Technicians have completed the construction of NASA\u2019s Nancy Grace Roman Space Telescope.<\/strong><\/h4>\nThe Roman observatory is slated to launch no later than May 2027, with the team aiming for as early as fall 2026. The mission will revolutionize our understanding of the universe with its deep, crisp, sweeping views of space.<\/p>\n
More than a thousand technicians and engineers assembled Roman from millions of individual components. Many parts were built and tested simultaneously to save time. Now that the observatory is assembled, it will undergo a spate of testing prior to shipping to NASA\u2019s Kennedy Space Center in Florida in summer 2026.<\/p>\n\n\n<\/div>
NASA\u2019s freshly assembled Nancy Grace Roman Space Telescope will revolutionize our understanding of the universe with its deep, crisp, sweeping infrared views of space. The mission will transform virtually every branch of astronomy and bring us closer to understanding the mysteries of dark energy, dark matter, and how common planets like Earth are throughout our galaxy.

The Optical Telescope Assembly is the heart of the Roman observatory. It consists of a primary mirror, which was designed and built at L3Harris Technologies in Rochester, New York, plus nine additional mirrors and supporting structures and electronics. <\/p>\n
The Roman team got a jumpstart by receiving the telescope\u2019s primary mirror<\/a><\/strong>, which will collect and focus light from cosmic objects near and far, from another government agency and then modifying it to meet NASA\u2019s needs. Using this mirror, Roman will capture stunning space vistas with a field of view at least 100 times larger than Hubble\u2019s.<\/p>\nRoman will peer through dust and across vast stretches of space and time to study the universe using infrared light, which human eyes can\u2019t see. The amount of detail these observations will reveal is directly related to the size of the telescope\u2019s mirror, since a larger surface gathers more light and measures finer features. Roman\u2019s primary mirror is 7.9 feet (2.4 meters) across, the same size as the Hubble Space Telescope\u2019s main mirror but less than one-fourth the weight (410 pounds, or 186 kilograms) thanks to major improvements in technology.<\/p>\n
