Pegasus User’s Guide

(2)

Ferry mission: Payload integration is
conducted at VAFB and launch operations are
conducted from a non-VAFB launch location.

(3) Campaign mission: Payload integration and

launch operations are conducted at a site
other than VAFB.


For the baseline and ferry missions, spacecraft
pre-launch operations are conducted at Orbital’s
VAB, Building 1555, VAFB. For campaign style
missions, the spacecraft pre-launch operations are
performed at the desired launch site.

Before a spacecraft arrives at the processing site,
the payload organization must provide the
cognizant range safety office with certification that
the system has been designed and tested in
accordance with applicable safety requirements
(e.g., AFSPCMAN 91-710, Range Safety
Requirements for Baseline and Ferry Missions).
Spacecraft that integrate and/or launch at a site
different than the processing site must also comply
with the specific launch site’s safety requirements.
Orbital will provide the customer coordination and
guidance regarding applicable safety
requirements.

Figure 6-4 provides a matrix of the governing
safety requirements for demonstrated and planned
Pegasus payload integration flow. The Orbital
documents listed in the matrix closely follow the
applicable range safety regulations.
