  Most plane crashes are ‘survivable’
  [url=https://kra26c.cc]kraken сайт[/url]
  First, the good news. “The vast majority of aircraft accidents are survivable, and the majority of people in accidents survive,” says Galea. Since 1988, aircraft — and the seats inside them — must be built to withstand an impact of up to 16G, or g-force up to 16 times the force of gravity. That means, he says, that in most incidents, “it’s possible to survive the trauma of the impact of the crash.”
  
  For instance, he classes the initial Jeju Air incident as survivable — an assumed bird strike, engine loss and belly landing on the runway, without functioning landing gear. “Had it not smashed into the concrete reinforced obstacle at the end of the runway, it’s quite possible the majority, if not everyone, could have survived,” he says.
  
  The Azerbaijan Airlines crash, on the other hand, he classes as a non-survivable accident, and calls it a “miracle” that anyone made it out alive.

  Most aircraft involved in accidents, however, are not — as suspicion is growing over the Azerbaijan crash — shot out of the sky.
  
  And with modern planes built to withstand impacts and slow the spread of fire, Galea puts the chances of surviving a “survivable” accident at at least 90%.
  
  Instead, he says, what makes the difference between life and death in most modern accidents is how fast passengers can evacuate.
  
  Aircraft today must show that they can be evacuated in 90 seconds in order to gain certification. But a theoretical evacuation — practiced with volunteers at the manufacturers’ premises — is very different from the reality of a panicked public onboard a jet that has just crash-landed.
  Galea, an evacuation expert, has conducted research for the UK’s Civil Aviation Authority (CAA) looking at the most “survivable” seats on a plane. His landmark research, conducted over several years in the early 2000s, looked at how passengers and crew behaved during a post-crash evacuation, rather than looking at the crashes themselves. By compiling data from 1,917 passengers and 155 crew involved in 105 accidents from 1977 to 1999, his team created a database of human behavior around plane crashes.
  
  His analysis of which exits passengers actually used “shattered many myths about aircraft evacuation,” he says. “Prior to my study, it was believed that passengers tend to use their boarding exit because it was the most familiar, and that passengers tend to go forward. My analysis of the data demonstrated that none of these myths were supported by the evidence.”

  The survivors of recent crashes were sitting at the back of the plane. What does that tell us about airplane safety?
  [url=https://kra26c.cc]kraken зайти[/url]
  
  Look at the photos of the two fatal air crashes of the last two weeks, and amid the horror and the anguish, one thought might come to mind for frequent flyers.
  
  The old frequent-flyer adage is that sitting at the back of the plane is a safer place to be than at the front — and the wreckage of both Azerbaijan Airlines flight 8243 and Jeju Air flight 2216 seem to bear that out.
  https://kra26c.cc

  The 29 survivors of the Azeri crash were all sitting at the back of the plane, which split into two, leaving the rear half largely intact. The sole survivors of the South Korean crash, meanwhile, were the two flight attendants in their jumpseats in the very tail of the plane.
  
  So is that old adage — and the dark humor jokes about first and business class seats being good until there’s a problem with the plane — right after all?
  
  In 2015, TIME Magazine reporters wrote that they had combed through the records of all US plane crashes with both fatalities and survivors from 1985 to 2000, and found in a meta-analysis that seats in the back third of the aircraft had a 32% fatality rate overall, compared with 38% in the front third and 39% in the middle third.
  
  Even better, they found, were middle seats in that back third of the cabin, with a 28% fatality rate. The “worst” seats were aisles in the middle third of the aircraft, with a 44% fatality rate.
  But does that still hold true in 2024?
  
  According to aviation safety experts, it’s an old wives’ tale.
  
  “There isn’t any data that shows a correlation of seating to survivability,” says Hassan Shahidi, president of the Flight Safety Foundation. “Every accident is different.”
  
  “If we’re talking about a fatal crash, then there is almost no difference where one sits,” says Cheng-Lung Wu, associate professor at the School of Aviation of the University of New South Wales, Sydney.
  
  Ed Galea, professor of fire safety engineering at London’s University of Greenwich, who has conducted landmark studies on plane crash evacuations, warns, “There is no magic safest seat.”

