EGS Program Responsibilities

The EGS Program will perform payload integration for payloads flown on the SLS launch vehicle by physically integrating the payload and SLS flight hardware at the launch site for processing. This function includes evaluation of payload ground requirements, performing coordination to meet these requirements, KSC-wide physical integration activities and SLS ISPE hardware processing at the launch site. The EGS Program coordinates with the SLS Program to support payload ground activities and SLS Program integration activities including EGS Program representation to ensure cross-program integration.
EGS is responsible for spacecraft/payload physical encapsulation and integration onto SLS, launch site processing, launch control, range safety and ground requirements assessment/validation that will be executed as identified in mission-specific documents as applicable. EGS will assign a Launch Site Integration Manager (LSIM) to act as the launch site ground system point of contact for payload. In coordination with the SLS PIM, the EGS LSIM will engage with the spacecraft/payload during all phases of its development and integration, including initial feasibility assessments and applicable payload life cycle reviews.
Spacecraft/Payload Responsibilities

In order to ensure initial compatibility with SLS and overall mission feasibility, SLS encourages the spacecraft/payload developer to define its needs with SPIE as early in the process as possible. The SLS Accommodations Demand Model Input Template (ADMIT) survey shown in Appendix B is a short spacecraft/payload questionnaire that can be used as a guide to initial dialog and evaluation between SLS and a potential spacecraft/payload developer. Typical information includes, but is not limited to, desired launch date; principal points of contact; trajectory requirements; mechanical and electrical interfaces; thermal and dynamic environments; physical access; propulsion systems; batteries, transmitters and receivers; electro-explosive devices; nonelectrical ordnance and release devices; contamination requirements and orbit injection conditions.
After initial feasibility and interest for SLS accommodation is established, the spacecraft/payload defines its required SLS interfaces and accommodations. Typically, this is done through development of a unique spacecraft/payload “launch vehicle” Interface Requirements Document (IRD), or equivalent. If the spacecraft/payload does not have this type of documentation, the PIM and LSIM, will help the spacecraft/payload document its accommodation and service requirements.
Once formally manifested by ESD, the spacecraft/payload will be responsible for supporting SLS integration activities and participating in associated reviews in a phased manner to ensure safe and successful integration as detailed in Table 8-1. Unless otherwise noted, the SLS PIM and/or EGS LSIM will help develop documentation and represent the spacecraft/payload at other NASA required mission reviews not shown in Table 8-1. Opportunities for spacecraft/payload involvement in these other reviews will be arranged on a “by exception basis” by the PIM/LSIM.

Flight Readiness Review
launch-minus integration documents and milestones required between the spacecraft/payload and
the SLS Program. Each spacecraft/payload will have a unique integration schedule based on the
relative complexity of their system. For more complex spacecraft/payloads, the formal process
could begin when manifested as early as 48 months prior to launch (e.g., PPL or CPL). For less
complex spacecraft/payloads, the process can nominally begin as late as 36 months prior to launch
(e.g., SPL). SPIE, EGS and spacecraft/payload will negotiate and agree to the overall integration

defines SLS and the spacecraft/payload roles and responsibilities, interfaces, standard services, any
non-standard services, deliverable exchanges and the overall schedule for successful integration
and launch. The PIA is developed by the PIM and coordinated with the spacecraft/payload, with
revisions negotiated and agreed to by all parties as needed. SPIE will work with ESD, ESG and the
spacecraft/payload early in the development process to develop a draft PIA using the
spacecraft/payload IRD or equivalent document; all parties will agree to a draft of the document
prior to formal manifesting. When ESD manifests the spacecraft/payload on SLS, the PIA will be
baselined. Baselining the PIA formally starts the SLS-spacecraft/payload integration process.

controls and defines each side of an interface (SLS or spacecraft/payload) for hardware, GSE,
software and environment compatibility. It identifies required modifications to or new design of

