Seminar - The Great Gateway Escape: Departing Flows in Near Rectilinear Halo Orbits - Jan. 31

Gateway Mission Design Integrated Systems Lead at Johnson Space Center
Friday, Jan. 31 | 12:30 P.M. | AERO 12O
Abstract: The Gateway is NASA’s next human outpost in space, a staging location for missions beyond Earth orbit and a proving ground for deep space technologies. The Gateway will fly in a Near Rectilinear Halo Orbit (NRHO), a cislunar orbit that depends on the simultaneous influence of the Earth and the Moon. The NRHO has many advantages, including inexpensive transfers to and from Earth, favorable communications with Earth and the lunar south pole, inexpensive orbit maintenance and attitude control, and access to the lunar surface.Ìý Diane Davis will deliver an overview of the Gateway mission, including Artemis and human lander concepts.Ìý She’ll then discuss mission design challenges and opportunities that arise in a multibody regime, with a focus on the complex departing flow from the NRHO and how visualization techniques are used to ensure safe departures from the Gateway to the lunar surface or heliocentric space.
