Chinese national flag debuts on moon: CNSA – Global Times

The China National Space Administration (CNSA) on Friday showed photos of the first Chinese national flag on the moon. The photo was taken with the flag on board the Chang’e-5 lander vehicle before the ascender blasted off from the moon, marking another proud, inspiring moment in the memories of the Chinese people. 

As soon as the photo was released, it brought cheers from Chinese netizens on twitter-like Sina Weibo. As thousands of netizens left emojis of hearts, clapping hands, and celebrating ribbons on the social platform, some said “if there’s a color for a miracle, it must be the color red on our Chinese national flag.”

The flag, more stylish than before, was made from some special material and weighs only 12 grams. It is the third time that the five-starred red flag on the moon following the mission’s two predecessors, chang’e-3 and -4. Only this time, it comes in the form of actual fabrics other than previous coating on.

The Chinese national flag made its moon debut in December 2013 during the country’s first lunar landing mission of Chang’e-3, and it was recorded in pictures from the spacecraft’s lander and its rover Yutu-1 took for each other.

Chang’e-4 lander and rover Yutu-2 brought China’s national flag to the dark side of the moon, as the Chinese spacecraft made a historic landing in the unvisited region in January 2019.

The flags that Chang’e-3 and -4 carried were in the form of the craft’s coatings, rather than an actual flag. Chinese space technological development has allowed it to take a step forward in the Chang’e-5 mission, the third consecutive safe soft landing on the moon in seven years. 

The Chang’e-5 flag presentation system was developed by China Space Sanjiang Group under the State-owned China Aerospace Science and Industry Corporation, better known as the CASIC.

To ensure a complete and smooth unfolding of the flag, the system adopted a secondary rod-type structure, which is applied in solar panel extending for satellites and other types of spacecraft, CASIC developers told the Global Times on Thursday.

The system weight has been controlled at around one kilogram, and all connecting parts of the system have been given special protection, such as coldness-resistance measures, to help overcome unfavorable lunar surface conditions, including a drastic temperature difference on the moon ranging from 150 C to minus 150 C, Li Yunfeng, the project leader, said in a statement the CASIC company sent to the Global Times.

“An ordinary national flag on Earth would not survive the severe lunar environment,” so the research team also spent more than a year selecting the proper materials to make sure the eventual flag would be strong enough, survive under extreme coldness and heat and capable of showing the fine colors of the national flag and remain so forever, said Cheng Chang, another leading member of the developer team.

The 12-gram national flag represents cutting-edge technology, they said.

How to preserve its original color and shape are the two most crucial questions in designing a national flag that must survive more than 380,000 kilometers away from Earth, under extreme temperatures and radiation during its journey, Wang Ya’nan told the Global Times. 

To get a sense of how difficult the task it is, five of the six flags (except for the one Apollo 11 placed on the moon) brought to the moon in the late 1960s and early 1970s during six US crewed moon landings, have been bleached white due to decades-long solar radiation, although they are reportedly still standing and casting shadows.

Many reports say the Apollo 11 flag was blown over by the exhaust from the ascent engine during lift-off.

The Soviet Union was the first country to imprint its national symbol on the moon, with a football-sized metal ball, carved with its national flag, full of explosives, smashing to the lunar ground in the Luna 2 mission in 1959.

Compared to such a method, China has a more advanced approach, which also greatly increased the complexity of the design, Wang noted.

The Chinese flag that Chang’e-5 displayed officially became the first and only fabric national flag that has ever been placed on the moon in the 21st century, which reminds many of the classic footage of an American national flag planted by Neil Armstrong in the Apollo 11 lunar mission more than five decades ago, observers said.

And they hailed that as the fresh and new icon of human’s lunar exploration, the Chinese national flag would inspire today’s mankind, just as Apollo 11 did, encourage and celebrate generations to make an endeavor to space. 

Displaying a national flag on a celestial body represents the comprehensive strength and technological advancement of the country, Song Zhongping, an aerospace expert and TV commentator, told the Global Times. 

“Yesterday’s memory is still fresh and clear, when the US astronauts stepped outside their cabins and planted the first flag in human history, an American national flag, on the moon in 1969,” Song recalled. “But China is about to showcase our own national flag as well, which I believe is a recognition of the achievements and breakthroughs that we have made, which will be the most valuable thing.”

Some readers have left comments under images and video of the Chang’e-5 landing published on the Global Times twitter account in recent days, saying they would not be convinced and acknowledge China’s achievements until the lander takes an actual photo of the American flag planted by the previous Apollo mission. 

“Is it an original video, or a TikTok post taken in the Gobi desert,” one Twitter user wrote. “Where is the lunar dust while landing,” another asked.

The landing was closely followed by space agencies from all over the world, and the European Space Agency, Russia’s Roscosmos and NASA scientists have extended their congratulations.

Pang Zhihao, a senior space expert based in Beijing, said “the lander vehicle of Chang’e-5 was designed to turn off its engine about two meters above the surface to deliberately avoid blowing dirt.”

And for the sake of innovation, the lander touched down on an unvisited region, which explains why there were no US craft nearby, Pang said.

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.”
