Perseverance rover finds organic matter ‘treasure’ on Mars

Just a few of the not too long ago collected samples embody natural matter, indicating that Jezero Crater, which possible as soon as held a lake and the delta that emptied into it, had probably liveable environments 3.5 billion years in the past.

“The rocks that we’ve got been investigating on the delta have the very best focus of natural matter that we’ve got but discovered on the mission,” stated Ken Farley, Perseverance challenge scientist on the California Institute of Know-how in Pasadena.

The rover’s mission, which started on the pink planet 18 months in the past, consists of searching for indicators of historic microbial life. Perseverance is accumulating rock samples that might have preserved these telltale biosignatures. Presently, the rover incorporates 12 rock samples.

Digging into the delta

The positioning of the delta makes Jezero Crater, which spans 28 miles (45 kilometers), of notably excessive curiosity to NASA scientists. The fan-shaped geological function, as soon as current the place a river converged with a lake, preserves layers of Martian historical past in sedimentary rock, which fashioned when particles fused collectively on this previously water-filled surroundings.

The rover investigated the crater ground and located proof of igneous, or volcanic, rock. Throughout its second marketing campaign to check the delta over the previous 5 months, Perseverance has discovered wealthy sedimentary rock layers that add extra to the story of Mars’ historic local weather and surroundings.

“The delta, with its various sedimentary rocks, contrasts superbly with the igneous rocks — fashioned from crystallization of magma — found on the crater ground,” Farley stated.

“This juxtaposition gives us with a wealthy understanding of the geologic historical past after the crater fashioned and a various pattern suite. For instance, we discovered a sandstone that carries grains and rock fragments created removed from Jezero Crater.”

The mission workforce nicknamed one of many rocks that Perseverance sampled as Wildcat Ridge. The rock possible fashioned when mud and sand settled in a saltwater lake because it evaporated billions of years in the past. The rover scraped away on the floor of the rock and analyzed it with an instrument often called the Scanning Liveable Environments with Raman & Luminescence for Organics & Chemical substances, or SHERLOC.

Perseverance can make as much oxygen on Mars as a small tree

This rock-zapping laser features as a flowery black gentle to uncover chemical substances, minerals and natural matter, stated Sunanda Sharma, SHERLOC scientist at NASA’s Jet Propulsion Laboratory in Pasadena.

The instrument’s evaluation revealed that the natural minerals are possible aromatics, or secure molecules of carbon and hydrogen, that are linked to sulfates. Sulfate minerals, usually discovered sandwiched inside the layers of sedimentary rocks, protect details about the watery environments they fashioned in.

Natural molecules are of curiosity on Mars as a result of they characterize the constructing blocks of life, equivalent to carbon, hydrogen and oxygen, in addition to nitrogen, phosphorous and sulfur. Not all natural molecules require life to kind as a result of some will be created via chemical processes.

This mosaic, taken by the rover, shows where Perseverance sampled and abraded the rock NASA scientists call Wildcat Ridge.

“Whereas the detection of this class of organics alone doesn’t imply that life was definitively there, this set of observations does begin to appear like some issues that we have seen right here on Earth,” Sharma stated. “To place it merely, if this can be a treasure hunt for potential indicators of life on one other planet, natural matter is a clue. And we’re getting stronger and stronger clues as we’re transferring via our delta marketing campaign.”

Perseverance in addition to the Curiosity rover has discovered natural matter earlier than on Mars. However this time, the detection occurred in an space the place life might have as soon as existed.

The Wildcat Ridge rock is mudstone that includes organic material. It likely formed in saltwater as  ancient lake water evaporated.

“Within the distant previous, the sand, mud, and salts that now make up the Wildcat Ridge pattern had been deposited beneath circumstances the place life might probably have thrived,” Farley stated.

“The actual fact the natural matter was present in such a sedimentary rock — recognized for preserving fossils of historic life right here on Earth — is essential. Nonetheless, as succesful as our devices aboard Perseverance are, additional conclusions relating to what’s contained within the Wildcat Ridge pattern should wait till it is returned to Earth for in-depth examine as a part of the company’s Mars Pattern Return marketing campaign.”

Returning samples to Earth

The samples collected thus far characterize such a wealth of variety from key areas inside the crater and delta that the Perseverance workforce is excited by depositing a few of the assortment tubes at a delegated web site on Mars in about two months, Farley stated.

As soon as the rover drops off the samples at this cache depot, it is going to proceed exploring the delta.

The rover has been scouting a potential site to drop off its cache of samples.

