Astronaut Talks Physical/Mental Health, Space And Mars – 91.9 The Bend

Published

Kids at a local middle school will never have to wonder why the sky is blue but space is black because an astronaut explained it to them.

Quispamsis Middle School won a visit from Canadian astronaut David Saint-Jacques through the Junior Astronauts program offered by the Canadian Space Agency.

The Junior Astronauts program designs activities for youth in grades six to nine in science and technology, fitness and nutrition, and communications and teamwork to interest them in a future in science, technology, engineering and math.

Saint-Jacques is an engineer, astrophysicist and family doctor. On December 3, 2018, he flew to the International Space Station and spent 204 days in space, the longest Canadian mission to date.

Saint-Jacques told his audience to take care of themselves, especially when it comes to physical and mental health. He said they might feel young and like they will be healthy forever but they still need to take care of what they eat, much they sleep, and to exercise at least a little bit.

“Your body really is the most important tool you have to accomplish whatever dream you have,” he said.

Saint-Jacques said it’s never too early to practice taking responsibility and becoming a person worthy of confidence.

“As a child, a lot of people make decisions for us and that’s OK but eventually, slowly you need to become responsible for yourself and it’s always good to practice holding your promises to practice taking responsibility for things and becoming someone others can trust I think is really important for whatever you want to do in life,” he said.

Saint-Jacques said it’s important to have fun because you need to have a balance.

“We all want to be someone useful and we all want to be the most beloved person but you have to have fun because you’re no good when you’re sad and the only way to have fun and be successful in your career is to do something you love,” he said.

Saint-Jacques said it was harder to adjust back to Earth than it was to adjust to space. He said he lost his sense of balance, his body forgot to pump blood more to his head than his feet, and like he had the flu or was moving in slow motion which astronauts tend to call “Space Brain.”

One question asked was how he took care of his mental health.

He said when he was having a hard day, he would go to the window and look at Earth to remember why he’s doing it. He said because of the pandemic, it’s like every person is an astronaut in their home dealing with many similar problems on a different scale.

“There’s graffiti on the space station left by a very old astronaut from a very long time ago it says the most important thing is what you’re doing right now,” he said.

Saint-Jacques said one way to do well is to resolve to talk more to avoid explosions but leave others alone if they need space. He suggested getting organized, don’t stay in pyjamas all day, and make a schedule otherwise, you won’t achieve what you want.

“Sometimes we have a dream that seems too big, too crazy, too ambitious, and we’re afraid that we’re not going to make it. The error is to decide not to try in case we fail. That would be a big mistake,” said Saint-Jacques.

“Your dream is not a destination, it’s just a direction. It’s like the North Star. You’ll never get to the North Star ever, but you can still use it as a guide.”

Some of the questions asked were:

  • How long did it take to re-adjust to the gravity on Earth (One week before he could walk without holding someone’s hand, a month before he could ride a bike and two months to feel normal)
  • What was the hardest training he took (Learning to speak Russian in order to learn to fly the Russian rockets, plus the three years away from his family and the balance between work, family and friends)
  • What were some of the first noticeable changes his body experienced in a zero-gravity environment (The feeling of his organs floating up, like jumping off a high diving board, and nausea, congestion and disorientation)

  • How can you tell when you pass through the atmosphere (the rocket stops shaking)
  • What it was like when he first arrived at the space station (The feeling that it had moved from being a machine to a home with his friends)
  • How often were you able to communicate with people on Earth and how often is it with family (Making a call depends on the satellite connection. He called his wife at least every day and every weekend had a video conversation with his family)
  • Was there anything he had to improvise for on the ISS (Some repairs needed to be done because there was no procedure so every day there was improvisation because you can’t plan everything)
  • If space has a sun, why is it so dark (In space even during the day you see the sun while on Earth the sky is blue because sunlight goes through the atmosphere, then diffuses depending on the colours but the blue light doesn’t go straight through although red does. Space is black because it has no reason to be any other colour)
  • Is it possible to one day live on Mars (There’s a lot of issues about living in space so first, we have to get Mars, then we have to deal with the radiation, and then figure out how to land people on Mars ready to work, or to keep them alive since Mars has nothing we need so that will need to require life support systems)

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.”
