Joleroy says, "I am delighted to help perpetuate the important work being furthered in this series about Solar Power Satellites." "After thirty years of working in the aerospace industry I retired in late 1986. Today, I believe that the most important problem in our country's future is the alleviation of global planetary warming and the problems associated with obtaining sufficient energy to accommodate continued growth in the economy."

Born on 20 June 1936, Raghavan Gopalaswami, a mechanical engineer, received a Master of Science (M.S) Degree in Rocket Technology from the Cranfield University Institute of Technology, U.K. in 1970, and completed the Advanced Management Program of the Harvard Business School, U.S.A in 1984. He pioneered research, design and development of liquid propellant rocket propulsion systems in India all through 1960’s and 1970’s. He was twice recipient of Awards from the President of India for innovative contributions to rocket propulsion development.
He retired in 1994 as CEO of an aerospace industry. His focus since 1987 even after retirement has been on research and conceptual design of a new class of fully reusable spaceplanes using innovative "aerocryogenic" technologies and propulsion systems that create a multiplier effect on space vehicle mass ratios, enabling safe, affordable and direct ascent from earth to orbit in a single stage. These spaceplane designs, specifically intended for space solar power missions, were well ahead of time. He strongly believes that the time has now arrived for an integrated, international space solar power and spaceplane mission for resolving India’s crippling energy crisis, and other nations as well, while helping mitigate global warming.
Dr. Hsu was until recently head of the NASA GSFC risk management function, and was the GSFC lead on the NASA-MIT joint project for risk-informed decision-making support on key NASA programs, as GPM, LSS and the CxP etc. He was also a leading engineer/scientist in the Shuttle and Exploration Analysis Department at JSC in Houston, and led key projects such as the Shuttle PRA modeling & integration, SLEP and Shuttle upgrade trade studies. Dr. Hsu served on many agency and center expert panels supporting challenging SMA issues, including his key roles in the STS-107 (Space Shuttle Columbia) investigation team, the Return to Flight team, and ECO expert team for the Discovery mission.
Dr. Hsu has over 90 publications and is coauthor of two books and co-chair of several technical committees. He is frequently invited as a keynote speaker on many international forums, and is increasingly dedicated to frontier research ranging from human space exploration; solar energy to global collective intelligence and risk based policy-making on emerging environmental and energy security issues. Hsu holds a bachelors degree in Applied Math, masters degree in Operations Research and Statistics and a doctoral degree in Engineering Science.
As senior advisory of Aerospace Technology Working Group (ATWG) and a co-founder of Space Development Steering Committee, Dr. Hsu has been a strong advocate for SBSP for years and was instrumental in instigating the 2007 NSSO study on space solar energy and has contributed whole-heartedly to the great human endeavor of harnessing solar energy for sustainable human development.

Keith is a 56 year old mixed-signal integrated circuit designer in Beaverton, Oregon. Keith is CEO of SiidTech, which licenses silicon identification technology to semiconductor manufacturers. Keith is also an integrated circuit design consultant. Keith designed crossbar routing chips for Icube Design Systems, which were used by Cisco and others to route much of the internet in the mid 1990s. Keith helped write the IEEE 1149.4 mixed signal scan test standard, and received an award for a related presentation at the International Test Conference.
Keith has designed thin-film light valves for computer projectors. He deploys low power computer systems with high performance per watt. He is inspired by the nearby Solar World silicon solar cell factory (largest in North America), and nearby Intel's "DC bus data center" initiatives, aiming to increase data center efficiency. He is concerned that large data center projects in Oregon use prime greenfield industrial land and large amounts of power, while failing to alleviate high local unemployment. These interests and concerns led to server sky.
Keith is webmaster for Orcnet, the Oregon IEEE Consultant's Network. Keith is active in open source and the Portland Linux Unix Group. Keith's server hosts the dirvish disk-to-disk backup program, based on rsync and written in Perl.
Inspired by Arthur C. Clarke's novel Fountains of Paradise (but not his engineering or materials science), Keith invented the Launch Loop in 1981. This speculative space launch system can be built with existing technologies and launch thousands of tons into orbit per day at costs below $5/kg. No market yet exists for that much launch capability. The Launch Loop (http://launchloop.com) is attracting renewed attention from a new generation of space enthusiasts.
Space launch is risky and expensive, and the risks and costs must be reduced before large-scale passenger operations or complex construction projects become practical. Keith believes that the expansion into the universe will be funded by broadly- and strongly-felt near-term economic needs, driving the demand for millions of tons of automated cargo into orbit per year. Self-deployed arrays of tiny, interchangeable, mass-produced satellites is one way to accomplish large scale missions without orbital construction, eventually leading to the market demand that will pay for high volume, low cost launch systems. When these systems are well tested and inexpensive, we can start launching people with them.