  New Glenn’s first flight
  Blue Origin formally announced the development of New Glenn — which aims to outpower SpaceX’s Falcon 9 rockets and haul spacecraft up to 45 metric tons (99,200 pounds) to orbit — in 2016.
  [url=https://kra26att.cc]Кракен даркнет[/url]
  The vehicle is long overdue, as the company previously targeted 2020 for its first launch.
  
  Delays, however, are common in the aerospace industry. And the debut flight of a new vehicle is almost always significantly behind schedule.
  
  Rocket companies also typically take a conservative approach to the first liftoff, launching dummy payloads such as hunks of metal or, as was the case with SpaceX’s Falcon Heavy debut in 2018, an old cherry red sports car.

  Blue Origin has also branded itself as a company that aims to take a slow, diligent approach to rocket development that doesn’t “cut any corners,” according to Bezos, who founded Blue Origin and funds the company.
  
  The company’s mascot is a tortoise, paying homage to “The Tortoise and the Hare” fable that made the “slow and steady wins the race” mantra a childhood staple.
  
  “We believe slow is smooth and smooth is fast,” Bezos said in 2016. Those comments could be seen as an attempt to position Blue Origin as the anti-SpaceX, which is known to embrace speed and trial-and-error over slow, meticulous development processes.
  But SpaceX has certainly won the race to orbit. The company’s first orbital rocket, the Falcon 1, made a successful launch in September 2008. The company has deployed hundreds of missions to orbit since then.
  
  And while SpaceX routinely destroys rockets during test flights as it begins developing a new rocket, the company has a solid track record for operational missions. SpaceX’s Falcon 9 rocket, for example, has experienced two in-flight failures and one launchpad explosion but no catastrophic events during human missions.

  Scientists have identified an estimated 10% of all species on Earth. Here’s what they found in 2024
  [url=https://kra26c.cc]Љракен тор[/url]
  
  A toothy toadstool. A vegetarian piranha with a distinctive mark. And a pygmy pipehorse floating in the Indian Ocean shallows.
  
  These wild wonders were among the hundreds of previously unknown species of animals, plants and fungi that scientists named and described for the first time in 2024, expanding our surprisingly limited knowledge of Earth’s diversity.
  
  “Scientists estimate that we’ve identified only one-tenth of all species on Earth,” said Dr.
  Shannon Bennett, chief of science at the California Academy of Sciences, in a statement.
  
  https://kra26c.cc

  “While it is critical to place protections on known threatened species, we must also allocate resources towards identifying unknown species that may be just as important to the functioning of an ecosystem,” Bennett said.
  
  Researchers connected to the institution described 138 new species in 2024, including 32 fish. One standout was a pygmy pipehorse named Cylix nkosi. The seahorse relative was originally found in 2021 in the cool temperate waters surrounding the North Island of New Zealand, but the species described this year was discovered in the subtropical waters off South Africa, expanding the known range of this group to the Indian Ocean
  
  “South African reefs present notoriously difficult diving conditions with rough weather and intense, choppy waves — we knew we only had one dive to find it,” underwater photographer and marine biologist Richard Smith said in a statement.
  “This species is also quite cryptic, about the size of a golf tee, but luckily we spotted a female camouflaged against some sponges about a mile offshore on the sandy ocean floor.”
  
  The researchers involved in describing the new species chose nkosi as its name. A reference to the local Zulu word for “chief,” the name reflects the species’ crown-like head shape and acknowledges South Africa’s KwaZulu-Natal province where it was found.

  What’s on board this flight
  Blue Origin had planned to launch a pair of Mars-bound satellites on behalf of NASA for the first flight of New Glenn.
  
  But delays with the rocket’s development prompted the space agency to change course, moving that flight to this spring at the earliest. So for this inaugural flight, Blue Origin opted to instead fly a “demonstrator” that will test technology needed for the company’s proposed Blue Ring spacecraft — which will aim to serve as a sort of in-space rideshare vehicle, dragging satellites deeper into space when needed.
  [url=https://omgprice10.com]omg официальный сайт[/url]
  The demonstrator on this New Glenn flight will remain aboard the rocket for the entire six-hour flight, Blue Origin said, and it will validate “communications capabilities from orbit to ground” as well as “test its in-space telemetry, tracking and command hardware, and ground-based radiometric tracking.”
  
  The Blue Ring Pathfinder demonstrator is part of a deal Blue Origin inked with the US Department of Defense’s Defense Innovation Unit.

