Exploration Systems Projects (ESP) was established by GSFC in March 2006 and was chartered to serve as the focal point for the Center's implementation activities within the Exploration Systems Mission Directorate's (ESMD) Constellation Program. The ESP team continues to grow and make significant contributions in a variety of disciplines spanning project management, systems engineering, disciplined engineering, and mission assurance. The ESP Office has led efforts to define system architectures in avionics, communications and navigation. These architectures will enable Exploration beyond Low-Earth Orbit (LEO) as NASA continues to shape its Exploration activities. The ESP Office also supports utilization efforts to advance technologies and capabilities using ISS and commercial accommodations; technologies that will help expand human and robotic presence as space exploration moves to destinations beyond ISS and LEO.
