Nightside Aurora Spotted

According to a report by Futurism, the probe was sent by the United Arab Emirates in hopes of studying the Martian landscape. Everything was going as planned, until the unexpected phenomenon shocked the researchers and immediately took still photos to immortalize the event.

The nightside aurora is said to be notoriously hard to detect and let alone take pictures of.

However, as luck would have it, instruments of the scientific vessel were able to catch a glimmer of the aurora that was otherwise proven very difficult to study.

The images were released on Wednesday, June 30, that showed the auroras looking like a shape of bright dots pitted against Mars' dark sky. The discovery only happened by coincidence and was not even part of the science vessel's observation mission.

This discovery sets up the Emirates Mars Mission to possibly encounter more discoveries later this year.

Justin Deighan, a planetary scientist at the University of Colorado as well as the deputy science lead of the mission spoke to Space.com saying, "They're not easy to catch, and so that's why seeing them basically right away with [Emirates Mars Mission] was kind of exciting and unexpected."

He went on and said that the discovery was on their radar but actually being able to witness it for the first time was "a lot of fun."

Auroras on Earth and Mars

Auroras are the creation of the planet's magnetic field as charged particles get sent out into the atmosphere. They alter their own trajectories sporadically, causing the particles to then ionize and create light that we see in a myriad of colors as they mingle with each other.

The auroras on Mars, however, are different to Earth as it doesn't happen in just the north and south poles but appears on every part of the planet.


This happens as the magnetically charged atmosphere of the Red Planet isn't the same as the one located on Earth.


Deighan came to explain it as if taking a bag full of magnets and sprinkling them over the planet, and all of the magnets are pointing in different directions with varying strengths. The scattered magnetic fields then cause the solar wind particles to blast off in different areas that interact with molecules and atoms in the upper atmosphere.
Emirates Mars Mission

The probe used its Ultraviolet Spectrometer to capture the reclusive phenomenon that was originally meant to study the gigantic halo of hydrogen and oxygen surrounding Mars.

The mixture of the two then dissipates towards the outer atmosphere.

Hessa Al Matroushi, the mission's leading figure, said that they didn't anticipate that the instrument could capture such a feat and went on saying that it wasn't designed for it.

However, the accidental mistake is an exciting one for the team as their mission was to capture different sides of the atmosphere of Mars.

The team is excited and hoping for new discoveries that could create newer doors for which they could study in terms of the Martian planet and how solar activity interacts with it regularly.

Proximity to Sun’s Magnetic Field Determines Composition of Rocky Planets, Study Says
Jul 2, 2021 by News Staff / Source



Terrestrial planets (Mercury, Venus, Earth, and Mars) are differentiated into three layers: a metallic core, a silicate shell (mantle and crust), and a volatile envelope of gases, ices, and, for the Earth, liquid water. Each layer has different dominant elements (e.g., increasing iron content with depth and increasing oxygen content to the surface). University of Maryland’s Professor William McDonough and Tohoku University’s Dr. Takashi Yoshizaki have now developed a model showing that the density, mass and iron content of a rocky planet’s core are influenced by its distance from the magnetic field of the Sun.

The new model developed by Professor McDonough and Dr. Yoshizaki shows that during the early formation of our Solar System, when the young Sun was surrounded by a swirling cloud of dust and gas, grains of iron were drawn toward the center by the Sun’s magnetic field.

When the planets began to form from clumps of that dust and gas, planets closer to the Sun incorporated more iron into their cores than those farther away.

The researchers found that the density and proportion of iron in a rocky planet’s core correlates with the strength of the magnetic field around the Sun during planetary formation.

Their study suggests that magnetism should be factored into future attempts to describe the composition of rocky planets, including those outside our Solar System.

The composition of a planet’s core is important for its potential to support life.

On Earth, for instance, a molten iron core creates a magnetosphere that protects the planet from cancer-causing cosmic rays.

The core also contains the majority of the planet’s phosphorus, which is an important nutrient for sustaining carbon-based life.

Using existing models of planetary formation, the scientists determined the speed at which gas and dust was pulled into the center of our Solar System during its formation.

They factored in the magnetic field that would have been generated by the Sun as it burst into being and calculated how that magnetic field would draw iron through the dust and gas cloud.

As the early Solar System began to cool, dust and gas that were not drawn into the Sun began to clump together.

The clumps closer to the Sun would have been exposed to a stronger magnetic field and thus would contain more iron than those farther away from the Sun.

As the clumps coalesced and cooled into spinning planets, gravitational forces drew the iron into their core.



Density of the rocky solar system bodies: uncompressed and solid densities are shown for terrestrial planets and chondrites (gray), respectively; bulk planetary densities are shown for asteroids (blue); for 1 Ceres, its bulk density is a lower limit of its solid density, given its high ice abundance and porosity; the red line shows a fit curve for the planets. Image credit: McDonough & Yoshizaki, doi: 10.1186/s40645-021-00429-4.

When the authors incorporated their model into calculations of planetary formation, it revealed a gradient in metal content and density that corresponds perfectly with what scientists know about the planets in our Solar System.

