Ascent Solar Technologies Inc. Achieves Spaceflight Heritage for its Space Solar PV Array Products on Momentus’ Vigoride-6 Mission

Ascent Solar Technologies (ASTI), the leading U.S. innovator in lightweight, flexible, and durable CIGS thin-film photovoltaic (PV) solutions, proudly announces its achievement of spaceflight heritage on the Momentus Vigoride-6 mission. The company’s Plug & Fly™ solar panels, integrated into Momentus’s Tape Spring Solar Array (TASSA), have successfully completed initial in-space testing, marking a significant milestone for ASTI’s space solutions.

This accomplishment not only establishes NASA Technology Readiness Level 9 (TRL9) for ASTI’s products but also validates their CIGS material, manufacturing, integration, and quality processes. Ascent’s bare PV modules have been performing as expected in the space environment, further confirming the positive results of the previous MISSE-X experiment with NASA on the ISS. This achievement reinforces the robustness of the company’s portfolio of CIGS intellectual properties for space applications.

Building on this success, Ascent Solar Technologies is now focusing on developing its next generation of higher efficiency lightweight products specifically optimized for the orbital environment. The Titan Space HDK line, derived from the subscale PV modules flown on Vigoride-6, will offer mission managers significant mass, cost, and schedule savings, with additional capacity of multiple megawatts still available for deliveries in 2024.

“This demonstration solidifies Ascent’s position as a leader in space sustainability and reflects the tremendous market opportunity we are pursuing,” states Paul Warley, CEO of Ascent Solar Technologies. “We have also demonstrated that our power generation solutions align with the European Space Agency’s Zero Debris Charter. Ascent’s Space HDK line of products are designed to withstand impacts from space debris, ensuring uninterrupted power generation without creating additional debris. This significantly reduces mission risks for spacecraft using flexible thin-film power generation capabilities like ours. These technologies will play a crucial role in preserving the increasingly crowded and trafficked global commons of Earth’s orbits.”

In line with its commitment to space sustainability, Ascent Solar Technologies continues to innovate and provide cutting-edge solutions for the industry. The company’s achievement on the Momentus Vigoride-6 mission reinforces its position as a leader in the field, paving the way for a more sustainable and debris-free space environment.
