BLITS Russian satellite collided with the wreckage of Fengyun-1C in orbit

The collision of two space objects of terrestrial origin - Russian microsatellite BLITS, working with the laser probing of international class, with a fragment of the Chinese weather satellite Fengyun-1C, destroyed six years ago when testing anti-satellite weapons - occurred on the night of March 9, said Thomas Kelso, an expert of the American Center Space Standards and Innovation.

According to information published on the website of AGI, it is not the first encounter man-made objects in space. In 2009, faced orbit satellites Cosmos 2251 and Iridium 33.

The staff of the International Laser Ranging Service (ILRS) had registered a sharp change in the parameters of the orbit-owned Russian satellite BLITS (Ball Lens In The Space), according to an expert. Created by the Scientific and Production Corporation "Systems Precision Instrument" satellite was launched into orbit for the first time in 2009. The object is a ball-reflector glass weighing 7.5 pounds, the purpose of which is to work with ground-based laser range finders.

The experts studied the parameters of its orbit, discovered on January 22 around 7.57 GMT, the sudden change in the period of the satellite around the axis from 5.6 seconds to 2.1 seconds. It was also noted decrease in semi-major axis of the satellite orbit by 120 meters. Weight of the "drummer", according to Kelso, could not be more than 0.08 grams.

After checking the database space debris, the Center’s specialists have found that close to BLITS for 10 seconds to change the orbit was to fly the device chip Chinese Fengyun-1C, which was destroyed in 2007 on the set of fragments in the course of China’s anti-satellite weapons test.

As noted on the site ILRS, additional observations are needed to determine the extent of damage BLITS, and the feasibility of further use of the machine.
