What is the next step in exploring the cosmos? The Nancy Grace Roman Space Telescope, NASA’s upcoming flagship mission, will take Hubble’s resolution and widen its infrared view to more than 100 times the coverage in every single image. Roman is a survey telescope that can peer through the Milky Way’s obscuring dust, and see faint, distant galaxies. Roman’s rigid design allows it to scan large regions of sky very quickly. Hubble would take 1,000 years to observe what Roman can see in one. Roman’s 18 4k x 4k detectors create 300-megapixel images covering an area of sky slightly larger than the full Moon. Roman will also look at the same regions of space repeatedly over time, allowing astronomers to see changes and observe temporary events like supernovae. Roman’s surveys of deep space and the center of our Milky Way galaxy will find thousands of new exoplanets, survey millions of galaxies, help us understand dark matter and dark energy, and learn more about the evolution of the universe. || ", "hits": 369 }, { "id": 14887, "url": "https://svs.gsfc.nasa.gov/14887/", "result_type": "Produced Video", "release_date": "2025-09-18T11:00:00-04:00", "title": "NASA Mission to Study Giant ‘Halo’ Surrounding Earth", "description": "In 1972, Apollo 16 astronauts placed an ultraviolet camera on the Moon that captured the first images of Earth’s geocorona, the light emitted by Earth’s outermost atmospheric layer.

Each side of the triangular array will measure nearly 1.6 million miles, or 2.5 million kilometers.Twin telescopes aboard each spacecraft will both transmit and receive infrared laser beams to track their companions, and NASA is supplying all six of them to the LISA mission. The prototype, called the Engineering Development Unit Telescope, will provide guidance as engineers and scientists work toward building the flight hardware.In May, the prototype, which was manufactured and assembled by L3Harris Technologies in Rochester, New York, arrived at NASA's Goddard Space Flight Center in Greenbelt, Maryland. The primary mirror is coated in gold to better reflect the infrared lasers and to reduce heat loss from a surface exposed to cold space since the telescope will operate best when close to room temperature. The prototype is made entirely from an amber-colored glass-ceramic called Zerodur, manufactured by Schott in Mainz, Germany. The material is widely used for telescope mirrors and other applications requiring high precision because its shape changes very little over a wide range of temperatures. || ", "hits": 111 }, { "id": 14575, "url": "https://svs.gsfc.nasa.gov/14575/", "result_type": "Produced Video", "release_date": "2024-04-26T13:30:00-04:00", "title": "Moving Roman - Propulsion", "description": "Moving Roman: Propulsion.

The room is a class 10,000 clean room with over one million cubic feet of space.The outside half of Roman, called OSD, contains the solar panels and protective layers. The Deployable Aperture Cover, which protects the mirrors during launch and then unfolds to help shield them from sunlight does a test deployment. During this test, lines connect to it and pull upward to negate Earth’s gravitational forces, which Roman will not experience in space. Then the Solar Array Sun Shield panels deploy. There are four panels that move. They fold against the spacecraft to fit inside the rocket fairing and then deploy in space to make a large flat plane that both collects light to generate electricity and helps keep the rest of Roman cool.In preparation for additional testing, technicians put a clean tent over OSD and transport it out of the clean room. They push it into the acoustic test chamber where a six-foot-tall horn projects up to 150-decibel sound at varying frequencies. The other tests are on two vibration tables that shake Roman along all three axes: up/down, left/right, and forward/backward. Engineers attach hundreds of sensors and run tests of increasing intensity. During and after each test, they carefully study the data to make sure that Roman is behaving as they anticipated.While these tests occur, Roman’s inside half, containing the mirrors, instruments and support equipment, move into Goddard’s largest thermal vacuum chamber, the SES (Space Environment Simulator). This 40-foot-tall chamber can simulate the vacuum of space and the wide temperature range that Roman will experience there: from -310° Fahrenheit (-190° C) to 302° Fahrenheit (150° C). The move to the chamber happens without a clean tent, so the entire path was cleaned, and all the workers dress in full clean-room garb to ensure that no dirt contaminates the sensitive parts of the spacecraft. Once the two layers of doors are sealed, Roman spends 72 days inside running through tests at various temperatures and with equipment turned on to ensure that it works at low temperature in a vacuum. A special array installed above the mirror projects light that engineers use to test the optics and sensors.After leaving the SES chamber and returning to the SSDIF, Roman’s primary and secondary mirrors are carefully cleaned and inspected. It is a balance to get the mirrors as clean as possible while not cleaning too aggressively and damaging the delicate surfaces. The mirrors are cleaned both horizontally with a gentle vacuum cleaner and vertically with brushes. After this cleaning, every inch is visually inspected and photographed to record the exact optical characteristics. This was the last time the primary mirror would be accessible.Finally, in late November, Roman’s two halves are joined together to form the complete observatory. The process takes the better part of a day. Two guide poles are installed on the inside half to help direct OSD down onto it. At various times, the clearances between the two halves are only a few inches. With the observatory complete, it begins preparing for another round of deployments and testing.Music credit: “Our Journey Begins,” Dan Thiessen [BMI], Universal Production MusicWatch this video on the NASA Goddard YouTube channel.Complete transcript available. || YTframe_Roman_Hardware_Highlights_SummerFall2025_3.jpg (1280x720) [473.7 KB] || Roman_HH_Summer-Fall2025_10mbps.mp4 (1920x1080) [185.0 MB] || Roman_HH_Summer-Fall2025_25mbps.mp4 (1920x1080) [452.7 MB] || Roman_HH_Summer-Fall2025_YT.mp4 (1920x1080) [880.2 MB] || RomanHHLate2025Captions.en_US.srt [588 bytes] || RomanHHLate2025Captions.en_US.vtt [570 bytes] || Roman_HH_Summer-Fall2025_ProRes_1920x1080_2997.mov (1920x1080) [2.5 GB] || ", "hits": 240 }, { "id": 14472, "url": "https://svs.gsfc.nasa.gov/14472/", "result_type": "Produced Video", "release_date": "2023-11-27T00:00:00-05:00", "title": "360 Video of NASA's Webb Telescope at NASA's Goddard Space Flight Center", "description": "This 360 video was taken before NASA's James Webb Space Telescope left NASA's Goddard Space Flight Center in Greenbelt, Maryland, in May 2017.
