A United Arab Emirates spacecraft rocketed away Monday on a seven-month journey to Mars, kicking off the Arab world’s first interplanetary mission.

The liftoff of the Mars orbiter named Amal, or Hope, from Japan marked the start of a rush to fly to Earth’s neighbour that includes attempts by China and the United States.

The UAE said its `Amal’ space probe was functioning after launch as it heads toward Mars.

Omran Sharaf, the project director of Emirates Mars Mission, told journalists in Dubai about an hour and a half after the liftoff that the probe was sending signals. Sharaf said his team now would examine the data, but everything appeared good for now.

People cheered and clapped, with one woman with offering a celebratory cry common for weddings.

The United Arab Emirates launched its first mission to Mars on Monday, part of the country’s efforts to develop its scientific and technological capabilities and reduce its reliance on oil. Reuters

Hope is set to reach Mars in February 2021, the year the UAE celebrates 50 years since the country’s formation.

It blasted off from the Tanegashima Space Center on a small southern Japanese island aboard a Mitsubishi Heavy Industries’ H-IIA rocket, on time at 6:58 a.m. (2158 GMT Sunday) into the blue sky. The launch had been delayed for five days because of stormy weather.

At Mohammed bin Rashid Space Center in Dubai, Emirati men in their traditional white kandora robes and women in their black abayas watched transfixed as the rocket lifted off. As its stages separated, a cheer went out from a group of Emirati men seated on the floor. They began clapping, one using his face mask due to the coronavirus pandemic to wipe away a tear.

“It was great to see everything going according to schedule today. It looks like things are all on track. It’s a huge step in terms of space exploration to have a nation like the UAE taking that giant leap to send a spacecraft to Mars,” Astronomer Fred Watson said.

“Being on route to a planet like Mars is an exceptional achievement.”

A newcomer in space development, the UAE has successfully put three Earth observation satellites into orbit. Two were developed by South Korea and launched by Russia, and a third – its own – was launched by Japan.

A successful Hope mission to Mars would be a major step for the oil-dependent economy seeking a future in space, coming less than a year after the launch of the first UAE astronaut, Hazzaa Ali Almansoori. He spent over a week at the International Space Station last fall.

The UAE has set a goal to build a human colony on Mars by 2117.

“It sends a very strong message to the Arab youth that if the UAE is able to reach Mars in less than 50 years, they could do much more,” Omran Sharaf, the project director of Emirates Mars Mission, told The Associated Press on Sunday as his colleagues prepared for the launch.

The Emiratis involved in the program also acknowledged it represented a step forward for the Arab world, the home of mathematicians and scientists for centuries before the wars and chaos that have gripped wide swathes of it in recent times.

“So the region has been going through tough times in the past decades, if not centuries,” Sharaf said. “Now we have the case of the UAE, a country that’s moving forward with its plans, looking at the future and the future of region also.”

For its first Mars mission, the UAE chose partners instead of doing it all on its own.

“Developing a spacecraft is not easy even if there is ample funding,” said Junya Terazono, an astronomer at Aizu University.

Emirati scientists worked with researchers at the University of Colorado Boulder, University of California, Berkeley and Arizona State University. The spacecraft was assembled at Boulder and transported to Japan as the two countries looked to expand their ties with the rich and politically stable Middle Eastern nation.

The Hope spacecraft, along with its launch, cost $200-million, according to Omran Sharaf, the UAE project manager. Operation costs at Mars have yet to be divulged.

Hope, about the size of a small car, carries three instruments to study the upper atmosphere and monitor climate change while circling the red planet for at least two years. It is set to follow up on NASA’s Maven orbiter sent to Mars in 2014 to study how it went from a warm, wet world that may have harboured microbial life during its first billion years, to the cold, barren place of today.

Hope also plans to send back images of weather changes.

Japan, a U.S. ally, has already long collaborated in defence and space technology.

Resource-poor Japan has traditionally kept friendly ties with Middle Eastern countries. In recent years, Japan has increasingly stepped up trade and defence ties with the UAE, and now seeks to expand its space business.

Two other Mars missions are planned in the coming days by the U.S. and China. The U.S. plans to send a rover named Perseverance to search for signs of ancient life and collect rock and soil samples for return to Earth. Liftoff is targeted for July 30. China aims to explore Mars with an orbiter and rover to study the planet’s surface, and search for water and ice. This launch is set for around July 23.

Japan has its own Mars mission planned in 2024.

Japan Aerospace Exploration Agency, or JAXA, plans to send a spacecraft to the Martian moon Phobos to collect samples to bring back to Earth in 2029.

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.”