Future missions can gather these samples and return them to Earth for evaluation utilizing a few of the most delicate and superior devices on the planet. It is unlikely that Perseverance will discover undisputed proof of life on Mars as a result of the burden of proof for establishing it on one other planet is so excessive, Farley stated.

First mission to return samples from another planet set to land on Earth in 2033

“I’ve studied Martian habitability and geology for a lot of my profession and know first-hand the unbelievable scientific worth of returning a rigorously collected set of Mars rocks to Earth,” stated Laurie Leshin, director of NASA’s Jet Propulsion Laboratory, in a press release.

“That we’re weeks from deploying Perseverance’s fascinating samples and mere years from bringing them to Earth so scientists can examine them in beautiful element is actually phenomenal. We are going to be taught a lot.”

Among the various rocks within the delta had been about 65.6 ft (20 meters) aside, they usually every inform completely different tales.

The larger rock and mineral fragments in the Skinner Ridge sample suggest they came from material transported from hundreds of miles outside Jezero Crater.

One piece of sandstone, known as Skinner Ridge, is proof of rocky materials that was possible transported into the crater from lots of of miles away, representing materials that the rover will not have the ability to journey to throughout its mission. Wildcat Ridge, then again, preserves proof of clays and sulfates that layered collectively and fashioned into rock.

As soon as the samples are in labs on Earth, they might reveal insights about probably liveable Martian environments, equivalent to chemistry, temperature and when the fabric was deposited within the lake.

“I feel it is secure to say that these are two of crucial samples that we’ll gather on this mission,” stated David Shuster, Perseverance return pattern scientist on the College of California, Berkeley.

Northvolt dilemma: Can European EVs avoid relying on Asian batteries?

Northvolt dilemma: Can European EVs avoid relying on Asian batteries?

Two months before Northvolt filed for bankruptcy in the US, Robin Zeng, known as China’s “battery king”, had a quick but grim answer as to why European battery makers were struggling to make good products.

“They have a wrong design . . . they have a wrong process . . . and they have the wrong equipment. How can they scale up?” the chief executive of CATL told Nicolai Tangen, the head of Norway’s $1.8tn oil fund. “So almost all mistakes together.”

The bleak assessment from the world’s biggest electric vehicle battery manufacturer captures the scale of the failure for the industries behind the critical technology for Europe’s decarbonisation, leaving governments, companies and investors at a loss as to how to recraft the continent’s strategy to compete with China.

“How are we not taking this more seriously? The European car industry is the heartland of European industry’s supposed prowess,” said one long-standing investor in Northvolt after the collapse into US bankruptcy last week of Europe’s biggest battery hope. “The depth of the crisis for the European car industry is almost unlimited. It’s incredibly grim.”

Brussels took its first steps to establish a battery supply chain across Europe in 2017, with Northvolt at the heart of its ambitions. The bloc has since increased its share of the global battery market from 3 per cent to 17 per cent with annual turnover of €81bn in 2023 after spending more than €6bn of the EU budget to support cross-border battery projects and research and innovation.

But in terms of EV batteries, Asian participants including CATL, BYD, and LG Energy Solution and SK On of South Korea, control about 70 per cent of the global market. Many of the 30 gigafactory projects in Europe have also been designed and built with the help of Chinese and Korean companies.

As the EU’s ambitions have faltered, the struggles of Northvolt have come to embody the challenge the continent faces. The bloc wants to continue encouraging costly investments in the clean technologies needed to meet its ambitious climate goals, while at the same time stemming the wave of plant closures and job cuts that are already spreading across the automotive sector and heavy industries. 

“It’s fair to say we’re at a pivotal moment right now,” said Wouter IJzermans, executive director at the Batteries European Partnership Association. 

People involved in the Northvolt saga said options were narrowing for Europe to address its dependence on China and other parts of Asia for the technology and materials that will be critical as the automotive industry transitions to electric vehicles. 

Efforts are still being made by other start-ups such as France’s Verkor and Volkswagen’s battery business PowerCo, but they are facing either diminished ambitions or tougher financing prospects.

PowerCo is considering building just one out of the two production lines previously planned for its plant in Salzgitter in Germany due to slowing market demand.

Verkor counts Renault as its main client and recently finalised a new €1.3bn financing round to back the construction of a plant in the northern French port city of Dunkirk. But its chief executive Benoit Lemaignan said financing talks were arduous on the back of Northvolt’s woes and the slowdown in the growth of electric vehicle sales this year.

