Engineering Services and Science Capability Augmentation (ESSCA)

Jacobs Engineering Services and Science Capability Augmentation (ESSCA) contract in support of NASA at Marshall Space Flight Center and Michoud Assembly Facility

The George C. Marshall Space Flight Center (MSFC) in Huntsville, Alabama is the U.S. government’s civilian rocketry and spacecraft propulsion research center. The largest NASA center, MSFC’s first mission was developing the Saturn launch vehicles for the Apollo moon program. MSFC has been the agency’s lead center for Space Shuttle propulsion and its external tank; payloads and related crew training; International Space Station (ISS) design and assembly; and computers, networks, and information management. The center also contains the Huntsville Operations Support Center (HOSC), a facility supporting ISS launch, payload, and experiment activities at the Kennedy Space Center (KSC). The HOSC also monitors rocket launches from Cape Canaveral Air Force Station when a Marshall Center payload is on board. MSFC has capabilities and projects supporting NASA’s mission in three key areas: lifting from Earth (Space Vehicles), living and working in space (ISS), and understanding our world and beyond (Advanced Scientific Research). On the ESSCA contract, Geocent has been actively supporting MSFC since 2008.

The Challenge

MSFC is NASA’s designated developer and integrator of launch systems. The state-of-the-art Propulsion Research Laboratory serves as a leading national resource for advanced space propulsion research and has the engineering capabilities to take space vehicles from initial concept to sustained service. In early March 2011, NASA Headquarters announced that MSFC would lead the efforts on the Space Launch System (SLS) vehicle that will carry large, man-rated payloads beyond low-Earth orbit. In support of the Center and all its primary objectives the MSFC established the Engineering and Science Services and Capability Augmentation (ESSCA) Services Contract. The purpose of the ESSCA Services Contract is to obtain services necessary to provide MSFC with the continuous requirement for engineers, scientists, and technicians necessary to support the Engineering Directorate, Science and Technology Office, Flight Programs and Partnerships Office, future programs/projects, and other offices that have similar needs. The efforts needed are dependent upon fluctuating work requirements of the Center relative to commensurate civil service personnel. The services requested include a wide range of engineering and science disciplines deployed among a large number and variety of MSFC activities. Geocent’s contract with Jacobs for the NASA MSFC support contains full life cycle engineering scope

The Solution

Geocent has performed services required to conduct conceptual studies and analysis, requirements definition, preliminary planning, evaluation of alternative technical approaches, and associated costs in support of NASA MSFC Directorate Organizations. We worked closely with MSFC Engineering to complete requirements analysis, execute cost/cost performance trade-off and feasibility analysis, develop training requirements, and generate requirements documentation.

Geocent has provided design, development, analysis, integration, simulation, modeling, and testing of aeroacoustics; aerodynamic flight control surfaces; venting; aerodynamic heating; plume induced pressure; forces and heating; Guidance, Navigation and Control (GN&C) flight systems; thermal analysis and controls; flight mechanics; fault management; dynamics; loads; strengths; avionics; sensors; aerodynamic testing and analysis; analytical tool development and control systems. In addition, Geocent has provided multi-body integrated vehicle loads analyses for all ground, flight, in-space, and return flight events (i.e., rollout, on pad pre-launch, liftoff, first stage flight, second stage flight, separation, docking, reentry, landing, and water impact).

Geocent has provided testing of space systems, propulsion systems, space transportation systems, scientific research equipment, test articles, and special equipment for all programs. We provided load analyses for ground, flight, in-space, and return flight events including launch, liftoff, first stage flight, second stage flight, separation, docking, re-entry, landing, and water impact. Geocent also supported the design, development, assembly, test, analysis, modeling and/or simulation of development hardware, prototype hardware, flight hardware, ground hardware, payloads, subsystems, science investigations, and exploration initiatives.=

Geocent Logistics Engineers/Analysts have supported NASA MSFC through the performance of Logistics Support Analyses necessary to ensure that MSFC hardware and associated support and production equipment are maintained and adequately provisioned throughout their lifecycles.

Geocent has supported NASA MSFC with the planning, budget, contract, and systems/program management functions required for fabrication and purchase of fixtures, equipment, tooling, and analytical tool development required for the operation, maintenance, and testing of MSFC Manufacturing and Assembly (M&A) facilities and capabilities.

On the ESSCA contract, Geocent has been actively supporting MSFC since 2008.
