Asteroids are smacking Earth twice as often as before

Giant rocks from space are falling from the sky more than they used to, but don’t worry.

For the past 290 million years, large asteroids have been crashing into Earth more than twice as often as they did in the previous 700 million years, according to a new study in Thursday’s journal Science.

But no need to cast a wary glance up. Asteroids still only smack Earth on average every million or few million years, even with the increased crash rate. NASA’s list of potential big space rock crashes shows no pending major threats. The biggest known risk is a 4,200-foot (1.3-km) wide asteroid with a 99.988 per cent chance that it will miss Earth when it whizzes very near here in 861 years.

Tell that to the dinosaurs. Most scientists think dinosaurs and a lot of other species went extinct after a huge space rock crashed into Central America about 65 million years ago.

“It’s just a game of probabilities,” said study lead author Sara Mazrouei, a University of Toronto planetary scientist. “These events are still rare and far between that I’m not too worried about it.”

Mazrouei and colleagues in the United Kingdom and United States compiled a list of impact craters on Earth and the moon that were larger than 20 kilometres wide and came up with the dates of them. It takes a space rock that’s 800 metres wide to create holes that big.

The team counted 29 craters that were no older than 290 million years and nine between 291 million years and 650 million years old.

But we can see relatively few big craters on Earth because the planet is more than 70 per cent ocean and past glaciers smoothed out some holes, said University of Toronto planetary scientist Rebecca Ghent, a study co-author.

Extrapolating for what can’t be seen brings the total to about 260 space crashes on Earth in the last 290 million years. Adding in other factors, the science team determined that the current space crash rate is 2.6 times more than the previous 700 million years.

Craters older than 650 million years are mostly wiped off on Earth by glacial forces so the scientists used impact craters on the nearby moon as a stand-in for holes between 650 million and 1 billion years old. The moon is a good guide for estimating Earth crashes, because it is close enough to be in the same bombardment path and its craters last longer.

Asteroid family disaster?

So what happened nearly 300 million years ago?

“Perhaps an asteroid family was broken up in the asteroid belt,” Mazrouei speculated. The space rocks then headed toward the Earth and moon, and the planet got slightly more because it is a bigger target and it has higher gravity, Ghent said.

Outside scientists are split about the research. Jay Melosh at Purdue said he found the number of craters too small to come to a reasonable conclusion, but Harvard’s Avi Loeb said the case was convincing.

Humans might not have emerged without mass extinctions from space rocks about 250 million and 65 million years ago, Loeb said in an email, adding, “but this enhanced impact rate poses a threat for the next mass extinction event, which we should watch for and attempt to avoid with the aid of technology.”

“This demonstrates how arbitrary and fragile human life is,” Loeb wrote.

The ‘Maple Majestic’ wants to be Canada’s homegrown Tesla

Look out Tesla, Canada has a homegrown electric sedan on the way. Well, that’s if AK International Motor Corporation can drum up enough investment to make its EV a reality. Dubbed the “Maple Majestic,” the vehicle is a battery-electric designed to “excel in extreme climate performance without adversely affecting the climate, as befits a vehicle from Canada,” according to its website.

What’s in a name? — The company says the maple leaf is a “symbol of Canada’s warmth and friendliness towards all cultures,” while “majestic” refers to the country’s “status as a Constitutional Monarchy.”

That patriotism carries over into Maple Majestic’s parent company’s lofty goals. AK Motor founder Arkadiusz Kaminski says he wants the company, which he founded in 2012, to become “Canada’s first multi-brand automotive OEM,” and that the “Maple Majestic is intended to be Canada’s flagship brand of automobiles on the world stage.”

Partnerships are key — “We acknowledge that the best chance for the Maple Majestic brand to succeed, lies in continuing to build the relationship with Canada’s parts suppliers and technological innovators, whether they be academic institutions, corporations, or individual inventors,” the company explains. “We are currently seeking partners in automotive engineering, parts manufacturing, automotive assembly, electric propulsion technology, battery technology, autonomous technology, and hybrid power generation technology.”

In other words, don’t expect to be able to buy a Maple Majestic any time soon… and don’t expect to pour over 0-60 mph times, power output, range, or other key stats, because those don’t currently exist. For now, all we have are pictures and a short video clip. But at least those are arresting.

