This photo shows the Optical Telescope Assembly for NASA’s Nancy Grace Roman Space Telescope, which was recently delivered to the largest clean room at the agency’s Goddard Space Flight Center in Greenbelt, Md.NASA/Chris Gunn NASA’s Nancy Grace Roman Space Telescope is one giant step closer to unlocking the mysteries of the universe. The mission has now received its final major delivery: the Optical Telescope Assembly, which includes a 7.9-foot (2.4-meter) primary mirror, nine additional mirrors, and supporting structures and electronics. The assembly was delivered Nov. 7. to the largest clean room at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, where the observatory is being built.
The telescope will focus cosmic light and send it to Roman’s instruments, revealing many billions of objects strewn throughout space and time. Using the mission’s Wide Field Instrument, a 300-megapixel infrared camera, astronomers will survey the cosmos all the way from the outskirts of our solar system toward the edge of the observable universe. Scientists will use Roman’s Coronagraph Instrument to test new technologies for dimming host stars to image planets and dusty disks around them in far better detail than ever before.
“We have a top-notch telescope that’s well aligned and has great optical performance at the cold temperatures it will see in space,” said Bente Eegholm, optics lead for Roman’s Optical Telescope Assembly at NASA Goddard. “I am now looking forward to the next phase where the telescope and instruments will be put together to form the Roman observatory.”
In this photo, optical engineer Bente Eegholm inspects the surface of the primary mirror for NASA’s Nancy Grace Roman Space Telescope. This 7.9-foot (2.4-meter) mirror is a major component of the Optical Telescope Assembly, which also contains nine additional mirrors and supporting structures and electronics.NASA/Chris Gunn Designed and built by L3Harris Technologies in Rochester, New York, the assembly incorporates key optics (including the primary mirror) that were made available to NASA by the National Reconnaissance Office. The team at L3Harris then reshaped the mirror and built upon the inherited hardware to ensure it would meet Roman’s specifications for expansive, sensitive infrared observations.
“The telescope will be the foundation of all of the science Roman will do, so its design and performance are among the largest factors in the mission’s survey capability,” said Josh Abel, lead Optical Telescope Assembly systems engineer at NASA Goddard.
The team at Goddard worked closely with L3Harris to ensure these stringent requirements were met and that the telescope assembly will integrate smoothly into the rest of the Roman observatory.
The assembly’s design and performance will largely determine the quality of the mission’s results, so the manufacturing and testing processes were extremely rigorous. Each optical component was tested individually prior to being assembled and assessed together earlier this year. The tests helped ensure that the alignment of the telescope’s mirrors will change as expected when the telescope reaches its operating temperature in space.
Then, the telescope was put through tests simulating the extreme shaking and intense sound waves associated with launch. Engineers also made sure that tiny components called actuators, which will adjust some of the mirrors in space, move as predicted. And the team measured gases released from the assembly as it transitioned from normal air pressure to a vacuum –– the same phenomenon that has led astronauts to report that space smells gunpowdery or metallic. If not carefully controlled, these gases could contaminate the telescope or instruments.
Upon arrival at NASA’s Goddard Space Flight Center, the Optical Telescope Assembly for the agency’s Nancy Grace Roman Space Telescope was lifted out of the shipping fixture and placed with other mission hardware in Goddard’s largest clean room. Now, it will be installed onto Roman’s Instrument Carrier, a structure that will keep the telescope and Roman’s two instruments optically aligned. The assembly’s electronics box –– essentially the telescope’s brain –– will be mounted within the spacecraft along with Roman’s other electronics.NASA/Chris Gunn Finally, the telescope underwent a month-long thermal vacuum test to ensure it will withstand the temperature and pressure environment of space. The team closely monitored it during cold operating conditions to ensure the telescope’s temperature will remain constant to within a fraction of a degree. Holding the temperature constant allows the telescope to remain in stable focus, making Roman’s high-resolution images consistently sharp. Nearly 100 heaters on the telescope will help keep all parts of it at a very stable temperature.
“It is very difficult to design and build a system to hold temperatures to such a tight stability, and the telescope performed exceptionally,” said Christine Cottingham, thermal lead for Roman’s Optical Telescope Assembly at NASA Goddard.
Now that the assembly has arrived at Goddard, it will be installed onto Roman’s Instrument Carrier, a structure that will keep the telescope and Roman’s two instruments optically aligned. The assembly’s electronics box –– essentially the telescope’s brain –– will be mounted within the spacecraft along with Roman’s other electronics.
With this milestone, Roman remains on track for launch by May 2027.
“Congratulations to the team on this stellar accomplishment!” said J. Scott Smith, the assembly’s telescope manager at NASA Goddard. “The completion of the telescope marks the end of an epoch and incredible journey for this team, and yet only a chapter in building Roman. The team’s efforts have advanced technology and ignited the imaginations of those who dream of exploring the stars.”