  Why Blue Origin wants to reuse rockets
  Similar to SpaceX, Blue Origin is aiming to recover and refly its first-stage rocket boosters in a bid to make launches less expensive.
  
  “Reusability is integral to radically reducing cost-per-launch,” the company said in a recent news release, using the same oft-repeated sentiment that SpaceX has touted since it began landing rocket boosters in 2015.
  Bezos, however, has acknowledged the importance of reusing rocket parts since he founded the company in 2000 — two years before Musk established SpaceX. And the company has already developed its suborbital New Shepard tourism rocket to be reusable.
  “It’s not a copy cat game,” Henry said. “Blue Origin has been pursuing reusable vehicles since before reusable vehicles were cool. Now it’s much more of a mainstream idea (because of SpaceX). The difference is that it’s taken Blue Origin so much longer to get to orbit.”
  
  If successful, returning the New Glenn rocket booster for a safe landing will be a stunning feat. After expending most of its fuel to propel the rocket’s upper stage to space, the first-stage booster will need to make a clean separation. The booster must then maneuver with pinpoint guidance and reignite its engines with precision timing to avoid crashing into the ocean or the Jacklyn recovery platform.

  On a long-dormant pad in Florida, a rocket that could challenge SpaceX’s dominance is poised to launch
  [url=https://kra26s.cc]kraken тор[/url]
  
  On a Florida launchpad that has been dormant for almost two decades, a new, roughly 320-foot (98-meter) rocket — developed by Jeff Bezos’ company Blue Origin — is poised for its maiden flight.
  
  The uncrewed launch vehicle, called New Glenn, will mark Blue Origin’s first attempt to send a rocket to orbit, a feat necessary if the company hopes to chip away at SpaceX’s long-held dominance in the industry.
  
  New Glenn is set to lift off from Cape Canaveral Space Force Station as early as next week.

  The rocket, which stands about as tall as a 30-story building, consists of several parts: The first-stage rocket booster gives the initial thrust at liftoff. Atop the booster is an upper rocket stage that includes a cargo bay protected by a nose cone that will house experimental technology for this mission.
  
  And, in an attempt to replicate the success that SpaceX has found reusing rocket boosters over the past decade, Blue Origin will also aim to guide New Glenn’s first-stage rocket booster back to a safe landing on a seafaring platform — named Jacklyn for Bezos’ mother — minutes after takeoff.
  
  Like SpaceX, Blue Origin will seek to recover, refurbish and reuse first-stage rocket boosters to drive down costs.
  
  For this inaugural mission, a smooth flight is not guaranteed.
  
  But the eventual success of New Glenn, named after storied NASA astronaut John Glenn, is instrumental to some of Blue Origin’s most ambitious goals.
  
  The rocket could one day power national security launches, haul Amazon internet satellites to space and even help in the construction of a space station that Blue Origin is developing with commercial partners.

  Chile’s President Boric leads journey to South Pole in historic trip
  [url=https://kra26s.cc]kraken войти[/url]
  
  Chile’s President Gabriel Boric travelled to Antarctica’s South Pole on Friday, a place where no other Latin American president has set foot, according to the Chilean government.
  
  Boric led the historic two-day trip, named Operation Pole Star III, to extend the environmental monitoring of pollutants on Antarctica, Chile’s government said in a statement.
  
  He travelled with scientists, armed forces commanders and government ministers from the Chilean capital of Santiago to Punta Arenas, a city in southern Chile, public broadcaster Television Nacional de Chile (TVN) reported. From there, they made several stops before finally reaching the US-run Amundsen-Scott South Pole Station, according to TVN.

  Chile is one of seven countries that has a territorial claim in Antarctica, alongside Argentina, Australia, France, New Zealand, Norway and the United Kingdom.
  
  It is also a signatory of the Antarctic Treaty, which dictates that the continent may only be used for peaceful and scientific purposes.
  
  While Chile has historically carried out scientific activity in Antarctica’s northern sector, the country’s government is now hoping to expand research into the west of the continent, its statement said.
  Boric called his trip to the South Pole an “honor” and a source of pride, TVN reported.
  
  “This is a milestone for us. It is the first time a Chilean and Latin American President has visited the South Pole,” he said, according to TVN.
