Odysseus moon lander tipped over onto its side during touchdown, company says – CBS News

Published

 on


Intuitive Machines’ Odysseus moon lander, coming down faster than expected and moving slightly to one side at the moment of touchdown Thursday, apparently caught a footpad on the lunar surface and tipped over onto its side, officials said Friday.

Telemetry indicates the top of the spacecraft may be resting on a rock or the lander could be tipped over on upward-sloping terrain. But Steve Altemus, CEO and co-founder of Intuitive Machines, said Odysseus is still able to draw power from the sun and send engineering and science data back to Earth.

Engineers are in the process of downloading data and hope to downlink stored images as early as this weekend clarifying the orientation of the 14-foot-tall spacecraft.

“We’re downloading and commanding data from the buffers in the spacecraft and trying to get you surface photos because I know that everyone’s hungry for those,” Altemus said.

Steve Altemus, Intuitive Machines CEO and co-founder, uses a model of the company’s Odysseus moon lander to illustrate how the spacecraft likely tipped over during touchdown Thursday. Based on telemetry, it appears the lander’s top section may be resting on a rock (the small blue model). It’s also possible the spacecraft tipped over on sloping terrain or even caught one of its foot pads in a crevice.

In the meantime, all the lander’s active instruments, provided by NASA and commercial customers, are facing away from the lunar surface and should be able to return data as planned. But it likely will take longer than expected given some of the tilted spacecraft’s antennas do not face Earth.

And there’s not much time. Regardless of the tip over, the sun will drop below the horizon at the landing site in a little more than one week, ending power generation by the lander’s solar cells. That was always in the cards.

The spacecraft is not designed to withstand the ultra-low temperatures of the lunar night and while flight controllers will attempt to recontact the probe when the sun rises again, they do not expect Odysseus to answer.

“Three major accomplishments”

All that said, Joel Kearns, NASA’s deputy associate administrator for exploration, praised Intuitive Machines for its off-kilter but still-successful landing.

“Let me congratulate Intuitive Machines for three major accomplishments,” he said. “The first is for having the first successful soft landing on the moon by the United States since 1972. The second is for being the first non-government commercial organization to actually touch down safely.

“And the third is for having a touchdown point at 80 degrees south latitude, much closer to the south pole of the moon than any earlier U.S. robotic or human explorers.”

That’s important to NASA, which plans to send Artemis astronauts to the south polar region in the next several years to looks for possible ice deposits while establishing a long-term presence on the moon.

On Saturday, President Joe Biden commented on the milestone in a statement that congratulated NASA and the Intuitive Machines team.

“America does hard things,” the statement read. “We rise to the great scientific challenges of our time. And there’s nothing beyond our capacity when we work together.”

Odysseus was partially funded by NASA’s Commercial Lunar Services Payloads program, designed to encourage private industry to develop transportation capabilities that the agency can then use to transport payloads to the moon.

NASA paid Intuitive Machines $118 million to carry six payloads to the moon aboard Odysseus.

Launched Feb. 15 by a SpaceX Falcon 9 rocket, Odysseus braked into orbit around the moon Wednesday. Flight controllers subsequently raised the orbit slightly to correct a slight targeting error and were gearing up for landing when they ran into problems with a sensor package needed to help fine-tune the trajectory to touchdown.

Luckily for Intuitive Machines, one of the six NASA payloads on board Odysseus was intended to test a different type of navigation sensor, an instrument known as NDL, which stands for Navigation Doppler Lidar.

The NDL system operates like a radar but captures reflected laser light instead of radio waves to precisely measure vehicle velocity, direction and altitude.

Odysseus was commanded to make an additional orbit of the moon while engineers hurriedly wrote and tested software patches to integrate the NASA system into the lander’s navigation algorithms.

“That’s what allowed them to be successful,” NASA Administrator Bill Nelson told CBS News Thursday night. “It was a NASA payload that saved the day. (But) don’t take anything away from Odysseus and Intuitive Machines, because this is the first commercial lander to be able to pull off this feat.”

As Odysseus closed in on its landing site, it pitched up from horizontal to a vertical orientation for the final descent to touchdown. The flight plan called for the spacecraft to land with a purely vertical velocity of just 2 mph, roughly a moderate walking pace.

Because of the unexpected lateral velocity, however, engineers believe one of the lander’s six footpads either hit a rock or got caught in a crevice, causing the spacecraft to tip over.

Base on telemetry, “it has to be somewhat elevated off the surface horizontally, so that’s why we think it’s on a rock or the foot is in a crevice or something to hold it in that attitude,” Altemus said.

The revelation that Odysseus had tipped over on touchdown came as a surprise following an overnight update from Intuitive Machines saying telemetry indicated the spacecraft was in an upright orientation. Altemus said Friday that conclusion was based on “stale data.”

A more through analysis of residual propellant and data from inertial measurement units indicating the direction of gravity showed the spacecraft was, in fact, resting on its side.

The landing highlighted the risks faced by any robotic spacecraft attempting to land on unknown terrain and the challenge of autonomously navigating around rocks and other obstacles that cannot be seen from orbit.

A Japanese moon probe tipped over on touchdown last month, limiting its ability to complete the planned science agenda. Altemus and Tim Crain, Intuitive’s chief technology officer, both were optimistic Odysseus can still accomplish most of its objectives.

But at least one hoped-for objective will not be met.

An experimental camera system built by students at Embry Riddle Aeronautical University, designed to be released before touchdown to capture imagery of the lander during its final descent, was not deployed as planned because of software constraints related to the guidance system problem.

The “EagleCam” package will be ejected later, Altemus said, shot out dozens of feet to one side. If all goes well, the cameras will show Odysseus resting on its side, giving engineers – and the public – the best views available of the spacecraft’s orientation.

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.”
