MOSCOW. Nov 29 (Interfax-AVN) - Ballisticians of the Russian Mission Control Center, a unit of the Central Research Institute of Machine Building (TsNIIMash), discovered 74 encounters, which breached the 15-kilometer security perimeter of the International Space Station (ISS), in October 2013.
"The ISS had eight encounters with space objects with the minimal distance of less than four kilometers," a TsNIIMash spokesman told Interfax-AVN, quoting a report on the current condition of the near-Earth space as of late October.
TsNIIMash specialists received 41 warnings about space objects approaching the ISS from the Russian Space Control Center. One of them flew past the ISS at a distance smaller than 1.5 kilometers.
The Russian ballisticians received and analyzed 25 warnings about five approaches of space objects to the ISS from the Space Center Houston in the United States. Four warnings coincided with the calculations done by TsNIIMash specialists and the reports made by the Aerospace Defense Forces.
In addition, Russian ballisticians noticed six trajectories of space objects that breached the 15-kilometer security perimeter of Glonass satellites, in October.
