NASA has created a system alerts “asteroid attack.”

According to the newspaper Universe Today, it can detect any threat object five days before his fall to the Earth.

In 2011, the event dedicated to the presentation of the catalog of NEOWISE, NASA officials said today it is known only about five thousand asteroids with a size of approximately one hundred meters. However, the total number of large and medium-sized asteroid of a few tens of thousands. The number of small meteorites reaching the million.

Many asteroids already discovered by the astronomers, however, ground-based telescopes is insufficient to detect and identify other heavenly bodies.

Researchers are not immediately able to notice the Chelyabinsk meteorite, because at that time (winter of 2013) was almost impossible to detect a celestial body in advance of approaching the Earth.

That is why NASA, Russia’s Roscosmos and major space organizations and other countries are working to create systems of detection of asteroids to their dangerous proximity to Earth and plan to create a “space of defense”.

The first such invention was the Scout engineering system from NASA, designed and already tested this fall. With her help was able to detect the asteroid 2015 UR36 five days before his approach to Land, calculate the size, compute the distance at which he can approach.

Five days is a short time, but scientists previously discovered asteroids only a few hours before their fall. Five days to really take security measures, to predict consequences, develop a plan to prevent the fall of a celestial body.

By 2018, NASA plans to launch several micro-satellites NEA Scout, which should help researchers to fill the gaps in the predictions relative to the asteroids. If a celestial body approaching the planet, one of the probes will fly up to him, make images of the surface and analyze chemical composition.

Recall that recently the Council of the Russian Academy of Sciences space was sent to Roskosmos list of promising research projects. Among them was a project to monitor asteroids.

In Russia there is a similar invention that allows to predict the approaching asteroids that threaten the planet: “SODA”. Using this system it is possible to detect flying from the Sun asteroids larger than ten meters.
The fall of the Chelyabinsk meteorite was sudden for the reason that it could not see any one ground-based telescope before the entry of a meteorite in Earth’s orbit. He flew in the direction from the Sun and fell in the daytime, so it was impossible to see due to the light that “kills” the image. To see the celestial body, it was necessary to place the telescope between the sun and the Earth towards the planet.
