SpaceX launches next-generation Dragon cargo ship to space station – CBS News

Published

 on


A SpaceX Falcon 9 rocket boosted a next-generation SpaceX cargo ship into orbit Sunday, the first in a new line of roomier, more capable Dragon capsules featuring many of the more advanced systems used by the company’s Crew Dragon astronaut ferry ships.

Making the company’s 21st supply run to the International Space Station — the first under a follow-on NASA contract — the new Cargo Dragon was loaded with more than 6,500 pounds of crew supplies, spare parts, science gear and other equipment, including a commercial airlock for on-board experiments.

Unlike the original Dragon cargo ship, which had to be captured by the space station’s robot arm for berthing, the Dragon 2 is designed to fly itself all the way to docking at the same ports used by piloted Crew Dragon spacecraft. Unlike the crewed version, however, the cargo ship is not equipped with seats or an emergency abort system.

Running a day late because of bad weather, the long-awaited mission began at 11:17 a.m. EST when the Falcon 9’s nine first stage Merlin 1D engines roared to life with a torrent of flame, pushing the 229-foot-tall rocket away from pad 39A at the Kennedy Space Center.

It was the 24th Falcon 9 launch so far this year, the 101st since the rocket’s debut in 2010, the 21st SpaceX ISS cargo launch and the first for a Dragon 2 capsule.

Accelerating on 1.7 million pounds of thrust, the rocket quickly arced away to the northeast, climbing directly into the plane of the space station’s orbit — a requirement for spacecraft trying to catch up and dock with a target moving at nearly 5 miles per second.

Two-and-a-half minutes after liftoff, now well out of the thick lower atmosphere, the first stage, making its fourth flight, fell away and flew itself to a landing on a downrange SpaceX droneship. It was SpaceX’s 68th successful booster recovery and its 47th at sea.

The Falcon 9’s second stage, meanwhile, continued the climb to space, releasing the Dragon 2 capsule into the planned preliminary orbit 12 minutes after launch. If all goes well, the capsule will rendezvous with the station Monday, guiding itself in for a docking at the upper port of the forward Harmony module around 1:30 p.m.

The space station is equipped with eight docking ports, four used by Russian spacecraft and four on the forward end of the lab that are available for U.S. cargo and crew ships. Two of the U.S. ports are used by visiting cargo ships that need the station’s robot arm to pull them in for berthing.

The other two U.S. ports, however, are equipped with docking mechanisms that can accommodate automated linkups by SpaceX crew and cargo Dragons and Boeing’s CST-100 Starlink crew ferry ship. The Crew Dragon spacecraft that carried four astronauts to the station last month is docked at Harmony’s forward-most port while the Dragon 2 cargo ship will carry out the first docking at the module’s upper space-facing port.

SpaceX won NASA contacts valued at $3.04 billion for 20 space station resupply flights through 2020 using the original Dragon cargo ship design and contracts for an unspecified amount covering at least nine additional flights through 2024 using the Dragon 2 spacecraft. The capsule launched Sunday is the first of those.

SpaceX also holds a $2.6 billion NASA contract to build and launch the piloted Crew Dragon capsule to ferry astronauts to and from the space station. So far, three Crew Dragons, two with astronaut crews and one without, have docked at the station.

For its maiden flight, the Dragon 2 cargo ship’s pressurized cabin was loaded with 803 pounds of crew supplies; 2,100 pounds of science gear; 265 pounds of spacewalk equipment; 698 pounds of vehicle hardware; 102 pounds of computer equipment; and 53 pounds of Russian hardware.

Stored in the capsule’s unpressurized trunk section was a 2,400-pound airlock developed by Nanoracks, a company that facilitates flights by private industry, university and government-sponsored experiments. The airlock will be attached to the Tranquility module’s far left port and periodically detached, exposing experiments inside and mounted on its exterior to the vacuum of space.

The station already features a Japanese experiment airlock, but the Nanoracks unit, known as the Bishop Airlock, is about five times larger, said project manager Brock Howe.

“There are a lot of different environments that the scientists can use, a lot of different volumes, a lot of different payload power and data capabilities on board the airlock that really will enhance their ability to do some really cool science,” he said.

Other equipment on board the Dragon 2 includes parts for the lab’s recently delivered female-friendly next generation toilet, gear for the station’s water recycling system, a nitrogen tank for cabin repressurization and a rodent habitat with research specimens.

Among the experiments being delivered are two designed to study how microgravity affects heart and brain tissue and another called “BioAsteroid” that will probe the role microbes might play in future space mining operations.

“BioAsteroid is an experiment to study whether we can use micro organisms, bacteria or fungi, to extract economically interesting elements from asteroid material,” said principal investigator Charles Cockell, professor of astrobiology at the University of Edinburgh.

“It’s essentially what we would call a bio-mining experiment, and we hope to learn whether we can use microbes to extract things like rare earth elements and other elements that can be used to sustain a self sustaining human presence throughout the solar system.”

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.”
