The Nicaragua Crater: The Result of a Meteorite Impact or Not?

By now, you’ve seen a pictures.

As astronomers tracked a tighten pass of Near Earth Asteroid 2014 RC this weekend, reports came out of Nicaragua that a probable meteorite struck circuitously a collateral of Managua.

Details are still sketchy, nonetheless supervision sources bring reports of a shrill crash and belligerent shock late Saturday night on Sep 6thLater images present late Sunday dusk showed a void 12 metres far-reaching and 5.5 metres low on a remote territory of a ubiquitous airfield during Managua, that also hosts a internal atmosphere force installation.

Reports state that a impact went off “like a bomb,” and Wilfried Strauch of a Nicaragua Institute of Earth Studies has already left on record as being “convinced it was a meteorite.” Investigators are now scouring a purported impact site for debris.

This has also sparked a sharp-witted contention opposite forums and amicable media: is a void a outcome of an supernatural impactor?

Of course, vast coincidences can and do happen. Last year, a tighten thoroughfare of asteroid 2012 DA14 was upstaged by a blast of a 20-metre asteroid over a city of Chelyabinsk on a really same day. And nonetheless a dual were conclusively proven to be unrelated, they did offer to lift ubiquitous tellurian recognition that, yes, vast melancholy rocks do indeed threat a Earth. And ironically, a aforementionedasteroid 2014 RC was about a same distance as a Chelyabinsk asteroid, that snuck adult on a Earth undetected from a sunward direction.

But Ron Baalke, a program operative during a Jet Propulsion Laboratory has posted an refurbish to a tighten pass by asteroid 2014 RC on the NASA’s Near Earth Object website, saying, “Since a blast in Nicaragua occurred a full 13 hours before a tighten thoroughfare of asteroid 2014 RC, these dual events are unrelated.”

Baalke also remarkable that “no watcher accounts or imagery have come to light of a fireball peep or waste route that is typically compared with a meteor of a distance compulsory to furnish such a crater.”

There are a few other problems with a Managua crater, nonetheless of course, we’d adore to be proven wrong. Many observers have remarkable that a void does not seem to demeanour fresh, and a trees and dirt around it seem to be comparatively undisturbed. A initial visible sense of a site looks some-more like a belligerent unemployment or sinkhole than an impact, or maybe an excavation. Others have also remarkable a likeness of a void with a troops blast, a really good probability with an atmosphere force bottom nearby.

Meteorite Men’s own Geoff Notkin has uttered doubts as to a flawlessness of a meteor void on Twitter.

Of course, it’s probable (though unlikely) that a impactor struck a site from true overhead, withdrawal a area around it undisturbed. As with meteor showers, an impactor distinguished a Earth before internal midnight would be entrance during a world frombehind at a reduce total velocity.

Color me doubtful on this one. Still, we’ve been wrong before, and it’s always a bonus for scholarship when a new meteorite tumble turns out to be real. Many have already cited a similarities between a Managua void and the Carancas eventuality in 2007 in Peru circuitously Lake Titicaca that was primarily deliberate indeterminate as well.

But again, it’s rarely extraordinary that a Managua eventuality is compared to 2014 RC, however, that done a closest pass over a southern hemisphere circuitously New Zealand many hours after during 18:18 UT on Sept 7th. We ran a new make-believe of a pass in Starry Night from a vantage indicate of a asteroid, and you’ll note that Central America is good out of view:

It’s also extraordinary that no still images or video of a Managua eventuality have nonetheless to surface. This is strange, as it occurred on a Saturday night near a collateral city of 2.4 million. Theweather over Managua was partly pale that night, and generally, a confidence camera or dual customarily catches steer of a fireball.

We also did a check by any arriving space junk reentries, that also valid to be a bad fit for a intensity suspect. The subsequent slated reentry is a BREEZE-M Tankwith a NORAD ID of 2011-074D compared with a 2011 launch of AMOS-5. This intent was not beyond around a time of a Managua event, and is likely to reenter on Sep 9th at 15:15 UT +/- 14 hours.

And a same goes for a launch of AsiaSat-6 by SpaceX on Saturday night, as launches from a Cape conduct out east opposite a Atlantic and divided from a Gulf of Mexico region.

Unfortunately, images and video would go a prolonged approach towards gauging a instruction and final circuit of a consider meteorite. The find of meteoritic waste during a site would also offer to bind a couple between a void and a vast impactor as well. Or perhaps, news of a imminent thoroughfare of NEO asteroid 2014 RC and a new pass of 2014 RA a weekend before had already primed a ubiquitous open to consider a meteor strike as an blast was listened late in a evening… we’ve lived circuitously bombing ranges, and are informed with a sound of late night explosions ourselves.

To be sure, a star is a dangerous place, and erring rocks from above do on arise have it out for any thoughtless class that gets in their way.

So we’ll open it adult for discussion: what do we consider happened on Saturday night circuitously Managua? Was it a meteorite, or another box of a “meteor-wrong?”