Mercury has a metallic core that makes up about three-quarters of its mass. The cores of Earth and Venus are only about one-third of their mass, and Mars, the outermost of the rocky planets, has a small core that is only about one-quarter of its mass.

This new understanding of the role magnetism plays in planetary formation creates a kink in the study of exoplanets, because there is currently no method to determine the magnetic properties of a star from Earth-based observations.

“The attributes of our Solar System may be equally applicable to exoplanetary systems,” the researchers said.

“The generation of a planetary magnetosphere, which nurtures life, shapes a planet’s habitability.”

“It is likely that life’s sustainability critically depends on being sited in the Goldilocks zone and having the right amount of metallic core, which contains an appropriate amount of a light element and is not cooling too fast.”

The team’s paper was published in the journal Progress in Earth and Planetary Science.

Were Scientists Wrong About the Planet Mercury? Its Big Iron Core May Be Due to Magnetism!

By UNIVERSITY OF MARYLAND JULY 3, 2021


New research shows the sun’s magnetic field drew iron toward the center of our solar system as the planets formed.

New research from the University of Maryland shows that proximity to the sun’s magnetic field determines a planet’s interior composition.

A new study disputes the prevailing hypothesis on why Mercury has a big core relative to its mantle (the layer between a planet’s core and crust). For decades, scientists argued that hit-and-run collisions with other bodies during the formation of our solar system blew away much of Mercury’s rocky mantle and left the big, dense, metal core inside. But new research reveals that collisions are not to blame—the sun’s magnetism is.

William McDonough, a professor of geology at the University of Maryland, and Takashi Yoshizaki from Tohoku University developed a model showing that the density, mass and iron content of a rocky planet’s core are influenced by its distance from the sun’s magnetic field. The paper describing the model was published on July 2, 2021, in the journal Progress in Earth and Planetary Science.


“The four inner planets of our solar system—Mercury, Venus, Earth, and Mars—are made up of different proportions of metal and rock,” McDonough said. “There is a gradient in which the metal content in the core drops off as the planets get farther from the sun. Our paper explains how this happened by showing that the distribution of raw materials in the early forming solar system was controlled by the sun’s magnetic field.”

McDonough previously developed a model for Earth’s composition that is commonly used by planetary scientists to determine the composition of exoplanets. (His seminal paper on this work has been cited more than 8,000 times.)

McDonough’s new model shows that during the early formation of our solar system, when the young sun was surrounded by a swirling cloud of dust and gas, grains of iron were drawn toward the center by the sun’s magnetic field. When the planets began to form from clumps of that dust and gas, planets closer to the sun incorporated more iron into their cores than those farther away.

The researchers found that the density and proportion of iron in a rocky planet’s core correlates with the strength of the magnetic field around the sun during planetary formation. Their new study suggests that magnetism should be factored into future attempts to describe the composition of rocky planets, including those outside our solar system.

The composition of a planet’s core is important for its potential to support life. On Earth, for instance, a molten iron core creates a magnetosphere that protects the planet from cancer-causing cosmic rays. The core also contains the majority of the planet’s phosphorus, which is an important nutrient for sustaining carbon-based life.

Using existing models of planetary formation, McDonough determined the speed at which gas and dust was pulled into the center of our solar system during its formation. He factored in the magnetic field that would have been generated by the sun as it burst into being and calculated how that magnetic field would draw iron through the dust and gas cloud.

As the early solar system began to cool, dust and gas that were not drawn into the sun began to clump together. The clumps closer to the sun would have been exposed to a stronger magnetic field and thus would contain more iron than those farther away from the sun. As the clumps coalesced and cooled into spinning planets, gravitational forces drew the iron into their core.

When McDonough incorporated this model into calculations of planetary formation, it revealed a gradient in metal content and density that corresponds perfectly with what scientists know about the planets in our solar system. Mercury has a metallic core that makes up about three-quarters of its mass. The cores of Earth and Venus are only about one-third of their mass, and Mars, the outermost of the rocky planets, has a small core that is only about one-quarter of its mass.

This new understanding of the role magnetism plays in planetary formation creates a kink in the study of exoplanets, because there is currently no method to determine the magnetic properties of a star from Earth-based observations. Scientists infer the composition of an exoplanet based on the spectrum of light radiated from its sun. Different elements in a star emit radiation in different wavelengths, so measuring those wavelengths reveals what the star, and presumably the planets around it, are made of.

“You can no longer just say, ‘Oh, the composition of a star looks like this, so the planets around it must look like this,’” McDonough said. “Now you have to say, ‘Each planet could have more or less iron based on the magnetic properties of the star in the early growth of the solar system.’”

The next steps in this work will be for scientists to find another planetary system like ours—one with rocky planets spread over wide distances from their central sun. If the density of the planets drops as they radiate out from the sun the way it does in our solar system, researchers could confirm this new theory and infer that a magnetic field influenced planetary formation.

Mining brines from dormant volcanoes could provide the metals needed for a sustainable future

Valentina Ruiz Leotaud | July 4, 2021 |

Scientists at the University of Oxford are proposing the idea of sustainably extracting copper, gold, zinc, silver and lithium from brines trapped in porous rocks at depths of around 2 kilometres below dormant volcanoes.


