NASA’s New Budget for Artemis? $28 Billion – Universe Today

Published

 on


It’s no exaggeration to say that NASA’s plans to return astronauts to the Moon has faced its share of challenges. From its inception, Project Artemis has set some ambitious goals, up to and including placing “the first woman and next man” on the Moon by 2024. Aside from all the technical challenges that this entails, there’s also the question of budgets. As the Apollo Era taught us, reaching the moon in a few years doesn’t come cheap!

Funding is an especially sticky issue right now because of the fact that we’re in an election year and NASA may be dealing with a new administration come Jan of 2021. In response, NASA announced a budget last week (Mon. Sept 21st) that put a price tag on returning astronauts to the Moon. According to NASA, it will cost taxpayers $28 billion between 2021 and 2025 to make sure Project Artemis’ meets its deadline of 2024.

On the same day during a phone briefing with journalists, NASA Administrator Jim Bridenstine noted that “political risks” are often the biggest obstacle to NASA’s work. This is perhaps a reference to the fact that NASA’s plans and goals have forcible shifted over the past decade or so in response to the changing priorities of new administrations.

When he took office in 2009, President Obama and his cabinet inherited the Constellation Program initiated by the Bush administration in 2005. This program aimed to create a new generation of launch systems and spacecraft to return astronauts to the Moon by 2020 at the latest. However, due to the then-current economic crisis and recommendations that the 2020 deadline could not be reached, it was canceled.

A year later, the Obama administration initiated NASA’s “Journey to Mars,” which picked up much of Constellation’s architecture but shifted the focus to a crewed mission to Mars by the 2030s. By 2017, VP Pence announced that the Trump administration’s focus would be on returning to the Moon within the 2020s. By March of 2019, Project Artemis was officially unveiled and NASA was charged with returning to the Moon in five years.

Approval for this funding now falls to Congress, which will be looking at elections by November 3rd. This year, in addition to deciding who will be president, 434 of the 435 Congressional districts across all 50 US states and 33 class 2 Senate seats will be contested. Come January, NASA could be dealing with an entirely new government.

According to Bridenstine, the first tranche of funding ($3.2 billion) must be approved by Christmas in order for NASA to remain “on track for a 2024 moon landing.” In total, NASA will require a full $16 billion in order to fund the development of the human landing system (HLS) – aka. a lunar lander – that will allow the crew of the Artemis III mission (one man and one woman) to land on the surface of the Moon.

At present, three major companies are competing to see which of their concepts NASA will choose. They include SpaceX, which presented NASA with a modified version of their Starship designed, altered to accommodate lunar landings. Then there’s Alabama-based Dynetics’ Human Landing System (DHLS), a vehicle that will provide both descent and ascent capabilities.

Rounding out the competitors is Blue Origin, meanwhile is collaborating on a design for an Integrated Lander Vehicle (ILV) that will consist of three elements – the descent, transfer, and ascent elements – designed by Blue Origin, Northrop Grumman, and Lockheed Martin, respectively. The winning design will either be integrated with the Orion capsule carrying the crew to the Moon or will launch on its own atop a company rocket.

Bridenstine also took the opportunity to set the record straight regarding where the Artemis III mission would be landing. This was in response to a previous statement he made during an online meeting of the Lunar Exploration Analysis Group (LEAG), which seemed to hint that the Artemis crews might revisit the Apollo sites.

“If you’re going to go to the equatorial region again, how are you going to learn the most?” he said. “You could argue that you’ll learn the most by going to the places where we put gear in the past. There could be scientific discoveries there and, of course, just the inspiration of going back to an original Apollo site would be pretty amazing as well.”

During Monday’s phone briefing, however, Bridenstine emphasized that the mission will be heading to the South Pole-Aitken Basin:

“To be clear, we’re going to the South Pole. There’s no discussion of anything other than that. The science that we would be doing is really very different than anything we’ve done before. We have to remember during the Apollo era, we thought the moon was bone dry. Now we know that there’s lots of water ice and we know that it’s at the South Pole.”

Investigations of this ice and other resources will be intrinsic to long-term plans to create the Artemis Base Camp. The current schedule has the Artemis I flight (which will be uncrewed) taking place by November of 2021. This will be the inaugural flight of NASA’s Space Launch System (SLS) flying with the Orion space capsule. Artemis II is scheduled for 2023, and will take a crew of astronauts around the Moon but will not attempt a lunar landing.

In 2024, the long-awaited Artemis III mission will occur and will see astronauts land on the surface for a week of operations and up to five operations on the surface. Beyond 2024, NASA plans to deploy the various segments that make up the Lunar Gateway, which will facilitate more long-term missions to the lunar surface and allow for the construction of the Artemis Base Camp.

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.”
