SpaceX Falcon 9 preparing for Static Fire ahead of SES-9 launch
SpaceX’s Falcon 9 rocket is set for her Static Fire test on Monday, a dress rehearsal milestone ahead of Wednesday’s launch of the SES-9 satellite. The test is taking place at SLC-40, at the same time as work begins at LC-39A to remove the Shuttle-era Rotating Service Structure (RSS) from the site of future SpaceX launches.
The Static Fire test validates the health of the launch vehicle, allowing for SpaceX management to approve the final flow to launch day.
Numerous requirements have to be successfully proven via such a test, such as the engine ignition and shut down commands, which have to operate as designed, and that the Merlin 1D engines perform properly during start-up.
It also serves as a full dress rehearsal for the launch team and will provide another test of SpaceX’s recent upgrade to a supercooled propellant pad systems that resulted in a number of challenges ahead of its debut use during the OG-2 launch.
Once the required engine and vehicle data has been collected, detanking operations will follow, before the rocket is lowered onto the Transporter Erector (TE) and rolled back to the hanger.
The Static Fire’s data review will be fed into the Launch Readiness Review (LRR) – a key meeting that will ultimately confirm the launch date.
The first attempt is currently scheduled for Wednesday, within a window that ranges from 18:46 to 20:23 Eastern. A second opportunity is available on Thursday, within the same launch window
