With the James Webb Space Telescope (JWST) now powered up and snapping some – some of them huge captures – where does it put them all? On an SSD, of course. It’s a relatively tiny 68GB SSD, according to IEEE Spectrum, which is just enough to handle a day’s worth of JWST images ahead of broadcasting them back to Earth.
Why so humble in size? The JWST is a million miles from Earth, getting bombarded by radiation and temperatures of less than 50 degrees above absolute zero (-370 degrees F). So the SSD, like all other parts, must be radiation hardened. Samsung’s latest pro-level SSD might not cut it. Plus, JWST sends data back to Earth much faster than Hubble – up to 57GB in the four hours it’s in range each day. It seems like just about enough storage.

A court orders the antitrust watchdog to review the original decision.
The UK’s Competition Appeal Tribunal has ordered the country’s antitrust watchdog to review its decision to force Meta to sell Giphy. “We have agreed to reconsider our decision in light of this finding,” a spokesperson for the Competition and Markets Authority (CMA) told the outlet, adding the agency hopes to complete the process within three months. The ruling comes after the tribunal sided with the watchdog on five of the agency’s six claims against the company. However, on the one ruling that went in Meta’s favor, the tribunal said the CMA had failed to properly inform the company of Snapchat’s acquisition of Gfycat, undermining its defense.

Humans are heading back to the moon — and Canada is playing a bigger role than you may realize – CBC News
If all goes as planned, NASA’s most powerful rocket yet will roar to life on the morning of Aug. 29, as part of the Artemis I mission to the moon.
While the mission will be uncrewed — the only passengers on the towering, 32-storey Space Launch System (SLS) and attached Orion capsule are three mannequins — it is the first moonshot for a human-rated spacecraft since Apollo 17 in December 1972.
The goal of the Artemis program is to send humans back to the moon — and ultimately to Mars.
But unlike the Apollo program of the 1960s, Artemis is an international effort. And Canada has no small role in returning humans to deep space; we are building a new Canadarm, a lunar rover and sending astronauts.
Our country’s role is bigger and better than it ever has been in our quiet, but storied, past with space exploration.
Canada was the third country to have a satellite in space. We have sent astronauts to live and work in space. We have provided crucial instruments to Martian rovers, and tools on a spacecraft that charted a distant asteroid. We are partners in the newly launched James Webb Space Telescope, providing the instrument that keeps it guided.
And, of course, we built the iconic robotic arms — Canadarm and Canadarm2 — that have been used on space shuttles and the International Space Station, as commemorated on our $5 bill.
And we, too, are going to the moon.
The mission of Artemis I is to test the SLS rocket and the Orion capsule. But after that comes Artemis II, scheduled for 2024 or 2025, when four astronauts will travel in Orion and orbit the moon.
On that capsule will be a yet-unnamed Canadian astronaut — the first to travel to deep space.
NASA also has plans to build the Lunar Gateway, a small space station that will orbit the moon. Canada is contributing the Canadarm3, built by MDA, to that project — and the new arm is much more sophisticated than the originals.
“Canadarm2 today is on the International Space Station. It’s about 400 kilometres away from Earth, so a few hours’ drive, if you’re going straight up,” said Holly Johnson, vice-president of space and robotic operations at MDA. “Canadarm3 is going to be orbiting the moon at Lunar Gateway, which is 400,000 kilometres from Earth.”
With that extended travel, she said, the CSA is focused on “evolving” the intelligence and the artificial intelligence of the Canadarm.
“It needs to be more autonomous, it needs to be smarter, because communication takes longer to go between Earth and the moon.”
Just as the first two Canadarms were instrumental in building and maintaining the International Space Station, the Canadarm3 will be crucial in building the new Lunar Gateway.
MDA is also partnering with Lockheed Martin and General Motors to provide a robotic arm on a future lunar rover.
And when it comes to lunar rovers, Canadian companies are also working on one capable of spending two weeks in the frigid temperatures of lunar night.
“Canada’s role in space — we’ve been a player from the beginning,” said Ken Podwalski, executive director of space exploration and the Lunar Gateway program manager at the Canadian Space Agency (CSA).
“I just don’t think Canadians … realize how awesome we are. I don’t think they realize the things we’ve done with the shuttle program, with our astronauts, with science, with our satellite programs, our Earth observation, the International Space Station,” he said.
“We’ve been kicking butt for 25 years on that program and we’ve never failed. Never failed. We are absolutely a go-to player in space exploration. And Canadians need to know that.”
