We’re Going To Uranus! NASA Will Spend $4.2 Billion And $4.9 Billion On New Flagship Missions To The ‘Ice Giant’ And Saturn’s ‘Wet Moon’ Enceladus – Forbes

It’s official—NASA is being sent to orbit the seventh planet Uranus and land on Saturn’s moon Enceladus.

It should arrive at these two distant targets in 2045 and 2050, respectively.

The National Academy of Sciences today finally published its Decadal Survey for Planetary Science and Astrobiology. It’s regarded as both a “wish list” for planetary scientists and a “to do” list for NASA.

It also includes the expected instruction to NASA to go get the samples of Martian rock currently being collected by the Perseverance rover, but this Mars Sample Return mission must not be allowed to “undermine the the long-term programmatic balance of the planetary portfolio.”

In other words, NASA is going to send a fully-equipped orbiter—with an atmospheric probe to dive beneath its clouds—to Uranus. The report says it should be NASA’s highest priority large mission for the next decade and $4.2 billion.

However, time is tight. The position of Jupiter means it would need to launch in 2031 or 2032 on a SpaceX Falcon Heavy rocket to arrive at Uranus in 2044 or 2045. The cloudy planet has not been visited since Voyager 2 made a brief flyby in 1986.

“Today we’re one step closer to seeing that ambitious orbital mission to an “ice giant” system that we’ve been working towards for so long,” said Professor Leigh Fletcher of the School of Physics and Astronomy at the University of Leicester, and a member of the Giant Planets panel for this survey.

Fletcher added that he felt “elation, relief, pride in the team that made this happen, and a little trepidation about the road ahead.”

It’s the second Decadal Survey in a row that a mission to the “ice giant” has been recommended. However, last time it Uranus was the third priority after the Perseverance rover already on Mars and Europa, which is on the cusp of launch. Now Uranus is top priority.

The report also says that the Enceladus Orbilander should be NASA’s second-highest priority large mission. This mission to orbit and land on Saturn’s tiny active moon—which has a an ocean underneath an icy crust—will investigate the plumes spilling into space from cracks in its icy surface. It could launch in 2038 and arrive in 2050—and cost $4.9 billion.

The missions complement each other because scientists will be able to compare the moons of Uranus—some of them thought to be ocean worlds—with Enceladus.

Since the Mars Sample Return mission to go collect the Perseverance rover’s rock samples is already being planned by NASA it was thought that Uranus would likely miss out on a full flagship mission, instead being commuted to a cheaper flyby mission.

“This larger mission can deliver an atmospheric probe, as well as get into orbit at Uranus,” said Amy Simon, senior scientist for Planetary Atmospheres Research in the Solar System Exploration Division at the NASA Goddard Space Flight Center, and a member of the committee that prepared the report. “This allows for detailed study of the atmosphere, the gravity field and the magnetic field, as well as a several year tour of the moons.”

Planetary scientists that specialize in Uranus and the outer solar system are excited.

“It’s the culmination of 15 years of research, white papers, mission proposals, and international meetings,” said Fletcher. “The science case has only improved with time, particularly as Ice-Giant-sized worlds (or slightly smaller) appear commonplace in the pantheon of exoplanets … this decadal survey prioritisation is a wonderful leap forward for the outer solar system community.”

“This is excellent news—the Uranian system is fascinating and still poorly understood,” said Dr. Richard Cartwright, a planetary scientist and astronomer at NASA Ames Research Center and lead author of a white paper proposing a Uranus Orbiter. “Uranus’ moons are candidate ocean worlds that may have harbored life in the past.”

He says that a close-up exploration of Uranus’ five large moons—Miranda, Ariel, Umbriel, Titania and Oberon—with a full suite of scientific instruments on a flagship orbiter would help scientists determine whether they are like the the ancient ocean world of Ceres or the active ocean world Enceladus.

“A flagship mission to the Uranian system will provide an incredible opportunity to explore how ice giant systems, which are common in the galaxy, formed and evolved,” said Dr. Chloe Beddingfield, a planetary scientist and astronomer at NASA Ames Research Center, leading expert on Uranian moon geology and lead author of a white paper on the exploration of “ice giants” considered by the report. “This opportunity will allow us to address fundamental questions including how Uranus migrated through the solar system and whether the large moons are ocean worlds that may harbor life.”

Whether the report’s recommendations come to fruition depend largely on NASA’s budget—and that could spell trouble for the Enceladus Orbilander. Though it’s now ranked as NASA’s second-highest priority large mission costing around $2 billion, the report also says that if the budget doesn’t permit than NASA should instead consider an Enceladus Multiple Flyby mission, a pared-down, more affordable fly-by concept costing under $900 million.

“When we generate a Decadal Survey, we do not know what the budget will be over that ten years, and there are many pulls on the funding,” said Simon. “While we’d like two new Flagships to be started in the decade, that may or may not be affordable, so allowing Enceladus to remain in New Frontiers allows extra flexibility.”

Compiled by scientists at the cutting edge of their fields and specifically designed to be fair and honest, the Decadal Survey will set out the priorities for NASA for the next 10 years. Congress usually follows its recommendations.

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.”
