The voyages of the Starship Enterprise came to a sudden and premature end on June 3, 1969, with the airing of the final episode of the Star Trek original television series. Ironically, the show’s cancellation came just six weeks before humanity embarked on its first voyage to land on another celestial body. Although the show ran for only three seasons, it generated a devoted fan base disappointed by the cancellation despite their write-in campaign to keep it on the air. But as things turned out, over the decades Star Trek evolved into a global phenomenon, first with the original episodes replayed in syndication, followed by a series of full-length motion pictures, and eventually a multitude of spin-off series. With its primary focus on space exploration, along with themes of diversity, inclusion, and innovation, the Star Trek fictional universe formed a natural association with NASA’s real life activities.

Star Trek creator Gene Roddenberry first had the idea for a science fiction television series in 1964. He presented his idea, a show set in the 23rd century aboard a starship with a crew dedicated to exploring the galaxy, to Desilu Productions, an independent television production company headed by Lucille Ball. They produced a pilot titled “The Cage,” selling it to the National Broadcasting Corporation (NBC) network that then bought a second pilot titled “Where No Man Has Gone Before.” NBC introduced the show to its fall 1966 lineup, with the first episode “The Man Trap” airing on Sep. 8. To put that date in perspective, NASA launched Gemini XI four days later, one of the missions that helped the agency achieve the Moon landing nearly three years later. Meanwhile, Star Trek’s Starship Enterprise continued its fictional five-year mission through the galaxy to “seek out new life and new civilizations.” The makeup of the Enterprise’s crew made the show particularly attractive to late 1960s television audiences. The major characters included an African American woman communications officer, an Asian American helmsman, and a half-human half-Vulcan science officer, later joined by a Russian-born ensign. While the show enjoyed good ratings during its first two seasons, cuts to its production budget resulted in lower quality episodes during its third season leading to lower ratings and, despite a concerted letter-writing campaign from its dedicated fans, eventual cancellation.

Despite the show’s cancellation, Star Trek lived on and prospered in syndication and attracted an ever-growing fan base, turning into a worldwide sensation. Often dubbed “trekkies,” these fans held the first of many Star Trek conventions in 1972. When in 1976 NASA announced that it would name its first space shuttle orbiter Constitution, in honor of its unveiling on the anniversary of the U. S. Constitution’s ratification, trekkies engaged in a dedicated letter writing campaign to have the orbiter named Enterprise, after the starship in the television series. This time the fans’ letter writing campaign succeeded. President Gerald R. Ford agreed with the trekkies and directed NASA to rechristen the first space shuttle. When on Sept. 17, 1976, it rolled out of its manufacturing plant in Palmdale, California, appropriately accompanied by a band playing the show’s theme song, it bore the name Enterprise. Many of the original cast members of the show as well as its creator Rodenberry participated in the rollout ceremony, hosted by NASA Administrator James C. Fletcher. Thus began a lengthy relationship between the space agency and the Star Trek brand.

During the development of the space shuttle in the 1970s, the need arose to recruit a new group of astronauts to fly the vehicle, deploy the satellites, and perform the science experiments. When NASA released the call for the new astronaut selection on July 8, 1976, it specifically encouraged women and minorities to apply. To encourage those applicants, NASA chose Nichelle Nichols, who played communications officer Lt. Uhura on the Starship Enterprise, to record a recruiting video and speak to audiences nationwide. She came to NASA’s Johnson Space Center (JSC) in Houston in March 1977, and accompanied by Apollo 12 and Skylab 3 astronaut Alan L. Bean, toured the center and filmed scenes for the video in Mission Control and other facilities. NASA hoped that her stature and popularity would encourage women and minorities to apply, and indeed they did. In January 1978, when NASA announced the selection of 35 new astronauts from more than 8,000 applicants, for the first time the astronaut class included women and minorities. All distinguished themselves as NASA astronauts and paved the way for others in subsequent astronaut selections. Nichols returned to JSC in September 2010 with the Traveling Space Museum, an organization that partners with schools to promote space studies. She toured Mission Control and the International Space Station trainer accompanied by NASA astronaut B. Alvin Drew. She also flew aboard NASA’s Stratospheric Observatory for Infrared Astronomy (SOFIA) airborne telescope aircraft managed by NASA’s Ames Research Center in Silicon Valley, California, in September 2015.

