SpaceX looks to launch space tourists to record heights – Teslarati

Published

 on



SpaceX has signed an agreement with a space tourism company that could see its Crew Dragon spacecraft take space tourists to heights unmatched by astronauts in half a century.

On Tuesday, February 18th, Space Adventures announced the agreement, revealing that it is now officially looking for wealthy private customers interested in launching to orbit on a SpaceX rocket and spacecraft. Known as Crew Dragon, that spacecraft is perhaps just two or three months away from SpaceX’s inaugural astronaut launch, in which two NASA astronauts will be sent into orbit to rendezvous and dock with the International Space Station (ISS) before returning to Earth after several weeks or months in space.

Founded in 1998, while Space Adventures has a slightly checkered past and has been more or less inactive for more than a decade, the company did manage to arrange eight separate spaceflights for seven private customers between 2001 and 2009. All flights previously arranged were done so through Russian space agency Roscosmos with Soyuz rockets and spacecraft and involved approximately week-long visits to the International Space Station (ISS), where the private astronauts – all multimillionaires and billionaires – mainly observed routine ISS operations and assisted with science experiments. With SpaceX’s Falcon 9 and Crew Dragon, Space Adventures hopes to soon offer orbital tourists an option that keeps all operations in the United States.

As noted, it must be stated that the February 18th agreement doesn’t actually mean that private customers will definitively launch into orbit in SpaceX’s Crew Dragon spacecraft. Instead, it serves as a semi-contractual confirmation that the spaceflight company is officially willing and ready to support such a mission in the event that Space Adventures is able to secure enough customers to purchase the necessary launch services. While not out of the question, that will be no easy feat.

Thankfully, several aspects of this new agreement should work in SpaceX and Space Adventures’ favor. As a unique ‘free-flying’ mission, Crew Dragon and its space tourists would not actually rendezvous with the ISS – instead serving as its own miniature outpost in Low Earth Orbit (LEO) for several days. Relative to SA’s past tourist flights to the ISS, this will save a large portion of the time and cost associated with both training civilians for spaceflight and ISS operations and working with NASA and Roscosmos to arrange the complex mission.

Aside from simplifying the training and bureaucracy involved in orbital tourism, the fact that Space Adventures’ newest proposal will have no affiliation or involvement with NASA or Roscosmos also means that there’s nothing preventing SpaceX from using a flight-proven Falcon 9 booster and Crew Dragon capsule on its space tourist launch. By combining flight-proven hardware with a space station-free mission profile, SpaceX could theoretically cut the overall flight’s cost by tens or even hundreds of millions of dollars.

According to public analyses performed over the last few years by auditors and researchers, SpaceX Crew Dragon launches will likely cost NASA around $400 million each, while a comparable Boeing Starliner mission will cost the space agency at least $650 million. The SpaceX figure is, however, predicated upon the production of a brand new Falcon 9 rocket and Crew Dragon spacecraft for each launch and includes costs associated with any processing or operations involving NASA teams and facilities.

As noted above, the use of a thoroughly flight-proven Falcon 9 booster and Crew Dragon capsule could dramatically cut the cost of private astronaut launches relative to the NASA baseline. It’s conceivable that – having effectively amortized the cost of the spacecraft and booster with a NASA astronaut launch – such a private mission’s price could be little more than the cost of building a new Falcon upper stage and Crew Dragon trunk, as well as booster/capsule refurbishment and general operations. Conservatively, the ultimate price SpaceX offers or offered Space Adventures could thus be as low as $100-200 million per launch.

Space Adventures says it could support as many as four space tourists on one flight, translating to a cost of $25-50 million per person if all seats are filled. This would compare reasonably well with the $20-50 million it typically charged its seven orbital tourism customers. That is still a vast sum of money and cuts the pool of potential customers to perhaps a few tens of thousands of people worldwide. Nevertheless, Google co-founder Sergey Brin (and possibly others) is on a sort of waiting list (requiring a $5 million deposit) for future orbital Space Adventures flights, giving the company at least one strong prospective customer.

At that altitude, Crew Dragon passengers would be able to glimpse almost 12 times more of the Earth’s surface compared to astronauts on the ISS. In other words, the resulting ‘overview effect’ could be a full magnitude more impressive. (NASA)

Thanks to skipping a space station rendezvous, perhaps the single biggest selling point of the mission is that Falcon 9 and Crew Dragon could potentially send space tourists higher than ever before – to an altitude only certain NASA Apollo and Gemini astronauts can claim to have surpassed. Space Adventures specifically notes this on its website, stating that prospective space tourists could reach an altitude that only Gemini 11 astronauts have surpassed while remaining in Earth orbit.

Gemini 11 astronauts reached an of apogee around 850 miles (1350 km) while still in Earth orbit – a record that stands today. Neither Space Adventures or SpaceX have specifically stated how high an unmodified Falcon 9 and Crew Dragon to launch private astronauts, but the implication is that the view would be comparable to – or even better than – what the Gemini 11 crew saw back in 1966. Regardless, it’s safe to say that if SpaceX and Space Adventures’ new space tourism effort is greeted with healthy demand, we’ll be shortly entering a new era of private spaceflight. Crew Dragon’s first private astronaut mission is tentatively scheduled to launch as early as late-2021 or early-2022.

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.”
