Roborock Says a Robot Vacuum With an Arm Will Cost Just a Few Hundred Dollars

Roborock was the first company to market to offer a robot vacuum with a mechanical arm to help you sort items, with the Roborock Saros Z70 making a strong impression on us when we tested it. We liked its capabilities (despite some bugs) and it earned a spot on our list of best robot vacuums, with the caveat that the hefty $2,600 price tag put it out of reach for most people. In a recent interview with CNBC, Quan Gang, president of Roborock, suggested that robot vacuums with arms won’t stay this

Rocket Report: Pivotal Starship test on tap, Firefly wants to be big in Japan

Welcome to Edition 8.07 of the Rocket Report! It's that time again: another test flight of SpaceX's massive Starship vehicle. In this week's report, we have a review of what went wrong on Flight 9 in May and a look at the stakes for the upcoming mission, which are rather high. The flight test is presently scheduled for 6:30 pm local time in Texas (23:30 UTC) on Sunday, and Ars will be on hand to provide in-depth coverage. As always, we welcome reader submissions, and if you don't want to miss a

Anduril, Blue Origin to study how to transport cargo from orbit to Earth for the Pentagon

Blue Origin and Anduril have landed new study contracts with the U.S. Air Force to explore how their technology, including rockets, could move military cargo around the world. The contracts under the Air Force’s Rocket Cargo program are relatively small — Blue Origin’s comes in at $1.37 million and Anduril’s at $1 million. But they could be the first steps in revolutionizing how the Pentagon transports cargo. Study contracts like these are also a strong signal as to which players will later c

Celebrating 50 years of The Rocky Horror Picture Show

When The Rocky Horror Picture Show premiered in 1975, no one could have dreamed that it would become the longest-running theatrical release film in history. But that's what happened. Thanks to a killer soundtrack, campy humor, and a devoted cult following, Rocky Horror is still a mainstay of midnight movie culture. In honor of its 50th anniversary, Disney/20th Century Studios is releasing a newly restored 4K HDR version in October, along with deluxe special editions on DVD and Blu-ray. And the f

SpaceX reveals why the last two Starships failed as another launch draws near

SpaceX is continuing with final preparations for the 10th full-scale test flight of the company's enormous Starship rocket after receiving launch approval Friday from the Federal Aviation Administration. Engineers completed a final test of Starship's propulsion system with a so-called "spin prime" test Wednesday at the launch site in South Texas. Ground crews then rolled the ship back to a nearby hangar for engine inspections, touchups to its heat shield, and a handful of other chores to ready

Rocket Report: Ariane 6 beats Vulcan to third launch; China’s first drone ship

Welcome to Edition 8.06 of the Rocket Report! Two of the world's most storied rocket builders not named SpaceX achieved major successes this week. Arianespace's Ariane 6 rocket launched from French Guiana on its third flight Tuesday night with a European weather satellite. Less than 20 minutes later, United Launch Alliance's third Vulcan rocket lifted off from Florida on a US military mission. These are two of the three big rockets developed in the Western world that have made their orbital debu

The 10 Best Movies Peacock Has to Offer

Peacock deserves its flowers. The platform may not be mentioned as much in the ongoing streaming conversation -- heavy-hitters like Netflix, Disney Plus and Prime Video seem to have things on lock in that sense. That said, the NBC Universal-owned streamer is jam-packed with must-watch movies of all types. And I think this is something more people should be talking about. Universal Pictures has a stellar reputation for releasing box office hits and Oscar-winning movies. It's been doing this for

I did not expect these $100 headphones to outperform my Marshall and JBL like this

OpenRock S2 ZDNET's key takeaways The OpenRock S2 open-style earbuds are available on Amazon for $99. The S2 earbuds are one of the most comfortable open-air earbuds I've ever tested Although the S2 earbuds don't have the punch at the low end, they make up for it in soundstage. $98.99 at Amazon I depend on earbuds to keep my runs from feeling like a chore. This is especially so during the hot summer months, when any distraction from the heat is a necessity. When I go on longer runs, I need ea

After first operational launch, here’s the next big test for ULA’s Vulcan rocket

United Launch Alliance delivered multiple US military satellites into a high-altitude orbit after a prime-time launch Tuesday night, marking an important transition from development to operations for the company's new Vulcan rocket. This mission, officially designated USSF-106 by the US Space Force, was the first flight of ULA's Vulcan rocket to carry national security payloads. Two test flights of the Vulcan rocket last year gave military officials enough confidence to certify it for launching

The Rock Art of Serrania De La Lindosa

The Rock Art of Serrania De La Lindosa Within Southeast Colombia's Orinoco River basin, a series of massive rocky sandstone mesas, called tepuis, rise up from the dense humid jungle. Since ancient times the cliffs of these mountains were important cultural sites. They served as shelters, navigational way points, communal gathering sites, and as giant canvases for their rock art, for early inhabitants to communicate their mythologies, histories, and exploits. One such stretch of these tepuis, La