Meanwhile, the Star Trek brand renewed itself in 1979 as a full-length motion picture with the original TV series cast members reprising their roles. Over the years, several sequels followed this first film. And on the small screen, a reboot of sorts occurred in 1987 with the premiere of Star Trek: The Next Generation, a new series set in the 24th century aboard the Enterprise-D, a next generation starship with a new crew. That series lasted seven seasons, followed by a near-bewildering array of spin-off series, all built on the Star Trek brand, that continue to this day.

James Doohan, the actor who played Lt. Cmdr. Montgomery “Scotty” Scott, the Starship Enterprise’s chief engineer, had early associations with NASA. In April 1967, Doohan visited NASA’s Dryden (now Armstrong) Flight Research Center in California, spending time with NASA test pilot Bruce A. Peterson. A month later, Peterson barely survived a horrific crash of the experimental M2-F2 lifting body aircraft. He inspired the 1970s TV series The Six-Million Dollar Man, and the show’s opening credits include film of the crash. Doohan narrated a documentary film about the space shuttle released shortly before Columbia made its first flight in April 1981. In January 1991, Doohan visited JSC and with NASA astronaut Mario Runco (who sometimes went by the nickname “Spock”) toured the shuttle trainers, Mission Control, and tried his hand at operating the shuttle’s robotic arm in the Manipulator Development Facility. In a unique tribute, astronaut Neil A. Armstrong, the first person to step on the lunar surface, spoke at Doohan’s retirement in 2004, addressing him as “one old engineer to another.”

George Takei, who played Enterprise helmsman Lt. Hikaru Sulu, and his husband Brad, visited JSC in May 2012. Invited by both Asian American and LGBTQ+ Employee Resource Groups, Takei spoke of leadership and inclusiveness, including overcoming challenges while in Japanese American internment camps during World War II and as a member of the LGBTQ+ community. He noted that Star Trek remained ahead of its time in creating a future when all members of society could equally participate in great undertakings, at a time when the country struggled through the Civil Rights movement and the conflict in Southeast Asia. The inclusiveness that is part of NASA’s culture greatly inspired him. JSC Director Michael L. Coats presented Takei with a plaque including a U.S. flag flown aboard space shuttle Atlantis’ STS-135 mission. He also visited Mission Control and spent some time with Robonaut.

Leonard Nimoy played the science officer aboard the Starship Enterprise, the half-human, half-Vulcan Mr. Spock. The actor watched in September 2012 when space shuttle Enterprise arrived at John F. Kennedy International Airport in New York, on the last leg of its journey to the Intrepid Sea, Air and Space Museum, where it currently resides. “This is a reunion for me,” observed Nimoy. “Thirty-five years ago, I met the Enterprise for the first time.” As noted earlier, the Star Trek cast attended the first space shuttle’s rollout in 1976. Following his death in 2015, European Space Agency astronaut Samantha Cristoforetti paid tribute to Nimoy aboard the International Space Station by wearing a Star Trek science officer uniform, giving the Vulcan greeting, and proclaiming, “Of all the souls I have encountered … his was the most human.”

Captain James T. Kirk, played by actor William Shatner, a life-long advocate of science and space exploration, served at the helm of the Starship Enterprise. His relationship with NASA began during the original series, with references to the space agency incorporated into several story lines. In 2011, Shatner hosted and narrated a NASA documentary celebrating the 30th anniversary of the Space Shuttle program, and gave his time and voice to other NASA documentaries. NASA recognized Shatner’s contributions in 2014 with a Distinguished Public Service Medal, the highest award NASA bestows on non-government individuals. NASA Deputy Associate Administrator for Communications Robert “Bob” N. Jacobs presented the medal to Shatner. The award’s citation read, “For outstanding generosity and dedication to inspiring new generations of explorers around the world, and for unwavering support for NASA and its missions of discovery.” In 2019, Shatner narrated the NASA video We Are Going, about NASA’s plans to return astronauts to the Moon. He has spoken at numerous NASA-themed events and moderated panels about NASA’s future plans. On Oct. 13, 2021, at the age of 90, Shatner reached the edge of space during the NS-18 suborbital flight of Blue Origin’s New Shepard vehicle, experiencing three minutes of weightlessness.

