NASA's Roman Space Telescope Utilizes Repurposed Spy Satellite Mirrors
NASA's Roman Space Telescope, scheduled for launch on August 30, 2026, from Kennedy Space Center, features a primary mirror originally designed for U.S. reconnaissance satellites. This mirror, donated by the National Reconnaissance Office (NRO), underscores a unique repurposing of technology initially developed for national security purposes.
The mirror, measuring 2.4 meters in diameter, matches the size of the Hubble Space Telescope's mirror but is significantly lighter, weighing only 410 pounds. This weight is less than a quarter of Hubble's mirror, reflecting advancements in material technology and design efficiency.
NASA received the mirror at its Goddard Space Flight Center on November 7, 2024, where it underwent modifications to suit the scientific objectives of the Roman Space Telescope. This telescope is expected to embark on a five-year primary mission, with the possibility of a five-year extension, focusing on astrophysical phenomena and expanding our understanding of the universe.
