According to ballistic and navigational support service specialists calculations progress M-26M cargo vehicle thrusters were ignited at 03.30, Moscow time, and have been operating for 1922 seconds. As a result of this maneuver the station got velocity increment of 1,75 m/s.
After this maneuver the station’s orbit increased by 3,2 km and amounted to 401,88 km.
After station adjustment ISS parameters are as follows:
-minimum altitude – 400,76 km;
-maximum altitude – 417,75 km;
– orbit time – 92,54 min.;
– orbit inclination – 51,66 degrees.
The orbit was adjusted to form working orbit for Soyuz TMA-15M spacecraft landing.
