The spacecraft was launched on time at 14:41:46 UTC on 11 February 2013 from theBaikonur Cosmodrome inKazakhstan.[2]

Progress M-18M docked with thePirs at 20:35 UTC less than six hours after the launch. The successful docking climaxed the third successfulSame-Day-Rendezvous in the International Space Station history.[3]
Progress M-18M delivered about 346 kilograms (763 lb) of propellant, 50 kilograms (110 lb) of oxygen and air, 420 kilograms (930 lb) of water and about 1,368 kilograms (3,016 lb) of spare parts, science gear and other supplies (dry cargo) to the Space Station.[4]

Progress M-18M undocked from the ISS on 25 July 2013. The re-entry procedure started around 23:53 UTC, on 25 July 2013. The destruction occurred at 00:42 UTC, on 26 July 2013 in thePacific Ocean.[5]
