5.4. Payload Integration
While SpaceX does not require the payload to be at the launch site until two weeks prior to
launch, the Payload Processing Facility (PPF) will be made available for payload operations for
up to 3 weeks prior to launch at each of our sites. Additional time in the processing facility may
be available as a non‐standard service.
Figure 5‐11 – SLC‐40 Payload Processing Clean Area in Hangar
The PPF is a designated Clean Area within the hangar. A 33 ft tall clean area curtain provides
separation from the launch vehicle side of the hangar, while allowing the 34 ft bridge cranes
access to the entire hangar. An additional heating, ventilation and air conditioning (HVAC)
system keeps the PPF at Class 100,000 or better. All payload activities including equipment
unload, unpacking/packing, payload checkout and hypergolic fueling may be performed in this
area.
SpaceX will monitor relative humidity, temperature and cleanliness in the payload processing
facility, with the exception of periods when the satellite is mated to the second stage and
during launch vehicle maneuvering on the pad.
As a non‐standard service, SpaceX will help arrange the use of AstroTech facilities near CCAFS
for payload processing.
5.4.1. Integration Schedule
At approximately launch minus 18 days, the integration process begins (see Figure 5‐14) and
includes the following:
• The payload is vertically integrated onto the payload adapter
• The payload and adapter are then installed on the breakover fixture, rotated
horizontally and encapsulated by the fairing in the PPF (NOTE: SpaceX has the capability
to encapsulate a payload in either a vertical or horizontal position using an
