Russia’s Luna-25 Moon Lander Is Lost in a Crash – The New York Times

Published

 on


The robotic Luna-25 spacecraft appeared to have “ceased its existence” after a failed orbital adjustment, the space agency Roscosmos said.

A Russian robotic spacecraft that was headed to the lunar surface has crashed into the moon, Russia’s space agency said on Sunday, citing the results of a preliminary investigation a day after it lost contact with the vehicle.

It is the latest setback in spaceflight for a country that during the Cold War became the first nation, as the Soviet Union, to put a satellite, a man and then a woman in orbit.

The Luna-25 lander, Russia’s first space launch to the moon’s surface since the 1970s, entered lunar orbit last Wednesday and was supposed to land as early as Monday. At 2:10 p.m. on Saturday afternoon Moscow time, according to Roscosmos, the state corporation that oversees Russia’s space activities, the spacecraft fired its engine to enter an orbit that would set it up for a lunar landing. But an unexplained “emergency situation” occurred.

On Sunday, Roscosmos said that it had lost contact with the spacecraft 47 minutes after the start of the engine firing. Attempts to re-establish communications failed, and Luna-25 had deviated from its planned orbit and “ceased its existence as a result of a collision with the lunar surface,” Roscosmos said.

An interagency commission would be formed to investigate the reasons for the failure, it added.

Luna-25, which launched on Aug. 11, was aiming to be the first mission to reach the moon’s south polar region. Government space programs and private companies all over Earth are interested in that part of the moon because they believe it may contain water ice that could be used by astronauts in the future.

The main purpose of Luna-25 was to test technology for landing on the moon, and the loss of the lander during a less risky phase of the mission will add scrutiny to Russia’s space struggles.

For missions headed to the moon’s surface, the two most nerve-racking moments are the rocket launch from Earth and the landing itself. Three lunar landing attempts in the past four years — by India, an Israeli nonprofit and a Japanese company — all successfully maneuvered in orbit around the moon before failing during the last few minutes descending to the surface.

When missions are lost during orbital engine firings, the cause often turns out to be shoddy manufacturing and inadequate testing. Those shortcomings were the basis for the failure of Russia’s last major robotic interplanetary probe, Phobos-Grunt, in 2011. Another factor could be embarrassing human error, like when NASA’s Mars Climate Orbiter burned up in the Martian atmosphere in 1999 because of a mix-up between metric and imperial units.

Natan Eismont, a senior scientist of the Space Research Institute of the Russian Academy of Sciences, which led the scientific operations of Luna-25, said the spacecraft’s engine had not performed as designed during burns to adjust the spacecraft’s course.

“What I can say, and it was noticed by outside observers, that the correction somewhat deviated from what has been stated,” said Dr. Eismont, who said he was not directly involved with the mission.

This mission controllers “managed to cope with it successfully until the last maneuver,” Dr. Eismont said. But the last burn, to move Luna-25 to an orbit ahead of landing that passed within 11 miles of the surface, required a big push that did not go as planned. “Most likely the braking thrust was either too strong or it was in a wrong direction.”

Dr. Eismont suggested perhaps the mission managers should have taken more time.

“It’s up to the immediate participants to make these decisions” of proceeding toward landing or remaining in the circular orbit for further troubleshooting, he said. “They made their decision, and whether it was the correct decision, let a commission decide.”

The mission’s failure may be a blow to President Vladimir V. Putin, who has used Russian achievements in space as part and parcel of his hold on power.

That is part of the Kremlin’s narrative — a compelling one for many Russians — that Russia is a great nation held back by an American-led West that is jealous of and threatened by Russia’s capabilities. The country’s state-run space industry in particular has been a valuable tool as Russia works to remake its geopolitical relationships.

“The interest in our proposals is very high,” the head of Russia’s space program, Yuri Borisov, told Mr. Putin in a televised meeting in June, describing Russia’s plan to expand space cooperation with African countries. The initiative is part of the Kremlin’s overall efforts to deepen economic and political ties with non-Western countries amid European and American sanctions.

However, coverage of the Luna-25 mission had been muted, and remained that way after the spacecraft’s apparent crash.

