At the Baikonur Cosmodrome in Kazakhstan a Proton-M rocket with DM-03 upper stage, carrying three Russian Glonass-M navigation satellites went out of control, exploded and crashed at 8:38 AM local time, July 2 2013.
The rocket propellant used is the hypergolic oxidizer dinitrogen tetroxide with the toxic and carcinogenic fuel unsymmetrical dimethylhydrazine, which leads to the brown smoke, massive fireball, and inevitable environmental contamination during the crash.