Canada may not be as populous as the U.S., Europe or China — some of the major players in space — but we are definitely mighty, said Chris Gainor, an amateur astronomer and space historian.
“On a per capita basis, we don’t spend nearly as much as the Americans,” he said. “But where we’ve been involved in space, we’ve always been kind of right at the front. We’ve been able to succeed when we put our minds to it and put some resources into it.
“I think that’s the important message: It may not be kind of top of mind what we’re doing, but we are actually playing in the big leagues at a bargain-basement price, I would say.”
A $470B industry that’s growing
Canada’s efforts are also about more than simply going to space, according to those in the industry. It’s also about investing in the future and jobs here at home.
“The global space sector was $470 billion in 2021 — and that’s growing. In Canada, it generates revenues of $5 billion, and it creates 20,000 jobs,” said Lisa Campbell, president of the Canadian Space Agency.
“That’s growing as well,” she said. “More and more young people are gravitating toward the space sector, because it’s exciting, it’s interesting. It’s science, technology, math, law, project management, finance — you name it. And there’s going to be huge demand for people in the future to work in the space sector.”
While it may not be immediately apparent that investments in space help us here at home, over the course of 65 years, there have been trickle-down benefits here on Earth, including technology for the cordless vacuum, memory foam and improved eye surgeries.
Canada’s contributions, too, have had knock-on effects: The Canadarm technology was modified and used to support medical robotics, performing thousands of procedures in hospitals on Earth, Johnson noted.
The CSA is also home to an Advisory Council on Deep-Space Healthcare, which aims to learn more about human health in space, with an eye to innovating here at home. And the agency has launched the Deep Space Healthcare Challenge, seeking to create new diagnostic technologies that will serve both deep space missions and those living in remote communities.
“As we figure out how to sustain human health, and feed people further in space, it also helps us with challenges we have here on Earth with remote communities, food security, and detection and prevention and treatment of illnesses,” said Campbell. “Many of the technologies we develop in space help us here on Earth as well.”
The new race to the moon is now on, Podwalski said, and Canada is a big part of it — and should let it be known.
“As Canadians,” he said, “we don’t brag enough.”
NASA's moon rocket moved to launch pad for 1st test flight – CP24
Marcia Dunn, The Associated Press
Published Wednesday, August 17, 2022 3:02PM EDT
CAPE CANAVERAL, Fla. (AP) – NASA’s new moon rocket arrived at the launch pad Wednesday ahead of its debut flight in less than two weeks.
The 322-foot (98-meter) rocket emerged from its mammoth hangar late Tuesday night, drawing crowds of Kennedy Space Center workers, many of whom were not yet born when NASA sent astronauts to the moon a half-century ago. It took nearly 10 hours for the rocket to make the four-mile trip to the pad, pulling up at sunrise.
NASA is aiming for an Aug. 29 liftoff for the lunar test flight. No one will be inside the crew capsule atop the rocket, just three mannequins swarming with sensors to measure radiation and vibration.
The capsule will fly around the moon in a distant orbit for a couple weeks, before heading back for a splashdown in the Pacific. The entire flight should last six weeks.
The flight is the first moonshot in NASA’s Artemis program. The space agency is aiming for a lunar-orbiting flight with astronauts in two years and a lunar landing by a human crew as early as 2025. That’s much later than NASA anticipated when it established the program more than a decade ago, as the space shuttle fleet retired. The years of delays have added billions of dollars to the cost.
“Now for the first time since 1972, we’re going to be launching a rocket that’s designed for deep space,” NASA’s rocket program manager, John Honeycutt, said recently.
NASA’s new SLS moon rocket, short for Space Launch System, is 41 feet (12 meters) shorter than the Saturn V rockets used during Apollo a half-century ago. But it’s more powerful, using a core stage and twin strap-on boosters, similar to the ones used for the space shuttles.
“When you look at the rocket, it almost looks retro. It looks like we’re looking back toward the Saturn V,” NASA Administrator Bill Nelson told reporters earlier this month. “But it’s a totally different, new, highly sophisticated, more sophisticated rocket and spacecraft.”
Twenty-four astronauts flew to the moon during Apollo, with 12 of them landing on it from 1969 through 1972. The space agency wants a more diverse team and more sustained effort under Artemis, named after Apollo’s mythological twin sister.
“I want to underscore that this is a test flight,” Nelson said. “It’s just the beginning.”
