  1. 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]kraken at[/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.
    https://kra26att.cc

    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.

  2. On a long-dormant pad in Florida, a rocket that could challenge SpaceX’s dominance is poised to launch
    [url=https://kra26s.cc]kra28 cc[/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.

  3. Chile’s President Boric leads journey to South Pole in historic trip
    [url=https://kra26s.cc]kraken ссылка[/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.

  5. 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 онион[/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.

  6. 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]omgprice10 cc[/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.

  7. An executive order designed to speed up the rebuilding of lost homes in LA has been put in place by California Governor Gavin Newsom.

    The order suspends Ceqa review and the California Coastal Act, which work to minimise the environmental impact of proposed building projects, as well as suspending some permits in order to make rebuilding quicker and more affordable.

    There are also protections against price gouging on services related to the fires such as building materials and storage services.

    He says “one thing I won’t give in to is delay. Delay is denial for people.”

    https://kraken6gf6o4rxewycqwjgfchzgxyfeoj5xafqbfm4vgvyaig2vmxvyd.shop
    “The executive order I signed today will help cut permitting delays, an important first step in allowing our communities to recover faster and stronger.”

  8. 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]кракен вход[/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
    kraken вход
    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.”
