Now on a three-month, million-mile journey to its final orbit, NASA’s Nancy Grace Roman Space Telescope will soon reveal the universe’s darkest secrets. The mission launched at 7:26 a.m. EDT Sunday aboard a SpaceX Falcon Heavy rocket from Launch Complex 39A at the agency’s Kennedy Space Center in Florida.

Roman pairs a large field of view with crisp infrared vision to explore vast swaths of the sky and probe deeply into cosmic history. This flagship mission will help astronomers explore dark matter, dark energy, and worlds outside of our solar system, known as exoplanets. Its surveys will support a broad range of research extending far beyond the mission’s main science goals.

“Roman is exactly the kind of success story we want to see across NASA,” said NASA Administrator Jared Isaacman. “Delivered ahead of schedule and on budget, this mission reflects more than a decade of dedication from the NASA workforce and our industry partners. Now, Roman will give us a new atlas of the universe, push the boundaries of discovery, and demonstrate what is possible when America’s space program pairs bold ambition with disciplined execution.”

The ground control team at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, began receiving telemetry data from Roman seven minutes after launch. The Falcon Heavy rocket performed as expected, separating from the observatory 31 minutes into the flight. After separating from the center core, the rocket’s boosters safely returned to the launch site for refurbishment.

“Roman will be a discovery machine that will bring us closer than ever before to answering humanity’s most profound questions about our cosmic history,” said Nicky Fox, associate administrator for the Science Mission Directorate at NASA Headquarters in Washington. “With its large field of view and fast survey speeds, Roman will usher us into a new era of discovery and make the invisible visible, setting the foundation for humanity’s search for life beyond our solar system.”

During launch and early orbit, Roman uses the Near Space Network’s ground stations and relay satellites to exchange tracking, telemetry, and command data with ground controllers. About 70 minutes after launch, the Deep Space Network takes over communications and guides Roman toward the second Sun-Earth Lagrange point, or L2, about one million miles from Earth. Roman connects to that network through the Canberra Deep Space Communication Complex in Australia first. Approximately six hours later it will transfer to the Madrid Deep Space Communication Complex in Spain and then to the Goldstone Deep Space Communication Complex in California, ensuring continuous contact with Roman throughout its journey.

The Roman team also confirmed successful deployment of the observatory’s solar panels and lower instrument sun shade an hour and 23 minutes after launch. Within the upcoming days, Roman’s high-gain antenna and visor-like deployable aperture cover will deploy, ground controllers will initiate the first of two-mid-course corrections, and the Coronagraph Instrument will power on. This instrument will demonstrate the technology that future missions like NASA’s Habitable Worlds Observatory concept could use to image Earth-like planets in the search for life in the universe. Roman’s Coronagraph will take a giant step in that direction by snapping pictures of Jupiter-like planets.

A few weeks into Roman’s voyage, its primary instrument, the Wide Field Instrument, will activate. This 300-megapixel infrared camera has 18 4K detectors, each about the size of a saltine cracker. These detectors collect photons of light that will be decoded into crisp cosmic panoramas. Thanks to the observatory’s rigid design and stable optical performance, it will rapidly scan the sky without needing substantial time between separate observations. The Roman telescope is designed to survey the universe a thousand times faster than NASA’s Hubble Space Telescope.

Throughout the rest of Roman’s three-month commissioning period, scientists will run the instruments through a series of calibrations and tests. NASA anticipates releasing Roman’s first images by early 2027.

Roman will send back 1.4 terabytes of data every day, the highest data rate of any NASA astrophysics mission, so far. Machine learning, artificial intelligence, and citizen scientists will help sift through it and flag significant findings, which astronomers can then study.

“We’ve never been able to view the universe with eyes like Roman’s before,” said Julie McEnery, Roman’s senior project scientist at NASA Goddard. “There’s no telling what more we’ll know and have seen by this time next year.”

Roman is the fourth primary mission NASA has launched on a Falcon Heavy rocket. Earlier this year, the agency’s Launch Services Program worked with SpaceX to accelerate the launch date to accommodate the space telescope’s early completion.

The telescope is managed at NASA Goddard with participation by the agency’s Jet Propulsion Laboratory in Southern California; Caltech/IPAC in Pasadena, California; the Space Telescope Science Institute in Baltimore; and a team of scientists from various research institutions. The primary industrial partners are BAE Systems Inc., L3Harris Technologies, and Teledyne Scientific & Imaging. Contributions to Roman also are made by ESA, JAXA, the French space agency CNES (Centre National d’Études Spatiales), and the Max Planck Institute for Astronomy in Germany.

Eye Drops That Restore Sight? Meet the Light-Activated Molecules Giving Blind Mice Their Vision Back

For people living with blinding diseases like age-related macular degeneration or retinitis pigmentosa, the damage usually starts in one specific place: the photoreceptors, the light-detecting cells lining the retina. Once these cells degenerate, the rest of the visual system, the neurons that carry signals to the brain, is often still intact. It’s just left waiting for a signal that never arrives.

A team led by the Institute for Bioengineering of Catalonia (IBEC) in Barcelona thinks they’ve found a way to give that signal back, without touching a single gene or implanting any hardware.

The researchers developed a new family of molecules called prosthe6, built using a technique known as photopharmacology, essentially, chemistry that can be switched on and off with light. These photoswitchable compounds are designed to mimic what dying photoreceptors normally do: convert incoming light into a signal the retina’s remaining circuitry can use.

In mice that were completely blind, the results were striking. Healthy mice instinctively avoid brightly lit spaces and prefer the dark, a behavior that depends entirely on being able to see. Blind mice lose this preference completely, wandering indifferently between light and dark. After treatment with prosthe6, that instinct came back on its own, with no training involved, under everyday lighting conditions comparable to an overcast day indoors.

Two compounds in particular, prosthe6-12 and prosthe6-15, stood out, and not just for how well they worked. They restored light-driven behavior whether injected directly into the eye or simply applied as eye drops, hours after treatment, with no signs of pain, distress, or structural changes to the eye.

That detail matters enormously. Gene therapies and retinal implants, the leading experimental approaches to blindness so far, are invasive, expensive, and often limited to very specific genetic causes. A drug you could administer as eye drops would sidestep nearly all of that, at least in principle.

It’s still early-stage work, done in mice, and the compounds now need to prove themselves safe and effective for extended use before anything resembling a human trial is possible. But with an estimated 200 million people worldwide affected by photoreceptor-degenerating diseases, a spin-off company is already forming to push this technology toward the clinic.

Sometimes the most elegant solution to “the wiring still works, the sensor doesn’t” isn’t to rebuild the sensor. It’s to hand the wiring something new to listen to.