Houston-based energy technology company Quorum Software will merge with a Canadian tech firm to bolster its presence in oil and gas services.

Quorum announced Feb. 15 it plans to merge with Calgary, Alberta-based Aucerna, a global provider of planning, execution and reserves software for the energy sector. The combined firm will operate under the Quorum Software brand.

Gene Austin, CEO of Quorum Software, will continue in his capacity as chief executive of the combined firm. Austin, former CEO of Austin-based marketing tech firm Bazaarvoice Inc., became CEO of Quorum in December 2018.

Aucerna co-founder and CEO Wayne Sim will be appointed to the Quorum Software board of directors. Both companies are backed by San Francisco- and Chicago-based private equity firm Thoma Bravo.

“Over the last 20 years, Quorum has become the leading innovator of software deployed by North American energy companies,” said Austin. “Today, Quorum is expanding the scope of our technology and expertise to all energy-producing regions of the globe. Customers everywhere will have access to a cloud technology ecosystem that connects decision-ready data from operations to the boardroom.”

In addition to the merger announcement, Quorum Software announced it had entered into an agreement with Finnish IT firm TietoEvry to purchase TietoEvry’s entire oil and gas business. The agreement, which includes hydrocarbon management, personnel and material logistics software and related services, is valued at 155 million euros, or $188 million, according to a statement from TietoEvry.

“Our three organizations complement each other — from the software that our great people design to the energy markets where we operate,” said Sim. “Our new company will be able to deliver value to our stakeholders, while accelerating the growth of our combined business and the energy industry’s software transformation.”

The combined company will serve over 1,800 energy companies in 55 countries, according to the announcement. With its headquarters in Houston, Quorum will continue to have a significant presence in Calgary and in Norway, the headquarters for TietoEvry’s oil and gas software business. Quorum will have other offices throughout North America, Latin America, Europe, Asia and the Middle East.

As of Sept. 30, 2020, private equity firm Thoma Bravo had more than $73 billion in assets under management. In late December 2020, Thoma Bravo agreed to acquire Richardson, Texas-based tech firm RealPage in a roughly $10 billion acquisition.

Piece of Kitchener technology lands on Mars on Perseverance rover

KITCHENER — A piece of Kitchener technology has landed on Mars, thanks to NASA’s Perseverance rover.

The rover settled on the planet’s surface on Thursday afternoon. It’s been travelling through space since it was launched from Cape Canaveral, Fla. in July.

“The whole idea of being on a device that we’re sending to another plant with the express mission of looking for traces of past life, it’s pretty mind boggling actually,” said Rafal Pawluczyk, chief technical officer for FiberTech Optica.

The Kitchener-based company made fibre optic cables for the rover’s SuperCam that will examine samples with a camera, laser and spectrometers.

“The cables that we built take the light from that multiplexer and deliver it to each spectrograph,” Pawluczyk said.

The cables connect a device on the rover to the SuperCam, which will be used to examine rock and soil samples, to spectrometers. They’ll relay information from one device to another.

The project started four years ago with a connection to Los Alamos National Lab, where the instruments connected to the cables were developed.

“We could actually demonstrate we can design something that will meet their really hard engineering requirements,” Pawluczyk said.

The Jezero Crater is where the Perseverance rover, with FiberTech Optica’s technology onboard, landed Thursday. Scientists believe it was once flooded with water and is the best bet for finding any evidence of life. FiberTech’s cables will help that in that search.

Ioannis Haranas, an astrophysicist and professor at Wilfrid Laurier University, said the rover isn’t looking for “green men.”

“They’re looking for microbial, single-cell life, any type of fossils and stuff like that,” Haranas said. “That’s why they chose a special landing site. This could be very fertile land for that.”

“It’s very ambitious,” said Ralf Gellert, a physics professor at the University of Guelph.

Gellert helped with previous rover missions and said it’s the first time a Mars rover has landed without a piece of Guelph technology on it. While he’s not part of Perseverance’s mission, he said the possibilities are exciting.

“Every new landing site is a new piece of the puzzle that you can put together with the new results that we have from the other landing sites,” he said.

“It’s scientifically very interesting because, even though we don’t have an instrument on that rover, we can compare what the new rover Perseverance finds at this new landing site,” he said.

Now that Perseverance has landed on Mars, FiberTech is looking ahead to its next possible mission into space.
