Space Launch Complex 40 is located at the northern end of Cape Canaveral, Florida. The launchpad is currently home to the Falcon 9 rocket, delivering both commercial and NASA payloads to low Earth orbit and beyond.
LC-40 was first used in 1965 with the maiden flight of the Titan IIIC. Between 1965 and 2005 there were 30 Titan IIC, 8 Titan 34D and 17 Titan IV launches. Notable payloads include the failed Mars Observer spacecraft, launched in 1992, and the Cassini-Huygens spacecraft, which launched in 1997 and arrived at the gas giant Saturn in 2004.
Since 2007 the launchpad has been leased to commercial launch provider SpaceX for their Falcon 9 rocket. The pad has conducted 13 Falcon 9 launches from 2010 to 2015. Among these launches there have been several successful missions to the International Space Station with the Dragon cargo spacecraft and a number of commercial satellite missions to both low Earth orbit and geostationary orbit. The only failure to note was the CRS-7 mission in late June, where the Falcon 9 rocket disintegrated shortly after lift-off.
SpaceX plan to retain the launchpad for many years to come. With the upgrades to SLC-39 expected to be complete by 2016, the Falcon Heavy and commercial crew involvement will not change how SpaceX use the historic launchpad.