“There was a whole fresh round of audit work and validation of the set-up, our chemistry, the machines and all the equipment,” Lemaignan said. “It’s not something automatic, to find financing today. It’s an issue that goes well beyond Verkor, and affects the financing of all of the energy and climate transition industries.” 

In France, there is also Automotive Cells Company, a venture backed by carmakers Stellantis and Mercedes-Benz, and oil major TotalEnergies, which started producing batteries in 2023. But this year ACC paused plans to expand further with plants in Germany and Italy as it considered switching to a lower-cost form of battery technology and adjusted to a slower EV adoption rate. 

“There are expansion phases and crisis phases, if you draw a parallel with other industries. Perhaps we’re living through the first big challenges for Europe’s battery industry. But there will be factories and there will be clients, we’re seeing that more and more,” Lemaignan said.

Consequences from Northvolt’s US bankruptcy filing are already being felt, with carmakers being forced once again to turn to their Asian suppliers to reduce their exposure to its collapse. 

Germany’s Porsche has never confirmed its relationship with Northvolt, but a person familiar with the agreement between the two companies said the Swedish start-up was contracted to make the batteries for the all-electric Porsche 718, scheduled for launch next year.

As Northvolt’s troubles deepened, the sports-car maker began looking for alternative suppliers. While Porsche also buys batteries from South Korea’s Samsung SDI, LGES and China’s CATL, the person added that diversification was a complicated task at relatively short notice.

Northvolt’s demise means the battle for dominance of the European market is likely to play out between Asian battery makers. 

LGES and SK On both have European plants, in Poland and Hungary respectively, while CATL has a factory in Germany and a second site in Hungary due to begin production next year.

But Tim Bush, a Seoul-based battery analyst at UBS, said there was little prospect at present that the Asian battery makers would be able to help the EU to meet its target for 90 per cent of the continent’s EV batteries to be produced locally by 2030.

Bush noted that Korean battery makers were already paring back their investments in Europe, having invested billions of dollars in plants in North America that have been running at low utilisation rates because of lower than expected consumer demand for EVs.

Potential Chinese battery investments on the continent were also likely to be complicated by the ongoing trade dispute between Brussels and Beijing over EU tariffs on Chinese electric vehicles, he added.

“The Koreans are not expanding, the Chinese have suspended construction and Europe’s new entrants are dropping like flies,” said Bush.

Against such obstacles, the European Commission is weighing plans to require Chinese developers to have plants and bring their intellectual property to Europe in order to access EU subsidies, the FT has previously reported. 

With European start-ups still behind in their ability to manufacture batteries at scale, industry executives say the only solution may be to continue their reliance on Asian participants until homegrown companies can absorb technology knowhow on battery chemistry, mass production and equipment manufacturing.

“We need to find a deal with China because we won’t be able to compete . . . without the support of the Chinese companies that control the mining industry, chemicals, refining and their capacity and competence,” Luca De Meo, Renault’s chief executive, told reporters last month.

But the dilemma is how long Europe needs to wait for the technology transfers to complete, and whether it would already have lost the race by then.

“If you really zoom out, what does Europe want to be? I really question whether Europe wants to give up yet another industry like it did with solar panels. Europe is not a leader in AI. I want my kids to grow up somewhere where there are a lot of jobs,” said a Northvolt executive.

Two members of a Dartmouth College fraternity and a sorority have been charged in the death of a student who was found dead in a river over the summer after attending an off-campus party where alcohol was allegedly served to people who were under 21.

Won Jang, a 20-year-old who was a student at the college and a member of the Beta Alpha Omega fraternity, attended a party off campus in July held by Alpha Phi, a sorority, the Hanover Police Department in New Hampshire said in a statement Friday. The department said Jang and most of the other attendees were under 21 years old and drinking alcohol that was bought and served by Beta Alpha Omega members who were over 21.

After the party, several attendees decided to go for a swim in the Connecticut River, but when a heavy rainstorm occurred many of them left in groups.

“No one in these groups noticed that Jang was unaccounted for. It was confirmed via multiple interviews, to include Jang’s family, that he could not swim,” Hanover police said in a statement.

An autopsy report later determined that Jang’s cause of death was drowning, according to police. His blood alcohol level was .167, the department said. That amount is more than twice the state’s legal amount allowed for drivers 21 and older.

Jang was an undergraduate student from Middletown, Delaware studying biomedical engineering and was a student mentor, according to The Dartmouth. Scott Brown, dean of the college, said Jang “wholeheartedly embraced opportunities at Dartmouth to pursue his academic and personal passions,” according to the paper.

