The news from the Beijing space flight control center, at noon on October 17th at 12:56 in the control center of scientific and technical personnel, the Shenzhou eleven spacecraft successfully implemented the first long-range navigation control, raise the perigee height. At present, the Shenzhou eleven spacecraft operating conditions are normal, the astronauts are in good condition.
Shenzhou eleven spacecraft launched in October 17th at 7:30. After successfully entering the track, the control will be handed over to the Beijing space flight control center. During the course of the spacecraft in orbit, the center of scientific and technical personnel to carry out accurate control of the spacecraft and close monitoring.
According to the deputy chief engineer of the Beijing Aerospace Control Center Sun Jun introduced, for the traction spacecraft thousands of miles away after Tiangong two, the need for guidance and control center on the spacecraft 5 times distance. First of all, the center to raise the spacecraft perigee altitude, on orbit plane is modified, and then lift the lofty place of height, but also for the final round of the track and combination of correction. After five long distance navigation control, the spacecraft will arrive at the Temple No. two, after about 52 km below the position, establish communication empty two spacecraft into the autonomous control section.
Different with the previous rendezvous and docking mission, the rendezvous orbit and return orbit height than before the increase of 50 kilometers, will be the first assessment verification stage of rendezvous and docking space station and manned spacecraft return technology, will be the first assessment of the medium-term presence of astronauts ability. To this end, the central scientific and technological personnel to adjust the control strategy for the spacecraft.
