Artemis 1: Everything you need to know about the launch of NASA’s first Moon mission in 50 years – Euronews

Published

NASA’s giant Space Launch System (SLS) rocket is set to blast off on a journey to the Moon, a mission the US space agency says will lay the foundations for a long-term presence on the lunar surface.

The Artemis 1 mission is a test flight of massive importance. The launch, scheduled for Monday, will see an unmanned Orion module put into orbit around the Moon before returning to Earth.

It will gather crucial data ahead of the next stages in the mission – a manned launch of the Orion module to lunar orbit, followed by the first mission to land humans on the Moon since 1972.

Here’s what you need to know ahead of Monday’s launch.

What is Artemis 1?

This is the first stage of the Artemis mission, which has the ultimate goal of establishing a long-term presence on the Moon’s surface.

The stage is set on Monday for the start of the Artemis I mission. NASA will launch an unmanned Orion spacecraft into orbit around the Moon on a test run to ensure manned missions are as safe as possible.

The Orion spacecraft is being launched from the Kennedy Space Center in Florida on NASA’s giant rocket called the SLS.

It is, according to NASA, the world’s most powerful rocket, able to carry more payload into deep space than any other vehicle.

Standing at almost 100 m tall, the SLS can deliver 4 million kg of thrust. Two minutes into launch, two boosters will detach from the rocket, followed by the core stage (which acts as the backbone of the rocket, doing most of the heavy lifting).

These parts will fall into the Pacific Ocean, as the Orion spacecraft continues on course toward the Moon.

Orion will travel 450,000 km from Earth, and thousands of kilometres beyond the Moon over the course of the four to six-week mission.

“We’re going to stress it and test it. We’re going to make it do things that we would never do with a crew on it in order to try to make it as safe as possible,” NASA Administrator Bill Nelson said on Wednesday.

Orion will be propelled towards the Moon by a service module provided by the European Space Agency (ESA).

Flight test dummies

The Orion spacecraft, which is 3 m tall, can seat four astronauts.

A full-size dummy in an orange flight suit is going to occupy the commander’s seat for this flight, rigged with vibration and acceleration sensors.

Two other mannequins made of material simulating human tissue will measure cosmic radiation, which is one of the biggest risks of spaceflight.

The flight will also see ten shoebox-sized satellites pop off the capsule once it is en-route to the Moon, which will measure radiation, amongst other things.

What happens after Artemis 1?

After Artemis I comes Artemis 2 and 3, NASA’s first manned lunar missions in five decades.

Assuming everything goes to plan with the first test mission, and the next missions aren’t hit by the same delays that plagued Artemis 1, a second test flight around the Moon – this time manned – is scheduled for 2024.

If that goes to plan, Artemis 3 should go ahead a year later. This will be the first crewed lunar landing since Apollo 17 in 1972. It is also intended to be the first mission to land a woman on the Moon.

The missions will involve testing the systems needed to establish a gateway base in orbit around the Moon, which would be the base for lunar surface missions. With a long-term presence established on or around the Moon, it would then be used for future missions further afield, including to Mars.

“This wasn’t a one or two-person job. This was teams of hundreds of people that came in from different backgrounds, different experiences that all made this happen together,” said Nicholas Nugent, a project engineer at Stennis Space Center.

“We’re about to launch the rocket that these people built. How cool is that? You can say ‘I worked on that rocket’ and they’re working on the second one and the third one and fourth one and the fifth one,” said Lonnie Dutreix, director of Michoud Assembly Facility in New Orleans.

How much did this all cost?

The Artemis missions have been beset by delays and technical faults, so there is a lot of pressure on Monday’s launch.

The cost of Artemis 1 has spiralled to $4 billion (€4 billion), and the entire programme will have set NASA back at least $93 billion (€93 billion) by the time astronauts land once again on the Moon.

“This is a test flight, all right and it’s not without risk. We have analysed the risk as best we can, and we’ve mitigated also as best we can,” Bob Cabana, NASA’s Associate Administrator, said ahead of the launch.

“But we are stressing Orion beyond what it was actually designed for. In preparation for sending it to the moon with a crew and we want to make sure that it works absolutely perfectly when we do that and that we understand all the risks. We’re going to learn a lot from this test flight”.

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.”
