NASA’s Nancy Grace Roman Space Telescope team now is targeting as soon as early September 2026 for launch, ahead of the agency’s commitment to flight no later than May 2027.
“Roman’s accelerated development is a true success story of what we can achieve when public investment, institutional expertise, and private enterprise come together to take on the near-impossible missions that change the world,” said NASA Administrator Jared Isaacman, who announced the update at a news conference on April 21 at the agency’s Goddard Space Flight Center in Greenbelt, Maryland.
Roman will pair a large field of view with crisp infrared vision to survey deep, vast swaths of sky. While the mission was designed with dark energy, dark matter, and exoplanets in mind, Roman’s unprecedented observational capability will offer practically limitless opportunities for astronomers to explore all kinds of cosmic topics.
By the end of its five-year primary mission, Roman is expected to amass a 20,000-terabyte data archive. Scientists can draw on it to identify and study 100,000 exoplanets, hundreds of millions of galaxies, billions of stars, and rare objects and phenomena — including some that astronomers have never witnessed before.
Roman will launch on a SpaceX Falcon Heavy rocket from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. NASA and SpaceX will share more information about a specific launch date, and the agency will continue to share updates concerning prelaunch preparations as new information becomes available.
The Nancy Grace Roman Space Telescope is managed at NASA’s Goddard Space Flight Center, with participation by NASA’s Jet Propulsion Laboratory and Caltech/IPAC in Southern California, the Space Telescope Science Institute (STScI) in Baltimore, and scientists from various research institutions.

This image, released in celebration of Earth Day, shows the terminator – the line between night and day – on Earth. The Artemis II astronauts captured this view on April 2, 2026, during their journey to the Moon.
NASA science improves life on Earth every day. The agency provides insights on our home planet that can only be gathered from space to help put actionable satellite information in the hands of decision-makers. In addition, NASA’s observations of Earth and the technologies the agency develops provide the foundation needed to explore and sustain human life on the Moon, Mars, and beyond.

When NASA’s Apollo 8 crew rounded the far side of the Moon in 1968 and astronaut Bill Anders snapped a picture of Earth peeking above the gray horizon, the image became a symbol of hope in challenging times. The photograph, Earthrise, as it came to be called, helped inspire the first Earth Day celebration two years later.
This year, the astronauts of the Artemis II mission captured their own poignant images of home. The newly released photo shows Earth on April 6, as the crew traveled farther than any humans before them.
“On Earth Day, we are reminded of the extraordinary responsibility we share to understand our planet,” said NASA Administrator Jared Isaacman. “NASA’s Earth science missions continue to deliver critical data that strengthen communities, support industries like agriculture, and help the nation anticipate and respond to wildfires, droughts, flooding, and other natural hazards. Together with our Earth science partners, NASA is committed to deepening our understanding of Earth.”

From cameras pressed against spacecraft windows to the most powerful radar ever flown, imaging technology has taken giant leaps since 1968, but the drive to understand our home in the cosmos has remained.
“Our four Artemis II astronauts — Reid, Victor, Christina and Jeremy — took humanity on a journey that showed us just how special and bright our Earth is, even from the dark side of the Moon, that is especially worth celebrating on Earth Day,” said Nicky Fox, associate administrator of the Science Mission Directorate at NASA Headquarters in Washington. “Seeing the incredible images of our blue marble planet over time from Apollo 8’s Earthrise to Artemis II’s Earthset, it is not only a symbolic moment of beauty, but like the other images captured during the lunar flyby, Earthset is brimming with incredible science in high definition that will help inform our future Artemis missions on the Moon.”
Here’s a look at how NASA’s view of Earth has advanced since that early image of the planet.

In 1968, during their 120th revolution around the planet, the Apollo 7 astronauts snapped a photo of New Orleans, visible amid the green wetlands and tan sediment of the Mississippi River Delta, some 95 nautical miles below. Today, space-based radar is revealing how the earth beneath our feet is rising, sinking and sliding.
Launched in July 2025 by NASA and the Indian Space Research Organisation (ISRO), NISAR’s (NASA-ISRO Synthetic Aperture Radar) L-band and S-band SAR instruments can penetrate clouds and tree canopies to reveal details of Earth’s surface and observe changes. That’s actionable information for communities, including low-lying cities at risk of losing ground due to rising seas and subsiding land.
The NISAR mission continues a long legacy of Earth-observing satellites. Around the globe, from ice to deserts, NASA’s satellite record has chronicled changes to the human and natural world for decades. See how the recently launched PACE (Plankton, Aerosol, Cloud, and Ocean Ecosystem) satellite captured the Mississippi River Delta swirling with marine life.
“The Artemis photos shared with all of humanity the breathtaking beauty of our home planet, as it can only be seen from space,” said Karen St. Germain, division director, NASA Earth Science Division. “NASA’s fleet of Earth science satellites provide additional dimensions to this beauty, by teaching us how our planet supports the vibrant and dynamic forms of life we see on Earth. This data and discovery help us deliver actionable science so we can continue to thrive on our ever-changing planet.”
The Himalaya Mountains have captivated astronauts since the early days of the Space Age. Equipped with a handheld 70mm Hasselblad camera, L. Gordon Cooper photographed Mount Everest and its towering neighbors in 1963 while orbiting the planet 22 times alone in his Mercury-Atlas 9 capsule.
By the early 1990s, scientists were tracing the peaks and valleys of the range in spectacular detail using radar aboard the space shuttle. More recently, other space missions and instruments such as ASTER (Advanced Spaceborne Thermal Emission and Reflection Radiometer) and Landsat have aided high-altitude exploration. They’ve helped scientists pinpoint the location of a deadly avalanche on Mount Everest, and track changing plant life across some of the most remote slopes on the planet.
Liftoff of Artemis II on April 1, came exactly 66 years to the day after another milestone launch. The world’s first successful weather satellite — TIROS-1 — sported a pair of television cameras and magnetic tape machines when it rocketed into low Earth orbit in 1960. It provided weather forecasters images of cloud cover from space that improved storm forecasting.
Satellite data complemented the unique photographs captured by Apollo astronauts, who documented hurricanes, thunderheads, and other storm systems roiling beneath their feet. The work continues to this day. Next year, a new generation of radars will take flight as part of the INCUS (Investigation of Convective Updrafts) mission. The three small satellites, flying in tight formation, will help determine why, when, and where severe tropical thunderstorms, heavy precipitation, and clouds occur.
See how a water-watching satellite tracked another kind of natural hazard — a tsunami — speeding across the Pacific Ocean in the wake of a massive earthquake off Russia last July.

