Luna-25 crashes into the lunar surface and truncates Russia’s space programme

Published

 on

Russia’s Luna-25 probe has crashed into the Moon’s surface. Russia’s space agency, Roscosmos, has written it off as definitely lost and in pieces.

Dejection is widespread both among the Kremlin’s large space and political community and among ordinary Russians, for whom each new achievement of their own in the exploration of the cosmos helps to bolster national pride. Their grief is in stark contrast to the expressions of enormous joy expressed by Spaniards everywhere at the feat achieved by the women’s national football team in winning the World Cup in Australia.

President Vladimir Putin had every confidence in the success of the Luna-25 mission, the flagship mission chosen by Roscosmos to prove to the world that Russia is still a major space power. The probe was supposed to open the doors to Moscow’s revitalised lunar programme and reposition Lavochkin, his veteran scientific probe and satellite manufacturing company, at the global technological forefront.

However, the Russian spacecraft’s attempt to land on the Moon has ended in a resounding technical failure and the head of Lavochkin CEO Vladimir Kolmykov, in office since August 2017, hangs in the balance. Also at risk is the neck of Roscosmos director general General Yuri Borisov, who has been in the post for just 13 months.

Roscosmos has already officially confirmed the loss of Luna-25. The state news agencies Tass and Novosti reported on Sunday, 20 August, at 10:57 am Spanish time (11:57 am Moscow time) that “the Luna-25 automatic station has been destroyed after colliding with the surface of the moon”. Scientists from the Russian Space Research Institute (IKI) who were to take and analyse the samples obtained by the probe have been left without work.

The alert was sounded on Saturday, 19 August.

The first warning that things were not going according to plan came on Saturday, 19 August. The Roscosmos deputy director in charge of the mission, Alexander Ivanov, was urgently summoned and the agency issued a statement at 18:35. It said that, according to the flight programme, at 14:10 a “telecommand had been sent to the probe to activate the propulsion system that was to place it on an initial descent trajectory”.

But it added that, during the operation, there had been an “emergency” on board that “had not allowed the manoeuvre to be carried out in accordance with the established parameters”. It noted that the results of the preliminary analysis carried out by the mission monitoring and control technicians “suggest” that there had been a “deviation between the actual and calculated parameters” for the propulsion manoeuvre.

The following day, Sunday 20 August, at 09:47 Moscow time, Roscosmos pointed out that communications with the spacecraft had been interrupted the previous day since 14:57. The agency stressed that “all” measures taken since then to locate the spacecraft’s actual position and re-establish communications “have been unsuccessful”.

The Agency concluded that Luna-25 “entered the wrong orbit” and “ceased to exist after colliding with the surface of the Moon”. At the same time, it announced the appointment of an Interdepartmental Commission to determine the causes of the accident. And here ends the story of Luna-25, Russia’s first great bid in the 21st century to return to the surface of Selene.

PHOTO/IKI-Roscosmos – IKI’s scientific director, Professor Lev Zelyony, is one of the big disappointments. He had hoped that Luna-25 would be the first probe to land in the circumpolar region and detect the presence of water ice

The unofficial sources consulted say that “the ignition of the engine to correct the orbit prior to descent” took too long “due to a programming error”. As a result, according to unofficial sources, the spacecraft slipped out of its orbital position, plummeted and crashed to the moon’s floor. Roscosmos has not reported the height or speed of the probe at the time of the loss of control and communications.

All eyes on Chandrayaan-3

Luna-25 was intended to make a qualitative leap from academic research on the structure of the Earth’s natural satellite to the practical study of lunar water reserves. This is confirmed by IKI’s scientific director, Professor Lev Zelyony, who was confident that it would be “the first surface probe to land on the moon in the circumpolar region”.

Fortunately, before losing contact with the ground, the probe transmitted data from some of its science instruments and photographs of the Zeeman crater at the lunar South Pole back to Earth. Luna-25 was to land on the visible side of Bogulavsky Crater and conduct the first direct experiments “to detect the presence of water ice,” says Professor Zelyony.

PHOTO/Lavochkin-Roscosmos – The trajectory of Luna-25 was much more direct than Chandrayaan-3 on its way to the Moon. The Russian spacecraft launched on 11 August and was due to land on Monday, 21 August. The Indian spacecraft took off on 14 July and is due to arrive on Wednesday, 23 July.

The loss of Luna-25 clears the way for Chandrayaan-3 of the Indian Space Research Organisation, ISRO. The Asian country now has the opportunity to be the first to land on the lunar South Pole and become the fourth power to reach Selene’s soil. So far, all probes from the US, the former Soviet Union and China have landed on the near side and a few on the non-visible side of the moon.

Chandrayaan 3 was launched on 14 July and entered lunar orbit on 5 August. It has already executed a series of manoeuvres to slow down its speed for a soft landing, which is scheduled for 23 August at 21:34 GMT. Luna-25 was launched into space later – on 11 August – and was scheduled to land on Monday, 21 August. Essentially, the time difference lies in the longer trajectory of the Indian probe, which weighs 3.9 tonnes, compared to the more direct trajectory of Luna 25, which weighs 1.7 tonnes.

If India succeeds in landing on the South Pole, it will have demonstrated the potential of its space community – industrial, scientific and academic – and will be able to talk on equal terms with the United States, Russia and China and strengthen its presence in major international cooperation projects. On the one hand, with the Beijing-Moscow initiative to create a base on the lunar surface. On the other, with the manned programme and the NASA-led Artemis agreements to return astronauts to the moon’s soil.

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.”
