Charged with launching the Progress M-12M Russian craft to resupply the International Space Station, the Soyuz-U rocket failed its final mission on August 24th, 2011. The unmanned rocket launched from Baikonur Site 1/5, but 325 seconds into the flight, malfunctions started to threaten the success of the mission. One rocket engine, specifically the RD-0110 engine, failed in mid-flight, causing the automated control to terminate the rocket’s thrust. With no upward momentum, Soyuz-U and Progress M-12M never achieved orbit and instead crashed over the Altai Republic in Russia, marking the first time a Progress craft had failed to reach orbit. Further inspection of the defunct craft pointed to a blocked fuel duct that ceased operations in the engines.