In a paper published in the journal Open Science, the researchers explain that the gases released by magma beneath volcanoes are rich in metals. As the pressure drops, the gases separate into steam and brine. Most metals dissolved in the original magmatic gas become concentrated in the dense brine, which in turn gets trapped in porous rock. The less-dense and metal-depleted steam continues up to the surface, where it can form fumaroles, such as those seen at many active volcanoes.

According to the team led by petrologist Jon Blundy, this trapped, subterranean brine is a potential ‘liquid ore’ containing a slew of valuable metals, including gold, lithium and several million tonnes of copper, all of which could be exploited by extracting the fluids to the surface via deep wells.

Employing this method could potentially reduce the cost of mining and ore processing. In addition to this, since geothermal power would be a significant by-product of this green-mining approach, operations would be carbon-neutral.

TRAPPED, SUBTERRANEAN BRINE IS A POTENTIAL ‘LIQUID ORE’ CONTAINING A SLEW OF VALUABLE METALS

“Active volcanoes around the world discharge to the atmosphere prodigious quantities of valuable metals,” Blundy said in a media statement. “Green mining represents a novel way to extract both the metal-bearing fluids and geothermal power, in a way that dramatically reduces the environmental impact of conventional mining.”

To reach this conclusion, the researcher and his team at Oxford joined forces with Russian colleagues and worked on drill cores from a number of deep geothermal systems located in Japan, Italy, Montserrat, Indonesia and Mexico.

Using volcanology, hydrodynamic modelling, geochemistry, geophysics and high-temperature experiments, they were able to confirm their predictions of metal-rich brines.

The scientists say that geophysical surveys of volcanoes show that almost every active and dormant volcano hosts a potentially exploitable ‘lens’ of metal-rich brine. This means that metal exploration may not be limited to relatively few countries such as Chile, the DRC, or the US, as it is currently because volcanoes exist all around the world.
The risks

There are risks to this proposal, though. The main ones are related to the technology that has to be used as the process involves drilling into rock at 2 kilometres depth and at temperatures of more than 450°C. On top of this, the extracted fluids are corrosive, which places limits on the types of drilling materials and they tend to dump their metal load in the well-bore, a problem known as ‘scaling.’

These limitations mean that more research needs to be done around the dynamics of fluid flow and pressure-temperature control in the well-bore and that there will be a need to develop resistive coatings to prevent well-bore corrosion.

Luckily, many of these challenges are already being addressed through deep, hot geothermal drilling projects. In some cases these projects have reached temperatures over 500 °C; and occasionally they have tapped into small pockets of molten rock, for example in Iceland and Hawaii.

The latter challenge, however, is being addressed already as the Oxford team has patented an idea for fluid extraction that guarantees that the fluids continue to flow into the well once drilled, taking into account the permeability and porosity of hot, ductile rock.

Whether there is a risk of triggering volcanic eruptions, the researchers say it is very small, but must be assessed even though they are not planning to drill into magma itself, but into the hot rocks above the magma chamber, which greatly reduces the risk of encountering magma.

The scientists have spent the last five years de-risking the concept, and are now ready to drill an exploratory well at a dormant volcano. This will clarify many of the risks and challenges associated with the technique and will herald a new advance in the understanding of volcanoes and their bounty of energy and metals.

In their view, a working ‘brine mine’ could be 5-15 years away, depending on how well the challenges can be addressed.

 

NASA Continues to Try to Rescue Failing Hubble Space Telescope

TOPICS:Hubble Space TelescopeNASA

By MATT WILLIAMS JULY 4, 2021

Things are not looking very good for the Hubble Space Telescope right now. On Sunday, June 13^th, the telescope’s payload computer suddenly stopped working, prompting the main computer to put the telescope into safe mode. While the telescope itself and its science instruments remain in working order, science operations have been suspended until the operations team can figure out how to get the payload computer back online.

While attempting to restart the computer, the operations team has also tried to trace the issue to specific components in the payload computer and switch to their backup modules. As of June 30th, the team began looking into the Command Unit/Science Data Formatter (CU/SDF) and the Power Control Unit (PCU). Meanwhile, NASA is busy preparing and testing procedures to switch to backup hardware if either of these components are the culprit.

The payload computer is part of the Science Instrument Command and Data Handling (SI C&DH) unit, where it is responsible for controlling and coordinating the scientific instruments aboard the spacecraft. The current issues began when the main computer stopped receiving the “keep-alive” signal from the payload computer – which lets the main computer know that everything is working.

That’s when the operations team began investigating different pieces of hardware on the SI C&DH as the possible source. Based on the available data, the team initially thought that the problem was due to a degrading memory module and tried to switch to one of the module’s multiple backups – but met with failure. On the evening of Thursday, June 17^th, another attempt was made to bring both modules back online, but these attempts also led to failure.

At that point, they began looking into other possibles sources of the shutdown, like the Standard Interface (STINT) hardware. This component is responsible for bridging communications between the computer’s Central Processing Module (CPM), which they began investigating as well. Now, the team is investigating the Command Unit/Science Data Formatter (CU/SDF) and a power regulator within the Power Control Unit (PCU).

