As It Happens6:31NASA moon mission delays are nothing to worry about, says astronaut Chris Hadfield

 

Retired Canadian astronaut Chris Hadfield says that, from where he’s sitting, the Artemis moon missions are coming along just fine.

NASA announced Tuesday it is delaying two upcoming missions — including the flight meant to carry the first Canadian astronaut around the moon — due to technical issues with its spacecraft that could pose a danger to the crew.

Artemis II, the first crewed mission to the moon in half a century, was scheduled to launch this November, but has been pushed to September 2025. Canadian Space Agency astronaut Jeremy Hansen is the flight’s mission specialist.

Artemis III, which aims to send humans to the lunar south pole, will be postponed from 2025 to 2026.

Hadfield, who has flown three space missions and also served as commander of the International Space Station, says these delays are a normal and expected part of space travel. Here is part of his conversation with As It Happens host Nil Köksal.

The safety and technical issues NASA is citing for these delays, what do they signal to you? Is this where a mission like this should be at this stage? 

It’s been 50 years or more since human beings have gone to the moon, so we really want to do it right. You’ve got to be careful. And we flew a test mission a year ago with nobody on board, and learned a lot of things there.

It’s not an airline. It’s not like we’ve got a specific time and date that is absolutely necessary to launch. We will launch as soon as we think everything’s safe enough to have a good chance of success.

The short answer to your question, Nil, is I think things are going along well.

Even when we talk about the significance of some of the things they’ve highlighted? Electronics and the life support system that would keep the astronauts alive?

That’s what spaceships do, right? Every single thing that goes wrong on a spaceship is related to keeping astronauts alive.

I commanded a space station, and things fail all the time. They fail every day. It’s just a big machine. And you try … [to] fix them before you leave Earth if you can, because that improves your chances of success.

That’s the reason you do a test flight is to wring out problems and sort out potential failures, and then work on good solutions to launch with as healthy a ship as possible.

If everything was perfect, I’d be suspicious. You know, I think it’s great that we’re finding problems and working on them and making the vehicle as healthy as possible to get ready to trust it with four people.

If you are Jeremy Hansen and his crewmates, what do you think they’re feeling right now? Relieved or disappointed? Or maybe both, I’d guess?

Neither. It’s just a normal part of the process.

Another six months or a year or whatever it’s going to be, it doesn’t really matter. This is time and preparation and development and mission advancement and making sure we optimize our chances.

For the crew, it’s just, “Yeah, OK. Well, fine.” There was nothing magic about that previous date on the calendar. And there’s nothing magic about this one. And there’s very little chance they’ll launch on this date either. But you have to set a date that everyone’s now working towards.

I don’t think any of my space launches launched on time — or at least, you know, on the first date that we chose. But they all launched, and they were all successful. And it’s because of the process that they’re going through right now.

So if you were to put a date on it … would you even be able to do that at this stage? 

No, nobody can. It’s as simple as that.

The countdown to launch, I know people think it starts at 10, but it starts years in advance…. And at any moment, you can have a launch hold, whether it’s 15 seconds before launch or 15 months before launch.

It’s just a different business, I think, than most people visualize or think about. And this is as hard as it gets, sending four human beings, not 400 kilometres away like I went, but 400,000 kilometres away. So the risks are higher. The opportunities to help them in real time are lower. They can’t just deorbit and come back to Earth.

For Jeremy and his crew, this is life as normal. And they are four great representatives of humanity. I’m super proud to know them.

[In] the previous U.S. administration, there was a sort of sense of urgency infused into getting astronauts back on the moon…. Are you concerned that that kind of urgency from U.S. leaders at that time helped move this along too quickly? 

Politicians come and go, and the electoral cycles are going to continue to happen.

It’s always going to be complex and [involve] a lot of external factors. But you could drive yourself crazy worrying about the things that you have no control over.

I think it’s really good for NASA and the astronauts to be focused hard on the things that they can control and make sure that they’re going to be able to do their part properly.

[There are] those who are not as excited about space exploration as you and many others around the world, who point … to these headlines and say this should all be left to private enterprise rather than a taxpayer-funded agency. What do you say in response to that? 

There’s always a role for government. It’s why we have governments. And there’s a role for private industry, and that’s why we have private industry.

The things that further humanity, that push back the edges of our understanding of things like the CERN particle accelerator or the SNOLAB that’s in Sudbury, or the research laboratories that are right across Canada, or the telescopes that we help build … that’s not the job of private industry, because they can’t make a profit at it.

