SpaceX launches classified US spy satellite, sticks rocket landing to cap record year

Published

 on

CAPE CANAVERAL, Fla. — SpaceX launched a clandestine U.S. spy  satellite into space for the National Reconnaissance Office (NRO)  Saturday (Dec. 19) , marking its 26th rocket of the year.

The mysterious payload, called NROL-108, lifted off from Pad 39A here at NASA’s Kennedy Space Center at  9 a.m. (1400 GMT) , during a planned three hour launch window.

A used two-stage Falcon 9 rocket carried the spy satellite aloft, as part of a government mission called NROL-108, marking SpaceX’s 26th launch of 2020, a new record for the company. Approximately nine minutes after liftoff, the booster’s first stage produced some dramatic sonic booms as it made its way back to terra firma, touching down at SpaceX’s Landing Zone-1 (LZ-1) at the nearby Cape Canaveral Space Force Station.

Today’s flight was the fifth launch for this particular Falcon 9 first stage. The booster, designated B1059, previously lofted two commercial cargo missions to the International Space Station for NASA, delivered a batch of SpaceX Starlink satellites into orbit earlier this year, and most recently launched an Earth-observing satellite for Argentina.

Falcon 9 blasted off into a clear blue sky Saturday morning, a stark change from Thursday’s launch attempt. Thick clouds shrouded the rocket from view that day and ultimately an issue with the rocket’s second stage forced SpaceX to postpone the launch.

Several minutes after Falcon 9 leapt off the pad, the rocket’s first stage reappeared in the sky, with the iconic sonic booms you expect cracking overhead as the booster descended to the landing site.

B1059 is only the second booster to land on the ground at the Cape (as opposed to a drone ship at sea) this year. (A third landed on land at Vandenberg Air Force base in California following the launch of the Sentinel-6 Earth-observing satellite for NASA in November.) In fact, it’s now the third trip to LZ-1 for this booster, as the veteran Falcon 9 first stage also returned to land after delivering the CRS-20 mission into orbit earlier this year.

 A mystery payload

Today’s Falcon 9 launch carried a classified payload into orbit for the National Reconnaissance Office (NRO), the government agency that oversees the country’s fleet of spy satellites. Not much is known about the satellite except for the fact that the NRO secured the ride for the top secret cargo through non-traditional means.

Typically, the reconnaissance agency will secure its rides to space via the U.S. Space Force’s National Security Space Launch Program, but this time went about it on its own, according to a report from Spaceflight Now.

“In some cases, the NRO uses alternative methods to procure launch services after making a cumulative assessment of satellite risk tolerance, needed launch dates, available launch capabilities, and cost — all with a purpose of ensuring satellites are safely and securely delivered to orbit in a timely manner,” the spokesperson told Spaceflight Now.

Another interesting twist is that SpaceX did not conduct a static fire test of its rocket before flight. Typically, the company holds the rocket down on the pad and briefly fires its nine first-stage engines to make sure their systems are working as expected prior to liftoff. It’s rare that SpaceX skips this routine test but is not unheard of.

The mission marks the sixth launch of the year for the NRO, and will be the second overall to fly aboard a SpaceX Falcon 9. The first was the NROL-76 mission back in May 2017.

Falcon’s flight

The NROL-108 mission is SpaceX’s 50th reflight of a Falcon 9 since the company recovered its first booster in 2015. It also marks the 70th landing of a Falcon 9. To stick the landing, the booster separated from its upper stage and conducted a series of orbital ballet moves, reorienting itself for landing. Then it conducted a series of three engine burns to slow itself enough to gently touch down on its designated landing pad, marking the 21st successful land landing for SpaceX.

To facilitate reuse, the company normally relies on its two massive drone ships, named “Of Course I Still Love You” and “Just Read the Instructions,” the floating platforms are typically stationed out in the Atlantic Ocean and have enabled SpaceX to launch and subsequently land more rockets.

“Of Course I Still Love You” is sidelined for this mission, since the booster is returning to land, while “Just Read the Instructions” is currently bringing back a booster from the company’s most recent launch on Dce. 13. For that mission, a Falcon 9 rocket launched for the seventh time, carrying a massive satellite into space for SIrius XM. That booster is one of two that have flown that seven missions and should be sailing back into port around the same time as today’s launch.

Once they return to Florida’s Port Canaveral, the landed boosters are transported back to SpaceX facilities, where they’re carefully inspected and repurposed to fly again.

The current iteration of the Falcon 9 was finalized in 2018. Known as the Block 5, it features 1.7 million pounds of thrust as well as some other upgrades that make it capable of rapid reuse. SpaceX says that each of these boosters can fly as many as 10 times with minor refurbishments in between, and potentially as many as 100 times before retirement.

To date, SpaceX has launched and landed the same booster a maximum of seven times. According to company founder and CEO, Elon Musk, each Falcon 9 booster is capable of flying at least 10 times with minimal refurbishments in between flights. We have yet to see one fly that many times, but could see it next year.

Rocket fairing recovery

Ahead of today’s launch, SpaceX deployed one of its twin fairing catchers, GO Ms. Tree, to fetch the fairing pieces after today’s launch. GO Miss Chief, the company’s other fairing recovery vessel, stayed in port for the second mission in a row. These two boats act as giant, mobile catcher’s mitts, snagging payload fairings — the protective nose cones that surrounds satellites during launch — in their attached nets as they fall back down to Earth.

To that end, SpaceX has installed parachutes and special software in its payload fairings, which consist of two joined pieces. The fairings are designed to guide themselves to the recovery zone where Ms. Tree and Ms. Chief can wait to snag them as they fall back to Earth. If the boats miss or the weather is too poor to attempt a catch, the duo has on board equipment to scoop the fairing pieces up out of the water and carry them back to port for refurbishment.

The company has been successfully reusing the payload fairings, and the last mission — which launched the Sirius XM-7 satellite — was the first flight to feature a refurbished fairing on a non-SpaceX payload. Typically the company has been reusing fairings on its own Starlink missions. One of the fairing pieces that shrouded the Sirius XM-7 payload as it traveled through the atmosphere previously flew on the Anasis-II mission earlier this summer, which launched a communications satellite for South Korea’s military.

Today’s mission will mark the end of a busy launch year for the Cape. In total 31 missions have launched from the area this year, and 26 of those have been on SpaceX rockets. Next year, SpaceX is expected to continue to fill in its fleet of Starlink satellites, launch two more astronaut missions, and one of its heavy-lifters, the Falcon Heavy.

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.”