Whereas the CU/SDF sends and formats commands and data while the PCU is designed to ensure a steady voltage supply to the payload computer’s hardware. If either of these systems is responsible for the shutdown, then the team must once again go through an operations procedure to switch to the backup units. This time, however, the procedure is more complex and risky than the ones the team executed last time.

Mainly, switching to the backup CU/SDF or backup power regulator requires that several other hardware boxes need to be switched to their backups because of the way they are connected to the SI C&DH unit. The last time the operations team performed this task was back in 2008, which was the last time the CU/SDF module failed. This is what prompted the final servicing mission in 2009, which replaced the entire SI C&DH unit.

Given the complexity of switching multiple systems over to their backups, the operations team is currently reviewing and updating all of Hubble‘s operations procedures, commands, and all other items relating to switching to backup hardware. When they are finished (expected for next week) the team will run a high-fidelity simulator to test their plan of execution and see if they can pull it off.

Since Hubble first launched in 1990, it has taken over 1.5 million images, and more than 600,000 of those were taken since its last servicing mission in 2009. These images are some of the most breathtaking views of the Universe ever taken and have led to substantial discoveries about the nature of our Universe. Here at home, it has deepened our understanding of the Kuiper Belt and Trans-Neptunian Objects (TNOs) like Pluto and Eris.

In 2014, it also observed the farthest object to ever be visited by a spacecraft – the Kuiper Belt Object (KBO) Arrokoth, which the New Horizons mission made a close pass with on Jan. 1^st, 2019. It also observed aurora in the atmospheres of Jupiter, and Saturn, as well as Jupiter’s moon Ganymede. Hubble is also responsible for providing the data that led astronomers to conclude that Ganymede likely contains a large saltwater ocean in its interior.

Beyond the Solar System, Hubble has aided in the first atmospheric studies of exoplanets, helped constrain the size and mass of the Milky Way, the evolution of galaxies over time, revealed the accelerating expansion of the Universe (leading to the theory of Dark Energy), and aided in the study of Dark Matter. These and other accomplishments are all part of Hubble‘s legacy as it celebrates being in space for 31 years, 2 months, and either days.

I think I speak for everyone when I wish Hubble a speedy recovery and hope it has a few more years left in her!

Burned churches stir deep Indigenous ambivalence over faith of forefathers

After hundreds of unmarked graves were found at Canada’s former Catholic-run residential schools, churches in First Nations territories have been destroyed by suspected arson

Leyland Cecco
Sun 4 Jul 2021

For more than a century, the clapboard church set amid rolling hills in western Canada has been a spiritual home to the Upper Similkameen Indian Band.

To build St Anne’s, residents of Chuchuwayha Indian Reserve #2 travelled 40 miles to the closest town, hauling lumber back to their community by horse and wagon.

To reach its pews, generations of congregants would travel miles by foot, past ponderosa pine and sagebrush.

But early last Saturday, thick smoke filled the air and flames ripped through the ageing wooden structure near Hedley in British Columbia. By the time local fire crews arrived, the church had been reduced to a pile of ash.

The community’s fire chief said nothing could be done to save the wooden building. Police say the fire that destroyed the church was suspicious and probably deliberately set. It was the fourth Catholic church on First Nations territory destroyed by fire in less than a month.

“The church meant so much to all of us, especially our ancestors,” Carrie Allison, an elder who helped maintain the church, said in a statement. “When your hurt turns to rage it is not healthy for you or your community.”

As Canada grapples with the discovery of more than 1,000 unmarked graves of Indigenous children at the sites of former residential schools, many have directed their grief and anger at the Catholic church, which ran more than half of the schools across the country.

Disease and hunger were rife at the schools, and survivors have described physical and sexual abuse, often at the hands of priests and Catholic laypeople.

In recent weeks, nearly two dozen churches have been burned or vandalized across the country – eight of which occurred in First Nations territories.

Justin Trudeau joined Indigenous leaders and provincial officials in condemning what are widely suspected to be acts of arson.

“I can’t help but think that burning down churches is actually depriving people who are in need of grieving and healing and mourning from places where they can grieve and reflect and look for support,” the prime minister said on Friday.


Canada must reveal ‘undiscovered truths’ of residential schools to heal

But for many Indigenous people, churches summon contradictory and conflicting emotions: they are the spaces built by their ancestors where generations were baptised and buried, but they also represent the destruction of Indigenous culture and more than a century of fear and physical abuse.

From the 19th century until the 1990s, more than 150,000 Indigenous children were obliged to attend state-funded schools in a campaign to forcibly assimilate them into Canadian society. More than half were run by the Catholic church; thousands of children died of disease, neglect and other causes.

“Those innocent souls were scarified for colonialism,” said Amelia McComber, an Indigenous practitioner and theologian. “And that sacrifice has become the focal point of the hurt and the trauma that has gone on for generations in our communities.”

Entering the schools, children were forbidden to speak their mother tongue, and forced to convert to Christianity. Generations later, many of Indigenous people in Canada still identify as Christian.

“We are a spiritual people and that spirituality was transferred to Christ, because that was the only way our people could pray [in the residential schools]. That was the only way that they could worship,” said McComber.

Some have suggested that First Nations communities should consider cutting all ties with a religion they say was imposed on them.