ICD, a verification plan will provide one-to-one mapping of spacecraft/payload requirements to a particular compliance method for all phases of operations (e.g., ground processing, lift-off, in-flight, SLS separation events). The verification plan provides instructions and guidelines to verify safety and interface compatibility of the as-built SLS vehicle and spacecraft/payload hardware and software. The success criteria and methods of verification will be in the form of Detailed Verification Objectives (DVO), outlining the type or proof required for closeout (e.g., test, analysis, demonstration, inspection, similarity, and/or validation of records).
Payload Unique Safety Requirements Document (SRD)

A SLS safety representative establishes the safety policy and requirements applicable to SLS spacecraft/payload for a specific mission in the payload unique SRD. Its typical scope starts at payload delivery at the launch site and continues through ascent until end of the Orion mission (for Co-Manifested Payloads and Secondary Payloads on an Orion mission), or until upper stage disposal (for Primary Payloads and Secondary Payloads on an uncrewed mission). For the ground processing phase, the payloads must also comply with identified ground processing hazard requirements as identified in this document. Verification results of these payload ground and flight processing/operations hazards will be reviewed at the relevant phase Payload Safety Reviews.
Payload Unique Launch Site Support and Requirements Document
(LSSRD)

The EGS payload unique LSSRD provides an overview of spacecraft/payload requirements for each individual payload such as facility footprints, lifting hardware, Ground Support Equipment (GSE) required, payload specific processing phases, and standard/non-standard services needed. The EGS lead for the mission-specific LSSRD development will be the LSIM who will work with the payload developer. Generally, there are three phases of payload-specific LSSRD development: Preliminary LSSRD no later than Launch-36 months that contains the complete requirements known up to that point (will be continually updated until ready for baselining); Baseline LSSRD typically by Launch-24 months that contains final Non-Standard Service (NSS) requests, as well as the requirements and commitments known up to that point (revisions to this baseline version may occur through Launch-12 months); and the As-Flown LSSRD published after launch which incorporates any support and/or requirement changes that occurred after the Baseline LSSRD. The EGS Program and the spacecraft/payload approves the baselined version of the LSSRD; this version provides the basis to develop the EGS Program Requirements Document that is used to obtain commitments from suppliers to provide ground support requested.
Program Requirements Document (PRD)

A PRD is developed and comprised of a collection of payload support requirements related to products, commodities, and services, required to perform payload processing, test, and operations. These support requirements may include propellants, fluids and gases, commodity purity testing, ordnance storage and handling, security services, etc. The payload specific PIA, ICD, PSR, and LSSRD are utilized to develop the PRD. The PRD support requirements will then be communicated to the proposed suppliers to obtain payload support commitments.
Payload Operations & Maintenance Requirements Specifications (OMRS)

Any spacecraft/payload ground operations or integration task required after hardware turnover to EGS at KSC not documented through a PRD or in released engineering products will be documented through an OMRS. Payload OMRS will communicate detailed ground processing requirements to be implemented via work instructions in Work Authorization Documents (WADs) and application software to support launch processing activities such as integrated testing, servicing, operations, maintenance, launch countdown and recovery (as applicable). OMRS may be used for operations and maintenance (O&M) requirements for provided GSE unless O&M requirements are documented in manuals or other released engineering documents.
Payload Launch Commit Criteria (LCC)

LCC represent a single authoritative requirement source to verify the launch configuration supports mission objectives while maximizing launch probability and mission success, and ensuring the safety of ground personnel and flight crew safety. Inputs will be gathered via the SLS PIM and coordinated with EGS. Inputs will be used to support the development of Ground & Flight Application Software (GFAS), as a source of identifying credible anomalies for launch team simulation training models, and to help define the necessary launch countdown response/safing steps in emergency or contingency operations.
Payload Safety Reviews (PSRs)

PSRs will be phased over time and require information to perform analysis efforts that include, but are not limited to, payload handling and physical processing hazards, RF interference, ascent hazard, debris characteristics for input to unique range safety data, joint loads and environments, payload recontact analysis (nominal mission scenarios), etc. The spacecraft/payload will be required to participate in these and support data requests from the Payload Safety Review Panel (PSRP). Flight and ground safety requirements will be documented in the SRD and will form the basis of verification according to the corresponding DVO. See Table 8.1 for a more detailed list of typical data shared at PSRs.
Payload Flight Operations Timelines, Flight Rules and Procedures

