NASA’s Nancy Grace Roman Space Telescope is now on a three-month, million-mile journey to its final orbit, where it will investigate some of the universe’s deepest mysteries. The powerful space observatory launched at 7:26 a.m. ET on Sunday aboard a SpaceX Falcon Heavy rocket from Launch Complex 39A at NASA’s Kennedy Space Center in Florida.
Designed to survey enormous regions of the sky while capturing sharp infrared observations, the Nancy Grace Roman Space Telescope will help scientists study the universe’s history and evolution. The flagship NASA mission will investigate dark matter, dark energy, and exoplanets—worlds beyond our solar system. Its observations are also expected to support a broad range of astronomical research beyond the mission’s primary objectives.
“Roman is exactly the success story we want to see across NASA,” said NASA Administrator Jared Isaacman. “Achieved ahead of schedule and on budget, this mission reflects more than a decade of dedication by NASA employees and industry partners. Roman will now provide us with a new space atlas, push the boundaries of discovery, and demonstrate what is possible when America’s space program combines bold ambition with disciplined execution.”
The ground control team at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, began receiving Roman’s telemetry data seven minutes after liftoff. The Falcon Heavy rocket performed as expected, releasing the observatory 31 minutes into the flight. After separation from the rocket’s core, the boosters safely returned to the launch site for refurbishment.
“Roman will be a discovery machine that will bring us closer than ever before to answers to humanity’s deepest questions about the history of the universe,” said Nicky Fox, deputy administrator for NASA’s Science Mission Directorate at NASA Headquarters in Washington. “With its wide field of view and rapid research speed, Roman will lead us into a new era of discovery, making the invisible visible and laying the foundation for humanity’s search for life beyond our solar system.”
During launch and early orbit, the Roman Space Telescope will use a network of ground stations and relay satellites to exchange tracking, telemetry, and command data with mission controllers. About 70 minutes after liftoff, NASA’s Deep Space Network will assume communications and guide Roman toward the second Sun-Earth Lagrange point, or L2, approximately 1 million miles from Earth.
Roman will initially connect with the Deep Space Network through the Canberra Deep Space Communications Complex in Australia. About six hours later, communications will shift to the Madrid Deep Space Communications Complex in Spain, followed by the Goldstone Deep Space Communications Complex in California. This global network will help maintain continuous contact with the telescope throughout its journey to L2.
The mission team also confirmed the successful deployment of Roman’s solar panels and lower instrument awning one hour and 23 minutes after liftoff. In the days ahead, controllers will deploy the telescope’s high-gain antenna and visor-like aperture cover, conduct the first of two planned mid-course corrections, and power on the coronagraph instrument.
Roman’s coronagraph will demonstrate technology that could support future missions such as NASA’s Habitable Worlds Observatory, which aims to directly image Earth-like planets in the search for signs of life. As part of its technology demonstration, the coronagraph will attempt to capture an image of a Jupiter-like exoplanet.
A few weeks after launch, Roman’s primary instrument, the Wide Field Instrument, will become operational. This 300-megapixel infrared camera features 18 4K detectors, each approximately the size of a saltine cracker. The detectors collect photons of light and transform them into detailed panoramas of the cosmos.
Thanks to Roman’s stable optical performance and advanced design, the observatory will scan the sky rapidly without requiring long pauses between observations. NASA expects Roman to survey the universe up to 1,000 times faster than the Hubble Space Telescope while maintaining high-quality infrared imaging.
During the remaining three-month commissioning period, scientists and engineers will perform extensive calibrations and tests on Roman’s instruments and systems. NASA expects to release the telescope’s first images by early 2027.
Roman will transmit approximately 1.4 terabytes of data to Earth every day—the highest daily data rate of any NASA astrophysics mission to date. Machine learning tools, artificial intelligence, and citizen scientists will help analyze the data and identify potentially important discoveries for further study.
“We’ve never been able to see the universe the way Roman does before,” said Julie McEnery, Roman’s senior project scientist at NASA Goddard. “There’s no telling what more we’ll know and see by this time next year.”
The Nancy Grace Roman Space Telescope is the fourth major NASA mission launched on a SpaceX Falcon Heavy rocket. Earlier this year, NASA’s Launch Services Program worked with SpaceX to move up the launch date after the space telescope was completed ahead of schedule.
NASA Goddard manages the Roman mission, with participation from NASA’s Jet Propulsion Laboratory in Southern California, Caltech/IPAC in Pasadena, California, the Space Telescope Science Institute in Baltimore, and scientists from research institutions worldwide. Key industrial partners include BAE Systems Inc., L3Harris Technologies, and Teledyne Scientific & Imaging. Additional contributions have come from the European Space Agency, the Japan Aerospace Exploration Agency, France’s CNES space agency, and Germany’s Max Planck Institute for Astronomy.
