Our world is filled with all sorts of elementaldisasters that annually take a lot of lives and cause great damage to property. Thanks to a variety of detectors and warning systems, people have already learned how to quickly respond to natural disasters and reduce their consequences to a minimum, but humanity still has no experience of salvation with a sudden fall of an asteroid. In this regard, the planetary defense coordination bureau and space agencies NASA and ESA decided to recreate the fictional asteroid crash scenario and develop an action plan.
The fictional script says that March 26employees of the Minor Planet Center discovered a hypothetical asteroid called 2109 PDC. At its 300-meter size, it is classified as a potentially dangerous asteroid, and by March 27, researchers figured out that it could collide with the Earth in eight years. However, by April 29, the probability of a collision increased sharply, and the space agencies were faced with the task of avoiding a catastrophe.
The purpose of this rehearsal is to have the agencyable to quickly develop a plan of action and establish communication between various space agencies. Researchers will empirically see how, in the event of a risk of an asteroid falling, it is necessary to act both as officials of space agencies and ordinary people.
Such experiments have already been carried out before;there were six of them. Thanks to them, the researchers found out that NASA employees place great emphasis on more accurate prediction of the asteroid's motion by observing its orbital route and physical characteristics. Probably during the new event, researchers will make other discoveries.
We will conduct periodic exercises with an ever-expanding range of US government agencies and international partners. For us, this is a great way to learn how to work together.
