B.C. researchers find evidence of ancient predatory sand worms that were two metres long – National Post

The trace fossils showed feather-like structures around the upper parts of the burrows, which the researchers believe would have been caused by the worms dragging their struggling prey under the ocean floor to eat them.

The study’s lead author, earth sciences student Yu-Yen Pan, said the giant burrows are much larger than other trace fossils of ocean worms found in the past.

“Compared to other trace fossils which are usually only a few tens of centimetres long, this one was huge; two-metres long and two to three centimetres in diameter,” she said in a press release. “The distinctive, feather-like structures around the upper burrow were also unique and no previously studied trace fossil has shown similar features.”

The researchers say that these worms likely would have fed similarly to the bobbit worm, often called the “sand striker.”

The researchers also found evidence that led them to believe the worms secreted mucus after each feeding that rebuilt and reinforced their burrows, allowing them to lie in wait for their next victim without being seen.

Pan and an international team that studies the ancient sea floor has named the homes of these worms Pennichnus formosae.

According to the study, previous research on Eunicid polychaetes, the family that these ancient worms and bobbit worms belong to, was limited because they only stuck a small portion of their bodies out from the ocean floor.

These trace fossils have allowed researchers to better understand the activity and habits of the ancient species.

Predatory ocean worms have existed for over 400 million years, and while these ancient burrows are long when compared to others that had previously been studied, giant marine worms are not just creatures of the ancient past.

Bobbit worms can grow up to three metres long themselves, and lay in their burrows just beneath the ocean floor today.

Video "Perseverance" robot moves to the surface of Mars for the first time – SwordsToday.ie

Published

 on




The U.S. space agency “NASA” announced on Friday that the probe “Perseverance” had succeeded in traveling a few meters on Mars for the first time since it landed on the surface two weeks ago.

The six-wheeled mobile robot advanced four meters on Thursday afternoon, then turned itself to the left and then retracted about two and a half meters to check if its operating systems were working properly.

“Perseverance” was able to take pictures of its own wheels on the surface of Mars, published by NASA. The rover crossed six and a half meters in 33 minutes.

Search for clues to ancient life

“I don’t think I’ve ever been as happy as I used to be when I saw the wheel tracks,” said the engineer in charge of robot mobility at NASA’s Jet Propulsion Laboratory, which designed the vehicle. The engineer noted at a press conference that the first phase of the investigation had progressed very well, completing its mission “a very important step”.

The spacecraft can travel up to 200 meters on each Mars (slightly longer than Earth). It travels at five times the speed of any other Curiosity rover still operating on Mars.

Mobile Android “Preference” has landed The surface of Mars on February 18th The last thing on the Gizero crater that scientists believe to have been a deep lake about 3.5 billion years ago.


Thirty rock samples from the planet will be explored in two years, and another vehicle will return to Earth to find evidence of ancient life on the Red Planet.

Scientists are now observing two journeys of a mobile robot to the delta formed by an ancient river flowing into the lake, as researchers place great importance on exploring it as it is likely to contain large amounts of debris.

The first laser shot from “Supercam”

Before that, the helicopter will launch a small “ingenuity” under the vehicle, which will become the first motor vehicle to fly in the atmosphere of another planet. NASA teams are looking for the best place to conduct this historic experiment “before the end of spring,” Deputy Chief of Mission Robert Hogg promised Friday.

PrioritySo far, its cameras have captured more than 7,000 images on Earth. On February 24, NASA released a remarkable panoramic image that collected several shots taken at the landing site of the mobile robot, showing the top of the Jessero crater.

One of the photos of the vehicle shows a light brown rock. In its analysis, a scientific instrument called “Supercom” was used for the first time. NASA expects to present the results next week.

The U.S. space agency also named the landing site “Perseverance” after Octavia e-Butler, a science fiction writer born in Pasadena, California, where JPL is located.

NASA's Perseverance Mars rover digging in with BC-made part – Chilliwack Progress – Chilliwack Progress

Published

 on


Greater Victoria’s Kennametal Inc. facility is used to making custom products for industry spanning every corner of the globe.

However, it’s the piece the plant made for a jobsite that’s currently over 200 million kilometres away that’s bringing the company an out-of-this-world amount of pride.

The site made a tungsten carbide tooth blank that’s currently mounted to a core drill on NASA’s Perseverance rover, which landed on Mars last month. The blank is involved in one of the six-wheeled rover’s key tasks; cutting chalk-sized, intact rock cores that will hopefully be sent back to Earth and give a greater understanding into ancient microbial life on Mars.

“The team is just super enthusiastic and super excited,” said Ron Sivorot, business director at the Kennametal site in the Greater Victoria suburb of Langford. “Having it in use millions of miles away is actually pretty crazy.”

But even though they’re making a component used in space exploration, nothing really changed at the Langford site. Had nobody told the plant’s employees about the company’s involvement in the mission, they might’ve never known.

“The team on the shop floor didn’t even really know that there was anything going on, that it was anything different from anything else they make,” Sivorot said. “We make millions of pieces of carbide a year and to have these ones go to Mars, it’s obviously, definitely the farthest we’ve gone.”

Excitement started to grow in 2018 after Kennametal found out the blanks —which the Langford site has been supplying to NASA’s Jet Propulsion Laboratory since 2014 —would be aboard the interplanetary mission.

“It just kind of fit right into our work flow, so to be honest, we didn’t go above and beyond, this is basically the service we’re used to giving anyway, it just fit to serve NASA and JPL,” Sivorot said.

The Langford site employees watched from their work computers as the rover touched down on the red planet. Images of NASA’s control room engineers erupting with elation upon the six-wheeled rover’s interstellar landing matched the scene at the local Kennametal site. Sivorot said some of the plant’s space-loving employees were caught geeking out with celebratory air punches as they watched the landing back here on Earth.

The k92-grade tooth blank Kennametal makes for NASA looks like a small metal cube that’s smaller than a fingernail. To make the blank, Kennametal reforms powdered tungsten carbide by pressing, shaping and centring it and giving the piece a semi-finished grind. Once NASA gets the blank, they finish grinding the piece to their specific and high-tech requirements.

The k92-grade tooth blank is also used in industries like construction, oil and gas, agriculture and forestry. The Kennametal director said tungsten carbide is used because its strength and durability can perform in hostile scenarios.

“We have a variety of other customers that use it in similar applications, other than being on another planet,” Sivorot said. “We have a lot of confidence in this grade. It’s a very tough grade, fracture resistant, wear resistant, it’s an ideal grade for this solution, so we’re confident that it’ll do what it needs to do on Mars.”

NASA says Mars was 205 million kilometres form Earth when Perseverance landed, but the rover equipped with the Kennametal product travelled 471 million kilometres in total since last summer’s launch.

“Which is super wild,” Sivorot said, “it’s actually one of those fun stories you go home and tell your kids about.”
