Nasa’s Telescópio Espacial Nancy Grace Roman has reached completion of the final integration of its core components. Engenheiros joined the spacecraft and telescope assemblies in Voos Espaciais Goddard’s larger Centro clean room, in Greenbelt, Maryland. The stage took place on November 25, 2025.
The space agency is now preparing the observatory for final tests before sending it to Centro Espacial Kennedy, on Flórida. The launch is scheduled for early September 2026 aboard a SpaceX Falcon Heavy rocket. Esse schedule is eight months ahead of the May 2027 deadline and within budget.
Integração occurred in Centro Goddard’s clean room
Técnicos completed the joining of the two main sections of the observatory into the Greenbelt installation. The metal structure features orange solar panels and a silver base. Equipes followed the process with attention to alignment and cleaning details.

The telescope measures more than 12 meters tall in its current configuration. Ele undergoes final sensor checks and removal of components used only in testing. Most environmental checks are complete, including exposures to vibrations, extreme sounds, heat and cold.
- Painéis solar panels were inspected after minor repairs
- Antenas will undergo deployment simulations in space
- Verificações General Integration Ensures Functioning After Launch
Esses adjustments prepare the equipment for the trip to Lagrange point 2, located approximately one million kilometers from Terra.
2.4 meter Espelho expands field of view
The Roman’s primary mirror has a similar diameter to that of the Hubble, about 2.4 meters. The difference appears in the wide-field instrument, which captures images of an area of the sky at least 100 times larger than that of the Hubble at the same resolution.
The Wide Field Instrument includes a 300 megapixel camera for visible light and near infrared. Ele also features a slitless spectrometer to analyze light scattering over a wide field of view.
Essa configuration allows you to map the sky faster. What would take Hubble 2,000 years to process, Roman can accomplish in one year. The images generated will be so extensive that they will not fit on conventional screens currently available.
The observatory is expected to produce around 500 terabytes of data per year when fully operational. Para comparison, Hubble has collected approximately 400 terabytes over 35 years of activity.
Coronógrafo enables direct imaging of exoplanets
Além of the wide-field instrument, the Roman carries a coronagraph as a technology demonstration. The device blocks the glow of distant stars to record the light reflected by planets around them.
Nasa reports that the coronagraph can detect planets up to 100 million times fainter than their parent stars. Essa performance represents a 100- to 1,000-fold improvement over previous space coronagraphs.
The equipment targets planets similar to Júpiter in size, temperature and orbital distance. Direct Imagens help study atmospheres and characteristics of these bodies outside of Sistema Solar.
Missão seeks answers about dark matter and energy
The telescope will observe thousands of supernovae, some farther away than any previous record. Ele will also map billions of galaxies and chart the expansion of the universe over time.
Essas observations aim to clarify the nature of dark matter and dark energy, which together make up about 95% of the cosmos. Known normal matter alone does not explain the cohesion of galaxies or the acceleration of universal expansion.
The panoramic field of view allows you to capture transient events, such as fast radio bursts or neutron star collisions, as they occur. Cientistas hopes to record phenomena that would go unnoticed in more narrow surveys.
Próximos steps include transportation and final testing
Nasa plans to send the observatory to Centro Kennedy in mid-June. Lá final preparations for launch on the Falcon Heavy rocket will take place.
The SpaceX vehicle has already accumulated 11 missions with a 100% success rate. Após separation from the rocket, the telescope will head to point L2, where it will join other observatories such as James Webb.
Equipes continues integration checks as a complete unit. The focus is on ensuring resistance to the space environment, from launch to operation in stable orbit.
The Roman joins instruments such as the Hubble, James Webb, SPHEREx and Euclid. Cada one contributes distinct specialties in the exploration of the universe.