“It is a legitimate debate for First Nations to talk about removing Catholic churches from our territories, and establishing our own faith as the official religion,” tweeted the writer Robert Jago. “Canada and [First Nations] – these aren’t 100% separate societies – but religion is one of the places they are, or should be.”

But as more churches are burned or vandalized, Indigenous leaders have pleaded for the buildings – many more than a century old – to be spared, despite the anger.

“I can understand it. I don’t like the church. I don’t believe in the church,” chief Clarence Louie of the Osoyoos Indian Band told the National Post, after the church in his community was destroyed. “Many residential school survivors hate the church with a passion – but I have never heard any of them ever suggest people turn to this … I talk to a lot of residential school survivors and, sure, there is a lot of hatred and bitterness and anger – but that still doesn’t mean you go and do arson.”

For Allison, a survivor of the Kamloops Indian residential school, the fire has only worsened the pain.

“I think of all our ancestors that helped to build St Anne’s, looking over us and watching all their hard work and the place they cherished burn to the ground,” she wrote. “A lot of us suffered, but this is not how we do things, and this is not our way. It makes me so sick, sad, and I can only hope I do not know you. I feel sorry for you, and I hope you’re satisfied.”

WHY CANADA IS NOT THE USA

The billionaire and the socialist: No longer the odd couple, believe it or not

BRENT JANG
VANCOUVER
PUBLISHED 1  JULY 3, 2021

B.C. billionaire Jim Pattison, left, and former B.C. premier Glen Clark in 2007.

For Glen Clark, a former B.C. premier, NDP politician and union organizer, redemption came from an unexpected place.

A conflict-of-interest scandal had forced him to resign as premier in 1999, although he kept his seat in the B.C. legislature for another 21 months. In the spring of 2001, he opted not to seek re-election in his riding of Vancouver-Kingsway.

With his political career in tatters and the NDP nearly wiped out by the Liberals in the provincial election in May, 2001, Mr. Clark’s employment prospects appeared limited. At the time, he had criminal charges hanging over him for alleged breach of trust and accepting a benefit. He would later be found not guilty.

Dave Barrett, who served as B.C. premier from 1972 to 1975, phoned Jim Pattison, the billionaire owner of the Vancouver-based Jim Pattison Group, to recommend that he hire Mr. Clark.

Mr. Pattison went with his instincts. Instead of waiting for the outcome of the court case, he took Mr. Clark at his word. “Before I hired him, I asked him a lot of questions and he answered all the questions, and based on what he told me, I believed him,” Mr. Pattison told The Globe and Mail. “I hired him at the time because I thought that he would work out okay with us, and it turned out he did.”


In 2001, exactly 20 years ago as of Saturday, Mr. Clark joined Pattison Group’s sign division as a regional manager. The alliance between the two men has since grown into a flourishing business dynamic. Mr. Clark lacked corporate credentials when he joined the company, but he learned quickly. He became the conglomerate’s president in 2011 and then added the title of chief operating officer in 2017.

Mr. Clark and Mr. Pattison began as a corporate odd couple. Media coverage in the early years pointed out the stark contrasts between the two men. “Yeah, the billionaire and the socialist,” Mr. Clark, now 63 years old, said during an interview.

It would be oversimplifying to portray Mr. Clark solely as the trade unionist and Mr. Pattison as the capitalist. “They’re both kind of self-made out of East Vancouver,” said Bill Tieleman, a communications consultant and former BC NDP strategist who worked for Mr. Clark in 1996 in the premier’s office.

On closer examination, he added, the two men complement each other, and each has a strong work ethic. “There was never a question of them getting along,” Mr. Tieleman said.

This spring, Mr. Clark and Mr. Pattison made a visit together to one of Pattison Group’s newest holdings: a Quality Foods grocery store in Parksville on Vancouver Island.

The trip, for the purpose of taking a close-up look at this new part of Mr. Pattison’s sprawling business empire, underscored the bond between the two men.

The conglomerate’s eclectic assets today include supermarket chains under the Quality Foods and Save-On-Foods banners, car dealerships, billboard advertising, Guinness World Records, Ripley’s Believe It or Not, Great Wolf Lodge, Canadian Fishing Co., and a broadcasting unit with more than 45 radio stations.

Normally, Mr. Pattison and Mr. Clark would have cut a ribbon to open the Quality Foods store and encouraged local fanfare. But with COVID-19 restrictions still in effect, they wanted to avoid drawing a big crowd of shoppers. Instead, they took a corporate jet to Vancouver Island and arranged to be driven to Parksville two days before the grand opening. In late March, the store manager held a scaled-back ceremony with the mayor of Parksville, after Mr. Pattison and Mr. Clark had already left.

Whenever possible behind the scenes, Mr. Pattison and Mr. Clark strive to maintain the tradition of pressing the flesh with managers and employees at the local level. It’s a practice they’ve kept up during the pandemic, despite the necessity of masks and physical distancing.

“You can’t really find out what’s going on, sitting at a desk in Vancouver,” Mr. Clark said. “You can read the statistics and all the financial statements, but you really don’t get a feel for the company until you go talk to people. That may well be old-fashioned, but that’s certainly our core principle.”

