On August 31, 2012, SpaceX completed a successful wet dress rehearsal, a launch readiness test which simulates the actual countdown of the Falcon 9 rocket. The rehearsal was in preparation for its first official cargo resupply mission to the International Space Station, which is currently targeted for October.

After completing the sequence, SpaceX unloads the propellants and returns the vehicle to a pre-launch state.

In the coming weeks, SpaceX engineers will review the data and prepare for a full static test firing, where the Falcon 9’s nine first stage engines ignite for a few seconds, with the vehicle held securely to the pad. That will mark the final major test before actual flight.

Once Falcon 9 is vertical, all personnel depart from the launch site and both stages are filled  with RP-1 fuel and liquid oxygen, as they would be for flight. Photo: SpaceX
