Hi Irene - thanks very much for following up on this. We can now share the confirmed list of NASA team members, though the team may request or bring in additional support as technical questions arise:
Barbara Grofic, program manager, Astrophysics Project Division, NASA Goddard (NASA lead)
Patrick L. Crouse, Hubble project manager, NASA Goddard
Brian J. Roberts, robotic technologist, Satellite Servicing Projects Division, NASA Goddard
Jennifer J. Wiseman, Hubble project scientist, NASA Goddard
David N. Haskins, Hubble mission operations manager, NASA Goddard
Jackie Townsend, program manager, Astrophysics Strategic Missions Program, NASA Goddard
NASA informed ESA about the study and will update them as it progresses. The team may request technical expertise from ESA as well.
