On July 18, 1996, the United States and Israel entered into an agreement to produce a cooperative (THEL), called the Advanced Concept Technology Demonstrator, which would utilize technologies. THEL conducted test firing in FY1998, and (IOC) was planned in FY1999. However, this was signific.
[pdf] For future missions, it is desirable to reduce solar array mass, and to increase the power generated per unit area. This will reduce overall spacecraft mass, and may make the operation of solar-powered spacecraft feasible at larger distances from the sun. Solar array mass could be reduced with thin-film photovoltaic cells, flexible blanket substrates, and composite support structures. Solar array efficiency could be improved by using new photovoltaic cell materials an.
