SpaceX transferred the first astronaut-ready Crew Dragon spacecraft Friday night from a fueling facility at Cape Canaveral Air Force Station to pad 39A at NASA’s Kennedy Space Center, where teams will join the capsule with its Falcon 9 launcher for liftoff later this month.

The spacecraft arrived at the pad 39A hangar late Friday night, according to Kyle Herring, a NASA spokesperson.

Before its transport by road to the Falcon 9 hangar, the Crew Dragon capsule’s propulsion system was loaded with hypergolic hydrazine and nitrogen tetroxide propellants inside a fueling complex a few miles south of pad 39A at Cape Canaveral Air Force Station.

The propellants will feed the Crew Dragon’s Draco in-space maneuvering thrusters and high-performance SuperDraco escape engines, which would only be activated in the event of an emergency during launch.

Liftoff of the Crew Dragon test flight — the first U.S. mission to send astronauts to Earth orbit since 2011 — remains scheduled for May 27 at 4:33 p.m. EDT (2033 GMT) to kick off a 19-hour pursuit of the International Space Station.

In the coming days, SpaceX ground crews will verify mechanical and electrical attachments between the Crew Dragon spacecraft and the Falcon 9 launcher inside the hangar. Then the entire vehicle, measuring some 215 feet (65 meters) tip to tail, will be lifted by a crane and placed onto SpaceX’s rocket transporter for the quarter-mile journey up the ramp to the deck of pad 39A.

The Falcon 9 launcher assigned to the Crew Dragon’s first piloted test flight — designated Demo-2 or DM-2 — is an all-new vehicle. SpaceX regularly lands and reuses rocket boosters to cut costs, but NASA has required SpaceX to assign new first stages to at least the initial launches that carry astronauts.

The first stage booster for the Crew Dragon’s Demo-2 mission is emblazoned with NASA’s “worm” logo, which spells out “NASA” in stylized lettering. The worm logo was introduced in 1975 to add a touch of modernity to the agency’s public image after the last of NASA’s Apollo moon landings, which took place when NASA used its original blue “meatball” symbol.

The worm logo was retired in 1992, and NASA removed the iconic interconnected lettering from signs, brochures, and even the agency’s space shuttles. The original meatball, first designed in the late 1950s, again became NASA’s official logo.

“The worm is back,” NASA announced last month. “And just in time to mark the return of human spaceflight on American rockets from American soil.”

In a statement, NASA said “the retro, modern design of the agency’s (worm) logo will help capture the excitement of a new, modern era of human spaceflight.”

The memorable worm insignia — with its stark red logotype — will make its first public appearance on a NASA-sponsored rocket in nearly 30 years when the Falcon 9 launcher emerges from the hangar next week and rolls out to pad 39A.

Once the vehicle is vertical on the launch pad, SpaceX will run the Falcon 9 rocket through a fueling test and a test-firing of its Merlin main engines next week.

At the same time ground teams work on flight hardware at Cape Canaveral, NASA astronauts Doug Hurley and Bob Behnken are in quarantine at their homes in Houston before they travel to the Kennedy Space Center on Wednesday aboard a NASA Gulfstream jet.

The astronauts are both veterans of two space shuttle flights, and they started working full time on NASA’s commercial crew program in 2015. In 2018, NASA assigned Hurley and Behnken to the Crew Dragon’s first flight with astronauts.

After arriving at the spaceport in Florida on May 20, the astronauts will receive mission briefings, brush up on procedures, and perform fit checks with their SpaceX-made launch and entry flight suits. They are also scheduled to take questions from reporters in a press conference Wednesday at Kennedy soon after they arrive in Florida, then in a virtual news briefing Friday, May 22.

If activities next week go according to plan, the astronauts will run through a launch day dress rehearsal next Saturday, May 23.

The two-man crew will suit up and ride inside a Tesla Model X from the Operations and Checkout Building at Kennedy to launch pad 39A, where they will ride an elevator to the 265-foot-level of the pad’s fixed tower. They will then walk across SpaceX’s crew access arm to the white room, where a closeout team will help them board the capsule.

Hurley, the 53-year-old Dragon spacecraft commander, will strap into the left seat of the capsule. Behnken, 49, will take his place in the right seat for the pre-launch simulation.

The “dry dress rehearsal” is meant to give the astronauts and their support teams a feel for the flow of launch day.

Amid the hardware preps and crew activities, NASA and SpaceX managers plan to convene a pair of major reviews before the Crew Dragon launch to ensure the spacecraft, the rocket, the astronauts, ground systems and the International Space Station are ready for the test flight.

A Flight Readiness Review is scheduled May 21, followed by a Launch Readiness Review May 25.

“There’s still work to be done,” said Phil McAlister, head of NASA’s commercial spaceflight development mission. “We’re still finishing up some final testing. There’s still some documents we have to review.”

“The Flight Readiness Review on the 21st is a very big milestone,” McAlister said Thursday in a briefing to the NASA Advisory Council’s Human Exploration and Operations Committee. “That’s going to be when we we all get together one last time and say whether we are ready for flight. So that will be a huge, huge milestone.”

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.”
