NASA/GSFC plans to issue a Request for Quotation (RFQ) for participation in the replacement and modernization of the Guidance Navigation and Control Center (GNCC) mission analysis and planning systems. This procurement is being conducted under the Simplified Acquisition Procedures (SAP). NASA/GSFC intends to have Johns Hopkins University/Applied Physics Laboratory (JHU/APL) participate in this replacement and modernization of the GNCC mission analysis and planning systems. This participation requires broad experience and expertise in the conceptualization, design, and implementation of mission analysis, mission planning, and trajectory design functions for a variety of scenarios including low Earth orbiting, geostationary, highly eccentric, libration point, lunar, and interplanetary (including asteroid and comet rendezvous) missions. Through a wide range of flight projects, JHU/APL has developed and demonstrated broad experience and expertise in conducting mission analysis and planning functions for a variety of mission scenarios. In addition, JHU/APL has unique experience and expertise with asteroid and comet rendezvous mission design and implementation as demonstrated through the comet rendezvous mission design & implementation, the Nearth Earth Asteroid Rendezvous (NEAR), and Comet Nucleus Tour (CONTOUR) missions. As such, they are qualified to address this aspect of mission analysis and planning, providing general consultation, providing general consultation, serving as a Beta user, and supporting the validation and benchmarking of products being developed for use in support of these mission scenarios.