On their trips together, Mr. Clark and Mr. Pattison take time to check out not only wholly owned assets but also companies in which Mr. Pattison has significant equity stakes. Among his holdings are 51 per cent of lumber producer Canfor Corp. and 38 per cent of coal-export operator Westshore Terminals Investment Corp.

Pattison Group is a holding company that promotes decentralization, placing responsibility on the leader of each operation to run a tight ship. “We really believe that the heart of the company is the operations,” Mr. Clark said. “We want to talk to the operators, we want to visit the people. We really try hard to visit as many as we can every year. That’s why I’m on the road a lot.”

Mr. Clark has toured more than 200 grocery stores that belong to Pattison Group. “I’ve been to every one of them,” he said. “That’s the most fun part of the job.”

He oversees several of the company’s divisions, including Ripley’s, whose oddity-filled museums have been hurt by pandemic-related shutdowns. Pattison’s grocery chains and car dealerships, meanwhile, have prospered during the pandemic.

Mr. Clark thrived on toiling through long days in his political life. He has learned that, in the corporate world, the pace can be just as gruelling, especially when reporting directly to the boss. Mr. Pattison, who turned 92 last October, still works seven days a week as the owner, chairman and chief executive officer of Pattison Group.

Mr. Pattison’s roots are humble. He was born in Saskatchewan. His parents moved to Vancouver’s working-class east side when he was five years old.

In pursuing his entrepreneurial dreams, Mr. Pattison ended up three courses short of earning a commerce degree from the University of British Columbia. In the summer of 1948, at the age of 19, during a break from studies at UBC, he landed a job that required wearing rubber coveralls while washing used cars with a hose.

At Fred Richmond Motors in Vancouver, he seized an opportunity when the manager allowed him to also sell used cars on the lot, as long as the lone salesman wasn’t on duty. “The first week that I was washing cars, I sold three,” Mr. Pattison said.

He started a single Pontiac and Buick dealership in Vancouver in 1961. Since then, Pattison Group has grown by leaps and bounds. Last year, it had $12.7-billion in revenue, with 51,000 employees across 565 locations worldwide.

Mr. Pattison’s confidence in his staff has been paid back in loyalty. His longest-serving employee is Maureen Chant, who has been his administrative assistant since 1963.

Over the decades, Mr. Pattison has become a notable philanthropist in Canada. In 2017, he donated $75-million to the St. Paul’s Hospital Foundation in Vancouver and $50-million to help build a new children’s hospital in Saskatoon.

“Jimmy Pattison believes in sharing the wealth. He just wants to do it on his own terms,” Mr. Tieleman said. “And he has maintained pretty good relations with organized labour, not that there haven’t been differences in bargaining and issues.”

Mr. Clark was born in Nanaimo on Vancouver Island and raised on Vancouver’s east side. He holds a bachelor of arts degree from Simon Fraser University and graduated with a master’s degree in community and regional planning from UBC.

A former union organizer, he parlayed his backing from the labour movement into winning a seat in the B.C. legislature at the age of 28 in 1986. As B.C. finance minister in the early 1990s, he got to know the buzz in the businesses community.

“He would go to meetings with businesspeople and they would be prepared to be anywhere from skeptical to downright negative,” Mr. Tieleman recalled. “But I can certainly remember meetings where business leaders were just stunned how much he knew about their business. He’s always been a super quick study.”

In the summer of 2002, nearly 14 months after Mr. Clark joined Pattison Group, a B.C. Supreme Court judge cleared him of all criminal charges. He remains a supporter of the BC NDP and has never renounced his social democratic ideals.

He said he admires his boss’s tenacity and is grateful for the opportunity Mr. Pattison gave him to transition into a second career after the rough and tumble of politics. “No one offered me a job, because I obviously had to clear my name. Then Jimmy phoned and invited me down and it was fantastic that he offered me a job,” he recalls. “I had a mortgage to pay and I didn’t have much prospects.”

Despite the mutual admiration, Mr. Pattison cautioned against speculating on succession planning, dismissing the notion that any specific person is in line to take over as CEO. Industry insiders say various scenarios are possible, with several candidates capable of leading Pattison Group when the time comes to pass the torch.

The car salesman turned billionaire emphasized that, as a private company, Pattison Group won’t be telegraphing what exactly happens next. He did say he has no regrets about his decision two decades ago to place his trust in Mr. Clark.

“Well, it’s worked out certainly from our company’s point of view. It’s worked out fine,” Mr. Pattison said. “I just can’t say anything negative about Glen. He’s a hard worker and people like him. If I had to do it over again, I wouldn’t do anything different.”

Hubble telescope spots red, white and blue stars in sparkly cluster

The Hubble Space Telescope has captured a dazzling view of a distant star cluster, one filled with stars that sparkle in red, white and blue, unveiled just in time for the Fourth of July U.S. holiday.

The photo, which NASA and the European Space Agency released July 2, shows the open star cluster NGC 330, a group of stars located about 180,000 light-years away in the Small Magellanic Cloud, a dwarf satellite galaxy to our own Milky Way, in the constellation Tucana, the Toucan.

