Surprise: Earth Is Hit By a Lot More Asteroids Than You Thought

“The fact that none of these asteroid impacts shown in the video was detected in advance is proof that the only thing preventing a catastrophe from a ‘city-killer’ sized asteroid is blind luck.”

– Ed Lu, B612 Foundation CEO and former NASA astronaut

When we think of recent large asteroid impacts on Earth, only a handful may come to mind. In particular, one is the forest-flattening 1908 Tunguska explosion over Siberia (which may have been the result of a comet) and another is the February 2013 meteor that exploded over Chelyabinsk, shattering windows with its air blast. Both occurred in Russia, the largest country on Earth, and had human witnesses — in the case of the latter many witnesses thanks to today’s ubiquitous dashboard cameras.

While it’s true that those two observed events took place 105 years apart, there have been many, many more large-scale asteroid impacts around the world that people have not witnessed, if only due to their remote locations… impact events that, if they or ones like them ever occurred above a city or populated area, could result in destruction of property, injuries to people, or worse.

(And I’m only referring to the ones we’ve found out about over the past 13 years.)

A new video released by the B612 Foundation shows a visualization of data collected by a global nuclear weapons test network. It reveals 26 explosive events recorded from 2000 to 2013 that were not the result of nuclear detonations — these were impacts by asteroids, ranging from one to 600 kilotons in energy output.

Update: a list of the 26 aforementioned impacts and their energy outputs is below:

8/25/2000 (1-9 kilotons) North Pacific Ocean
4/23/2001 (1-9 kilotons) North Pacific Ocean
3/9/2002 (1-9 kilotons) North Pacific Ocean
6/6/2002 (20+ kilotons) Mediterranean Sea
11/10/2002 (1-9 kilotons) North Pacific Ocean
9/3/2004 (20+ kilotons) Southern Ocean
10/7/2004 (10-20 kilotons) Indian Ocean
10/26/2005 (1-9 kilotons) South Pacific Ocean
11/9/2005 (1-9 kilotons) New South Wales, Australia
2/6/2006 (1-9 kilotons) South Atlantic Ocean
5/21/2006 (1-9 kilotons) South Atlantic Ocean
8/9/2006 (1-9 kilotons) Indian Ocean
9/2/2006 (1-9 kilotons) Indian Ocean
10/2/2006 (1-9 kilotons) Arabian Sea
12/9/2006 (10-20 kilotons) Egypt
9/22/2007 (1-9 kilotons) Indian Ocean
12/26/2007 (1-9 kilotons) South Pacific Ocean
10/7/2008 (1-9 kilotons) Sudan
10/8/2009 (20+ kilotons) South Sulawesi, Indonesia
9/3/2010 (10-20 kilotons) South Pacific Ocean
12/25/2010 (1-9 kilotons) Tasman Sea
4/22/2012 (1-9 kilotons) California, USA
2/15/2013, (20+ kilotons) Chelyabinsk Oblast, Russia
4/21/2013 (1-9 kilotons) Santiago del Estero, Argentina
4/30/2013 (10-20 kilotons) North Atlantic Ocean

To include the traditonally macabre comparison, the bomb used to destroy Hiroshima at the end of World War II was about 15 kilotons; the Nagasaki bomb was 20.

This evening former NASA astronauts Ed Lu, Tom Jones, and Apollo 8 astronaut Bill Anders will present this video to the public at a live Q&A event at the Museum of Flight in Seattle, Washington.

CEO and co-founder of the B612 Foundation, Ed Lu is working to increase awareness of asteroids and near-Earth objects with the ultimate goal of building and launching Sentinel, an infrared observatory that will search for and identify as-yet unknown objects with orbits that intersect Earth’s. The event, titled “Saving the Earth by Keeping Big Asteroids Away,” will be held at 6 p.m. PDT. It is free to the public and the visualization above is now available online on the B612 Foundation website. A press event will also be taking place at 11:30 a.m. PDT, and will be streamed live here.

Currently there is no comprehensive dynamic map of our inner solar system showing the positions and trajectories of these asteroids that might threaten Earth. The citizens of Earth are essentially flying around the Solar System with eyes closed. Asteroids have struck Earth before, and they will again – unless we do something about it.

Technical note: While B612 and Ed Lu are presenting a new visualization on April 22, the data behind it are not entirely new. Previous surveys on NEA populations have determined within reasonable parameters the number of objects and likelihood of future impacts of varying sizes using data from WISE and ground-based observatories… see a series of slides by Alan Harris of JPL/Caltech here.

Astronauts to Reveal Sobering Data on Asteroid Impacts

This Earth Day, Tuesday, April 22, three former NASA astronauts will present new evidence that our planet has experienced many more large-scale asteroid impacts over the past decade than previously thought… three to ten times more, in fact. A new visualization of data from a nuclear weapons warning network, to be unveiled by B612 Foundation CEO Ed Lu during the evening event at Seattle’s Museum of Flight, shows that “the only thing preventing a catastrophe from a ‘city-killer’ sized asteroid is blind luck.”

Since 2001, 26 atomic-bomb-scale explosions have occurred in remote locations around the world, far from populated areas, made evident by a nuclear weapons test warning network. In a recent press release B612 Foundation CEO Ed Lu states:

“This network has detected 26 multi-kiloton explosions since 2001, all of which are due to asteroid impacts. It shows that asteroid impacts are NOT rare — but actually 3-10 times more common than we previously thought. The fact that none of these asteroid impacts shown in the video was detected in advance is proof that the only thing preventing a catastrophe from a ‘city-killer’ sized asteroid is blind luck. The goal of the B612 Sentinel mission is to find and track asteroids decades before they hit Earth, allowing us to easily deflect them.”

The B612 Foundation is partnered with Ball Aerospace to build the Sentinel Infrared Space Telescope Mission. Once positioned in solar orbit closer to the Sun from Earth, Sentinel will look outwards in infrared to detect hundreds of thousands of as-yet unknown near-Earth objects over 140 meters in size. The privately-funded spacecraft is slated to launch in 2017-18 aboard a SpaceX Falcon 9 rocket.

In addition to Lu, Space Shuttle astronaut Tom Jones and Apollo 8 astronaut Bill Anders will be speaking at the event, titled “Saving the Earth by Keeping Big Asteroids Away.”

The event will be held at 6 p.m. PDT at the Museum of Flight in Seattle, WA. It is free to the public and the visualization will be made available online on the B612 Foundation website.
