Abstract
SSP TIM 2 was conducted September 21 _t through 24 '_ with the first part consisting of a
Plenary session. The summary results of this Plenary session are contained in part one of this
report.
The attendees were then organized into Working Breakout Sessions and Integrated Product
Team (IPT) Sessions for the purpose of conducting in-depth discussions in specific topic areasand developing a consensus as to appropriate study plans and actions to be taken. The second
part covers the Plenary Summary Session, which contains the summary results of the WorkingBreakout Sessions and IPT Sessions. The appendix contains the list of attendees.
The objective was to provide an update for the study teams and develop plans for subsequent
study activities.
This SSP TIM 2 was initiated and the results reported electronically over the Internet.
The International Space Station (ISS) could provide the following opportunities for conductingresearch and technology (R&T) which are applicable to SSP:
Automation and Robotics Advanced Power Generation Advanced Power Management & Distribution (PMAD) Communications Systems & Networks
Energy Storage In Space Propulsion (ISP) Structural Dynamics & Control, and Assembly Wireless Power Transmission
1.0 Introduction and Background
MSFC is conducting a Space Solar Power Concept Definition Study for NASA Headquarters
in response to strong interest expressed in SSP outside the Agency.
UAH Propulsion Research Center hosted SSP TIM 2 to facilitate International participation
(Japan, Canada, and Germany) and open discussions with all data freely exchanged.
This TIM was conducted making maximum use of the lnternet and the MSFC Online Project
Management System, Virtual Research Center (VRC). For instance, the announcement,invitations, and agenda were put on the net. Other invitees not registered on the VRC were
contacted by electronic email.
The 550 Vu-graphs presented at this TIM will be made available through Joe Howell, MSFCProject Manager telephone No. (256) 544-8491, and Fax No. (256) 544-6669 or email
joe.howell@ msfc.nas_.gov.
A list of SSP TIM 2 attendees with their email addresses is contained in the Appendix. ThisExecutive Summary will be distributed by email and put on the MSFC Online Project
Management System, VRC.
2.0 Objectives