The images above capture two spectacular icescapes a world apart.
The snapshot on the left, taken by a crewmember on the SkyLab space station in 1974, shows plumes of brash ice near Belle Isle off Newfoundland. On the right, new sea ice forms along the coast of Antarctica in an aerial photograph taken during Operation Ice Bridge, NASA’s longest-running airborne mission to observe ice in the North and South polar regions. The findings from that mission, along with satellite laser data, have helped scientists track changes to polar ice sheets since 2003.
In the Arctic, satellites are continually observing how far sea ice retreats season by season and year over year, recording a decades-long trend of less ice cover. On the other side of the globe, in Antarctica, NASA’s MODIS (Moderate Resolution Imaging Spectroradiometer) instrument recently captured the start of summer in full color.

Picturing Earth as a blue marble tells only part of our story. Earth at night also teaches us a lot about humanity. Sensors orbiting our planet can resolve light sources down to the scale of a toll booth on a dark highway. By tracking night light illumination, scientists, policymakers and industry can map urban growth, electricity use, and economic activity across the planet.
Compare, for example, the Apollo 11 crew’s view of a shrouded Earth on the day that Neil Armstrong and Buzz Aldrin landed on the Moon in 1969, and this new data visualization based on more than 1 million satellite observations taken every night for nine years.

Beyond the border of Washington, D.C., numerous suburbs spread across Virginia and Maryland. Many are accessible from the Capital Beltway (I-495), the highway that encircles Washington. An astronaut on the International Space Station captured this photo of the beltway’s northeast side where it passes through the historic city of Greenbelt, Maryland.
The photo was taken on July 30, 2023, a time of year when the region’s vegetation is lush and green. One of the more prominent green spaces in this image is Greenbelt Park. The park’s nearly 5 square kilometers (2 square miles) contain forested hiking trails, several picnic areas, and a campground. The land was once intended as a future extension of the city of Greenbelt, but it was acquired by the National Park Service in 1950.
Just north of the park, Greenbelt’s historic district is laid out in a crescent shape. The district is one of three planned communities that arose in the 1930s as part of the New Deal program, intended to provide work for the unemployed and to create affordable cooperative housing with accessible green space. Homes connect to walking paths, which in turn connect to one of the country’s oldest planned shopping centers.
A collection of buildings east of the beltway is NASA’s Goddard Space Flight Center, established in Greenbelt on May 1, 1959, as NASA’s first spaceflight complex. Several patches of forested land separate some of the buildings. The large green spaces north of Goddard are a mix of forested land and agricultural fields in the town of Beltsville, which include University of Maryland and USDA agricultural research sites. The main campus of the University of Maryland is visible just west of Greenbelt in College Park.
Other nearby tree-lined areas are visible as well. For instance, Hyattsville, just south of College Park, has been recognized as a “tree city” for more than three decades. In addition, trees line a large segment of the Baltimore-Washington Parkway (MD-295), which runs north-south between Baltimore and Washington and bisects Greenbelt Park.
Astronaut photograph ISS069-E-39302 was acquired on July 30, 2023, with a Nikon D5 digital camera using a focal length of 1150 millimeters. It was provided by the ISS Crew Earth Observations Facility and the Earth Science and Remote Sensing Unit at NASA Johnson Space Center. The image was taken by a member of the Expedition 69 crew. The image has been cropped and enhanced to improve contrast, and lens artifacts have been removed. The International Space Station Program supports the laboratory as part of the ISS National Lab to help astronauts take pictures of Earth that will be of the greatest value to scientists and the public, and to make those images freely available on the Internet. Additional images taken by astronauts and cosmonauts can be viewed at the NASA/JSC Gateway to Astronaut Photography of Earth. Story by Kathryn Hansen.
