International space agencies team up to practice for an asteroid striking Earth

You've gotta hand it to America's space scientists: they're resilient. Despite an admission that they may not be able to stop the asteroid Bennu from turning Earth into a smoldering crater filled with the ashen remains of its human inhabitants, NASA's Planetary Defense Coordination Office (PDCO) has teamed up with FEMA and other agencies for what amounts to a wargaming exercise to prepare themselves for a catastrophic asteroid strike.

The best part of this? The ESA is tweeting out bits and pieces of the scenario - that an asteroid named 2019PDC has been spotted and calculated to have a 1 in 100 chance of striking Earth - as if it were happening in real time. The agency has wisely hashtagged the relevant tweets with #FICTIONALEVENT to avoid any War of the Worlds scenarios.

Meteor fireball explodes over Costa Rica, possibly crashes into home

A large meteor fireball exploded in the sky over Costa Rica on April 23, 2019 at 9:09pm.

People reported seeing flashes in the sky. Others reported hearing loud booms and feeling rumblings.

On the same evening a rock fell from the sky, making a hole in a roof in Aguas Zarcas, San Carlos, Alajuela. Now experts will analyse the rock to determine its origin. But I bet it is a meteorite!

The woman who found the space rock in her house explains she heard a loud rumble, went to the back of her house, discovered the hole in the roof and found the warm rock on the floor.

Now, cosmochemist (I am one of those :-)) will have to analyse the chemical composion of the rock to determine where this rock comes from... But it is ... the meteorite!


Comment: Just two weeks earlier, a bright meteor fireball was filmed streaking through Puerto Rico skies.

Northern Ireland meteorite crash remembered 50 years on

Terence Murtagh speaking to UTV about the meteorite 50 years on.
Some of those who witnessed the Bovedy meteorite which crashed in Northern Ireland 50 years ago have been remembering the event at the Armagh Planetarium.

The meteorite is named after the townland near Kilrea where it fell on 25 April 1969.

It had been seen passing over the South East of England and over Wales before it crashed - and was described as looking like a shooting star or fireball as it fragmented coming into land.

It was found three days later and had broken into two traceable pieces, one which had fallen through the roof of a shop in Lisburn and the other on a farm in Bovedy.

Former director of the planetarium Terence Murtagh is one of those who saw the shooting star and helped locate it after it fell to Earth.

While locals around Geelong and Wyndham have been enjoying their Easter break, some have experienced an extra special moment.

Following Good Friday's supermoon, a meteor was also seen darting across the sky on Easter Saturday.

The brief, but bright, event occurred around 6:53pm in the northern part of the Melbourne and Geelong sky.

So far, the newsroom can confirm it was seen in Glen Waverley and Werribee in Melbourne, as well as Mildura, Swan Hill and the Murray River.

'Loud bang' heard in Suffolk, England

A mystery bang left families in Claydon and Great Blakenham in shock last night - with some fearing it was the result of a crash on the A14 and others concerned there may have been an explosion.

But this morning, with those theories disproved, they have been left scratching their heads over what the loud bang could have been - and wondering if it could have been a sonic boom or even a 'skyquake'.

There have been further reports of another loud bang being heard in Martlesham and Kesgrave at around 8pm.

Harrison Cartwright, from Claydon, was at the doctors at 6.45pm when he heard the loud clash and then felt the room shake.

We checked with Elyria Fire who had no reports of any explosions.

Elyria Police did take a call.

"We received one call last night from a resident who lives in the southeast part of the city. We responded but were unable to determine what caused it," Elyria Police Chief Duane P. Whitely said. "We have no information on what caused the "boom.""

We also checked with Lorain County Dispatch and the only report of a loud noise they had last night was for loud music.

Very bright meteor fireball over Germany on April 16, 2019.
A bright green fireball was seen and recorded streaking through the night sky above northern Germany on April 16, 2019 around 21:51 UT.

The American Meteor Society (AMS) received more than 60 reports of event 1774-2019 from Germany, Sweden, Denmark and the Netherlands.

A video was uploaded to AMS showing the event together with 1775-2019, which shows another bright meteor fireball blaze over the US east coast. AMS has received 417 reports of this event on Wednesday, April 17th 2019 around 02:57 UT.

A meteor was seen along the U.S. East Coast on late Tuesday night
Hundreds of people in the Mid-Atlantic and New England reported they looked up on Tuesday night and saw a meteor hurtling through the skies.

The meteor soared over the D.C. area about 11 p.m., and the brilliant shine caught a lot of eyes.

Steve Chazin was driving from Virginia's Dulles Airport on Route 50 when his dashcam caught the sight: an illuminated orb flying through the skies, surrounded by a glow and backed by a tail.

The American Meteor Society had 325 reports of the celestial event pour in from Washington, D.C., and 11 states, including Maryland, Virginia and West Virginia.


Comment: Additional footage of the event:

A meteor fireball flies over the Mediterranean, falling off the Moroccan coast

On Sunday, a fireball was recorded by a Spanish platform that detects meteoroids. The rock was produced by a rock detached from an asteroid, a Spanish astrophysicist told Yabiladi.

On Sunday, April the 14th, a fireball was spotted near the Moroccan coast. The phenomenon was recorded in the framework of the SMART project (University of Huelva), created to detect meteoroids interacting with the Earth's atmosphere, Meteor News reported.

It was produced by a meteoroid from the Virginids that hit the atmosphere at about 65,000 km/h, the scientific platform added.

Speaking to Yabiladi on Tuesday, Spanish astrophysicist José María Madiedo who is part of the SMART project said that the fireball that flew over the Mediterranean «was produced by a rock detached from an asteroid.

SpaceX contracted by NASA to attempt to 'redirect' asteroid

Despite an admission last year that it may be impossible to stop the 8.8 ton asteroid
Bennu from annihilating life on Earth, the perennial optimists at NASA have nevertheless granted SpaceX a $69 million contract to assist in the Double Asteroid Redirection Test (DART), intended to save Earth from interstellar armageddon. The test, tentatively scheduled for June 2021, will have Elon's Musketeers crashing a kinetic impactor - in this case, a spacecraft equipped with cameras and solar panels - into a small moonlet accompanying Didymos, an 800-meter-long near-Earth asteroid. NASA notes that the moonlet, dubbed "Didymoon" by scientists, "is more typical of the size of asteroids that could pose a more common hazard to Earth" than its massive chaperone.

The goal, NASA says, is to launch the DART spacecraft atop a SpaceX Falcon 9 rocket that will then make its way to Didymos and Didymoon to attempt to alter the latter's trajectory in a rehearsal for what could one day be a high-stakes game of cosmic bumper cars. "By using solar electric propulsion," NASA says, "DART will intercept the asteroid Didymos' small moon in October 2022, when the asteroid will be within 11 million kilometers of Earth." Meanwhile, Earthlings will watch with bated breath.

"The collision will change the speed of the moonlet in its orbit around the main body by a fraction of one percent," NASA promises, "enough to be measured using telescopes on Earth."