Space Force officials take secrecy to new heights ahead of key rocket launch

After more than a decade of development and testing, US military officials are finally ready to entrust United Launch Alliance's Vulcan rocket to haul a batch of national security satellites into space. An experimental military navigation satellite, also more than 10 years in the making, will ride ULA's Vulcan rocket into geosynchronous orbit more than 22,000 miles (nearly 36,000 kilometers) over the equator. There are additional payloads buttoned up inside the Vulcan rocket's nose cone, but of

Why does Jeff Bezos keep buying launches from Elon Musk?

Early Monday morning, a Falcon 9 rocket lifted off from its original launch site in Florida. Remarkably, it was SpaceX's 100th launch of the year. Perhaps even more notable was the rocket's payload: two-dozen Project Kuiper satellites, which were dispensed into low-Earth orbit on target. This was SpaceX's second launch of satellites for Amazon, which is developing a constellation to deliver low-latency broadband Internet around the world. SpaceX, then, just launched a direct competitor to its S

How old is the earliest trace of life on Earth?

The question of when life began on Earth is as old as human culture. “It's one of these fundamental human questions: When did life appear on Earth?” said Professor Martin Whitehouse of the Swedish Museum of Natural History. So when some apparently biological carbon was dated to at least 3.95 billion years ago—making it the oldest remains of life on Earth—the claim sparked interest and skepticism in equal measure, as Ars Technica reported in 2017. Whitehouse was among those skeptics. This July

Rocket Lab eyes big defense opportunities with new acquisition

Rocket Lab is signaling to investors, yet again, that it’s more than “just” a rocket company. Rocket Lab’s second-quarter results, which were posted Thursday, show revenues continue to be driven by its space systems business rather than launch. The results also highlighted the company’s acquisition strategy and how its purchase of a new optical payloads company will make it more competitive for lucrative government contracts. The company’s space systems brought in $97.9 million of the $144.5 m

Why I prefer this $180 Fender speaker over competing models by Sony and Bose

Rocket Report: NASA finally working on depots, Air Force tests new ICBM

Welcome to Edition 8.05 of the Rocket Report! One of the most eye-raising things I saw this week was an online update from NASA's Marshall Space Flight Center touting its work on cryogenic propellant management in orbit. Why? Because until recently, this was a forbidden research topic at the space agency, as propellant depots would obviate the need for a large rocket like the Space Launch System. But now that Richard Shelby is retired... As always, we welcome reader submissions, and if you don'

Australia’s first orbital-class rocket stalled seconds after liftoff

Back-to-back engine failures doomed a privately developed Australian rocket moments after liftoff Tuesday, cutting short a long-shot attempt to reach orbit with the country's first homegrown launch vehicle. The 82-foot-tall (25-meter) Eris rocket ignited its four main engines and took off from its launch pad in northeastern Australia at 6:35 pm EDT (22:35 UTC) Tuesday. Liftoff occurred at 8:35 am local time Wednesday at Bowen Orbital Spaceport, the Eris rocket's launch site in the Australian st

Australia’s First Rocket Crashes and Burns Seconds After Liftoff

The first Australian-made orbital rocket to launch from the land down under barely took off for its inaugural test flight, ending roughly 14 seconds after liftoff. Australian startup Gilmour Space launched its Eris rocket for the first time from the company’s Bowen Orbital Spaceport in northern Queensland at 6:35 p.m. ET on Tuesday (8:35 a.m. on Wednesday local time). The first orbital rocket designed and manufactured in Australia had a less-than-ideal first showing. Footage showed Eris struggl

SpaceX Is Gearing Up for Starship’s Next Flight After a String of Explosive Setbacks

SpaceX is prepping the Starship rocket for its upcoming test flight, expected to take place in early August. The rocket’s last few launches did not go smoothly, leaving SpaceX in a bit of a slump as it rushes to develop a fully reusable Starship. The company desperately needs a win ahead of its planned uncrewed Mars launch in 2026, or at least for the rocket not to end up as burnt scraps at the bottom of the ocean. This week, SpaceX transported Starship to its launch site in Starbase, Texas, fo

Firefly Aerospace sets IPO range that would value rocket maker at $5.5 billion

Firefly Aerospace CEO Jason Kim sits for an interview at the Firefly Aerospace mission operations center in Leander, Texas, on July 9, 2025. Firefly Aerospace will price shares at $35 to $39 each in its upcoming initial public offering, a deal that would value the rocket maker at about $5.5 billion. The Texas-based space company said in an updated prospectus Monday that it's planning to sell about 16.2 million shares. The offering could raise up to $631.8 million. Earlier this month, Firefly

