China is planning to build miles-wide ‘megastructures’ in orbit, including solar power plants, tourism complexes, gas stations and even asteroid mining facilities.

The National Natural Science Foundation of China (NSFC) announced a new five-year plan, directing researchers to develop technologies and techniques.

The structures will require lightweight materials to allow larger objects to get into orbit with existing rockets. Researchers will also need to adopt technology to allow for in-orbit assembly and control.

The Chinese government said there is an ‘urgent need’ for megaprojects in space that would require ultra-large spacecraft to keep them in orbit. 

The first project of this type will be a solar power station in high orbit, that will be about a mile wide and ‘beam’ electricity back to a base station in China to feed into the grid by 2035. Increasing to a megawatt of electricity by 2050.

Other projects could include new massive orbital platforms covering miles of space, dwarfing the International Space Station which is just 350ft across.

CHINESE SPACE PROJECTS UNDER DEVELOPMENT 

Space-based solar power

The Chinese government recently opened a research facility to study space-based solar power.

They plan to build a mile wide solar plant and use microwaves to beam signals back down to the Earth. 

They hope to have a megawatt facility in orbit and operational by 2050.

Space-based 32ft aperture telescope

Various departments of the Chinese government are working on a new ‘in-orbit’ telescope project. 

It would have a massive 32ft aperture, which is over twice the size of the NASA James Webb space telescope.

Tiangong space station

China launched the first module of its Tiangong space station earlier this year with plans for future expansion.

It is similar, but significantly smaller than the ISS with new modules added gradually over time.

These megastructures could include space stations like the ISS, which was built up in parts in orbit, with the most recent module added earlier this year.

China already has its own space station travelling above the planet, named Tiangong – first occupied this year.

It plans to gradually expand its size over the coming years, with new research modules and even a telescope.

It is unclear if this will form the basis of a wider base of operations, or if a new facility will be launched in the future.

No specific details have been revealed by the NSFC over the megastructures.

Some, like the space based power plant and giant 32ft aperture telescope, are already in the works, but the new details are about research directions.  

It came in the form of a document published revealing guidelines for researchers on how to access funding.

It directs researchers to focus on making these large-scale projects possible.

Specifically it orders them to focus on developing ‘major strategic aerospace equipment for the future use of space resources’.

It also wants experts to focus on the ‘exploration of the mysteries of the universe, and long-term habitation in orbit’.

The new project isn’t designed to actually put these structures in orbit, but rather spend the next half decade minimising the weight of spacecraft and materials.

It will require multiple rocket launches to build something like a mining facility around an asteroid.

However, finding new, lighter weight but durable materials, could reduce the number of trips and make it more cost effective. 

A 2020 study published by the Chinese Academy of Sciences found that space-based construct was essential to drive space-based technology forward.

‘With the rapid development of space technology and the increasing demand for space missions, the traditional spacecraft manufacturing, deployment and launch methods have been unable to meet existing needs,’ the report found. 

‘In-space assembly (ISA) technologies can effectively adapt to the assembly of large space structures, improve spacecraft performance, and reduce operating costs.’

The Chinese government plans to put a megawatt scale solar power station in orbit and beam the electricity back to Earth for use in the Chinese power grid by 2050

This allows for the creation of ‘fixed structures such as space infrastructure, gas stations, space manufacturing facilities, space tourism complexes, and asteroid mining stations spacecraft,’ the report added.

But to reach this stage, a number of new technologies need to be developed – not just new materials, but advances in robotics and artificial intelligence.

The proposals for research funding include modelling for orbital dynamics, and simulations for controlling a space-based assembly process.

The Chinese government is expected to release about $2.3 million for five research projects exploring large structures in orbit and how to make them feasible.

The Chinese government have directed researchers to create lighter weight materials that would require fewer launches to build structures in Earth orbit in the future

Other work being developed by China includes a huge telescope project that will be built in space from parts shipped up from the ground, in partnership with the University of Surrey in the UK, rather than on the Earth and sent to orbit whole.

Known as the Ultra-Large Aperture On-Orbit Assembly Project, the current focus is on how to automate intelligent on-orbit assembly.

It will have a 10 metre aperture, more than double the size of the NASA and ESA James Webb Space Telescope’s aperture, scheduled to launch later this year.  

The China Academy of Space Technology (CAST) is currently building a test facility in Chongqing, that will eventually receive power beamed down from solar power stations in orbit – with small scale tests starting next year. 

Developed by the Orbital Assembly Corporation (OAC), the Voyager Station could be operational as early as 2027, with the infrastructure built in orbit around the Earth

‘As human exploration of space continues to surpass Earth’s orbit, the in-space manufacturing and assembly of large space structures are essential for human sustainable exploration,’ said Zhihui Xue, a roboticist at the Chinese Academy of Sciences.

It isn’t just China exploring these concepts, a recent report for the UK government suggested the country invest in its own space-based solar plant, and a number of private developers are working on space station concepts.

Among them is one being developed by the Orbital Assembly Corporation (OAC).

The Voyager Station could be operational as early as 2027, with the infrastructure built in orbit around the Earth rather than on the ground and shipped up.

It will feature a series of pods attached to the outside of the rotating ring and some of these pods could be sold to the likes of NASA and ESA for space research. 

China reveals plans to launch a fleet of mile-long solar panels into space to beam energy back to Earth by 2035 – and says the system could have the same output as a nuclear power station by 2050  

China plans to launch a fleet of mile-long solar panels into space by 2035 and beam the energy back to Earth in a bid to meet its 2060 carbon neutral target. 

Reports suggest that once fully operational by 2050, the space-based solar array will send a similar amount of electricity into the grid as a nuclear power station.

The idea for a space power station was first suggested by science-fiction writer Isaac Asimov in 1941 and has been explored by several countries including the UK and US.

Above the Earth there are no clouds and no day or night that could obstruct the sun’s ray – making a space solar station a constant zero carbon power source. 

However, the Chinese government appear to be ready to go from exploring the science and technology behind the idea, to putting a system into practice. 

In the city of Chongqing, the Chinese government has broken ground on the new Bishan space solar energy station where it will begin tests by the end of the year, with the hope of having a functioning megawatt solar energy station by 2030. 

It isn’t clear how much the full space power station will cost to launch or operate, but it is expected to be operational by 2035 and at capacity by 2050.

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.”
