About 25 minutes after liftoff, the satellite separated from the rocket and entered an Earth-Moon transfer orbit with the perigee at 200 km and the apogee at about 400,000 km. The solar panels and the communication antennas were unfolded. Queqiao is expected to enter a halo orbit around the second Lagrangian (L2) point of the Earth-Moon system, about 455,000 km from the Earth. It will be the world's first communication satellite operating in that orbit.[/i]</BLOCKQUOTE> <center><a href="http://www.collectspace.com/review/cnsa_queqiao_launch01-lg.jpg" target="AirLock"><img src="http://www.collectspace.com/review/cnsa_queqiao_launch01.jpg" width="400" height="258" border="0"></a></center>
