Watch NASA’s Roman Space Telescope Launch Live Aug. 30: The Infrared Mission Set to Map Billions of Galaxies

NASA Kennedy Space Center, Florida, Source :. The countdown to a new era of infrared astronomy is officially underway. NASA’s Nancy Grace Roman Space Telescope is getting ready to lift off from Florida, and the agency has laid out all the ways you can follow along. Launch is targeted for no earlier than 7:26 a.m. EDT on Sunday, Aug. 30, 2026, from Launch Complex 39A at NASA’s Kennedy Space Center. A SpaceX Falcon Heavy rocket will carry the observatory into orbit, and live coverage begins at 6:20 a.m. EDT.

Roman is named after NASA’s first chief astronomer, and its mission is one of the most ambitious in modern space science. The telescope combines sharp infrared vision with a field of view at least 100 times larger than Hubble’s. That means it can capture vast sections of the sky quickly while still zooming in on faint cosmic objects. The result is an observatory built for discovery. What exactly is dark energy? How are galaxies shaped over time? Where do exoplanets form? Roman is designed to search for answers.

The mission’s science goals are broad. It will map billions of galaxies, probe the nature of dark matter, discover and characterize exoplanets, and study black holes. It will also look at objects ranging from our solar system to the edge of the observable universe. In other words, Roman is a cosmic explorer with a very detailed travel itinerary.

Two powerful instruments make this possible. The Wide Field Instrument is designed for large sky surveys, capturing enormous cosmic scenes in one shot. The Coronagraph Instrument blocks light from bright stars, which lets scientists directly image planets orbiting those stars. This opens a window onto exoplanet atmospheres and brings us closer to understanding what conditions might support life elsewhere. Roman will offer this kind of detail for a wide range of worlds, and that could change the search for life beyond Earth.

After separating from the Falcon Heavy, Roman will travel to the second Sun-Earth Lagrange point, known as L2, roughly one million miles from Earth. From that stable perch, it will observe the universe in infrared light. The mission has a five-year primary lifetime and a goal of operating for ten years. And the science data it collects will be processed and made publicly available, so the discoveries will be shared with everyone.

The launch experience actually starts a day early. On Saturday, Aug. 29, NASA kicks off with a mission science briefing at 9 a.m. EDT, followed by a prelaunch news conference at 10:30 a.m. EDT. NASA Administrator Jared Isaacman is expected to fly by the rocket and telescope at the pad at 11:45 a.m., and in-person media interviews start at noon. Then Sunday, Aug. 30, is the main event. Launch coverage begins at 6:20 a.m. EDT, liftoff happens at 7:26 a.m., and a postlaunch news conference is scheduled for 9:30 a.m. You can tune in to audio-only coverage on NASA’s broadcast circuits, or watch the livestream on NASA’s website. Blog updates, photos, and a virtual guest program make it easy to experience the launch from anywhere.

The Roman Space Telescope is managed by NASA’s Goddard Space Flight Center, with key involvement from NASA’s Jet Propulsion Laboratory, Caltech/IPAC, and the Space Telescope Science Institute. The industrial team includes BAE Systems, L3Harris Technologies, and Teledyne Scientific & Imaging. International collaboration comes from ESA, JAXA, the French space agency CNES, and the Max Planck Institute for Astronomy in Germany. NASA’s Launch Services Program, based at Kennedy, manages the launch service. This mission really is a world effort.

With its unprecedented view of the infrared universe, Roman is expected to reshape our understanding of cosmic expansion, galaxy formation, exoplanetary systems, and dark matter. As launch day approaches, the excitement on Florida’s Space Coast continues to build. This time next year, we'll have a whole new collection of cosmic questions to explore. And it all starts with that morning launch from Launch Complex 39A. Be sure to mark your calendar.
