China Aims To Build Its Version Of Elon Musk’s SpaceX Starlink Faster Than Others – China Money Network

Published

 on


China is sending more signals that it will move aggressively toward building its own satellite network in space to realized applications such as Starlink, a satellite internet constellation being constructed by Elon Musk’s SpaceX.

On March 7, Bao Weimin, member of the National Committee of the Chinese People’s Political Consultative Conference and director of the Science and Technology Committee of the Aerospace Science and Technology Group, said in an interview with Chinese media:

“China is planning and developing space Internet satellites and has launched test satellites. We will also establish a national satellite network company to be responsible for coordinating the planning and operation of space satellite Internet network construction.”

In 2020, satellite Internet was included in the scope of China’s New Infrastructure policy initiative, ushering the sector into a stage of explosive growth going forward.

Of course, satellite Internet in space provides many more applications beyond providing Internet access to people in remote areas, like SpaceX’s Starlink.

In its narrow definition, satellite Internet is a high-speed communication network in space, using multiple satellites to form broadband communication network coverage.

This service is more suitable for countries and regions with large areas and sparsely populated areas to solve the communication needs for areas without telecommunication base stations.

In its broad definition, satellite Internet provides satellite network solutions based on communications, navigation, and remote sensing technologies to empower various industries.

Among them, with the satellites as an infrastructure, they are equivalent to mobile towers in space. In the future, they can carry various loads and sensors and form a network to form a distributed computing platform in space.

Combining with 5G, the Industrial Internet, and the Internet of Things, it can spawn a wealth of application scenarios: equipped with 5G payloads, it can meet broadband communications; equipped with cameras, it can achieve remote sensing; with navigation enhancements, it can support autonomous driving.

Assuming that the investment in infrastructure such as satellite development, launch, and ground facilities is about worth around 100 billion yuan in China, the revenue of midstream constellation operators will reach 200 billion yuan, and the market size of ground terminals and industrial applications based on satellite Internet may reach 700 billion yuan, says Xie Tao, founder of Beijing Commsat Technology Development Co., Ltd.

He predicts that 100,000 satellites might be deployed in low earth orbit in the future. Among them, there may be 50,000 to 60,000 satellites from the United States, 30,000 to 40,000 from China, and 10,000 to 20,000 from the United Kingdom, India, Russia and other countries.

Space X alone has launched more than 1,000 satellites in a year and a half. If the scale of 30,000 to 40,000 satellites is to be realized, thousands of satellites need to be deployed every year in the next few years.

However, the current domestic production capacity of micro-satellites is less than 100 per year, so there is at least a 90% gap in supply, says Xie.

These 100,000 satellites were predicted mainly based on them being satellite Internet in its narrow definition, that is, broadband communications in the early stage.

In the later period, it may evolve to the satellite Internet in a broad sense, including the integrated satellite application network of communication, navigation such as construction machinery, oil pipeline monitoring or container monitoring.

In addition, the demand for all-weather, all-time terrestrial resource monitoring and disaster warning has increased significantly, and the market space cannot be underestimated.

Beijing Commsat Technology is positioned as a service provider for the entire industry chain of low-orbit small satellites.

Based on the narrowly defined satellite Internet, it provides one-stop services for basic operators, from constellation design and demonstration, to satellite development and batch production, to satellite terminal research and development and operation model consulting.

The company has served industry customers in environmental protection, land and resources, smart agriculture, transportation and logistics, smart government, scientific research and education.

The company’s satellite factory in Tangshan has completed the main construction of the first phase of the production plant and is expected to enter the trial operation stage of production equipment at the end of June this year.

It is understood that after the completion of this satellite factory, it will realize short-period, low-cost, and flexible mass production of 50-700 kilogram-class satellites.

Beijing Commsat Technology was founded in 2015. In February and December 2018, its successfully launched the “Junior Star One” and 7 “Ladybug Series” satellites respectively, completed the system-level verification of the satellite Internet of Things.

At the beginning of 2021, it received a billion yuan-level strategic investment from the China Internet Investment Fund. This is the seventh round of financing it has completed.

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.”