Elements of the Star Trek universe have made their way not only into popular culture but also into NASA culture. As noted above, Star Trek fans had a hand in naming the first space shuttle Enterprise. NASA’s Earth observation facility aboard the space station that makes use of its optical quality window bears the name the Window Observational Research Facility (WORF). The connection between that acronym and the name of a Klingon officer aboard the Enterprise in the Star Trek: The Next Generation TV series seemed like an opportunity not to be missed – the facility’s official patch bears its name in English and in Klingon. Several astronaut crews have embraced Star Trek themes for their unofficial photographs. The STS-54 crew dressed in the uniforms of Starship Enterprise officers from Star Trek II: The Wrath of Kahn, the second full-length feature motion picture of the series. Space shuttle and space station crews created Space Flight Awareness (SFA) posters for their missions, and more than one embraced Star Trek themes. The Expedition 21 crew dressed in uniforms from the original series, while the STS-134 crew chose as their motif the 2009 reboot motion picture Star Trek.

As much as Star Trek has influenced NASA, in turn the agency has left its mark on the franchise, from episodes referencing actual and future spaceflight events to NASA astronauts making cameo appearances on the show. The first-season episode “Court Martial” that aired in February 1967 featured a photograph of the December 1965 Gemini VI launch adorning a wall aboard a star base. In the second-season episode “Return to Tomorrow,” airing in February 1968, Captain Kirk in a dialogue about risk-taking remarks, “Do you wish that the first Apollo mission hadn’t reached the Moon?” a prescient reference to the first Apollo mission to reach the Moon more than 10 months after the episode aired. Astronaut Mae C. Jemison, who credits Nichelle Nichols as her inspiration to become an astronaut, appeared in the 1993 episode “Second Chances” of Star Trek: The Next Generation, eight months after her actual spaceflight aboard space shuttle Endeavour. In May 2005, two other NASA astronauts, Terry W. Virts and E. Michael Fincke, appeared in “These are the Voyages…,” the final episode of the series Star Trek: Enterprise.

In the 2016 documentary “NASA on the Edge of Forever: Science in Space,” host NASA astronaut Victor J. Glover states, “Science and Star Trek go hand-in-hand.” The film explores how for 50 years, Star Trek influenced scientists, engineers, and even astronauts to reach beyond their potential. While the space station doesn’t speed through the galaxy like the Starship Enterprise, much of the research conducted aboard the orbiting facility can make the fiction of Star Trek come a little closer to reality. Several of the cast members from the original TV series share their viewpoints in the documentary, along with those of NASA managers and scientists. Over the years, NASA has created several videos highlighting the relationship between the agency and the Star Trek franchise. In 2016, NASA Administrator Charles F. Bolden led a video tribute to celebrate the 50th anniversary of the first Star Trek episode.

In a tribute to Star Trek creator Gene Roddenberry on the 100th anniversary of his birth, his son Rod, upper left, hosts a virtual panel discussion about diversity and inspiration.

In 2021, on the 100th anniversary of Gene Roddenberry’s birth, his son Rod hosted a virtual panel discussion, introduced by NASA Administrator C. William “Bill” Nelson, about diversity and inspiration, two ideals the Star Trek creator infused into the series. Panelists included Star Trek actor Takei, Tracy D. Drain, flight systems engineer for the Europa Clipper spacecraft at NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California, NASA astronaut Jonny Kim, Swati Mohan, guidance and operations lead for the Mars 2020 rover at JPL, and Hortense B. Diggs, Director of the Office of Communication and Public Engagement at NASA’s Kennedy Space Center in Florida.

The mutual attraction between NASA and Star Trek stems from, to paraphrase the opening voiceover from the TV series, that both seek to explore and discover new worlds, and to boldly go where no one has gone before. The diversity, inclusion, and inspiration involved in these endeavors ensure that they will live long and prosper.