Does Rocket Money Work? I’m Convinced After Saving $400 in Subscription Costs

You could be losing money to subscriptions you don't even use. This popular budgeting app can help you cut costs. Getty Images/Rocket Money/Amy Kim/CNET No one likes losing money, yet many of us are allowing dollars to drain from our bank accounts without realizing it. The average US consumer spends around $200 a year on subscriptions they don't even use, according to a recent CNET study. It's easy to see why. You sign up for a free trial or service and forget about it, but the subscription pr

Rocket Lab Has Some Genuine Competition for SpaceX, but It Can’t Reach the Launchpad

California-based startup Rocket Lab is looking to compete with industry leader SpaceX with its upcoming launch vehicle, Neutron. But before it can debut its reusable rocket later this year, the company has to figure out a way to transport Neutron’s components to the southern tip of Wallops Island in Virginia. Rocket Lab is awaiting approval to dredge a permanent channel to the Mid-Atlantic Regional Spaceport (MARS) on Wallops Island, a spaceport surrounded by shallow waters and scarce infrastru

A troubled SPAC plans to buy iRocket for $400M but it already returned most of its cash

An unproven small launch startup is partnering with a severely depleted SPAC trust to do the impossible: go public in a deal they say will be valued at $400 million. Innovative Rocket Technologies Inc. (iRocket) and BPGC Acquisition Corp., a special purpose vehicle company founded by former Commerce Secretary Wilbur Ross, is aiming to close the transaction in the fourth quarter of this year. Interestingly, the SPAC has been depleted of most of its cash after it raised $345 million in its IPO i

Rocket Lab’s first hurdle to flying its new rocket is getting it to the pad

Rocket Lab has asked regulators for permission to transport oversized Neutron rocket structures through shallow waters to a spaceport off the coast of Virginia as it races to meet a September delivery deadline. The request, which was made in July, is a temporary stop gap while the company awaits federal clearance to dredge a permanent channel to the Wallops Island site. Rocket Lab plans to launch its Neutron medium-lift rocket from the Mid-Atlantic Regional Spaceport (MARS) on Wallops Island, V

Elon Now Facing the Possibility That SpaceX Will Never Get Starship Working

SpaceX is nine full-scale test launches into developing its enormous, nearly 400-feet-tall Starship, the most powerful rocket ever built. Over the last two and a half years, we've seen over half a dozen spectacular explosions. Two launches earlier this year sent massive streaks of debris hurtling over the Turks and Caicos Islands, prompting airspace closures. Its most recent test in May ended in an uncontrolled splashdown in the Gulf of Mexico after helplessly spinning on its axis and suffering

This startup wants to use beams of energy to drill geothermal wells

This rock-melting drilling technology from the geothermal startup Quaise is certainly unconventional. The company hopes it’s the key to unlocking geothermal energy and making it feasible anywhere. Geothermal power tends to work best in those parts of the world that have the right geology and heat close to the surface. Iceland and the western US, for example, are hot spots for this always-available renewable energy source because they have all the necessary ingredients. But by digging deep enoug

FAA Allows SpaceX to Drop Starship Rocket Bits on Sacred Hawaiian Island

Elon Musk’s obsession with colonizing Mars is polluting Earth. As SpaceX seeks to ramp up its launches of Starship, it’s also expanding its splashdown area where pieces of the rocket are allowed to litter the Pacific Ocean. A recent expansion threatens marine wildlife surrounding a sacred island in native Hawaiian tradition. The Federal Aviation Administration (FAA) approved SpaceX’s request to rain down debris in the waters surrounding Mokumanamana, an uninhabited island in Northwestern Hawaii

The Qrevo S5V is half the price of Roborock’s best robot vacuums, but it’s still a top-tier cleaner

Roborock Qrevo S5V The Roborock Qrevo S5V is a well-priced robot vacuum and a highly-capable autonomous floor cleaning system. It cleans hard floors and carpets very well, and gets into the corners and underneath furniture with ease. Higher-end models boast greater capacities, but this bot can get the job done in the average home without breaking the bank. I’ve tested the very best robot vacs that Roborock has to offer — from the do-it-all Saros 10R to the all-that-plus-a-robot-arm Saros Z70 —

Scientists Saddened as World's Largest Mars Rock Is Sold at Auction

A rock from Mars that traveled tens if not hundreds of millions of miles before improbably landing on our planet's surface has found its final resting place: the private collection of some secretive plutocrat, whose identity has not been revealed to us members of the nosy public. At roughly 54 pounds, NWA 16788, as it's been dubbed, is by far the largest known rock we have from the Red Planet — the runner up in the category is barely half that weight — and is one of the only 400 meteorites conf