The PIM will assist the spacecraft/payload in documenting flight operations related planning and requirements development activities. This will include identifying nominal and off nominal payload operations during SLS ascent, orbit, injection, payload separation, and upper stage disposal maneuvers as well as post upper stage disposal in the case of applicable Secondary Payloads. These results will be used as inputs to develop relevant payload timelines, Flight Rules, certifications, and associated procedures to support related mission training and ground console activities. They will be evaluated with support from FOD and presented at applicable reviews (e.g., Flight Operations Review) and incorporated in other documents (e.g., OMRS) as needed by the PIM on behalf the spacecraft/payload.
The SLS integration process has been developed to efficiently mesh with the spacecraft/payload’s schedule. This schedule (reference Figure 8-1) should be compatible with the spacecraft/payload’s milestone reviews (e.g., SRR, PDR, etc.), and, at a lower level, by the hardware and trajectory/mission target definition receivables and deliverables. The integration process will formally start post-ESD manifesting, with a baseline PIA between SPIE and the spacecraft/payload developer. The SLS integration process has been developed to effectively mature the integrated system through a series of system-level analyses and evaluations, each more rigorous than the previous. Throughout the integration process, with the support of the SLS PIM and EGS LSIM, the spacecraft/payload will participate in the working group and review activities described below.
Spacecraft/Payload Early Integration Studies

SLS encourages the spacecraft/payload to establish a dialogue with SPIE as early as possible to evaluate mission feasibility and design, unique requirements and unique hardware to support the spacecraft/payload’s milestone reviews. SPIE will establish a point of contact for the spacecraft/payload in coordination with EGS until a PIM is formally designated. Prior to a manifest decision, the SPIE office will arrange for regular spacecraft/payload working group or technical interchange meetings (TIMs) to focus on special topics to drive initial information required for spacecraft/payload and SLS integration planning. SPIE will arrange for these meetings to be held at regular intervals (e.g., monthly, quarterly, semi-annually) to define accommodation points of departure, as well as update the spacecraft/payload and SLS management on overall status. Findings from these meetings are used by the spacecraft/payload developer to support development of their SLS IRD, and by SPIE to support development of a draft PIA. Figure 8-1 shows this to nominally begin at L-60 months for PPL/CPL; in reality it will depend on the spacecraft/payload’s level of design maturity and readiness to engage with SLS.
Spacecraft/Payload Integration Reviews (SPIR)

SLS SPIE SPIRs ensure feasibility/compatibility of the spacecraft/payload to SLS ISPE accommodations and operational requirements and are aligned to spacecraft/payload lifecycle reviews (e.g., PDR, CDR, etc.). While SPIR 1 through 4 are shown as an example, the number and timing of these may vary based on spacecraft/payload, SLS, and mission requirements.
SPIR 1 will showcase the results of SLS system level vehicle and spacecraft/payload analyses for the mission. This will include defined vehicle accommodations such as the Payload Adapter, USA or PLF, as well as design environments identified during early integration activities. SPIR 1 results will be documented in a preliminary version of the SLS-Spacecraft/Payload ICD. SPIR 2 will review status of a more mature system, identifying interface changes on either side of the vehicle interface (SLS or spacecraft/payload). SPIR 2 results will be documented in a draft of the SLSSpacecraft/Payload ICD. SPIR 3 will review the results of an “as-built” integrated system level evaluation of the SLS and spacecraft/payload hardware design. SPIR 3 results will be documented in a baselined version of the SLS-Spacecraft/Payload ICD. A final SPIR (represented by SPIR 4) will review integrated verification data from the spacecraft/payload and SLS hardware such as the Payload Adapter, USA, or PLF. Successful SPIR 4 results will support having an effective spacecraft/payload Pre-Ship Review prior to EGS handover and acceptance.
