-linked commercial ships.

That recent assessment from the UK-based International Institute for Strategic Studies used automatic identification system (AIS) maritime tracking data and other publicly available data to show how Russian-linked ships and “shadow fleet” vessels that transport sanctioned Russian oil were often located nearby during various drone incidents. The report suggests that the drone incidents—which impacted a dozen NATO member countries and Ireland between August 2024 and February 2026—also revealed the vulnerability of European air defenses against surveillance and harassment incursions by low-cost drones.

The IISS report identified 144 drone sightings over Europe during that time period that were unlikely to involve hobbyist recreational drones or drone activity related to the war in Ukraine. About 48 percent of the sightings took place over military bases, 26 percent happened over critical infrastructure such as ports and energy or industrial facilities, and 18 percent occurred over civilian airports. Most occurred at night or in the early morning hours before sunrise, and the drones themselves were typically described in media reports as resembling “professional” or “military-style” drones.

FAA proposal: Supersonic airliners can fly over US cities if they’re quiet

2 July 2026 at 17:29

A long-standing ban on commercial supersonic flights over the United States would be overturned in a new rule proposed by the US Federal Aviation Administration. That could pave the way for the possible return of commercial supersonic airliners—as long as such aircraft can reduce the ground-level impacts of their sonic booms.

The FAA originally banned overland supersonic flights by civil aircraft in 1973, following US military tests involving supersonic flights over US cities such as Oklahoma City, Chicago, and St. Louis in the 1960s. But the Trump administration has championed the repeal of the ban to pave the way for supersonic airliners that could operate without disruptive sonic booms. So the FAA’s new rulemaking action on June 30, 2026, follows the direction of an executive order issued by President Trump on June 6, 2025.

The newly proposed rule would replace the 53-year prohibition with an interim “noise-based” certification standard requiring any sonic boom overpressure at the surface to be kept below 0.11 pounds per square foot. That proposed standard is based on the Colorado-based startup Boom Supersonic having demonstrated quiet Mach cutoff flights with its XB-1 aircraft—harnessing specific atmospheric conditions while flying just beyond supersonic speeds at higher altitudes so that the aircraft’s shockwaves are refracted upward into the atmosphere rather than traveling to the ground.

Google’s AI buildout drove 37% increase in electricity use in 2025

2 July 2026 at 11:15

Google reported that its annual electricity consumption rose by 37 percent in 2025—the largest increase in the company’s history as Silicon Valley’s AI data center buildout continues. But the tech giant says it kept operational carbon emissions down by continuing to purchase massive amounts of clean energy.

The company’s latest sustainability report acknowledges that Google’s total electricity usage has increased by more than 250 percent since 2019, which the company attributed to ongoing growth in Google Cloud, YouTube video streaming, and data center construction and operations supporting various AI products and services. The unprecedented 37 percent annual increase is part of an ongoing trend, given how Google’s total electricity consumption also grew by 27 percent in 2024.

“While the path to achieving our climate ambitions will not be linear—given our AI infrastructure buildout is currently accelerating faster than the grid is decarbonizing—we remain focused on scaling abundant and affordable clean power globally and progressing technological innovations that drive down emissions across our operations and the broader industry,” according to the Google sustainability report.

US home battery installations hit record high on rising electricity costs

1 July 2026 at 19:11

US homeowners have embraced home batteries in record-breaking numbers in early 2026, spurred on by state incentives while seeking to offset rising residential electricity costs. The trend could even unlock a more flexible energy supply for power grid operators and even AI data centers.

New home battery installations reached a record 673 megawatts of energy storage in the first quarter of 2026, according to the US Energy Information Administration. That trend was driven by states with high electricity prices that have implemented policies to incentivize home battery installation, Bloomberg News reported.

This residential battery trend stands out as a natural next step for states that have already successfully boosted rooftop solar adoption among homeowners, given how batteries enable homeowners to use stored solar energy at night. California and Hawaii accounted for the majority of new residential battery storage, while Texas and Arizona also saw significantly higher numbers of installations.
