Should space agencies prioritize structural safety over traditional window designs in future spacecraft?
NASA engineers are moving away from traditional glass for spacecraft windows, citing structural risks during long-duration flights. The agency is now developing fully acrylic window designs to replace glass on future Orion spacecraft.
Why it matters
Glass is inherently fragile and susceptible to static fatigue, where microscopic flaws grow over time. Because glass can shatter into sharp fragments, acrylic serves as a safer alternative that also acts like a heat shield during atmospheric reentry.
Engineers at the Johnson Space Center are evaluating acrylic materials, which provide superior structural stability compared to the brittle nature of glass. While glass remains the current standard for the 7 windows found on the International Space Station's Cupola module, acrylic is being tested for its ability to resist flaw propagation.
The players
NASA
The United States government agency responsible for the nation's civilian space program and aeronautics research.
Johnson Space Center
The NASA facility in Houston that serves as the primary hub for human spaceflight training and spacecraft engineering.
The details
NASA is currently developing a fully acrylic window design for the Orion spacecraft to enhance safety across the Artemis program. This material shift aims to mitigate the risk of fragments in pressurized structures while providing the necessary durability for long-duration missions.

Deeper Dive
The transition to acrylic materials follows the engineering safety requirements established by the Artemis program. This shift marks a departure from reliance on traditional glass panels that have historically served human-rated spacecraft.
The development of more durable, acrylic-based window materials could eventually lead to safer and more robust commercial space travel options. By reducing the risks associated with glass fragmentation, this technology may lower structural failure rates for future manned missions.
The takeaway
Replacing fragile glass with stable acrylic represents a vital shift in spacecraft structural integrity for future deep-space exploration. These advancements ensure that crewed missions maintain pressurized safety standards even after extended durations in the vacuum of space.
