Artemis 2 astronauts flying to the moon could phone home with ham radio

Published

 on

It’s been 40 years since the first astronaut called an amateur radio operator on Earth. Now the moon is in the community’s sights.

Most of the astronauts aboard the Artemis 2 mission, which will send a quartet of people around the moon in late 2024, are certified ham radio (amateur radio) operators. There’s high hopes in the community that the astronauts may call home from deep space, the president of Radio Amateurs of Canada told Space.com.

“We feel it’s important that anyone, especially kids as they determine what they want to do with their life, have that opportunity” to talk with astronauts, Phil A. McBride said in a recent interview. After four decades of communication with low Earth orbit, he added, the hope is ham radio will reach further out with the moon.

The first ham radio operator in space was NASA astronaut Owen Garriott (W5LFL), who on Dec. 1, 1983 called Lance Collister (WA1JXN) in Frenchtown, Montana. A ham radio was even aboard the Russian space station Mir, according to NASA (opens in new tab), during the shuttle-Mir program that saw NASA astronauts visit the orbiting complex.

Today’s ham operators communicate with astronauts through Amateur Radio on the International Space Station (ARISS), largely aiming to let students directly talk with spaceflyers, according to documentation from the group (opens in new tab). As of 2022, NASA reports that more than 100 crew members (opens in new tab) have connected with 250,000 participants on the ground via ARISS.

It’s unclear if ham radio equipment will be onboard Artemis 2 as the mission manifest is not yet decided, Space.com confirmed with Chief Astronaut Joe Acaba and two of the crew members (NASA’s Reid Wiseman and the Canadian Space Agency’s Jeremy Hansen) in interviews last month. In theory, though, the main requirements would be adequate power and storage space for radio equipment, spare time for the crew to devote to the radio during their 10-day mission and a line of sight with Earth.

Three of the four Artemis 2 astronauts are certified hams, however, with call signs for Wiseman (KF5LKT), Hansen (KF5LKU) and NASA astronaut Victor Glover (KI5BKC). The other crew member, NASA astronaut Christina Koch, was studying for a 2019 amateur license exam when her record-setting one-year flight was abruptly rescheduled six months earlier than expected, according to the National Association for Amateur Radio (opens in new tab). Koch delayed the certification in favor of completing the mission training for her 328-day sojourn that ended on Feb. 10, 2020.

Participating in the ham community requires precious resources: Time to study for the required exams, equipment space to accommodate chatting with others and money to buy said equipment and obtain certification. Costs vary considerably by region. U.S. operators must pay around $70 to get their ham radio license from the Federal Communications Commission, according to Hamtronics.com (opens in new tab). Equipment costs can range from $30 handheld devices to more professional units that start at $400 and climb quickly into the thousands.

The community is an international collective that McBride says is quite welcoming of people from all ages, genders, backgrounds and all countries, to the extent that operators will often donate old equipment to those in need. That said, the barriers of cost and time do tend to favor males worldwide; detailed statistics on diversity are not easily available. Diversity and inclusion were the stated priorities of the American Radio Relay League in a December 2022 communique (opens in new tab) from its CEO, David Minster.

The ham community is starting to think past the apparent conclusion of the ISS program in 2030, to a time when commercial space stations are expected to begin. McBride said conversations are ongoing about bringing hams onto these commercial venues, although the planning for the outposts are still in early stages.

Speaking to his own experience, McBride said ham radio tends to inculcate valuable cross-disciplinary skills in the community. Math skills are a definite must, along with comfort with technology. McBride, 43, said as an example that his interest in ham radio had him studying algebra ahead of his schoolmates around ages 13 and 14.

“It encourages innovation,” McBride said of ham radio, which was estimated to have three million participants worldwide (opens in new tab) in 2015. The previous decade before that, based on U.S. statistics, appeared to show that number is growing.

The current ARISS collaboration involves all the major partners: NASA, the European Space Agency, Roscosmos and the Canadian Space Agency. Artemis will have a similarly international approach for its crews, so presumably, if ham radio is brought on board those missions several countries will be involved.

The astronauts themselves have said how much ham radio means to them. “I get choked up every time I read a report about a ham radio contact,” NASA astronaut Sunita Williams said in 2015 (opens in new tab).

“You go through the questions and it sounds like only 10 kids, then you read a report about how many people were at that event and how much preparation and time the kids took. It is nice to know it makes such a huge impact.”

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.”
