    NASA to crash 13,500mph spacecraft into ASTEROID in mission to stop deadly strike on Earth
    NASA is planning to smash a spacecraft into an asteroid in the next phase of its planetary defence experiment.
    ....
    As usual, Daily Star is being a bit hyperbolic;
    ....
    The asteroid that NASA aims to hit is not actually a threat to Earth, but by smashing into it, the DART crew will be able to see if a similar deflection would work on future asteroids.

    In the test, a NASA craft will slam into its target – asteroid Didymos – to see whether it can successfully change the direction of the rock.

    Didymos is approximately 800m across and has a secondary orbiting body – known as a “moonlet” – that is 150m in size.

    Using state-of-the-art technology, the spaceship will smash into the smaller satellite at a distance of 11 million km from Earth.

    Mesmerizing video shows what would happen if an asteroid crashed into Earth's oceans
    ...
    In films like Armageddon, Hollywood has tried (and failed) to take on the question of what would happen if a comet or asteroid plunged into the oceans on Earth, but what has scientific research actually determined it may look like?

    America's National Center for Atmospheric Research (NCAR) has posted a new video illustrating what could happen if an asteroid crashed into one of our oceans, and it's fascinating.

    Based on data collected by Los Alamos National Laboratory scientists Galen R. Gisler and John M. Patchett, referred to as the Deep Water Impact Ensemble Data Set, these simulations show asteroids of various sizes entering the water from different angles. It's the scale and size of the aftermath that's the truly stunning part.

    International Asteroid Day: Are we ready if an asteroid strikes Earth?
    ...
    Saturday is International Asteroid Day, commemorating the Earth's largest recorded asteroid impact while focusing on the real danger of asteroids that could collide with Earth.

    In 1908, a powerful asteroid struck the Podkamennaya Tunguska River in a remote Siberian forest of Russia. The event leveled trees and destroyed forests across 770 square miles which is equal to the size of three quarters of the US state of Rhode Island. The impact threw people to the ground in a town 40 miles away.

    Five years ago, an asteroid entered Earth's atmosphere over Chelyabinsk, Russia. It exploded in the air, releasing 20 to 30 times more energy than that of the first atomic bombs, generating brightness greater than the sun, exuding heat, damaging more than 7,000 buildings and injuring more than 1,000 people.

    Huge fireball lights up Russian skies
    ...
    More than five years after a large space rock slammed into the atmosphere over Russia, shattering thousands of windows in the city of Chelyabinsk below, another meteor exploded in the sky over the country last week, lighting up the early morning sky.

    The fireball was captured on camera near the town of Lipetsk, between Moscow and the Ukrainian border. It glows bright for a second, leaving a trail of smoke that lingers for several minutes afterwards.

    The impact of the meteor with Earth's atmosphere was picked up by US government sensors used to detect nuclear explosions, among other things. NASA estimates the resulting explosion packed a punch of about 2.8 kilotons, which pales compared with the 440 kiloton blast over Chelyabinsk in 2013, but is the most explosive asteroid entry measured so far in 2018.

    How Trump's Space Force Would Help Protect Earth from Future Asteroid Threats
    ...
    If a military Space Force like the one proposed by President Donald Trump becomes a reality, odds are, it would play a role in defending Earth from an incoming asteroid.

    In a report released today (June 20), NASA and other federal officials unveiled what the United States should do over the next 10 years to safeguard Earth from potential asteroid impacts. That 18-page plan, called the "The National Near-Earth Object Preparedness Strategy and Action Plan," would involve work from agencies across the federal government, White House officials said — even, potentially, Trump's proposed Space Force.

    "One of the things that should be clear from the report is that the responsibility for responding, and preparing response, is spread and shared throughout the U.S. government," Aaron Miles, of the White House Office of Science and Technology Policy, said in response to a question about a Space Force's role. "So everybody brings capabilities to the table … One of the objectives of this plan is coordinating and leveraging those capabilities where they are across the government."

    This Is NASA's New Plan to Detect and Destroy Asteroids Before They Hit Earth

    EXCERPT:
    ...
    NASA has updated its plans to deflect potentially hazardous Earth-bound asteroids — and none of them involve Bruce Willis.

    The White House Office of Science and Technology Policy released a new report today (June 20) titled the "National Near-Earth Object Preparedness Strategy and Action Plan." The 18-page document outlines the steps that NASA and the Federal Emergency Management Agency (FEMA) will take over the next 10 years to both prevent dangerous asteroids from striking Earth and prepare the country for the potential consequences of such an event.

