Launch and docking

Progress M-07M was launched by a Soyuz-U carrier rocket, flying from Site 31/6 at the Baikonur Cosmodrome. The launch occurred at 10:22:28 UTC on 10 September 2010. The launch had previously been scheduled to occur at 11:11 UTC on 8 September, however it was delayed due to unfavorable weather conditions. After the launch the spacecraft reached a preliminary orbit of 195 by 238 kilometres (121 by 148 mi). A series of engine firings over the next two days guided Progress M-07M to the rendezvous.