"Because star clusters form from a single primordial cloud of gas and dust, all the stars they contain are roughly the same age," NASA and ESA officials wrote in an image description. "This makes them useful natural laboratories for astronomers to learn how stars form and evolve."

Astronomers used archived observations from Hubble's Wide Field Camera 3 in 2018 to create this image to support two different studies aimed at understanding how star clusters evolve and how large stars can grow before they explode as supernovas.


"The most stunning object in this image is actually the very small star cluster in the lower left corner of the image, surrounded by a nebula of ionised hydrogen (red) and dust (blue)," ESA officials said in a separate image description. " Named Galfor 1, the cluster was discovered in 2018 in Hubble's archival data, which was used to create this latest image from Hubble."

Scientists studying Galfor 1 will have to wait until NASA's new James Webb Space Telescope (while will launch later this year) can observe it to determine its surrounding nebula has a bow shock feature, ESA added.

The criss-cross patterns of the brilliant stars here are actually an artifact of Hubble itself. They're called diffraction spikes and form when starlight reflects off the four vanes supporting Hubble's secondary mirror, ESA officials said.

While Hubble's view of NGC 330 may add some sparkle to those celebrating the Fourth of July holiday, American astronauts in space have no such luck. They'll be working through the holiday weekend to prepare a visiting SpaceX Dragon cargo ship for its return to Earth on Tuesday (July 6).

The Hubble Space Telescope was launched in 1990 and captured stunning photos of the universe for over 30 years. The iconic observatory is currently offline due to a computer glitch, with NASA working to activate a backup computer in the hopes of restoring Hubble to good health.

Global warming: Arctic’s ‘Last Ice Area’ shows signs of melting much earlier than anticipated

Melting of ice: Even as experts had expected this area - located to the north of Canada and Greenland - to brave the global warming, it is apparently melting as well.

Climate change: The ‘Last Ice Area’, located in the Arctic’s Ice north of Greenland, has started melting earlier than what the scientists had expected, as the scientific community had deemed this area strong enough to be able to withstand the effects of global warming. However, researchers have now published a paper in Communications Earth & Environment journal saying that the area with Last Ice Area or the LIA witnessed record low sea ice concentration in August last year, according to a report in IE. The researchers have also said that likely due to climate change, the sea ice has been thinning for a few years now.

The National Geographic had noted in 2015 that climate projections estimated complete disappearance of Arctic’s summer ice by 2040, but it added that the only place that had the ability to withstand climate change and global warming would be the area of Arctic ice called Last Ice Area.

The report cited the World Wildlife Fund (WWF) as saying that the extent of the Arctic summer ice was shrinking due to climate change, which was an issue not only for the wildlife in the area, but also for the local Inuit population. However, even as experts had expected this area – located to the north of Canada and Greenland – to brave the global warming, it is apparently melting as well.

LIA is a key area that scientists were banking upon to support ice-dependent species when the nearby ice was melting away. Seals use the area for creating dens for their offsprings, while polar bears use it to hunt the seals. The surface of the ice is also used by walruses for foraging.

University of Washington had led the research that has been recently published, and the team said that the observation of the first sign of change in the LIA goes back to 2018, and in August 2020, the vulnerability of the sea ice to the long-term effects of global warming were noticed. They added that just like other parts of the Arctic Ocean, the ice in LIA had been thinning in a gradual manner over the years.

With the help of satellite images, the researchers found that the concentration of sea ice in the area was at a low of 50% as of August 14 last year, of which, they are attributing 80% of thinning to normal factors related to the weather, like winds breaking up the ice and moving it away. The remaining 20%, however, was attributed to longer-term thinning caused by global warming. Lead author of the study Axel Schweiger said that in the winter and spring of 2020, patches of thicker and older ice had drifted into the area, but the thinner, newer ice was sufficiently melted to expose the open ocean, which then led to the beginning of a vicious cycle in which the open ocean absorbed heat energy, as a result melting more ice regardless of the fact that some very thick ice was present in the area.

However, the report said that the study’s results are not applicable to the entire area due to the fact that there are some unknowns.

Two Chinese astronauts stationed in the Tianhe core module of China’s space station Tiangong carried out their first spacewalks on Sunday.

Liu Boming and Tang Hongbo performed the spacewalks with Nie Haisheng, commander of the mission, staying inside the module and assisted in manipulating the station’s robotic arm that helps the other two astronauts with their extravehicular chores.

The spacewalking twosome used new-generation homemade extravehicular mobility unit spacesuits called “Feitian,” meaning flying to space.

Their tasks included installing foot restraints and an extravehicular working platform on the mechanical arm. They also lifted a panoramic camera.

According to China Central Television (CCTV), the extravehicular panoramic camera was initially installed at a lower position on the robotic arm, with a limited vision. A wider perspective of the camera is required for the astronauts to monitor the situation outside the space station, so the astronauts need to install a bracket to lift the camera higher.

More difficult tasks ahead

The spacewalk mission lasted about seven hours outside the cabin.

“There will be another extravehicular task which will be more difficult,” said Liu Xiangyan, deputy chief designer of the space station system. “But I believe that, through the practice and experience of this task, the astronauts will better complete the next task,” said Liu.

