There are about 1 million near-Earth asteroids that are large enough to substantially damage or destroy a major city as evidenced by the explosion over Chelyabinsk, Russia, this past February of a meteor no bigger than a large truck, which injured more than 1,000 people.
With current space technology, scientists know how to deflect the majority of hazardous near-Earth objects. But prevention is only possible if nations work together on detection and deflection. Learn about the risks and the steps that are needed to avoid these potential natural disasters from a group of astronauts and cosmonauts who recently helped develop recommendations to the United Nations for defending Earth from asteroid impact.
In July 2012 on the anniversary of the Tunguska Asteroid impact, the B612 Foundation announced the Sentinel Mission to detect and track the million asteroids with the potential to destroy any major city on Earth. In partnership with Ball Aerospace, the leader in infrared deep space telescopes – the same company that built the corrective lens for the Hubble Space Telescope, the Spitzer and Kepler Space Telescopes – the B612 Foundation announced its plans to built, launch and operate a deep space telescope with an infrared lens – the first private-sector deep space mission in history.
