House introduces NASA authorization bill

Published

 on

WASHINGTON — The leadership of the House Science Committee introduced a NASA authorization bill Jan. 24 that seeks to significantly alter NASA’s current plans to return humans to the moon and make them part of an effort to send humans to Mars.

The bill, designated H.R. 5666 and introduced by Rep. Kendra Horn (D-Okla.), chair of the committee’s space subcommittee, seeks to put a human return to the moon within the context of a larger “Moon to Mars” program that would no longer have the goal of returning humans to the surface of the moon by 2024, as Vice President Pence announced in March 2019.

“The Moon to Mars program shall have the interim goal of sending a crewed mission to the lunar surface by 2028 and a goal of sending a crewed mission to orbit Mars by 2033,” the bill states.

NASA’s current plans for returning to the moon call for the development of a lunar Gateway in orbit around the moon, which would serve as a staging area for expeditions to the lunar surface. The bill would instead call this facility the “Gateway to Mars,” and allow it to be based elsewhere in cislunar space. The Gateway would also not be required to support lunar landings.

NASA last fall solicited proposals for its Human Landing System program, where the agency would support development of one or two commercial landers, buying landing services from those companies. While companies had the option of not using the Gateway for an initial landing, the Artemis 3 mission in 2024, the agency stated that the Gateway would ultimately be used to aggregate lunar lander elements.

The bill would direct NASA to have “full ownership” of a lunar lander rather than buy services from companies. It would also require at least one uncrewed and one crewed test flight of the lander, something not explicitly required by NASA in its current plans.

Moreover, the bill directs NASA to develop a human lunar lander “as an integrated lunar landing system carried on an Exploration Upper Stage-enhanced Space Launch System,” known as SLS Block 1B. That suggests a design that most closely resembles one proposed by Boeing, who proposed launching an integrated lander on a single SLS, rather than using commercial launch vehicles to launch lander elements that are then aggregated at the Gateway.

While the bill would direct NASA to perform at least two crewed lunar landings a year, the bill makes clear the agency’s activities at the moon would primarily be those required to support a later human mission to Mars. The bill directs NASA to identify “the minimum set of human and robotic lunar surface activities that must be completed to enable a human mission to Mars” and how NASA will complete those activities within five years of the first crewed landing under the program.

In particular, the bill deemphasizes plans to make use of resources like lunar ice at the moon, something NASA has argued is vital since rolling out the Artemis program. NASA is developing a rover called VIPER that would launch in 2022 to study water ice deposits in permanently shadowed craters at the south pole of the moon, a precursor for future human missions there.

“Lunar in-situ resource utilization shall not be considered as risk reduction for the initial crewed missions to orbit and land on Mars,” the bill states. Such activities “shall not be included in the Moon to Mars Program and shall be budgeted separately from the Moon to Mars Program.” The bill similarly restricts any development of a “continuously crewed lunar outpost or research station.”

“Americans should be the first to set foot on the Red Planet, and H.R. 5666 moves us closer to that goal by directing a steady and sustainable course of action,” Horn said in a statement announcing the bill’s introduction.

The bill’s cosponsors include Rep. Eddie Bernice Johnson (D-Texas), chair of the House Science Committee, as well as Reps. Frank Lucas (R-Okla.), ranking member of the full committee and Brian Babin (R-Texas), ranking member of the space subcommittee. “Space should not be a partisan issue, and I am proud of the across-the-aisle teamwork which made this legislation possible,” Horn said in the statement.

“The NASA Authorization Act of 2020 supports the Administration’s bold space exploration goal to return to the Moon and go on to Mars while maintaining NASA’s other important science and aeronautics work,” Babin said in the same statement.

The 102-page bill covers the full gamut of NASA’s activities. Another section of the bill would extend NASA’s authorization to extend the International Space Station from 2024 to “at least 2028.” Other sections endorse a diverse range of NASA science missions, including those like the Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) and Climate Absolute Radiance and Refractivity Observatory (CLARREO) Pathfinder missions that the administration has sought to cancel in recent NASA budget requests. The bill also endorses a range of planetary defense programs related to potential hazardous near Earth objects, as well as the search for “technosignatures” from extraterrestrial civilizations.

The House space subcommittee is scheduled to mark up the bill Jan. 29. The full committee would then take up the bill before going to the full House. Any NASA authorization bill that passes the House would have to be reconciled with a Senate bill introduced in November that seeks far fewer changes to NASA’s exploration programs.

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.”
