CAPE CANAVERAL, Fla. — NASA’s head of human spaceflight says the agency stands behind its astronauts following claims that a U.S. crewmember at the International Space Station sabotaged a Russian Soyuz spacecraft in 2018, causing an air leak at the orbiting laboratory. 

On Friday afternoon (Aug. 13), during a media teleconference about recent delays with Boeing’s Starliner spacecraft, NASA’s human spaceflight chief Kathy Lueders told reporters that the personal attacks against NASA astronaut and Expedition 56 flight engineer Serena Auñón-Chancellor were baseless. 

“Serena is an extremely well-respected crew member who has served her country and made invaluable contributions to the agency,” Lueders told reporters. “And I stand behind Serena — we stand behind Serena and her professional conduct and I did not find this accusation credible.”

Lueders expressed those same sentiments on Twitter Friday afternoon, with NASA’s administrator, Senator Bill Nelson agreeing.: 

“I wholeheartedly agree with Kathy’s statement,” Nelson tweeted. “I fully support Serena and I will always stand behind our astronauts.”

Russian accusations

NASA leadership’s statements on Friday follow on the heels of accusations from an unnamed “high-ranking” official with Russia’s space agency made in the Russian news agency TASS. The agency claims that in 2018, Auñón-Chancellor had an emotional breakdown in space and then damaged a Russian Soyuz spacecraft that was docked at the station so that she could return to Earth early.

The article, published on Thursday (Aug. 12), responds to criticism from U.S. media in regards to the near-disastrous incident involving Russia’s Nauka science module and the International Space Station (ISS) earlier this month.

In the TASS article, Russian journalist Mikhail Kotov interviews an anonymous official at Russia’s space agency, Roscosmos

The article is particularly troublesome because it not only names Auñón-Chancellor — the only female astronaut on station at the time — specifically, but it also reveals a medical condition she suffered on-orbit. (Typically NASA keeps all astronaut medical records and conditions private.) 

Auñón-Chancellor was treated upon her return to Earth for a deep vein thrombosis, also known as a blood clot, in the jugular vein of her neck. But Kotov implies that dealing with such a condition in space could spur her to want to leave the ISS prematurely, and therefore sabotage the spacecraft that brought her to the orbital outpost in an effort to return home ahead of schedule. 

Leaky Soyuz

On Aug. 29, 2018, ISS controllers at NASA’s Johnson Space Center in Houston noticed a slight pressure drop aboard the orbiting outpost. They notified the crew the next day, and the crew was able to trace the leak to a small hole in Russia’s Soyuz MS-09 spacecraft, which had docked to the space station in June with Auñón-Chancellor, European Space Agency astronaut Alexander Gerst and Russian cosmonaut Sergey Prokopyev.

Prokopyev, the commander of the Soyuz at the time, solved the problem by patching the 2-millimeter (0.08 inches) hole using epoxy and gauze. NASA officials stressed that the crew was never in any danger. 

Russian space officials decided to investigate the leak, determined to find out its cause. Shortly thereafter, Dmitry Rogozin — the head of Roscosmos — announced that the breach in the Soyuz wall was a drill hole. And according to Rogozin, the person who made the hole apparently had “a faltering hand,” citing nearby scuff marks that likely resulted when the drill slipped.

Russian officials went one step further insinuating that the unsteady hand was likely due to the culprit drilling in microgravity, meaning one of the crew was to blame — not the Russian engineers involved in the assembly and testing of the Soyuz spacecraft before launch down on Earth.

NASA officials knew the precise locations of the U.S. astronauts before the leak occurred and at the moment it began, thanks to space station surveillance. The video footage indicated that none of the U.S. astronauts on the station were near the Russian segment where the Soyuz vehicle was docked. But the Russians didn’t buy it. They were convinced that one of the crew sabotaged the Soyuz. 

The recent TASS article takes those claims one step further and insists that NASA video of the ISS could have been tampered with and that Russian officials were denied the chance to examine Russian tools and administer polygraphs, or lie detector tests, to the astronauts. 

But the TASS article seems to dismiss the most likely cause of the hole: human error on the ground. The problem most likely happened on Earth, before launch. This was something that Roscosmos was looking into but the agency has never definitively disclosed the results. 

Most likely a technician accidentally damaged the Soyuz spacecraft and then tried to cover up the error with a makeshift patch. That patch could have then become dislodged during flight or its time on-orbit after repeated exposure to extreme temperature differences as the station orbits the Earth.

Looking ahead

Relations between the two space agencies have grown more strained over recent years, but NASA leadership is hopeful for a continued orbital partnership. 

Prior to the launch attempt of Boeing’s Starliner spacecraft on July 30, Nelson told Space.com that he applauded the long-standing relationship between the two agencies. “Terrestrially, we have enormous tensions with Russia, but in space we have cooperation.” 

Nelson also said that he expects Russia will continue to work with NASA to maintain the ISS and that he hopes to announce sometime soon that a cosmonaut will fly on an upcoming SpaceX Crew Dragon flight, something the agency has been trying to arrange for quite some time. 

Perhaps cosmonauts will make their U.S. commercial spaceflight debut with the SpaceX Crew-4 mission, currently slated to launch in2022, Nelson has said, but nothing is confirmed yet.

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.”
