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.
Artwork Key

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:

The award, signed by President Biden, is the highest honor the federal government can grant to a federal civilian employee.
NASA Administrator Bill Nelson and Deputy Administrator Pam Melroy presented Cabana with the award during a ceremony at NASA Headquarters in Washington on Jan. 10. Cabana most recently served as NASA’s associate administrator, which is the agency’s highest ranking civil servant, from 2021 until he retired from the agency at the end of 2023.
“A true public servant, Bob has spent his entire career in service to his country. I can think of no one more deserving of this rare honor than Bob,” said Nelson. “From his time as a naval aviator to his role as associate administrator of NASA, Bob has dedicated his life to improving his country. I join with President Biden in thanking Bob for his dedication and commitment.”
The award recognized Cabana for his roles as a Marine aviator, test pilot, astronaut and becoming the first American to enter the International Space Station. He was further recognized for continuing to push for the bounds of the possible, launching the James Webb Space Telescope, the Artemis I mission and the Orion spacecraft which will send humans back to the Moon for the first time in decades.
As a NASA astronaut, Cabana flew in space four times, including twice as commander. His final space shuttle flight in 1998 was the first International Space Station assembly mission. Cabana also was the director of the agency’s Kennedy Space Center in Florida for more than a decade. There he led its transition from retirement of the space shuttle to a multi-user spaceport once again launching NASA astronauts to low Earth orbit, and for the first time, doing so with commercial partners.
As NASA associate administrator, Cabana led the agency’s 10 center directors, as well as the mission directorate associate administrators at NASA Headquarters. He was the agency’s chief operating officer for more than 18,000 employees and oversaw an annual budget of more than $25 billion.
Cabana was selected as an astronaut candidate in June 1985 and completed training in July 1986. He logged 38 days in space during four shuttle missions. Cabana was a pilot aboard space shuttle Discovery on both the STS-41 mission in October 1990 that deployed the Ulysses spacecraft and the STS-53 mission in December 1992. He was the mission commander aboard space shuttle Columbia for the STS-65 mission in July 1994 that conducted experiments as part of the second International Microgravity Laboratory mission. He commanded space shuttle Endeavour for the STS-88 mission in December 1998.
Cabana was appointed a member of the Federal Senior Executive Service in 2000 and served in numerous senior management positions at NASA’s Johnson Space Center in Houston, ultimately becoming deputy director. He was named director of NASA’s Stennis Space Center in Mississippi in October 2007 and a year later was selected as NASA Kennedy director.
Born in Minneapolis, Cabana graduated from the U.S. Naval Academy in 1971 with a bachelor’s degree in mathematics. He became a naval aviator and graduated with distinction from the U.S. Naval Test Pilot School in 1981. In his career, Cabana logged over 7,000 hours in more than 50 different kinds of aircraft. He retired as a colonel from the U.S. Marine Corps in September 2000.
In addition to receiving the President’s Award for Distinguished Federal Service, Cabana’s accomplishments have been recognized with induction into the Astronaut Hall of Fame and being named an Associate Fellow in the American Institute of Aeronautics and Astronautics and a Fellow in the Society of Experimental Test Pilots. He has received numerous personal awards and decorations, including the Distinguished Flying Cross and the Presidential Distinguished Rank Award. He also is a recipient of the Rotary National Award for Space Achievement’s National Space Trophy.