    Officials with NASA, FEMA and the White House discussed the new asteroid-mitigation strategies in a teleconference with the media today. "An asteroid impact is one of the possible scenarios that we must be prepared for," Leviticus Lewis, chief of FEMA's National Response Coordination Branch, told reporters during the teleconference, adding that a catastrophic asteroid strike is "a low-probability but high-consequence event" for which "some degree of preparedness is necessary."

    Asteroid the size of a football field makes 'surprise' flyby close to Earth
    ...
    An asteroid the size of a football field buzzed by Earth Sunday in one of the closest encounters the planet has seen in a while.

    At its closest point, the asteroid – called 2018 GE3 – was just 119,500 miles away from Earth's atmosphere, about half the distance between Earth and the moon, according to NASA's Center for Near Earth Object Studies (CNEOS). The estimated diameter of the space rock ranged from 131 to 328 feet, CNEOS reports.
    ...
    The 2018 GE3 asteroid was discovered just one day before it skimmed past Earth in what scientists are calling a "surprise" flyby.

    "2018 GE3 was discovered by the Catalina Sky Survey approaching Earth on April 14th. Hours later, amateur astronomer Michael Jäger of Weißenkirchen Austria video-recorded the space rock gliding through the southern constellation Serpens," Spaceweather.com reported.
    ...

    Though not large enough to cause E.L.E. (Extinction Level Event (Impact)), the size could do significant Regional damage were it to impact and barely time for a "heads-up", but little prep. Indicates such could also happen with no forewarning, just "out of the blue".

    The latest analysis suggests that it is tumbling in a random manner which is said to indicate a major collision with something in its past so even in the extremely unlikely event that it's an artificial body it's a derilict

    According to Mass the only weather event which may even be remotely related to the weird tree fall could be a frontal zone due to have hit the area later in the evening and even he is weary of that explanation.

    The case has proven to be so perplexing that the fastidious researcher even joked that "perhaps the Sasquatch or alien visitation explanations should be taken seriously!"

    With that in mind, it's probably only a matter of time before someone puts forward a meteor-related theory for the mini-Tunguska event.

    Giant 'Potentially Hazardous' Asteroid Will Whiz By Earth So Close We Can See Inside It
    ...
    On February 4, an asteroid called 2002 AJ129 is due to slip past Earth. It is between 1600 and 4000 feet across, according to NASA's Center for Near Earth Object Studies, but there's no chance it will make impact—NASA has calculated it will remain 2.6 million miles away.

    That still makes it what astronomers call a "potentially hazardous asteroid," thanks to its size being more than about 500 feet across and an orbital path that carries it within about 4,650,000 miles of Earth.

    Newly-discovered asteroid will give Earth a close shave today

    EXCERPTS:
    ...
    When it comes to near-earth objects that might pose a threat, NASA is very much on top of things. That said, the sheer vastness of the sky means that some things will inevitably be missed, as is the case with the just-discovered asteroid named 2017 YZ4. The speedy space rock is hurtling in Earth’s general direction, and will slip by our planet today at a distance that is closer than that of the moon, which is a very close shave.

    2017 VZ4 isn’t a particularly large object, only measuring between 23 and 49 feet, but its close approach is enough to give scientists plenty of reasons to keep an eye on it. Most objects that pass within such a distance are considered “potentially hazardous” based on their size and speed. This particular visitor will make its pass at around 10:56 am EST.
    ...
    “This is the first known asteroid to fly by Earth within one lunar distance since two such asteroids flew past us on November 21, and the 52nd this year,” a NASA representative explained to The Express. “As of December 24, there are 17,495 known Near-Earth Objects (NEOs) around our planet; 17,389 are asteroids.”

    When it makes its closest approach to Earth, 2017 YZ4 will be traveling at a speed of around 21,000 miles per hour. That’s pretty speedy, but the object’s modest size means that even if it were to collide with us it wouldn’t exactly be a “planet killer.” Still, an asteroid strike of that size on a heavily populated would most certainly be devastating.
    ...

    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    Also:
    Named 2017 YZ4, the asteroid was only spotted on Christmas Day, which means very little could have been done to protect Earth if it were to hit.

    The asteroid passed between the Earth and moon at a distance of just 139,433 miles (224,000 km) - close enough to be considered a 'near miss' by astronomers.

    The potentially hazardous asteroid, which is 22.6 to 49 feet in diameter (seven to 15 metres) skimmed past Earth at 4.56pm GMT (11.56 ET) this afternoon.
    Just did, and now gone away ...
