# Nancy Grace Roman Space Telescope launched and instrumented > Live situation record from CLSTR: https://clstr.news/situations/nasas-roman-space-telescope-moves-toward-launch-and-outlines-key-scientific-objectives > Updated: 2026-09-08T14:00:00.000Z. Sources: 311. Developments: 31. NASA successfully launched the Nancy Grace Roman Space Telescope on Sunday, August 30, 2026, from Kennedy Space Center’s Launch Complex 39A in Florida. Carried into orbit by a SpaceX Falcon Heavy rocket, the observatory is on a roughly 100-day transit to the second Sun-Earth Lagrange point (L2), located approximately 1.5 to 1.6 million kilometers from Earth. The mission, with a lifecycle cost of approximately $4.316 billion, aims to investigate dark energy, dark matter, and the accelerating expansion of the universe. It is designed to work alongside observatories like the James Webb Space Telescope and the Euclid mission to provide a comprehensive understanding of cosmic evolution. The telescope features a 2.4-meter primary mirror, similar in size to the Hubble Space Telescope, but utilizes a Wide Field Instrument that provides a field of view at least 100 times larger than Hubble’s, allowing for significantly faster sky surveys. On September 1, 2026, the mission reached a significant milestone with the successful activation of its Coronagraph Instrument. This system uses advanced optics and masks to block starlight, allowing for the direct imaging of planets and dusty disks around nearby stars. Following its separation from the launch vehicle, the telescope is undergoing a critical checkout phase to test the complete system chain in space, including instrument focus, image sharpness, data rates, and the deployment of solar shields and communication components. NASA expects to release the first major scientific infrared images from the mission in early 2027, following a multi-month commissioning and calibration phase. ## Claims - The observatory cost $4.3 billion.
