The Space Exploration Group Guidance, Navigation, and Control (GN&C) team is a high performing group executing challenging tasks to design and integrate GN&C systems for projects ranging from CubeSats to NASA’s Space Launch System (SLS). We are searching for highly qualified candidates to support the design, development, and oversight of the Human Lander Systems (HLS) Program in the Control Systems Design and Analysis branch at NASA’s Marshall Space Flight Center as the Deputy GN&C POC for SpaceX. The role will focus on GN&C discussions with SpaceX’s GN&C lead about everything GN&C, such as orbit insertion, decent guidance/landing, controllability, rendezvous, proximity, operations and docking (RPOD), manual steering, etc. This exciting work will serve as a critical step in sending humans back to the Moon, Mars and beyond! More detailed responsibilities include but are not limited to: • Acts as a NASA GN&C POC and interfaces with NASA’s HLS partners and cross-program organizations (Orion/Gateway/SLS). • Works closely with partner and cross-program organizations to resolve open requirements, and assist requirement maturation, seek understanding of a partner’s design/test data, potentially participate in partners’ tests, and lead Working Group meetings between partner and cross-program organizations. • Develop, track, and communicate HLS GN&C risks, concerns, and watch items associated with a particular partner to the HLS program. • Develop, present, and execute the HLS GN&C discipline elevated insight plans, independent analysis conducted by the HLS GN&C discipline, to inform HLS of design/mission risks. Work with HLS mission segment leads to identify areas where elevated insight is needed. • Lead HLS-GN&C insight meetings, NASA-only and with a partner. Support other HLS meetings as needed, with partners and NASA-only. • Provide status of HLS GN&C key insight activities to HLS (SVS and SE&I), and MSFC-EV department on a weekly/bi-weekly basis • Steward insight plan execution, including planning and direct analysis products and their fidelity. • Supports insight development of Planning, Programming, Budgeting, and Execution (PPBE) cycles for the HLS GN&C discipline, which includes resource breakdown by center and branch needed by the HLS GN&C discipline to accomplish the insight plans. • Actively find NASA expert reviewers to assess key areas of partner risk. E.g. if an HLS partner is developing a GN&C sensor, seek expertise across NASA to review partner’s development plans to assess partners adequacy of qualification plans before certification for flight. • Ensure HLS GN&C resources are utilized effectively to cover high priority insight tasks, including leveraging support from NASA centers (LaRC, JSC, JPL, et. al.) with key GN&C expertise. • Work with potential university partnerships to enhance skills in Guidance and Control. A degree in Aerospace, Mechanical or Electrical Engineering or related field from an ABET accredited institution is required.