      Preparations for Next Moonwalk Simulations Underway (and Underwater)
      NASA’s Perseverance Mars rover used its right-front navigation camera to capture this first view over the rim of Jezero Crater on Dec. 10, 2024, the 1,354th Martian day, or sol, of the mission. The camera is facing west from a location nicknamed “Lookout Hill.”NASA/JPL-Caltech NASA’s Perseverance Mars rover captured this scene showing the slippery terrain that’s made its climb up to the rim of Jezero Crater challenging. Rover tracks can be seen trailing off into the distance, back toward the crater’s floor.NASA/JPL-Caltech The road ahead will be even more scientifically intriguing, and probably somewhat easier-going, now that the six-wheeler has completed its long climb to the top.
      NASA’s Perseverance Mars rover has crested the top of Jezero Crater’s rim at a location the science team calls “Lookout Hill” and rolling toward its first science stop after the monthslong climb. The rover made the ascent in order to explore a region of Mars unlike anywhere it has investigated before.
      Taking about 3½ months and ascending 1,640 vertical feet (500 vertical meters), the rover climbed 20% grades, making stops along the way for science observations. Perseverance’s science team shared some of their work and future plans at a media briefing held Thursday, Dec. 12, in Washington at the American Geophysical Union’s annual meeting, the country’s largest gathering of Earth and space scientists.
      “During the Jezero Crater rim climb, our rover drivers have done an amazing job negotiating some of the toughest terrain we’ve encountered since landing,” said Steven Lee, deputy project manager for Perseverance at NASA’s Jet Propulsion Laboratory in Southern California. “They developed innovative approaches to overcome these challenges — even tried driving backward to see if it would help — and the rover has come through it all like a champ. Perseverance is ‘go’ for everything the science team wants to throw at it during this next science campaign.”
      A scan across a panorama captured by NASA’s Perseverance Mars rover shows the steepness of the terrain leading to the rim of Jezero Crater. The rover’s Mastcam-Z camera system took the images that make up this view on Dec. 5. NASA/JPL-Caltech/ASU/MSSS Since landing at Jezero in February 2021, Perseverance has completed four science campaigns: the “Crater Floor,” “Fan Front,” “Upper Fan,” and “Margin Unit.” The science team is calling Perseverance’s fifth campaign the “Northern Rim” because its route covers the northern part of the southwestern section of Jezero’s rim. Over the first year of the Northern Rim campaign, the rover is expected to visit as many as four sites of geologic interest, take several samples, and drive about 4 miles (6.4 kilometers).
      “The Northern Rim campaign brings us completely new scientific riches as Perseverance roves into fundamentally new geology,” said Ken Farley, project scientist for Perseverance at Caltech in Pasadena. “It marks our transition from rocks that partially filled Jezero Crater when it was formed by a massive impact about 3.9 billion years ago to rocks from deep down inside Mars that were thrown upward to form the crater rim after impact.”
      This animation shows the position of NASA’s Perseverance Mars rover as of Dec. 4, 2024, the 1,347th Martian day, or sol, of the mission, along with the proposed route of the mission’s fifth science campaign, dubbed Northern Rim, over the next several years. NASA/JPL-Caltech/ESA/University of Arizona “These rocks represent pieces of early Martian crust and are among the oldest rocks found anywhere in the solar system. Investigating them could help us understand what Mars — and our own planet — may have looked like in the beginning,” Farley added.
      First Stop: ‘Witch Hazel Hill’
      With Lookout Hill in its rearview mirror, Perseverance is headed to a scientifically significant rocky outcrop about 1,500 feet (450 meters) down the other side of the rim that the science team calls “Witch Hazel Hill.”
      “The campaign starts off with a bang because Witch Hazel Hill represents over 330 feet of layered outcrop, where each layer is like a page in the book of Martian history. As we drive down the hill, we will be going back in time, investigating the ancient environments of Mars recorded in the crater rim,” said Candice Bedford, a Perseverance scientist from Purdue University in West Layfette, Indiana. “Then, after a steep descent, we take our first turns of the wheel away from the crater rim toward ‘Lac de Charmes,’ about 2 miles south.”
      Lac de Charmes intrigues the science team because, being located on the plains beyond the rim, it is less likely to have been significantly affected by the formation of Jezero Crater.
      After leaving Lac de Charmes, the rover will traverse about a mile (1.6 kilometers) back to the rim to investigate a stunning outcrop of large blocks known as megabreccia. These blocks may represent ancient bedrock broken up during the Isidis impact, a planet-altering event that likely excavated deep into the Martian crust as it created an impact basin some 745 miles (1,200 kilometers) wide, 3.9 billion years in the past.
      More About Perseverance
      A key objective of Perseverance’s mission on Mars is astrobiology, including caching samples that may contain signs of ancient microbial life. The rover will characterize the planet’s geology and past climate, to help pave the way for human exploration of the Red Planet and as the first mission to collect and cache Martian rock and regolith.
      NASA’s Mars Sample Return Program, in cooperation with ESA (European Space Agency), is designed to send spacecraft to Mars to collect these sealed samples from the surface and return them to Earth for in-depth analysis.
      The Mars 2020 Perseverance mission is part of NASA’s Moon to Mars exploration approach, which includes Artemis missions to the Moon that will help prepare for human exploration of the Red Planet.
      NASA’s Jet Propulsion Laboratory, which is managed for the agency by Caltech, built and manages operations of the Perseverance rover.

