Teachings ESA response meteorite strike

After the Chelyabinsk meteorite became clear that the threat of a collision with a large cosmic body is real. Experts from the European Space Agency believe that you need to prepare to defend advance. 24-25 November 2014 ESA провело two-day teachings Space Situational Awareness (SSA) . Conditions were simulated with the sudden discovery of the asteroid heading for Earth. This is the first test of this kind of ESA.

The exercise simulated the situation for asteroids with a diameter of 12 meters (less than 19-meter Chelyabinsk meteorite 2013) to 38 meters (approximately as the Tunguska meteorite in 1908), which enter the atmosphere at a speed of 12 5 km / s.

The experts discussed what action should be taken in five critical time:

• 30 days before the collision;
• 26 days before the collision;
• 5 days before the collision;
• 3 days before the collision; li >
• 1 hour before the collision.
  The panelists discussed how the European institutions must respond to such a threat, with whom to share information and what kind. It was decided that the mass, size, and composition of the asteroid, as well as the approximate point of impact in the Earth can be predicted for the three days of clashes. Thus, for three days will become clear impact energy and the possible consequences. It was probably at this point can be prevented by local authorities and the population of the planet.
  
  For comparison, the Chelyabinsk meteorite in 2013 weighing about 12,000 tons and 19 meters in diameter entered the atmosphere at an acute angle at a speed of about 18, 6 km / s and exploded at an altitude of 25-30 km, releasing energy equivalent to the explosion of 480 kilotons of TNT. The shock wave damaged 7300 buildings, causing minor injuries to 1,500 people. Most of the victims - the curious, looking into the windows and cut into fragments of broken glass.
  
  In an emergency, the main task of ESA - provide local authorities with information about the time and place of impact, as well as other useful scientific information on the alleged consequences of the disaster.
  
  The exercise was attended by experts from ESA Germany and Switzerland. In 2015 it is planned to repeat the event, inviting experts from other countries. To the program attracted international agencies and organizations, including the UN. What do you think will disappear when the human civilization?
