SpaceX delivers for Turkey in first launch of 2021 – Spaceflight Now

A SpaceX Falcon 9 rocket thundered into space from Cape Canaveral and deployed a Turkish communications satellite Thursday night, the first of more than 40 Falcon rocket missions scheduled this year from launch pads in Florida and California.

The rapid-fire cadence of launches in 2021, if achieved, would break SpaceX’s record of 26 Falcon 9 flights last year, and rival the pace of U.S. launches during the early decades of the Space Age.

The first launch out of the gate was a Falcon 9 mission to deliver the Turkish-owned, Airbus-built Turksat 5A communications satellite to orbit.

The Falcon 9 did just that Thursday night, after a delay of more than 45 minutes to assess the readiness of a downrange tracking station in Gabon. The launch eventually proceeded without the tracking antenna, and the Falcon 9 lit its nine Merlin 1D main engines to fire off pad 40 at Cape Canaveral Space Force Station at 9:15 p.m. EST Thursday (0215 GMT) Thursday.

After arcing due east from Cape Canaveral, the Falcon 9 shed its first stage booster about two-and-a-half minutes into the flight, before beginning its descent toward a SpaceX drone ship parked around 400 miles (650 kilometers) east of Cape Canaveral in the Atlantic Ocean.

While the first stage booster targeted a vertical landing on the floating drone ship, two SpaceX vessels were on station in downrange waters to retrieve the Falcon 9’s two-piece payload shroud.

The Falcon 9 booster nailed its landing on the “Just Read the Instructions” drone ship in the Atlantic about eight-and-a-half minutes after liftoff, completing the reusable rocket’s fourth trip to space and back. An update on the fairing recovery effort was not immediately available from SpaceX.

The Falcon 9’s single-use upper stage, meanwhile, performed two engine burns before releasing the Turksat 5A spacecraft into an elliptical “supersynchronous” transfer orbit about 33 minutes after liftoff.

U.S. military tracking data indicated the Falcon 9 rocket released Turksat 5A in an orbit ranging between 177 miles (286 kilometers) and 34,000 miles (55,000 kilometers) in altitude, with an inclination of 17.66 degrees.

Turkish officials confirmed Thursday night that ground teams received the first radio signals from the Turksat 5A after launch, allowing controllers to begin health verifications and post-launch checkouts.

Turksat 5A, with a launch weight of around 7,500 pounds (3,400 kilograms) will deploy its power-generating solar panels and extend articulating pods holding plasma thrusters, which will slowly circularize the satellite’s orbit at geostationary altitude more than 22,000 miles over the equator. At that altitude, Turksat 5A will orbit Earth at the same rate the planet rotates.

The orbit-raising phase of the mission will last about four months. The electric thrusters are more fuel efficient than conventional liquid-fueled rocket engines, but produce less thrust.

The more efficient electric thrusters will allow Turksat 5A to maintain its position in orbit for more than 30 years, double the life span of many large communications satellites, according to Airbus.

The satellite will enter service by mid-year along the equator at 31 degrees east longitude, where its 42 Ku-band transponders will reach Turksat customers across Turkey, the Middle East, Europe, large swaths of Africa, the Mediterranean, the Aegean Sea, and the Black Sea, the company says.

Turksat 5A will become the most powerful satellite in Turksat’s fleet, according to Hasan Huseyin Ertok, the company’s deputy general manager. It will also help secure Turkish frequency rights at the 31 degrees east slot, where a Turkish-owned satellite has not operated since 2010.

Turksat awarded Airbus and SpaceX contracts to build and launch the Turksat 5A and Turksat 5B satellites in November 2017, following a meeting between SpaceX founder and CEO Elon Musk with Turkish President Recep Tayyip Erdoğan.

The Turksat 5B satellite, which will host a Ka-band communications payload, is scheduled for launch from Cape Canaveral in the second half of this year.

“Our main focus is Turkey, so it’s centered on Turkey but the whole (of) Europe, the most part of North Africa, and we go all the way to Kazakhstan going to the east. and in the African region, we have most of sub-Saharan Africa and also South Africa,” Ertok said of Turksat 5A’s coverage area.

“We can provide satellite service to anyone in that coverage area,” he said. “It can be a data service, which means bringing data from one point to another, or it can be a TV broadcasting service.”

While Turksat sells services to commercial customers, a major client for the company is the Turkish government. Turksat satellites have supported a range of Turkish civil and military operations.

Ertok said Turksat 5A will provide a “better service with a better price for our customers, to our government.”

“So it’s going to be an important satellite for us, and for our future,” he said.

SpaceX, meanwhile, is gearing up for its next Falcon 9 launch scheduled in mid-January from Cape Canaveral. That mission, which SpaceX calls Transporter 1, will delivery numerous commercial and government small satellites to orbit on a rideshare launch.

Two more Falcon 9 launches with SpaceX’s own Starlink broadband satellites are scheduled later in January or early February.

Elon Musk, SpaceX’s founder and CEO, said in October that the company planned as many as 48 Falcon 9 and Falcon Heavy missions in 2021 from three separate pads at Cape Canaveral Space Force Station, NASA’s Kennedy Space Center, and Vandenberg Air Force Base, California.

SpaceX officials have set an ambition to launch batches of Starlink internet satellites as often as once every two weeks, when breaks between the company’s other missions allow managers to add a flight to the Falcon 9 manifest.

Besides Starlink missions, SpaceX has at least 20 Falcon 9 and Falcon Heavy flights this year for external customers.

Those include two Falcon 9 launches with Crew Dragon missions — flown under contract to NASA — to carry four astronauts to the International Space Station for six-month expeditions. There is also a shorter duration commercial Crew Dragon mission planned for launch in late 2021 with Axiom, a privately-held space company, to ferry four paying passengers to and from the space station.

SpaceX also plans to launch up to three automated Dragon resupply missions to the space station in 2021, and an asteroid probe and an X-ray space telescope for NASA.

There are also at least two flights by SpaceX’s triple-body Falcon Heavy rocket planned this year with U.S. military payloads.

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.”