      Current brake system technology cool disc brakes with air pulled from inside the vehicle’s body to prevent overheating. The channels cut into the exterior of the disc brakes developed by Orbis Brakes draw in external air, which is cooler, ensure the brakes work more efficiently.Credit: Orbis Brakes Inc Just as NASA needs to reduce mass on a spacecraft so it can escape Earth’s gravity, automotive manufacturers work to reduce weight to improve vehicle performance. In the case of brake rotors, lighter is better for a vehicle’s acceleration, reliable stopping, and even gas mileage. Orbis Brakes Inc. licensed a NASA-patented technology to accomplish that and more. This revolutionary brake disc design is at least 42% lighter than conventional cast iron rotors, with performance comparable to carbon-ceramic brakes.

      Jonathan Lee, structural materials engineer at NASA’s Marshall Space Flight Center in Huntsville, Alabama, uses his skills as a mechanical designer backed with material science training on multiple projects including the Space Launch System and the International Space Station. Interested in supporting NASA’s other mission to advance technology to improve life on Earth, he was looking for an innovative way to design a better automobile disc brake.

      He started with a single disc with a series of small fins around the central hub. As they spin, these draw in air and push it across the surface of the disc, where the brake pads make contact. This cools the rotor, as well as the brake pads and calipers. He then added several long, curved depressions around the braking surfaces, radiating from the center to create the regular, periodic pattern that gives the new technology, known as Orbis, its PeriodicWave brand name.

      The spinning fins and the centrifugal force of the wheel push air into trenches, causing a turbulent airflow that draws away heat. These trenches in the braking surfaces also increase the available surface for air cooling by more than 30% and further reduce the weight of the disc. They also increase friction in the same way that scoring concrete makes steps safer to walk on – the brake pads are less likely to slip, which makes braking more reliable.

      The troughs draw away more than just heat, too. Water and road debris getting between the pad and rotor are equally problematic, so the grooves provide a place for the air vortex to push any substance out of the way. A small hole machined at the end of each one creates an opening through which unwanted material can escape. 

      The expertise developed while solving problems in space has proven useful on Earth, too. Orbis’s brakes are sold as aftermarket modifications for high performance cars like the Ford Mustang, as well as some Tesla models.