On Sept. 20, 2024, four students experienced the wonder of space exploration at NASA’s Johnson Space Center in Houston, taking part in an international competition that brought their work to life aboard the International Space Station.
Now in its fifth year, the Kibo Robot Programming Challenge (Kibo-RPC) continues to push the boundaries of robotics, bringing together the world’s brightest young minds for a real-world test of programming, problem-solving, and innovation.
The Kibo Robot Programming Challenge (Kibo-RPC) students tour the Gateway Habitation and Logistics Outpost module at NASA’s Johnson Space Center in Houston.NASA/Helen Arase Vargas The stakes reached new heights in this year’s competition, with 661 teams totaling 2,788 students from 35 countries and regions competing to program robots aboard the orbiting laboratory. Organized by the Japan Aerospace Exploration Agency in collaboration with the United Nations Office for Outer Space Affairs, the challenge provided a unique platform for students to test their skills on a global stage.
Meet Team Salcedo
Representing the U.S., Team Salcedo is composed of four talented students: Aaron Kantsevoy, Gabriel Ashkenazi, Justin Bonner, and Lucas Paschke. Each member brought a unique skill set and perspective, contributing to the team’s well-rounded approach to the challenge.
From left to right are Kibo-RPC students Gabriel Ashkenazi, Lucas Paschke, Aaron Kantsevoy, and Justin Bonner. NASA/Helen Arase Vargas The team was named in honor of Dr. Alvaro Salcedo, a robotics teacher and competitive robotics coach who had a significant impact on Kantsevoy and Bonner during high school. Dr. Salcedo played a crucial role in shaping their interests and aspirations in science, technology, engineering, and mathematics (STEM), inspiring them to pursue careers in these fields.
Kantsevoy, a computer science major at Georgia Institute of Technology, or Georgia Tech, led the team with three years of Kibo-RPC experience and a deep interest in robotics and space-based agriculture. Bonner, a second-year student at the University of Miami, is pursuing a triple major in computer science, artificial intelligence, and mathematics. Known for his quick problem-solving, he played a key role as a strategist and computer vision expert. Paschke, a first-time participant and computer science student at Georgia Tech, focused on intelligence systems and architecture, and brought fresh insights to the table. Ashkenazi, also studying computer science at Georgia Tech, specialized in computer vision and DevOps, adding depth to the team’s technical capabilities.
AstroBee Takes Flight
The 2024 competition tasked students with programming AstroBee, a free-flying robot aboard the station, to navigate a complex course while capturing images scattered across the orbital outpost. For Team Salcedo, the challenge reached its peak as their code was tested live on the space station.
The Kibo-RPC students watch their code direct Astrobee’s movements at Johnson Space Center with NASA Program Specialist Jamie Semple on Sept. 20, 2024.NASA/Helen Arase Vargas The robot executed its commands in real time, maneuvering through the designated course to demonstrate precision, speed, and adaptability in the microgravity environment. Watching AstroBee in action aboard the space station offered a rare glimpse of the direct impact of their programming skills and added a layer of excitement that pushed them to fine-tune their approach.
Overcoming Challenges in Real Time
Navigating AstroBee through the orbital outpost presented a set of unique challenges. The team had to ensure the robot could identify and target images scattered throughout the station with precision while minimizing the time spent between locations.
The Kibo-RPC students watch in real time as the free-flying robot Astrobee performs maneuvers aboard the International Space Station, executing tasks based on their input to test its capabilities. NASA/Helen Arase Vargas Using quaternions for smooth rotation in 3D space, they fine-tuned AstroBee’s movements to adjust camera angles and capture images from difficult positions without succumbing to the limitations of gimbal lock. Multithreading allowed the robot to simultaneously process images and move to the next target, optimizing the use of time in the fast-paced environment.
The Power of Teamwork and Mentorship
Working across different locations and time zones, Team Salcedo established a structured communication system to ensure seamless collaboration. Understanding each team member’s workflow and adjusting expectations accordingly helped them maintain efficiency, even when setbacks occurred.
Team Salcedo tour the Space Vehicle Mockup Facility with their NASA mentors (from top left to right) Education Coordinator Kaylie Mims, International Space Station Research Portfolio Manager Jorge Sotomayer, and Kibo-RPC Activity Manager Jamie Semple. NASA/Helen Arase Vargas Mentorship was crucial to their success, with the team crediting several advisors and educators for their guidance. Kantsevoy acknowledged his first STEM mentor, Casey Kleiman, who sparked his passion for robotics in middle school.
The team expressed gratitude to their Johnson mentors, including NASA Program Specialist Jamie Semple, Education Coordinator Kaylie Mims, and International Space Station Research Portfolio Manager Jorge Sotomayer, for guiding them through the program’s processes and providing support throughout the competition.
They also thanked NASA’s Office of STEM Engagement for offering the opportunity to present their project to Johnson employees.
