Council of the Russian Academy of Sciences (RAS) has approved a project to establish a system to track approaching Earth and potentially dangerous space objects. The project was named DSDA (detection system daytime asteroids) and start work on it is scheduled already for next year.
The system will keep track of celestial bodies with a diameter of more than ten meters for four hours before the estimated time of entry into the atmosphere. To perform this task will be built the satellite, which is then sent to one of the Lagrangian points L1 is located between the Earth and the Sun at a distance of 1.5 million kilometres away from our planet. It is said that at the moment none of the existing ground facilities impossible to find a space object is moving toward Earth from the Sun.
According to one of participants of the project Boris Shustov:
“Optical Instruments illuminates and radio telescopes are usually designed for a review within a few thousand kilometers from the Earth. The probability that a body like the Chelyabinsk meteorite destroy the city, of course, small. But warn of such events is necessary. Therefore, for the expert group on space threats, the task was to offer a means of discovery of the bodies coming from the daytime sky.”
DSDA project will be able to recognize space objects with a diameter of 10 meters for 4 hours prior to the estimated entry into the Earth’s atmosphere. The budget of the project is 10 million rubles. In addition, within the framework of the establishment of the satellite system will be held on computer modeling of complex DSDA. It will take another 2.5 million rubles. Start the project, we recall, is scheduled for 2017.
