Today\u2019s meteor explosion over Chelyabinsk is a wake-up call that the Earth orbits the Sun in a shooting gallery of asteroids, and that these asteroids sometimes hit the Earth. Later today, a separate and larger asteroid, 2012 DA14, narrowly missed the Earth passing beneath the orbits of our communications satellites. We have the technology to deflect asteroids, but we cannot do anything about the objects we don\u2019t know exist.<\/p>\n<p>To date, less than 1% of asteroids larger than the one that leveled Tunguska in 1908 have been tracked. The B612 Foundation Sentinel Space Telescope, to be launched in 2018, will provide a comprehensive map of the locations and trajectories of threatening asteroids and will give humanity the decades of warning needed to prevent asteroid impacts with existing technology. By the end of its planned lifetime, Sentinel will have discovered well over 90% of the asteroids that could destroy entire regions of Earth on impact (those larger than 350ft in diameter) and more than 50% of the currently unknown DA14-like near-Earth asteroids.<\/p>\n<p><a href=\"http:\/\/b612foundation.org\/ed-lus-message-our-cosmic-challenge\/\" target=\"_blank\" data-cke-saved-href=\"http:\/\/b612foundation.org\/ed-lus-message-our-cosmic-challenge\/\"><em>Continue&#8230;<\/em><\/a><\/p><\/blockquote>\n<p>* <strong><a href=\"http:\/\/www.planetaryresources.com\/2013\/02\/russian-meteorite-update\/\" target=\"_d\" data-cke-saved-href=\"http:\/\/www.planetaryresources.com\/2013\/02\/russian-meteorite-update\/\">Russian meteorite update &#8211; Planetary Resources<\/a><\/strong><\/p>\n<blockquote><p><a href=\"http:\/\/www.planetaryresources.com\/2013\/02\/planetary-resources-arkyd-100-spacecraft-to-assist-in-early-detection-and-characterization-of-near-earth-asteroids\/\" data-cke-saved-href=\"http:\/\/www.planetaryresources.com\/2013\/02\/planetary-resources-arkyd-100-spacecraft-to-assist-in-early-detection-and-characterization-of-near-earth-asteroids\/\">In our previous update<\/a>, we mentioned that many asteroids pass by Earth with little or no warning. <strong>We were not exaggerating<\/strong>. \u00a0Despite considerable progress in asteroid detection, only about one in ten close-approaching asteroids are known about ahead of time.
