      NASA’s Roman Coronagraph Instrument will greatly advance our ability to directly image exoplanets, or planets and disks around other stars.
      The Roman Coronagraph Instrument, a technology demonstration designed and built by NASA’s Jet Propulsion Laboratory, will fly aboard NASA’s next flagship astrophysics observatory, the Nancy Grace Roman Space Telescope.
      Coronagraphs work by blocking light from a bright object, like a star, so that the observer can more easily see a nearby faint object, like a planet. The Roman Coronagraph Instrument will use a unique suite of technologies including deformable mirrors, masks, high-precision cameras, and active wavefront sensing and control to detect planets 100 million times fainter than their stars, or 100 to 1,000 times better than existing space-based coronagraphs. The Roman Coronagraph will be capable of directly imaging reflected starlight from a planet akin to Jupiter in size, temperature, and distance from its parent star.

      The Wide-Field Instrument (WFI), the primary instrument aboard NASA’s Nancy Grace Roman Space Telescope, is a 300-megapixel visible and infrared camera that will allow scientists to perform revolutionary astrophysics surveys.  
      This specialized camera detects faint light across the cosmos and will be used to study a wide range of astrophysics topics including the expansion and acceleration of our universe, planets orbiting other stars in the Milky Way, and far off galaxies.
      WFI will conduct surveys to detect and measure billions of stars and galaxies along with rare phenomena that would otherwise be difficult or impossible to find. To survey large areas of sky, WFI uses a suite of 18 detectors that convert incoming light into electrical signals that are translated into images.
      While Roman will operate alongside other space telescopes like Hubble, WFI’s capabilities are pushing the boundaries of what is possible. Roman’s WFI has a similar sensitivity and resolution to Hubble, but WFI will capture images that cover about 100 times more sky in a single observation and will survey the sky up to 1,000 times faster.

      1. The Nancy Grace Roman Space Telescope
      2. Light Path : The light entering the telescope will take this path, bouncing off of multiple focusing mirrors and passing through filters or dispersers in the element wheel to reach the detectors.
      3. Important Years : 1990: NASA’s Hubble Space Telescope launched. 1960: Nancy Grace Roman became NASA’s Chief Astronomer.
      4. Field of View : Roman’s field of view is about 100 times larger than that of the infrared camera onboard the Hubble Space Telescope. WFI’s large field of view is achieved using an array of 18 detectors which are represented by the squares in this graphic
      5. Detectors : This dial has one tick mark for each of WFI’s 18 detectors.
      6. Modes : WFI has imaging and spectroscopy modes.
      7. Wavelengths : WFI will observe in both visible and infrared light and can select which wavelengths    reach the detectors using filters in the element wheel.
      8. “Dark Energy” Drink + “Dark Matter” Candy : Roman will enable new research into the mysteries of dark energy and dark matter.  
      9. Science Goals : The names of these games capture WFI’s role as a survey instrument and the types of surveys it will perform.
      10. Joystick : This joystick features design elements found on the WFI’s element wheel assembly, a large, rotating metal disk with optics that filter or disperse light.

      NASA Deputy Administrator Pam Melroy gives keynote remarks during the 37th Space Symposium, Tuesday, April 5, 2022, in Colorado Springs, Colorado. Photo Credit: (NASA/Bill Ingalls) The Rotary National Award for Space Achievement Foundation has selected NASA Deputy Administrator Pam Melroy, a retired United States Air Force colonel and former NASA astronaut, to receive the 2025 National Space Trophy on April 25 in Houston.
      “This honor is not just a reflection of my journey but a testament to the incredible teams and visionaries I’ve been privileged to work alongside,” said Melroy. “Exploring space is the ultimate act of human aspiration, proving time and again that when we dream together, we achieve the impossible. Being selected for the National Space Trophy is a humbling reminder of how far we’ve come — and how much further we can go.”
      Vanessa Wyche, director of NASA’s Johnson Space Center in Houston, who nominated Melroy alongside former NASA Johnson director Michael Coats, said, “Pam has brilliantly paved the way for future generations pursuing careers in STEM fields through her exemplary leadership, dedication to mission excellence, and integral contributions to the advancement of space exploration. I am thrilled and immensely proud that Pam is receiving this well-deserved recognition.”
      Sworn in as NASA’s deputy administrator on June 21, 2021, Melroy assists NASA Administrator Bill Nelson on key agency decisions, defines the agency’s strategic vision, and represents NASA to key government and international partners.
      Melroy first joined NASA as an astronaut in 1994 and holds the distinction of being only one of two women to command a space shuttle. She spent more than 38 days in space across three space shuttle missions, all contributing to the assembly of the International Space Station. She served as pilot for STS-92 in 2000 and STS-112 in 2002, and she commanded STS-120 in 2007.
      After serving more than two decades in the U.S. Air Force and as a NASA astronaut, Melroy transitioned to leadership roles at Lockheed Martin, the Federal Aviation Administration, the Defense Advanced Research Projects Agency, and Nova Systems Pty, Australia. Additionally, she was as an advisor to the Australian Space Agency and a member of the National Space Council’s Users Advisory Group.
      The Rotary National Award for Space Achievement Foundation invites members of the public and the aerospace community to attend the Space Awards gala where Melroy will be recognized with the National Space Trophy. For more information on Melroy, visit:

      First NASA Neurodiversity Network Intern to Present at the American Geophysical Union Annual Conference
      The NASA Science Activation Program’s NASA’s Neurodiversity Network (N3) project sponsors a summer internship program for high school students, in which learners on the autism spectrum are matched with NASA Subject Matter Experts. N3 intern Lillian Hall and mentor Dr. Juan Carlos Martinez Oliveros presented Lilly’s summer research project on December 9 at the 2024 American Geophysical Union conference in Washington, D.C. Their poster, entitled “Eclipse Megamovie: Image Processing”, represents the first time an N3 intern has co-authored a presentation at the prestigious AGU conference.
      The NASA Citizen Science project, Eclipse Megamovie, is leveraging the power of citizen science to construct a high-resolution time-lapse of the Sun’s corona during the April 8, 2024 total solar eclipse. By coordinating the work of hundreds of participants along the path of totality, a substantial dataset of images was obtained. The goal of the project is to unveil dynamic transformations in the Sun’s atmosphere that are only visible during a total solar eclipse.
      To process the vast quantity of imaging data collected, Lilly assisted Dr. Martinez Oliveros and other researchers in implementing a robust pipeline involving image calibration, registration, and co-location. Image registration techniques aligned the solar features across different frames, compensating for Earth’s rotation and camera movement. Finally, they used imaging techniques to enhance the signal-to-noise ratio, revealing subtle coronal structures and possible dynamics. This comprehensive data processing methodology has enabled the extraction of meaningful scientific information from the Eclipse Megamovie dataset.
      Here’s what Lilly had to say: “Working with N3 has given me a chance to use my neurodiverse perspective to make an impact on NASA research. Through the processes of my project and the opportunity to share it at the American Geophysical Union conference, I am so grateful to have found my spot in the planetary science field I dream to continue researching in the future.”
