  1. On a long-dormant pad in Florida, a rocket that could challenge SpaceX’s dominance is poised to launch
    [url=https://kra23s.cc]кракен[/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.

  2. The most exciting new trains coming in 2025

    Amazing adventures, extraordinary landscapes and fabulous cuisine — the world’s greatest railway journeys are an unforgettable experience that can immerse you in the culture of a new country.

    Demand for luxury “land cruise” trains with five-star hotel-style accommodation is booming. 2025 will see several new trains take to the rails for the first time, offering new opportunities to explore Italy, France, Saudi Arabia and the United Kingdom.

    But the best railway journeys don’t have to be the most expensive. There’s an ever-evolving world of train trips out there. Here are some of the key developments in the coming year
    Two of Europe’s great capitals are now linked by their first direct high-speed train connection. Germany’s Deutsche Bahn introduced a daytime InterCity Express (ICE) service between Paris and Berlin on December 16 and is planning to add a second route between the two capitals in 2026.

    Taking advantage of its new fleet of 200 mph (322 kph) ICE3neo trains, the once-a-day service takes around eight hours in each direction, also serving Strasbourg, Karlsruhe and Frankfurt on its 546-mile (878-kilometer) journey.

    Fares start from around $60, and each train has capacity for 444 passengers, of which 111 can enjoy the additional comfort of leather seats and at-seat refreshments in first class.

    The new high-speed ICE service is the first direct daytime train between Paris and Berlin since the 1990s and complements the Nightjet sleeper service introduced in 2023.

    It may not be as fast as flying — some of the journey has to use lower speed “classic” lines to bridge gaps in the European high-speed network — but it is undoubtedly a more sustainable and more stylish way to travel across Europe.

  3. 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.

    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.

  4. What New Glenn will do
    In some ways, New Glenn has already made its mark on the launch industry. Blue Origin has for years pitched the rocket to compete with both SpaceX and United Launch Alliance — a joint venture of Boeing and Lockheed Martin that buys engines from Blue Origin — for lucrative military launch contracts.
    [url=https://omgprice10.com]omg зайти[/url]
    The US Space Force selected Blue Origin, ULA and SpaceX in June to compete for $5.6 billion worth of Pentagon contracts for national security missions slated to launch over the next four years.
    Blue Origin also has deals with several commercial companies to launch satellites. The contracts include plans to help deploy Amazon’s Kuiper internet satellites and a recently inked deal with AST SpaceMobile to help launch the Midland, Texas-based company’s space-based cellular broadband network.

    New Glenn could also be instrumental in building Blue Origin’s planned space station, called Orbital Reef. Blue Origin and it commercial partners, including Sierra Space and Boeing, among others, hope the station will one day provide a new destination for astronauts as the International Space Station is phased out of service.

    New Glenn vs. other powerful rockets
    New Glenn packs significant power. Dubbed a “heavy-lift” vehicle, its capabilities lie between SpaceX’s Falcon 9 rocket and the more powerful Falcon Heavy launch vehicle.

    SpaceX’s workhorse Falcon 9, for example, can haul up to 22.8 metric tons (50,265 pounds) to space. While New Glenn is capable of carrying about double that mass, it may also be roughly the same price as a Falcon 9: reportedly around $60 million to $70 million per launch.

    “I think in order to compete with Falcon 9, you have to go head-to-head or better on price,” said Caleb Henry, the director of research at Quilty Space, which provides data and analysis about the space sector.

    The question, however, is whether Blue Origin will be able to sustain a competitive price point, Henry added.

    Still, one feature that makes New Glenn stand out is its large payload fairing, or nose cone. The component protects the cargo bay and is a whopping 23 feet (7 meters) wide — nearly 6 feet (2 meters) larger than that of SpaceX’s Falcon 9 or Falcon Heavy.

    Henry said Blue Origin likely opted to outfit New Glenn with such a large fairing in order to help fulfill Bezos’ vision of the future.

  6. A year ago today, things went from bad to worse for Boeing
    [url=https://kra23c.cc]кракен даркнет[/url]

    At 5 p.m. PT on January 5, 2024, Boeing seemed like a company on the upswing. It didn’t last. Minutes later, a near-tragedy set off a full year of problems.

    As Alaska Airlines flight 1282 climbed to 16,000 feet in its departure from Portland, Oregon, a door plug blew out near the rear of the plane, leaving a gaping hole in the fuselage. Phones and clothing were ripped away from passengers and sent hurtling into the night sky. Oxygen masks dropped, and the rush of air twisted seats next to the hole toward the opening.

    Fortunately, those were among the few empty seats on the flight, and the crew got the plane on the ground without any serious injuries. The incident could have been far worse — even a fatal crash.

    Not much has gone right for Boeing ever since. The company has had one misstep after another, ranging from embarrassing to horrifying. And many of the problems are poised to extend into 2025 and perhaps beyond.

    The problems were capped by another Boeing crash in South Korea that killed 179 people on December 29 in what was in the year’s worst aviation disaster. The cause of the crash of a 15-year old Boeing jet flown by Korean discount carrier Jeju Air is still under investigation, and it is quite possible that Boeing will not be found liable for anything that led to the tragedy.
    But unlike the Jeju crash, most of the problems of the last 12 months have clearly been Boeing’s fault.

    And 2024 was the sixth straight year of serious problems for the once proud, now embattled company, starting with the 20-month grounding of its best selling plane, the 737 Max, following two fatal crashes in late 2018 and early 2019, which killed 346 people.

    Still the outlook for 2024 right before the Alaska Air incident had been somewhat promising. The company had just achieved the best sales month in its history in December 2023, capping its strongest sales year since 2018.

    It was believed to be on the verge of getting Federal Aviation Administration approval for two new models, the 737 Max 7 and Max 10, with airline customers eager to take delivery. Approvals and deliveries of its next generation widebody, the 777X, were believed to be close behind. Its production rate had been climbing and there were hopes that it could be on the verge of returning to profitability for the first time since 2018.

  7. The survivors of recent crashes were sitting at the back of the plane. What does that tell us about airplane safety?
    [url=https://kra23c.cc]кракен онион[/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://kra23c.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.”

  8. Scientists have identified an estimated 10% of all species on Earth. Here’s what they found in 2024
    [url=https://kra23c.cc]kraken официальный сайт[/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.

    “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.