Exploring the moon, putting human beings on the moon, exploring the rest of the universe, understanding the very nature of dark matter and dark energy — that still takes us collectively to agree that this is something that humanity needs to work on together. And some of our domestic product needs to go towards that, as well as taking care of each other.

So a mission like this one, Artemis, is somewhat in the middle. It’s private companies building the hardware. But it’s still governments fundamentally footing the bill.

And it’s always been that way. That’s what exploration is. It’s always been like that. This is just the current manifestation of it.

Here’s how Helene and other storms dumped a whopping 40 trillion gallons of rain on the South

Published

 on

 

More than 40 trillion gallons of rain drenched the Southeast United States in the last week from Hurricane Helene and a run-of-the-mill rainstorm that sloshed in ahead of it — an unheard of amount of water that has stunned experts.

That’s enough to fill the Dallas Cowboys’ stadium 51,000 times, or Lake Tahoe just once. If it was concentrated just on the state of North Carolina that much water would be 3.5 feet deep (more than 1 meter). It’s enough to fill more than 60 million Olympic-size swimming pools.

“That’s an astronomical amount of precipitation,” said Ed Clark, head of the National Oceanic and Atmospheric Administration’s National Water Center in Tuscaloosa, Alabama. “I have not seen something in my 25 years of working at the weather service that is this geographically large of an extent and the sheer volume of water that fell from the sky.”

The flood damage from the rain is apocalyptic, meteorologists said. More than 100 people are dead, according to officials.

Private meteorologist Ryan Maue, a former NOAA chief scientist, calculated the amount of rain, using precipitation measurements made in 2.5-mile-by-2.5 mile grids as measured by satellites and ground observations. He came up with 40 trillion gallons through Sunday for the eastern United States, with 20 trillion gallons of that hitting just Georgia, Tennessee, the Carolinas and Florida from Hurricane Helene.

Clark did the calculations independently and said the 40 trillion gallon figure (151 trillion liters) is about right and, if anything, conservative. Maue said maybe 1 to 2 trillion more gallons of rain had fallen, much if it in Virginia, since his calculations.

Clark, who spends much of his work on issues of shrinking western water supplies, said to put the amount of rain in perspective, it’s more than twice the combined amount of water stored by two key Colorado River basin reservoirs: Lake Powell and Lake Mead.

Several meteorologists said this was a combination of two, maybe three storm systems. Before Helene struck, rain had fallen heavily for days because a low pressure system had “cut off” from the jet stream — which moves weather systems along west to east — and stalled over the Southeast. That funneled plenty of warm water from the Gulf of Mexico. And a storm that fell just short of named status parked along North Carolina’s Atlantic coast, dumping as much as 20 inches of rain, said North Carolina state climatologist Kathie Dello.

Then add Helene, one of the largest storms in the last couple decades and one that held plenty of rain because it was young and moved fast before it hit the Appalachians, said University of Albany hurricane expert Kristen Corbosiero.

“It was not just a perfect storm, but it was a combination of multiple storms that that led to the enormous amount of rain,” Maue said. “That collected at high elevation, we’re talking 3,000 to 6000 feet. And when you drop trillions of gallons on a mountain, that has to go down.”

The fact that these storms hit the mountains made everything worse, and not just because of runoff. The interaction between the mountains and the storm systems wrings more moisture out of the air, Clark, Maue and Corbosiero said.

North Carolina weather officials said their top measurement total was 31.33 inches in the tiny town of Busick. Mount Mitchell also got more than 2 feet of rainfall.

Before 2017’s Hurricane Harvey, “I said to our colleagues, you know, I never thought in my career that we would measure rainfall in feet,” Clark said. “And after Harvey, Florence, the more isolated events in eastern Kentucky, portions of South Dakota. We’re seeing events year in and year out where we are measuring rainfall in feet.”

Storms are getting wetter as the climate change s, said Corbosiero and Dello. A basic law of physics says the air holds nearly 4% more moisture for every degree Fahrenheit warmer (7% for every degree Celsius) and the world has warmed more than 2 degrees (1.2 degrees Celsius) since pre-industrial times.

Corbosiero said meteorologists are vigorously debating how much of Helene is due to worsening climate change and how much is random.

For Dello, the “fingerprints of climate change” were clear.

“We’ve seen tropical storm impacts in western North Carolina. But these storms are wetter and these storms are warmer. And there would have been a time when a tropical storm would have been heading toward North Carolina and would have caused some rain and some damage, but not apocalyptic destruction. ”

‘Big Sam’: Paleontologists unearth giant skull of Pachyrhinosaurus in Alberta

Published

 on

 

It’s a dinosaur that roamed Alberta’s badlands more than 70 million years ago, sporting a big, bumpy, bony head the size of a baby elephant.