The 6 p.m. newscast on Sunday night on state-run Channel 1, for instance, devoted only 40 seconds to Luna-25’s premature conclusion.

“By all appearances, the Luna-25 mission has ended,” the Channel 1 anchor said, before appending a positive note: “Scientists got invaluable information about the surface of the moon, among other things.”

The vaguely optimistic tone was echoed by Anatoly Petrukovich, also of the Space Research Institute which led Luna-25’s scientific operations.

“We are working on them,” Dr. Petrukovich said to the state-run Tass news agency, referring to upcoming lunar missions, “and hope that this work won’t be slowed down but accelerated.”

In recent decades, Russia’s exploration of Earth’s solar system has fallen a long way from the heights of the Soviet era.

The last unqualified success was more than 35 years ago, when the Soviet Union was still intact. A pair of twin spacecraft, Vega 1 and Vega 2, launched six days apart. Six months later, the two spacecraft flew past Venus, each dropping a capsule that contained a lander that successfully set down on the hellish planet’s surface, as well as a balloon that, when released, floated through the atmosphere. In March 1986, the two spacecraft then passed within about 5,000 miles of Halley’s comet, taking pictures and studying the dust and gas from the comet’s nucleus.

Subsequent missions to Mars that launched in 1988 and 1996 failed.

The embarrassing nadir came in 2011 with Phobos-Grunt, which was supposed to land on Phobos, the larger of Mars’ two moons, and bring back samples of rock and dirt to Earth. But Phobos-Grunt never made it out of Earth’s orbit. A few months later, it burned up in Earth’s atmosphere.

An investigation later revealed that Russia’s financially strapped space agency had skimped on manufacturing and testing, using electronics components that had not been proven to survive the cold and radiation of space.

Otherwise, Russia has been confined to low-Earth orbit, including carrying astronauts to and from the International Space Station, which it jointly manages with NASA.

Luna-25 was to have completed a one-year mission studying the composition of the lunar surface. It was also supposed to demonstrate technologies that would have been used in a series of robotic missions that Russia and lay the groundwork for a future lunar base that it is planning to build with China.

But the schedule for those missions — Luna 26, 27 and 28 — has already slipped years from the original timetable, and now there are likely to be further delays, especially as the Russian space program struggles, financially and technologically, because of sanctions imposed after Russia’s invasion of Ukraine.

Roscosmos will face a difficult decision of whether to redo the Luna-25 mission or leave the landing technology untested for now and move on to more ambitious follow-on missions. If Russia decides to re-fly Luna-25, that will likely add even more years of delay.

Although NASA and the European Space Agency continue to cooperate with Russia on the I.S.S., other joint space projects ended after the invasion of Ukraine. For the lunar missions, that means Russia needs to replace key components that were to come from Europe.

Russia has struggled to develop new space hardware, especially electronics that reliably work in the harsh conditions of outer space.

“You cannot really fly in space, or, at least, fly in space for a long time, without better electronics,” said Anatoly Zak, who publishes RussianSpaceWeb.com, which tracks Russia’s space activities. “The Soviet electronics were always backwards. They were always behind the West in this area of science and technology.”

He added: “The entire Russian space program is actually affected by this issue.”

Other ambitious Russian space plans are also behind schedule and will likely take much longer than the official pronouncements to complete.

Angara, a family of rockets that has been in development for two decades, has only launched six times.

A few days ago, Vladimir Kozhevnikov, the chief designer for Russia’s next space station, told the Interfax news agency that Oryol, a modern replacement for the venerable Soyuz capsule, would make its maiden flight in 2028.

Back in 2020, Dmitry Rogozin, then the head of Roscosmos, said that the maiden flight of Oryol would take place in 2023 — meaning that, in just three years, the launch date has slipped five years.

Another country, India, will now get the chance to land the first probe in the lunar south pole’s vicinity. Its Chandrayaan-3 mission launched in July, but it opted for a more roundabout but fuel-efficient route to the moon. It is scheduled to attempt a landing on Wednesday.

“It’s unfortunate,” Sudheer Kumar, a spokesman for the Indian Space Research Organization, said about the Russian lander’s crash. “Every space mission is very risky and highly technical.”

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.”