“The challenge mirrors how the NASA workforce collaborates to achieve success in a highly technical environment. Team Salcedo has increased their knowledge and learned skills that they most likely would not have acquired individually,” said Semple. “As with all of our student design challenges, we hope this experience encourages the team to continue their work and studies to hopefully return to NASA in the future as full-time employees.”
Pushing the Boundaries of Innovation
The Kibo-RPC allowed Team Salcedo to experiment with new techniques, such as Slicing Aided Hyperinference—an approach that divides images into smaller tiles for more detailed analysis. Although this method showed promise in detecting smaller objects, it proved too time-consuming under the competition’s time constraints, teaching the students valuable lessons about prioritizing efficiency in engineering.
The Kibo-RPC students present their robotic programming challenge to the International Space Station Program. NASA/Bill Stafford For Team Salcedo, the programming challenge taught them the value of communication, the importance of learning from setbacks, and the rewards of perseverance. The thrill of seeing their code in action on the orbital outpost was a reminder of the limitless possibilities in robotics and space exploration.

Artist’s concept of a future airliner based on the NASA Advanced Aircraft Concepts for Environmental Sustainability 2050 submission from awardee Electra. The team’s project focuses on electric propulsion, integrated aircraft technologies, and vehicle design.Electra Picture yourself at an airport a few decades from now. What does your airliner look like? It’s more efficient, with lower emissions than today’s aircraft – what kinds of designs or technology make that possible? NASA is working to answer those questions by commissioning five new design studies looking to push the boundaries of possibility for sustainable aircraft.
Through NASA’s Advanced Aircraft Concepts for Environmental Sustainability (AACES) 2050 initiative, the agency asked industry and academia to come up with studies looking at aircraft concepts, key technologies, and designs that could offer the transformative solutions needed to secure commercial aviation’s sustainable future by 2050. NASA issued five awards, worth a total of $11.5 million, to four companies and one university. These new NASA-funded studies will help the agency identify and select promising aircraft concepts and technologies for further investigations.
Artist’s concept of a future airliner based on the NASA Advanced Aircraft Concepts for Environmental Sustainability 2050 submission from awardee Georgia Institute of Technology. The team’s project focuses on exploring scenarios and technologies based on an aircraft concept the institute has developed, known as ATH2ENA.Georgia Institute of Technology “Through initiatives like AACES, NASA is positioned to harness a broad set of perspectives about how to further increase aircraft efficiency, reduce aviation’s environmental impact and enhance U.S. technological competitiveness in the 2040s, 2050s, and beyond,” said Bob Pearce, NASA associate administrator for the Aeronautics Research Mission Directorate. “As a leader in U.S. sustainable aviation research and development, these awards are one example of how we bring together the best ideas and most innovative concepts from the private sector, academia, research agencies, and other stakeholders to pioneer the future of aviation.”
For decades, NASA has connected government agencies, industry, and academia to develop sustainable aviation technologies. In 2021, NASA launched its Sustainable Flight National Partnership, focused on technologies that could be incorporated into aircraft by the 2030s. The partnership’s research and development led to current NASA work including the experimental X-66 Sustainable Flight Demonstrator aircraft, its Electrified Powertrain Flight Demonstration project, and the development of more efficient engine cores and processes for the rapid manufacturing of lightweight composite materials.

NASA expects the awardees to complete their studies by mid-2026. The new awardee institutions are:
Aurora Flight Sciences, a Boeing Company, whose team will perform a comprehensive, “open-aperture” exploration of technologies and aircraft concepts for the 2050 timeframe. This will include examining new alternative aviation fuels, propulsion systems, aerodynamic technologies, and aircraft configurations along with other technology areas that arise throughout the study. The Electra-led team will explore extending Electra’s novel distributed electric propulsion and its unique aerodynamic design capabilities to develop innovative wing and fuselage integrations that deliver sustainable aviation focused on enabling community-friendly emission reduction, noise reduction, and improved air travel access. The company’s existing small aircraft prototype has been flying for over a year, demonstrating Electra’s technology that aims to transform air travel with reduced environmental impact and improved operational efficiency. Georgia Institute of Technology will perform a comprehensive exploration of sustainability technologies, including alternative fuels, propulsion systems, and aircraft configurations. The institute’s team will then explore new aircraft concepts incorporating the selected technologies with their Advanced Technology Hydrogen Electric Novel Aircraft (ATH2ENA) as a starting point. JetZero will explore technologies that enable cryogenic, liquid hydrogen to be used as a fuel for commercial aviation to reduce greenhouse gas emissions. These technologies will be evaluated on both tube-and wing and JetZero’s blended wing body – an airplane shape that provides more options for larger hydrogen fuel tanks within the aircraft. Pratt and Whitney a division of RTX Corporation, will explore a broad suite of commercial aviation propulsion technologies targeting thermal and propulsive efficiency improvements to reduce fuel consumption and greenhouse gas emissions. The Pratt & Whitney team will then down-select high-priority and alternative propulsion concepts for potential integration studies with various airframe concepts for aircraft in 2050 and beyond.
