Space news weekly recap: NASA CAPSTONE, Martian 'Enchanted Lake' and more – The Indian Express

Published

 on


On June 28, NASA successfully launched the CAPSTONE project, which is the first step forward towards paving the way for the Artemis missions that will put astronauts back on the moon after a gap of 50 years. But that is just one development that happened last week. Here, we have put together some of the most exciting space news that happened over the previous week for you in case you missed it.

NASA launched CAPSTONE to pave the way for the moon

A small spacecraft launched on June 28 from New Zealand as part of the CAPSTONE mission. It contained a CubeSat satellite about the size of a microwave. Its objective is to reduce the risk for future spacecraft by testing out innovative navigation technologies and a new halo-shaped orbit that could be used by a space station orbiting the moon in the future.

The mission carries a dedicated payload flight computer and radio that will perform calculations to determine whether the CubeSat is in its intended orbital path. It will NASA’s Lunar Reconnaissance Orbiter (LRO) as a reference point. The idea here is that it will communicate directly with LRO and use the data obtained from this crosslink to measure how far it is from LRO and how fast the distance between the two changes, helping it determine its position in space.

NASA will use this to evaluate CAPSTONE’s autonomous navigation software called Cislunar Autonomous Positioning System (CAPS). Once successfully tested, the software could potentially allow future spacecraft to determine their location without having to rely exclusively on Earth-based tracking.

The orbit that it is testing, called a near rectilinear halo orbit (NRHO), is very elongated and its location is at a precise balance point between the gravities of the Earth and the moon. This orbit could offer stability for long-term missions like Gateway, a planned space station that will orbit the moon, and will require minimal energy to maintain. Once deployed, Gateway will serve as an ideal staging position for missions to the Moon and beyond.

An unusual impact site on the Moon from an unknown rocket

NASA’s LRO had spotted an unusual “double crater” on the Moon: an 18-metre-diametre eastern crater superimposed on a 16-metre-diameter western crater. The unexpected double crater formation indicates that whatever rocket caused it had large masses at each end, which is unusual because spent rockets typically have the mass concentrated at the motor end with the rest of the rocket stage consisting of an empty fuel tank.

No other rocket impacts on the Moon have created double craters as far as NASA scientists know. The four craters created by the third stage of the Saturn rockets (from Apollo 13, 14, 15 and 17) were irregular in outline and were substantially larger, with most being larger than 35 metres in diameter.

Researchers at the University of Arizona’s Space Domain Awareness lab at the Lunar and Planetary Observatory believe that the double crater was caused by a Chinese booster from a rocket launch in 2014. But NASA still refers to the impact crater ass having been created by a “mystery rocket”.

Using Curiosity rover data to measure key life ingredient on Mars

Using data from NASA’s Curiosity rover, scientists are measuring the total organic carbon in Martian rocks for the first time ever. There is evidence that the red planet’s climate was similar to Earth’s billions of years ago; with a thicker atmosphere and liquid water that flowed into rivers and seas. If life ever existed on Mars, scientists believe that the sites of these ancient water bodies would be the best place to look for signs. Organic carbon is an important component of life molecules.

The Curiosity rover went to the Yellowknife Bay formation in the Gale crater on Mars, which is the site of an ancient lake on Mars, and drilled samples from 3.5-billion-year-old mudstone rocks there. Curiosity then delivered the sample to the Sample Analysis at Mars (SAM) instrument, in which an oven heated powdered rock to progressively higher temperatures. It used oxygen and heat to convert organic carbon to carbon dioxide.

After that, it measured the amount of carbon dioxide so that scientists could later use this data to measure the amount of organic carbon in the rock. This experiment was actually performed in 2014 but it took years of analysis for the scientists to understand the data and put the results in the context of the mission’s other discoveries in the Gale crater. The resource-intensive experiment was only performed once during the Curiosity rover’s 10 years on Mars. Also, the presence of organic carbon doesn’t necessarily point to extra-terrestrial life as there are many non-biological processes that can create it.

NASA wants public help in spotting Martian clouds

The space agency has organised a project called “Cloudspotting on Mars” that uses its citizen science platform Zooniverse. Scientists at NASA are inviting the public to identify clouds on the red planet as part of the project hoping that it will help solve a fundamental mystery about Mars’ atmosphere.

NASA’s Mars Reconnaissance Orbiter has been studying the red planet since 2006 and its Mars Climate Sounder instrument has studied the planet’s atmosphere in infrared light. Teams at NASA are turning to the public for marking “arches” in sixteen years of infrared data. Clouds appear as arches in the data and can reportedly be spotted by human eyes easier than algorithms. Of course, NASA plans to use the crowd-sourced project to train better algorithms that can do this job in the future.

‘Enchanted Lake’ on Mars could be the best spot to look for life on Mars

NASA had shared images of an “Enchanted Lake” on Mars, where scientists believe that the perseverance rover could find the first evidence of extraterrestrial life. The Enchanted Lake is a rocky outcrop where scientists believe water existed in the past. The image was captured by the rover’s Hazard Avoidance Cameras (Hazcams) on April 30 this year.

The image was taken near the base of the Jezero Crater’s delta and provided scientists with the first close-up of sedimentary rocks on Mars. These rocks are usually formed when fine particles carried by water or air are deposited in layers which turn into rocks over time. Scientists believe that water existed in the Enchanted Lake in the past and that there is a chance that it could have harboured life when it did.

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.”