On Wednesday, paleontologists near Grande Prairie pulled its 272-kilogram skull from the ground.

They call it “Big Sam.”

The adult Pachyrhinosaurus is the second plant-eating dinosaur to be unearthed from a dense bonebed belonging to a herd that died together on the edge of a valley that now sits 450 kilometres northwest of Edmonton.

It didn’t die alone.

“We have hundreds of juvenile bones in the bonebed, so we know that there are many babies and some adults among all of the big adults,” Emily Bamforth, a paleontologist with the nearby Philip J. Currie Dinosaur Museum, said in an interview on the way to the dig site.

She described the horned Pachyrhinosaurus as “the smaller, older cousin of the triceratops.”

“This species of dinosaur is endemic to the Grand Prairie area, so it’s found here and nowhere else in the world. They are … kind of about the size of an Indian elephant and a rhino,” she added.

The head alone, she said, is about the size of a baby elephant.

The discovery was a long time coming.

The bonebed was first discovered by a high school teacher out for a walk about 50 years ago. It took the teacher a decade to get anyone from southern Alberta to come to take a look.

“At the time, sort of in the ’70s and ’80s, paleontology in northern Alberta was virtually unknown,” said Bamforth.

When paleontogists eventually got to the site, Bamforth said, they learned “it’s actually one of the densest dinosaur bonebeds in North America.”

“It contains about 100 to 300 bones per square metre,” she said.

Paleontologists have been at the site sporadically ever since, combing through bones belonging to turtles, dinosaurs and lizards. Sixteen years ago, they discovered a large skull of an approximately 30-year-old Pachyrhinosaurus, which is now at the museum.

About a year ago, they found the second adult: Big Sam.

Bamforth said both dinosaurs are believed to have been the elders in the herd.

“Their distinguishing feature is that, instead of having a horn on their nose like a triceratops, they had this big, bony bump called a boss. And they have big, bony bumps over their eyes as well,” she said.

“It makes them look a little strange. It’s the one dinosaur that if you find it, it’s the only possible thing it can be.”

The genders of the two adults are unknown.

Bamforth said the extraction was difficult because Big Sam was intertwined in a cluster of about 300 other bones.

The skull was found upside down, “as if the animal was lying on its back,” but was well preserved, she said.

She said the excavation process involved putting plaster on the skull and wooden planks around if for stability. From there, it was lifted out — very carefully — with a crane, and was to be shipped on a trolley to the museum for study.

“I have extracted skulls in the past. This is probably the biggest one I’ve ever done though,” said Bamforth.

“It’s pretty exciting.”

The ancient jar smashed by a 4-year-old is back on display at an Israeli museum after repair

Published

 on

 

TEL AVIV, Israel (AP) — A rare Bronze-Era jar accidentally smashed by a 4-year-old visiting a museum was back on display Wednesday after restoration experts were able to carefully piece the artifact back together.

Last month, a family from northern Israel was visiting the museum when their youngest son tipped over the jar, which smashed into pieces.

Alex Geller, the boy’s father, said his son — the youngest of three — is exceptionally curious, and that the moment he heard the crash, “please let that not be my child” was the first thought that raced through his head.

The jar has been on display at the Hecht Museum in Haifa for 35 years. It was one of the only containers of its size and from that period still complete when it was discovered.

The Bronze Age jar is one of many artifacts exhibited out in the open, part of the Hecht Museum’s vision of letting visitors explore history without glass barriers, said Inbal Rivlin, the director of the museum, which is associated with Haifa University in northern Israel.

It was likely used to hold wine or oil, and dates back to between 2200 and 1500 B.C.

Rivlin and the museum decided to turn the moment, which captured international attention, into a teaching moment, inviting the Geller family back for a special visit and hands-on activity to illustrate the restoration process.

Rivlin added that the incident provided a welcome distraction from the ongoing war in Gaza. “Well, he’s just a kid. So I think that somehow it touches the heart of the people in Israel and around the world,“ said Rivlin.

Roee Shafir, a restoration expert at the museum, said the repairs would be fairly simple, as the pieces were from a single, complete jar. Archaeologists often face the more daunting task of sifting through piles of shards from multiple objects and trying to piece them together.

Experts used 3D technology, hi-resolution videos, and special glue to painstakingly reconstruct the large jar.

Less than two weeks after it broke, the jar went back on display at the museum. The gluing process left small hairline cracks, and a few pieces are missing, but the jar’s impressive size remains.

The only noticeable difference in the exhibit was a new sign reading “please don’t touch.”
