SpaceX Crew Dragon chalks up picture-perfect docking at International Space Station – CBS News

Published

 on


Nineteen hours after a spectacular Florida launch, SpaceX’s Crew Dragon capsule caught up with the International Space Station early Sunday and glided in for a problem-free docking, bringing veteran astronauts Douglas Hurley and Robert Behnken to the outpost in SpaceX’s first piloted space flight.

The historic mission marks a major milestone in NASA’s push to end the agency’s sole reliance on Russian Soyuz spacecraft for carrying astronauts to and from the lab complex, the first piloted launch to orbit by a privately owned and operated spacecraft since the dawn of the space age.

“Welcome to Bob and Doug,” NASA Administrator Jim Bridenstine said to the crew in a call from mission control at the Johnson Space Center. “The whole world saw this mission, and we are so, so proud of everything you’ve done for our country and, in fact, to inspire the world.”

“We sure appreciate that, sir,” Hurley replied, floating in the space station’s Harmony module, flanked by crewmate Behnken, space station commander Chris Cassidy and Russian cosmonauts Anatoly Ivanishin and Ivan Vagner.

“It’s obviously been our honor to be just a small part of this,” he said. “We have to give credit to SpaceX, the Commercial Crew Program and, of course, NASA. It’s great to get the United States back in the crewed launch business, and we’re just really glad to be on board this magnificent complex.”

Following a picture-perfect climb to space Saturday atop a SpaceX Falcon 9 rocket, Hurley and Behnken monitored an automated rendezvous with the station Sunday, approaching the lab complex from behind and below.

Executing a precise series of thruster firings, the Crew Dragon looped up to a point directly in front of the station and lined up on the lab’s forward docking port, the same one once used by visiting space shuttles.

Hurley, a former Marine test pilot, briefly took over manual control, firing thrusters by tapping high-tech touch-screen cockpit displays to verify a crew’s ability to fly the spacecraft by hand if needed.

The ship’s flight computer than resumed the approach and the Crew Dragon’s docking mechanism engaged its counterpart on the space station at 10:16 a.m. ET, about 15 minutes ahead of schedule. A few minutes later, the capsule was pulled in and locked in place by 12 motorized latches.

Hurley and Behnken plan to bring the flag home at the end of their current mission.

Cassidy, a former Navy SEAL, followed naval tradition and rang the ship’s bell aboard the station to announce the Crew Dragon’s arrival.

“Dragon, arriving,” he said. “The crew of Expedition 63 is honored to welcome Dragon and the Commercial Crew Program to … the International Space Station. Bob and Doug, glad to have you as part of the crew. Well done. Bravo zulu.”

“We here at SpaceX are honored to have been part of ushering in this new era of human spaceflight,” said Anna Menon, the spacecraft communicator at SpaceX’s Hawthorne, California, control center. “On behalf of the SpaceX and NASA partnership, congratulations on a phenomenal accomplishment. And welcome to the International Space Station.”

During the post-docking welcome aboard ceremony, Republican Senator Ted Cruz of Texas asked the Crew Dragon astronauts “how does she handle?”

“It flew just like it was supposed to,” Hurley said. “We had a couple of opportunities to take it out for a spin, so to speak (flying manually), and my compliments to the folks back at Hawthorne and SpaceX for how well it flew. It’s exactly like the simulator, and we couldn’t be happier about the performance of the vehicle.”

Representative Brian Babin, a Texas Republican who represents the Johnson Space Center, asked the astronauts to describe their impressions of launching atop a Falcon 9 rocket.

Behnken, who flew twice aboard the space shuttle, recalled a fairly rough ride on the orbit while its two solid-fuel boosters were firing, but a smooth ascent after that with the shuttle’s three liquid-fueled engines.

He and Hurley expected the Falcon 9 ride to smooth out after the rocket’s first stage, powered by nine engines and generating 1.7 million pounds of thrust, was jettisoned about two-and-a-half minutes into flight. The Falcon’s second stage is powered by a single engine.

“We were surprised a little bit by how smooth things were off the pad,” Behnken said. “The space shuttle was a pretty rough ride heading into orbit with the solid rocket boosters, and our expectation was as we continued with (our) flight into second stage, that things would basically get a lot smoother than the space shuttle.

“But Dragon was huffin’ and puffin’ all the way into orbit, and we were definitely riding a Dragon all the way up,” he said. “So it was not quite the same ride, the smooth ride as the space shuttle was up to MECO [main engine cutoff], a little bit less Gs but a little bit more ‘alive’ is probably the best way I could describe it.”

The Crew Dragon is expected to remain docked to the station for six weeks to four months, allowing Behnken and Hurley to help Cassidy with a full slate of NASA and partner agency research and, possibly, with one or more spacewalks to install new solar array batteries and complete installation of a European experiment platform.

Cassidy said he looked forward to the help.

“We’ve got a few things to take care of tonight, make sure we’re all safe and we know the plan in case something bad happens,” he said, referring to a standard emergency briefing given to all newly arrived crew members.

“And then we’re looking forward to some operational stuff later in the month, maybe we’ll get outside and do some spacewalks. So we’re all super excited to have two more crewmates to the Expedition 63 team.”

NASA originally planned a short one-week to 10-day test flight for the first piloted Crew Dragon. But delays in the agency’s Commercial Crew Program and scaled-back production of Russian Soyuz spacecraft forced NASA to reduce the lab’s U.S. and partner agency crew to just one — Cassidy.

NASA managers are holding off on making a decision on when the Crew Dragon will return to Earth until they get a better idea of how atomic oxygen in the extreme upper atmosphere might affect the capsule’s solar cells.

No matter how that works out, engineers want time to thoroughly evaluate the capsule’s performance before proceeding with the first operational flight. NASA and SpaceX hope to launch that flight, carrying an international three-man one-woman crew, in the late August timeframe.

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.”
