Cloudy weather was initially going to obstruct the launch but the just 10 seconds before the launch he computer detected some issues in the rocket’s guidance, navigation and control systems. This aborted the launch.
With this third Falcon 9 rocket, SpaceX is planning to launch an Intelsat 35e communications station, the fourth in a series of high-power satellites. The satellite is planned to be in orbit around 22,300 miles above the Atlantic Ocean to give coverage in Latin America, Western Africa and the Caribbean.
SpaceX usually re-lands the Falcon 9 back on to the launch pad. However, the rocket is carrying the Intelsat 35e satellite, a payload heavy enough that SpaceX will not attempt a landing of the rocket’s first stage.
After this Falcon 9 launch there will be no more launches planned at the Kennedy Space Center till August 3 when the United Launch Alliance is planning to launch a communications and data relay satellite for NASA into space. SpaceX’s next launch is bound to happen on 10 August, 2017.
