High performance arrays for lightweight spacecraft

Abstract

JPL is developing the solar arrays for NASA's ultralightweight spacecraft, the Lunar Get-Away Special (L-GAS), which requires 1 kWe after its slow passage through the Van Allen Belts. The solar array design developed for the mission extended recent NASA-developed photovoltain array technology to power levels well below those conventionally considered practical for deployable lightweight array technology. It has become feasible by these means to consider the design of lightweight spacecraft which require up to 3 kWe at the begining of their service life.