This was the rocket’s third trip to the pad. A countdown test in April was marred by fuel leaks and other equipment trouble, forcing NASA to return the rocket to the hangar for repairs. The dress rehearsal was repeated at the pad in June, with improved results.
UNESCO team in Alberta to judge if Wood Buffalo Park should go on endangered list
EDMONTON — A United Nations body that monitors some of the world’s greatest natural glories is in Canada again to assess government responses to ongoing threats to the country’s largest national park, including plans to release treated oilsands tailings into its watershed.
In a series of meetings beginning Thursday, UNESCO investigators are to determine whether Wood Buffalo National Park should be on the list of World Heritage Sites In Danger — a move the agency has already deemed likely.
“Canada is not delivering,” said Melody Lepine of the Mikisew Cree First Nation, which first brought concerns about the northern Alberta park to UNESCO’s attention.
Bigger than Switzerland, Wood Buffalo is one of the world’s largest freshwater deltas and is rich in biodiversity, including nesting sites for endangered whooping cranes. Its maze of wetlands, rivers, lakes and prairie is the largest and most intact ecosystem of its type in North America.
But the park, which straddles Alberta and the Northwest Territories, is slowly drying up through a combination of climate change and upstream developments, such as British Columbia’s Site C dam. As well, research has found increasing evidence of seepage from oilsands tailings ponds into upstream ground and surface water.
In 2017, UNESCO found 15 of 17 ecological benchmarks in the park were deteriorating and gave Canada a list of improvements required for the park to retain its status. This week’s meetings are to assess federal and provincial responses.
A report prepared for Mikisew by scientific consultant Carla Davidson credits the province for establishing buffer areas around the park and Ottawa for water management plans within it. But the document finds little else has been done.
A risk assessment for oilsands tailings ponds hasn’t begun, the report says. Sites in the oilsands region used by whooping cranes haven’t been identified.
Proposals from First Nations to address knowledge gaps have been rejected. No land use plans exist.
The report says provincial groups studying scientific issues have been given restrictive terms of reference.
For example, a group studying mine reclamation can only look at ways to treat and release effluent. Cultural impacts on local First Nations are not considered, nor are cumulative effects of separate developments.
“Alberta has declined so far to implement most of (the recommendations),” the report says. “Instead, we see many examples of Alberta relying on the very policy instruments that have gotten the park to where it is today.”
Meanwhile, both levels of government are preparing regulations to govern the first releases of tailings into the Athabasca River. Those rules are expected in 2025.
Contaminated water can be treated and released safely, says the Mining Association of Canada. In documents posted on its website, the association says tailings ponds can only be reclaimed after the water that fills them is removed.
“Oilsands operators have the demonstrated processes to treat these (contaminants) to levels that are safe for release to the environment,” it says. “After decades of work in this area trying different methods with constant improvement as the goal, industry is confident that water can be treated and safely released to the environment once regulations are established.”
But Gillian Chow-Fraser of the Canadian Parks and Wilderness Society said neither industry nor government have considered other ways of dealing with tailings, such as pumping the water underground.
“(Treating and releasing) isn’t actually a reclamation solution,” she said. “It is a cheap and easy way for these companies to keep producing at the same rate.”
Federal Environment Minister Steven Guilbeault said Ottawa isn’t fixated on releasing treated tailings into the Athabasca.
“This is one of the options but it’s not the only option,” he said Wednesday.
“This idea that some have put out there that the only solution is discharging into the Athabasca River — it’s not the only thing we’re looking at.”
Alberta Environment spokeswoman Carla Jones said effluent is a long way from entering the Athabasca River.
“Treated oilsands mine waters that have been in contact with bitumen will not be released until we can definitively demonstrate, using rigorous science, that it can be done safely and that strict regulatory processes are in place to ensure the protection of human and ecological health,” she wrote in an email.
If UNESCO places Wood Buffalo on its in danger list, it would join 52 other sites from around the world, most of which are imperilled by war or civil unrest. It has only one other site from a G7 country — Florida’s Everglades.
“Having a World Heritage Site is something we’re supposed to be really proud of,” said Chow-Fraser. “This international recognition that things are not as good as they seem here are not something to be proud of.”
Neither industry nor First Nations want permanent tailings ponds on the landscape, Lepine said. But addressing that problem and Wood Buffalo’s overall deterioration can’t be done without more resources and a wider search for solutions.
“They’re not presenting a variety of options,” she said.
Lepine said a move from UNESCO might spur Canadian governments to action.
“This site needs to be listed in danger.”
