6.3.3. Mission Reviews
In addition to the MIWG and RWG, a number of mission reviews are conducted as required to ensure the
launch service and payload integration activities are progressing according to schedule. During the inte-
gration process, mission reviews are held to provide coordination with a broader audience of mission and
management participants who do not participate in either of the Working Groups. Due to the variability in
complexity of different payloads and missions, the content and number of these reviews are tailored to
customer requirements.
6.3.3.1. Mission Design Reviews (MDR)
Typically, two mission-specific design reviews are held to determine the status and adequacy of the
launch vehicle preparations. Designated MDR-1 and MDR-2, these design reviews are held at 6 months
and 10 months, respectively, after Authority to Proceed (ATP). They are each analogous to a develop-
ment program’s Preliminary Design Review (PDR) and Critical Design Review (CDR), but focus on mis-
sion-specific and mission-unique elements of the integrated launch vehicle effort.
6.3.3.2. Readiness Reviews
During the integration process, readiness reviews are held to provide the coordination of mission partici-
pants and gain approval to proceed to the next phase of activity from senior management. Due to the
variability in complexity of different payloads, missions, and mission assurance categories, the content
and number of these reviews are tailored to customer requirements. A brief description of each readiness
review is provided below:
a. Pre-Ship Readiness Review (PSRR) — Conducted prior to committing flight hardware and per-
sonnel to the field. The PSRR provides testing results on all formal systems tests and reviews the
major mechanical assemblies which are completed and ready for shipping at least L-60 days.
Safety status and field operations planning are also provided covering Range flight termination,
ground hazards, spaceport coordination status, and facility preparation and readiness.
b. Incremental Readiness Review (IRR) – The quantity and timing of IRR(s) depends on the com-
plexity and Mission Assurance Category of the mission. IRRs typically occur 2-12 months prior to
the launch date. IRR provides an early assessment of the integrated launch ve-
hicle/payload/facility readiness.
c. Mission Readiness Review (MRR) — Conducted within 2 months of launch, the MRR provides
a pre-launch assessment of integrated launch vehicle/payload/facility readiness prior to commit-
ting significant resources to the launch campaign.
d. Flight Readiness Review (FRR) – The FRR is conducted at L-10 days and determines the rea-
diness of the integrated launch vehicle/payload/facility for a safe and successful launch. It also
ensures that all flight and ground hardware, software, personnel, and procedures are operational-
ly ready.
e. Launch Readiness Review (LRR) — The LRR is conducted at L-1 day and serves as the final
assessment of mission readiness prior to activation of range resources on the day of launch.
6.3.4. Customer-Provided Documentation
Integration of the payload requires detailed, complete, and timely preparation and submittal of interface
documentation, data, models, and drawings. The major products associated with these documents are
divided into two areas: those products that are provided by the customer, and those produced by Orbital.
Customer-provided documents represent the formal communication of requirements, safety data, system
descriptions, and mission operations planning. Documentation produced by the customer, as detailed in
