After long six years interval, Kennedy Space Center (KSC) again get the taste of flame and smoke on its historic launch site on pad LC-39A. Nearly six years ago on July 8 in 2011, NASA made their final shuttle program using Space shuttle" Atlantis" from the same site.
Where this final space shuttle program is a logistic support mission in ISS (international space station) and then there are no space mission conduct in this platform until SpaceX resume with their Falcon 9 rocket engine "static fire" test for SpX-10 Dragon resupply mission to the International Space Station that occurred at 16:30 local time on Sunday, February12 which halted after its rocket explosion last September and finally rescheduled on February 18, around 10 am(previously in November 2016).
SpaceX especially started their commercial space launch from the coast at Cape Canaveral Air Force Station's Launch Complex 40, but after several damages of launch pad due to AMOS-6 static fire mishap on 1 September 2016, the readiness of LC 39A quickly catapulted to the top of the priority list for SpaceX.
The reason behind the delay is not only due to the rocket explosion but also a complex and extensive modification for shuttle era- LC39A PAD and also space craft including the flame trench, new fueling system, and a sound suppression system and Merlin 1D engines for Falcon 9 and Falcon Heavy rockets. The most visible of these changes involved the construction of the Horizontal Integration Facility (HIF) on top of the former crawler way inside the pad perimeter gate as well as the installation of rainbirds in dousing the pad and rockets with sound suppression water.
Now SpaceX hopes that they may soon be ready to resume launches from Florida after PAD modification and a new system installed in LC-39A launch site and t they may also be able to launch every two or three weeks, to work through its backlog of missions.
