This workshop has been almost entirely a volunteer workshop. Funding grants are solicited, however. Interested participants are encouraged to email group or module chairs or authors for the areas you are interested in participating in. All modules will be subject to peer review by group leaders, designated reviewers and internet visitors. Other sites, listed below, will provide answers to frequently (& infrequently) asked questions The SSPW requests your help.
Authors, chairs and other participants are requested to assist in design of the content for their area. Illustrations should be kept small to reduce load times. Revision of this SSPW website and functional model will take place as engineering/financial modules become available from the group leaders and module authors, especially after their formal presentation at participating conferences. Engineering and financial peer review is also in progress. Please submit constructive comments concerting modules, activities or requests to the group or SSPW chairs, who will evaluate the engineering confidence level for each system design. The financial evaluation will be done by group 7. Please email the group and module chairs for full information about those specific activities. Additional module proposals, are listed at the core group pages. Only active and proposed active modules appear on this page.
1.
Energy collection to
bus - SPS photovoltaics and module construction.
Chair:
Co-chair: Geoffrey Landis, geoffrey.landis@grc.nasa.gov NASA Glenn Research Center
Module 1.13 – "SPS DC Electrical Distrinution"
Status: Complete
Author(s): Carlton Preble, consulting space power designer seapreb@ucnsb.net .
From the panel level collection taps to the transmission and breaker system to the antenna bus, with overload protection, voltage step-up and electrical system stability/security. High Temperature Superconducting transmission wiring (which must be kept in the SPS's perpetual shadow), is a key design feature.
2. SPS structural
design, orbital
mechanics, thermal vibration, stability and control.
Chair: Robert Loewy; chair, Aerospace Engineering Graduate division, Georgia Tech Robert.Loewy@aerospace.gatech.edu .
Co-chair: William Westphal, Technical Program Chair at the AIAA/ ASME Structures, Structural Dynamics, and Materials Conference WIWestphal@aol.com
Status: Under Construction
Author(s): Olivier Bauchau, Olivier.Bauchau@aerospace.gatech.edu .
Case 1 SSP - derived from the "Sun Disk" model developed by NASA for use in GSO. It assumes no lunar manufacturing component.
3. Robotics: Preview telerobotics, communications, automated & semi-autonomous machines.
Chair:
Co-chair: Paul Klarer, prklare@sandia.gov Sandia National Laboratory.Module 4.11 - " Tele-Robotic SSP Assembly process design "
Status: Under Construction (last updated 3/11/98)
Author(s): Darel Preble, computer systems interface designer, preble@netdepot.com
Assembling solar power satellites from components brought to GSO, this work is intended to be entirely automated or telerobotic, but will need communications support such as Teledesic, , or others might provide contractually - plus transportation.
5. Space Transportation - cost model for general use. :
Module 5.11 -"5*Star Booster: Launch & Construction for Space Solar Power"
Status: Ready for Review (last updated 2/11/98)
Launch and construction of the massive space structures required for Space Solar Power (SSP) requires careful attention to the inter-relationships of these two functions. The size of the launch vehicle will be dictated by the largest item which must be produced on Earth. A concept for a reusable, winged launch vehicle intended to achieve these functions will be presented along with a preliminary structural concept for the satellite itself, and for its deployment and assembly in space.

Transportation for Johnson Space Center.
Though not an SSPW module per se, this special competitive opportunity represents many public and private space transportation initiatives now driving lower cost space transportation. The X PRIZE will stimulate the development of commercial space travel by awarding a $10 million prize to the first private team to build and fly a reusable spaceship capable of carrying three individuals on a sub-orbital flight. http://www.xprize.org/
6. Lunar materials may ultimately be the lowest cost source for fabricating SPS photovoltaics, including protective coverglass, antenna, structural elements, hardware, housing, air lock, etc.,