      The north polar region of Jupiter’s volcanic moon Io was captured by NASA’s Juno during spacecraft’s 57th close pass of the gas giant on Dec. 30, 2023. Data from recent flybys is helping scientists understand Io’s interior. Image data: NASA/JPL-Caltech/SwRI/MSSS
      Image processing by Gerald Eichstädt A new study points to why, and how, Io became the most volcanic body in the solar system.
      Scientists with NASA’s Juno mission to Jupiter have discovered that the volcanoes on Jupiter’s moon Io are each likely powered by their own chamber of roiling hot magma rather than an ocean of magma. The finding solves a 44-year-old mystery about the subsurface origins of the moon’s most demonstrative geologic features.
      A paper on the source of Io’s volcanism was published on Thursday, Dec. 12, in the journal Nature, and the findings, as well as other Io science results, were discussed during a media briefing in Washington at the American Geophysical Union’s annual meeting, the country’s largest gathering of Earth and space scientists.
      About the size of Earth’s Moon, Io is known as the most volcanically active body in our solar system. The moon is home to an estimated 400 volcanoes, which blast lava and plumes in seemingly continuous eruptions that contribute to the coating on its surface. 
      This animated tour of Jupiter’s fiery moon Io, based on data collected by NASA’s Juno mission, shows volcanic plumes, a view of lava on the surface, and the moon’s internal structure. NASA/JPL-Caltech/SwRI/Koji Kuramura/Gerald Eichstädt Although the moon was discovered by Galileo Galilei on Jan. 8, 1610, volcanic activity there wasn’t discovered until 1979, when imaging scientist Linda Morabito of NASA’s Jet Propulsion Laboratory in Southern California first identified a volcanic plume in an image from the agency’s Voyager 1 spacecraft.
      “Since Morabito’s discovery, planetary scientists have wondered how the volcanoes were fed from the lava underneath the surface,” said Scott Bolton, Juno principal investigator from the Southwest Research Institute in San Antonio. “Was there a shallow ocean of white-hot magma fueling the volcanoes, or was their source more localized? We knew data from Juno’s two very close flybys could give us some insights on how this tortured moon actually worked.”
      The Juno spacecraft made extremely close flybys of Io in December 2023 and February 2024, getting within about 930 miles (1,500 kilometers) of its pizza-faced surface. During the close approaches, Juno communicated with NASA’s Deep Space Network, acquiring high-precision, dual-frequency Doppler data, which was used to measure Io’s gravity by tracking how it affected the spacecraft’s acceleration. What the mission learned about the moon’s gravity from those flybys led to the new paper by revealing more details about the effects of a phenomenon called tidal flexing.
      This five-frame sequence shows a giant plume erupting from Io’s Tvashtar volcano, extending 200 miles (330 kilometers) above the fiery moon’s surface. It was captured over an eight-minute period by NASA’s New Horizons mission as the spacecraft flew by Jupiter in 2007.NASA/Johns Hopkins APL/SwRI Prince of Jovian Tides
      Io is extremely close to mammoth Jupiter, and its elliptical orbit whips it around the gas giant once every 42.5 hours. As the distance varies, so does Jupiter’s gravitational pull, which leads to the moon being relentlessly squeezed. The result: an extreme case of tidal flexing — friction from tidal forces that generates internal heat.
      “This constant flexing creates immense energy, which literally melts portions of Io’s interior,” said Bolton. “If Io has a global magma ocean, we knew the signature of its tidal deformation would be much larger than a more rigid, mostly solid interior. Thus, depending on the results from Juno’s probing of Io’s gravity field, we would be able to tell if a global magma ocean was hiding beneath its surface.”
      The Juno team compared Doppler data from their two flybys with observations from the agency’s previous missions to the Jovian system and from ground telescopes. They found tidal deformation consistent with Io not having a shallow global magma ocean.
      “Juno’s discovery that tidal forces do not always create global magma oceans does more than prompt us to rethink what we know about Io’s interior,” said lead author Ryan Park, a Juno co-investigator and supervisor of the Solar System Dynamics Group at JPL. “It has implications for our understanding of other moons, such as Enceladus and Europa, and even exoplanets and super-Earths. Our new findings provide an opportunity to rethink what we know about planetary formation and evolution.”
      There’s more science on the horizon. The spacecraft made its 66th science flyby over Jupiter’s mysterious cloud tops on Nov. 24. Its next close approach to the gas giant will occur 12:22 a.m. EST, Dec. 27. At the time of perijove, when Juno’s orbit is closest to the planet’s center, the spacecraft will be about 2,175 miles (3,500 kilometers) above Jupiter’s cloud tops and will have logged 645.7 million miles (1.039 billion kilometers) since entering the gas giant’s orbit in 2016.

