NASA is planning a lunar landing near the moon’s South Pole in the 2026 time period, this mission is to be followed by the establishment of a lunar base later in the same decade. The Vertical Solar Array Technology (VSAT) project is focused on the development of solar array technologies necessary for sustained presence on the lunar surface circa 2030. Existing solar array structures and deployment system technologies are designed for either zero-g or horizontal surface deployment. VSAT will explore deployment of vertical arrays on masts of up to 10m in length in order to capture continuous sun light at the lunar south pole. The VSAT system must also be capable of stable deployment on uneven terrain and autonomous retraction to enable system mobility on the moon’s surface.

Finally, given the nature of space operations and the fuel requirements associated with a lunar landing, VSAT will be designed to be as lightweight as possible. The VSAT project objective is to engage industry in the development of the underlying technologies necessary for solar array deployments at the moon’s south pole. As part of the engagement process, the project will develop a reference mission and design to guide industry efforts. It is also expected that the project will fabricate high-risk elements of the reference design for development and test purposes. After creation of the reference missions and designs the project will solicit industry studies and analysis for the purpose of contracting with several vendors for eventual hardware development.

The VSAT project design goals are:
Vertical array deployment on extended mast in uneven terrain
Deployment mechanisms, and array system, designed for reliable, autonomous retraction and system mobility
Array system designed to be modular, adaptable to multiple mission architectures, and to minimize mass and packing volume
