Momentus Inc. and Ascent Solar Technologies announced a new partnership to jointly market solar arrays utilizing the low-cost Tape Spring Solar Array (TASSA) being developed by Momentus and the high performance of Ascent's flexible, lightweight photovoltaic modules. The rapid growth in the production and deployment of thousands of satellites in space has led to the burgeoning need for low-cost, reliable solar arrays with high performance. Momentus and Ascent are excited to partner to market a solar array designed to provide key advantages to customers, such as low-cost, resiliency with less degradation in the harsh environment in space, flexibility, and the ability to efficiently generate large amounts of power.

Building off the successes of the pathfinder demonstration of TASSA that was launched to Low-Earth Orbit on the Vigoride-6 mission one year ago and tested in space for several months, Momentus plans to add a high-power photovoltaic array as a differentiated feature of the next iteration of the TASSA product under development. Last year?s pathfinder TASSA demonstration validated solar blankets from Ascent Solar Technologies as a mass efficient and robust power generation solution. Momentus plans to incorporate in TASSA new higher efficiency solar blankets from ASTI composed of space industry optimized Titan Modules, providing even lower cost per kW of power.

TASSA will continue to utilize Vigoride hardware with spaceflight heritage to provide customers an entire array subsystem complete with solar array rotation actuators and controllers. This approach is oriented at streamlining mission schedules and minimizing clean room bottlenecks during spacecraft assembly integration and testing. TASSA is designed for responsive launch as well as more efficient flatpack configurations which allow for more satellites to fit within launch vehicle payload fairings.

TASSA is also retractable and re-deployable, providing a means for the minimization of cross-sectional area and array exposure if notified of potential conjunction or other orbital hazards such as space weather. This could enable TASSA to facilitate longer mission durations and increased assurance of spacecraft operations on orbit.