      The telescope and instruments for NASA’s Nancy Grace Roman Space Telescope were recently integrated together on the observatory’s instrument carrier at the agency’s Goddard Space Flight Center in Greenbelt, Md. Next, the entire system will be joined to the Roman spacecraft. NASA/Chris Gunn NASA’s Nancy Grace Roman Space Telescope team has successfully integrated the mission’s telescope and two instruments onto the instrument carrier, marking the completion of the Roman payload. Now the team at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, will begin joining the payload to the spacecraft.
      “We’re in the middle of an exciting stage of mission preparation,” said Jody Dawson, a Roman systems engineer at NASA Goddard. “All the components are now here at Goddard, and they’re coming together in quick succession. We expect to integrate the telescope and instruments with the spacecraft before the year is up.”
      Engineers first integrated the Coronagraph Instrument, a technology demonstration designed to image exoplanets — worlds outside our solar system — by using a complex suite of masks and active mirrors to obscure the glare of the planets’ host stars.
      Then the team integrated the Optical Telescope Assembly, which includes a 7.9-foot (2.4-meter) primary mirror, nine additional mirrors, and their supporting structures and electronics. The telescope will focus cosmic light and send it to Roman’s instruments, revealing billions of objects strewn throughout space and time. Roman will be the most stable large telescope ever built, at least 10 times more so than NASA’s James Webb Space Telescope and 100 times more than the agency’s Hubble Space Telescope. This will allow scientists to make measurements at levels of precision that can answer important questions about dark energy, dark matter, and worlds beyond our solar system.
      Technicians install the primary instrument for NASA’s Nancy Grace Roman Space Telescope, called the Wide Field Instrument (at left), in the biggest clean room at the agency’s Goddard Space Flight Center in Greenbelt, Md. This marked the final step to complete the Roman payload, which also includes a Coronagraph instrument and the Optical Telescope Assembly.NASA/Chris Gunn With those components in place, the team then added Roman’s primary instrument. Called the Wide Field Instrument, this 300-megapixel infrared camera will give Roman a deep, panoramic view of the universe. Through the Wide Field Instrument’s surveys, scientists will be able to explore distant exoplanets, stars, galaxies, black holes, dark energy, dark matter, and more. Thanks to this instrument and the observatory’s efficiency, Roman will be able to image large areas of the sky 1,000 times faster than Hubble with the same sharp, sensitive image quality.
      “It would be quicker to list the astronomy topics Roman won’t be able to address than those it will,” said Julie McEnery, the Roman senior project scientist at NASA Goddard. “We’ve never had a tool like this before. Roman will revolutionize the way we do astronomy.”
      The telescope and instruments were mounted to Roman’s instrument carrier and precisely aligned in the largest clean room at Goddard, where the observatory is being assembled. Now, the whole assembly is being attached to the Roman spacecraft, which will deliver the observatory to its orbit and enable it to function once there.
      At the same time, the mission’s deployable aperture cover — a visor that will shield the telescope from unwanted light — is being joined to the outer barrel assembly, which serves as the telescope’s exoskeleton.
      “We’ve had an incredible year, and we’re looking forward to another one!” said Bear Witherspoon, a Roman systems engineer at NASA Goddard. “While the payload and spacecraft undergo a smattering of testing together, the team will work toward integrating the solar panels onto the outer barrel assembly.”
      That keeps the observatory on track for completion by fall 2026 and launch no later than May 2027.

      The Nancy Grace Roman Space Telescope is managed at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, with participation by NASA’s Jet Propulsion Laboratory and Caltech/IPAC in Southern California, the Space Telescope Science Institute in Baltimore, and a science team comprising scientists from various research institutions. The primary industrial partners are BAE Systems Inc. in Boulder, Colorado; L3Harris Technologies in Rochester, New York; and Teledyne Scientific & Imaging in Thousand Oaks, California.