The three astronauts were sent into space aboard the Shenzhou-12 spaceship on June 17. They will inhabit the core module until mid-September before returning to Earth.

The villains behind the heat wave

The fossil fuel industry knew all along what climate change would do to people

RYAN COOPER
JULY 4, 2021

Last week, I noted that on June 27, Canada smashed its all-time heat record with a temperature of 116 degrees Fahrenheit, besting the previous record by three whole degrees. It turns out that was just the start: The same small town of Lytton that broke the national record broke it again the next day by hitting 118 degrees, and a third time the following day with a temperature of 121.3 degrees — or more than eight degrees higher than any previous recorded temperature in Canadian history.

"This is the most anomalous regional extreme heat event to occur anywhere on Earth since temperature records began. Nothing can compare," weather historian Christopher Burt told Yale Climate Connections. The heat roasted the forests surrounding Lytton, accelerating wildfires that produced their own "pyroculmulus" storms, creating more lightning and even more blazes. The day after setting the record, fire ripped through Lytton and burned it to the ground just 15 minutes after the first appearance of smoke.

During that same period last week, Greenpeace published a recording of an ExxonMobil lobbyist, Keith McCoy, in which he boasted about working with Sen. Joe Manchin (D-W.Va.) and the Biden administration to weaken Democrats' climate policy, discussed the company's role in funding climate denial, and suggested the company's support of a carbon tax is purely a "talking point" because they expect it will never happen. (The company denied this was true, but there's no reason to take their word for it.)

All Americans are implicated in climate change to some degree. As a country, the U.S. has for decades contributed several times the global average of per capita emissions. But a relative handful of people — principally corporate executives at large fossil fuel companies, their major shareholders, company apparatchiks who hand bribes to politicians, and those that accept those bribes — bear the overwhelming majority of the responsibility. Their amoral greed is directly implicated in the climate disasters that are killing thousands of people already, and will soon be killing millions.

At least several hundred people in western North America were killed by the heat wave — at time of writing, perhaps 320 deaths in Canada and 75 in the United States were being linked to the heat, with likely more remaining to be discovered. Estimates of the costs of melted or broken infrastructure have not yet been compiled, but are sure to be enormous.

It was an awful disaster. Yet in some ways, it was lucky the heat wave struck where it did. Canada and the U.S. are both rich, and not too many people live in that part of either country. If the same scale of heat wave had hit a poor, densely populated country, the death toll would be exponentially greater. Science fiction writer Kim Stanley Robinson's recent book The Ministry of the Future opens with a gripping, terrifying account of a near-future heat wave in India that kills 20 million people in a matter of weeks.

Absent a Second World War-scale global policy mobilization that is nowhere in sight, something like Robinson's scenario is absolutely certain to happen somewhere on the planet, sooner or later. Here's why: Beyond a "wet-bulb" temperature of about 95 degrees (the combined heat and humidity level at which the body can no longer cool itself by sweating), no human being can survive for long and even the healthiest person sitting motionless in the shade will cook themselves to death from the inside within a few hours.

A study from last year found that big chunks of humanity live in places that routinely get quite close to the self-cooking mark, that two particular places (located on the Persian Gulf and in Pakistan) have already seen brief spikes over it, and that the frequency of these extreme heat events is increasing fast almost everywhere. This is also happening much faster than previous climate models predicted, which held that such temperatures would not be reached until the last quarter of this century.

As we are seeing today, though, it does not even take truly extreme heat to kill people. The 2003 heat wave in Europe killed over 70,000 people, and one that hit Russia in 2010 killed about 11,000. Neither got even close to the metabolic limit. Someday, probably within the next decade or two, an ultra-severe heat wave is going to strike a heavily populated region without the resources to cool off its citizens, and millions will die. And heat is just one of dozens of ways — drought, flooding, sea level rise, crop failures, and so on — that climate change will kill people.

ExxonMobil and its fossil-fuel competitors know all this perfectly well. The company knew the basic science of climate change beyond any doubt by 1979 at the latest, from its own research and the work of other scientists. At that point it chose to spend tens of millions of dollars on an enormously successful campaign to sow doubt about what its own data was telling them (following the similarly-murderous strategy of the tobacco industry). The reason, you see, is that doing otherwise would have dented their profits. "Did we join some of these 'shadow groups' to work against some of the early efforts? Yes, that's true. But there's nothing illegal about that," McCoy told the Greenpeace activists. "You know, we were looking out for our investments, we were looking out for our shareholders."

The United States is both the biggest historical contributor to climate change and the only rich country where a major political party outright denies the truth about what is happening. The biggest reason for that is the propaganda campaign executed by ExxonMobil and other deep-pocketed fossil fuel interests, like the Koch family, who successfully convinced conservatives that climate change was fake liberal nonsense.

Well over half of global greenhouse gas emissions have happened since 1990, when the U.S. was the unchallenged global hegemon. If America had done what was obviously in the best interest of itself and all humanity at that point, and led a global movement away from carbon energy, heading off climate change would have been massively cheaper and easier. But that would have been expensive and inconvenient for wealthy fossil fuel executives, so they decided to boil the planet. Millions and millions of deaths are the certain and easily foreseen consequence.