Two members of Beta Alpha Omega fraternity were each charged with a misdemeanor for providing alcohol to persons under 21 years old. The Alpha Phi sorority was also charged with a misdemeanor violation of facilitating an underage alcohol house, the police also said.

Neither Alpha Phi nor Beta Alpha Omega responded to a request for comment.

Dartmouth College said both the Alpha Phi chapter on campus and Beta Alpha Omega were “immediately suspended” after Jang’s death and an internal investigation was launched. The suspensions are still in effect “pending the results of Dartmouth’s internal investigation and conduct process” that the college said is still underway.

“Dartmouth has long valued the contributions that Greek organizations bring to the student experience, when they are operating within their stated values and standards,” the college said in a statement to NPR. “These organizations, as well as all Dartmouth students and community members, have a responsibility to ensure Dartmouth remains a safe, respectful, equitable, and inclusive community for students, faculty, and staff.”

The college also said that because of federal law it “cannot comment on individual disciplinary matters.”

US retailers stretch out Black Friday deals to lure flagging shoppers

Stay informed with free updates

US retailers are extending their one-day seasonal Black Friday discount offers into a sales event lasting weeks in a bid to tempt US consumers to keep spending, as data suggests that their spree which has driven economic growth is beginning to falter.

Walmart, Amazon, Target and Macy’s are among the US retailers already offering deep discounts under the banner of Black Friday, long before it actually arrives this week.

Despite this, general merchandise unit sales were down 3 per cent year-on-year in the week ending 16 November according to data from Circana, which compiles retail point-of-sale data.

The National Retail Federation forecasts that winter holiday sales will reach almost $1tn in the US in November and December, a record $902 a head. But the rate of spending growth is expected to be about 2.5-3.5 per cent, the slowest since 2018.

“We’re seeing this drag-out of incentives to try to widen the window within which [retailers] can draw more consumers,” said Gregory Daco, chief economist at adviser EY Parthenon. “The likely reality in this holiday season is that we see fairly subdued sales because volumes are growing, but at a moderate pace — and [retailers have] much less pricing power.”

Retailers were “incentivising via discounts and different forms of promotions” for those at the lower end of the income spectrum while also “trying to grab higher-income individuals to make purchases during this wider window”, he said.

Although headline inflation has ebbed from the historic highs of the past couple of years, consumers “remain extremely frustrated by the persistence of high prices”, the University of Michigan said this week in a monthly survey.

Consumer spending has been the main driver of America’s robust economic growth in recent months. But consumer confidence is still well below the long-run average, sentiment surveys show.

The prospect of a fresh round of tariffs under Donald Trump’s incoming presidency raises the risk that inflation could take off again, economists have warned — posing a fresh drag on sentiment.

“Donald Trump’s return to the White House with a Republican majority [probably leads] to higher inflation, slower GDP growth and increased budget deficits,” Roland Fumasi, food and agribusiness analyst at Rabobank, said in a note.

If Trump increases tariffs, that would “lead to a rebound in inflation and a slowdown in economic growth”, he said.

“The negative impact on growth could be mitigated by tax cuts and deregulation by a Republican Congress. However, this would increase the budget deficit and reinforce inflation, especially in combination with reduced immigration,” he added.

Black Friday is one of the busiest times of year for consumer goods stores, and the period between Thanksgiving and Cyber Monday — the Monday following the holiday, when electronics vendors discount goods — is critical to retailers’ annual revenue.

NRF chief economist Jack Kleinhenz said that households’ finances were in “good shape”, offering “an impetus for strong spending heading into the holiday season”, although “households will spend more cautiously”.

Brian Cornell, Target chief executive, told analysts this week that consumers were becoming “increasingly resourceful” in the way that they shopped, “focusing on deals and then stocking up when they find them”.

The store group, which disappointed Wall Street this week by forecasting flat sales in the fourth quarter, ran a three-day “Early Black Friday” promotion in early November. On Thursday it launched a promotion titled “Black Friday deals” which will last to the end of the month, including items such as half-price Christmas trees and headphones.

Walmart, the world’s largest retailer, launched the first of two week-long “Black Friday Deals” events on November 11. The second will begin on Monday, offering markdowns on televisions, iPhones, toys and jeans, among other items.

Amazon’s “Black Friday Week” began on Thursday. Home Depot’s “Black Friday Savings” offer lasts from November 7 to December 4.
