On August 30, 2026, NASA successfully launched the Roman Space Telescope, equipped with a 2.4-meter main mirror and an 30-million-pixel infrared camera. Its angular resolution reached 0.11 arcseconds per pixel, and its field of view was 0.28 square degrees. The telescope enables deep observations of the distant universe, focusing on dark energy, stars in the Milky Way, and exoplanets. Named after NASA’s first chief astronomer, Nancy Grace Roman, it is one of three major sky mapping projects in the United States, along with those of Epsilon and the Chilean Ruben Observatory.
NASA successfully launched the Nancy Grace Roman Space Telescope on August 30, 2026, which is now safely in orbit. Equipped with the largest infrared digital camera and a large mirror originally designed for spy satellites, the telescope features a 2.4-meter primary mirror, achieving an angular resolution of 0.11 arcseconds per pixel and a field of view of 0.28 square degrees—outperforming the Euclid satellite (1.2-meter mirror, 0.18 arcseconds, 0.57 square degrees). Its 3 million-pixel infrared camera enables frequent deep-space observations, particularly excelling at capturing infrared light redshifted due to cosmic expansion. The telescope will focus on dark energy, stars within our galaxy, and exoplanets, making it one of three major sky-mapping initiatives alongside the European Euclid mission and the Chilean Rubin Observatory, jointly driving breakthroughs in astronomy. The telescope is named in honor of NASA's first Chief Astronomer, Nancy Grace Roman.
